This Distribution System Capability

Statement (DSCS) is provided by Muscat

Electricity Distribution Company (MEDC) to

fulfil its regulatory obligations under

Condition number 32 of the MEDC

Distribution and Supply Licence as well as the

Oman Distribution Planning Code 4.4.

MEDC supplies electricity to customers

throughout the Muscat Governate as the

owner and operator of its electricity

distribution system originating from the 33kV

busbars of the Oman Electricity Transmission

Company (OETC) 132/33kV grid stations

down to the final customer’s point of

connection; which incorporates 33kV, 11kV

and Low Voltage (LV) distribution system

voltage levels and associated assets.

The aim of this DSCS is to provide an up-to-date distribution system capability for the next three

years (2020-2022) along with data to enable customers in identifying parts of the system; which

offer opportunities for future connections or upgrading of existing connections to the MEDC system

and where constraints currently exist or potentially could exist in future.

In addition to the required data made available annually as part of DSCS; MEDC additionally has

provided improved detailed system connectivity and additional technical asset data, impact analysis

of Cost Reflective Tariff (CRT) on MEDC customers and an overview of the photovoltaic (PV)

system penetration in the MEDC distribution system which is gaining momentum in our licence area

as well. These additions are expected to provide customers and other stakeholders with a

transparent understanding of MEDC distribution system and operational overview, sufficient

technical parameters to undertake initial system capabilities assessment and the overall distribution

system development.

MEDC have determined this three-year plan to clarify and highlight MEDC’s key priorities over the

DSCS planning period. The plan will form the basis for the company’s investments to provide

economic and efficient system development along with serving to inform MEDC’s contributions to

the Oman electricity sector.

MEDC Distribution System Capability Statement (2020-2022) – V1.0 9

1 . I N T R O D U C T I O N

1.1. Purpose of the Statement

The information in the Distribution System Capability Statement (DSCS) is published annually to fulfil

MEDC regulatory obligation under Condition 32 of its Distribution and Supply Licence (D&SL) and

Distribution planning code 4.4 of the Oman Distribution Code.

This DSCS is intended to provide an understanding of MEDC’s 33kV, 11kV and LV distribution system

along with presenting MEDC’s development plans for the 33kV and 11kV distribution system for the

years 2020-2022. This statement includes power system data for the station loads, overhead lines,

cable circuits, transformers, switchgear and capacitors which forms the MEDC distribution system and

used in the preparation of distribution system models for the power system studies. The results of

load flow, short circuit studies and system technical losses are presented thereby providing an

assessment of the capability of the distribution system.

Implementation of the system development plans is necessary to meet future forecast demand growth,

maintain and/or improve the capability in the distribution system to meet the system growth and to

address the issues of actual or forecast non-compliance with the Distribution System Security

Standard (DSSS). Implementation of these plans will enhance the available system capacity as well

as potentially increase the number of 33/11.5kV primary substations (PSS) providing enhanced

opportunities for new and increased customer connections.

The impact of MEDC’s forecast demand growth and distribution system development plans on the

Transmission System, which is owned and operated by Oman Electricity Transmission Company

(OETC), has been fully assessed in the development of MEDC’s development plans. Where

appropriate 33kV load transfers from one 132/33kV grid substation (GSS) to another are feasible they

have been considered and where this option is not feasible; applications for additional 132/33kV GSS

capacity have been submitted to OETC, resulting in OETC plans to construct and build additional

132/33kV GSS capacity within the MEDC licence area.

1.2. Structure of this DSCS

The following summarises the structure of this Distribution System Capability Statement:

• Chapter 2 and Chapter 3 provide relevant information associated with MEDC’s licence obligations,

technical standards and system planning drivers along with distribution system connectivity.

• Chapter 4 provides a summary view of the distribution system, together with details of the 2019

demand profile along with projected demand forecast, CRT impact analysis of MEDC system,

system constraints, update on continuous improvement areas on the system for the DSCS,

template of the complete system asset data published this year and a summary of the required

technical power system analysis of the distribution system.

• Chapter 5 summarises the current levels of connection activity within the MEDC system and

provides an overview of the opportunities/challenges new customers potentially could face whilst

identifying the challenges that MEDC face currently along with measures to address them. It also

details the Photovoltaic (PV) system penetration within the distribution system.


• Chapter 6 provides detail of the MEDC and OETC development projects; proposed over the three-

year period 2020 to 2022 to be undertaken within the MEDC licence area.

• Appendices detail the summary of the estimated Distribution System Security Standard (DSSS)

non-compliances, PV system connections; results of the associated power system studies and a

complete set of technical data for the 33kV Circuits and Primary Transformers.


2 . P L A N N I N G P H I L O S O P H I E S A N D P R A C T I C E S

MEDC recognise that it is fundamental to provide sufficient guidance to enable relevant stakeholders

along with current and potential customers to understand the quality of supply that they may receive

from the distribution system; also to enable any person seeking a connection to the system to be able

to understand the distribution system at the intended point of connection.

The DSCS below briefly identifies relevant conditions of the Sector Law and the associated Planning

Codes and Security Standards that MEDC as a regulated entity must adhere to. It further outlines the

key technical standards to which MEDC distribution system is designed and constructed to.

Royal Decree 78/2004 promulgated the Law for the Regulation and Privatisation of the Electricity and

Related Water Sector. Article 90 of the D&SL places an obligation on Distribution Companies to

undertake financing, operation, maintenance, development and expansion of the distribution system

in a safe, economic and efficient manner and in accordance with the relevant performance and

security standards.

2.1. Obligations of the Distribution and Supply Licence (D&SL)

Condition 4 of MEDC Distribution Licence as entitled ‘Implementation of and Compliance with the

Distribution Code’; requires MEDC to become and remain a party to and comply with the provisions

of the Distribution Code. It also requires MEDC to co-operate with other Licensed System operators

in the maintenance and development of the Distribution Code.

Distribution Licence Condition 32 is titled ‘Distribution System Capability Statement’ and requires

MEDC to:

‘On an annual basis, prepare a statement in a form approved by the Authority, showing in

respect of each of the three succeeding financial years, circuit capacity, forecast power flows

and loading on each part of its Distribution System and fault levels for each transmission node.’

Licence Condition 32 also describes further information that needs to be included within the DSCS

relating to:

• Information on the status of the Distribution System, its capacity and envisaged future needs.

• Advising potential customers on parts of the system that are best suited to new connections.

• Information on the potential system constraints to development.

• Provide an overview of current system developments.

• Assessment of technical losses.

The full requirements of Licence Condition 32 are found in Appendix A of this document.

The intent of this DSCS is to provide the information as stated above in a form that is relevant and

useful to its customers; Authority for Electricity Regulation (AER) and other stakeholders.


2.2. Requirements of the Distribution Code

The Distribution Code covers all material technical aspects relating to connections to, and the

operation and use of, the distribution system. The Distribution Code is structured into a number of

specific sections.

The Distribution Planning Code (DPC) 2 states that its objectives include for:

‘the exchange of information and interaction between Licensed Distributors and Distribution System

Users concerning any proposed development of Distribution System User Systems that are to be

connected to the Distribution System’.

DPC 4.4 relates to the obligations of MEDC under its Distribution Licence to produce, on an annual

basis, the Distribution System Capability Statement relating to the three succeeding years.

2.3. Distribution System Security Standard

As part of maintaining an adequate electricity supply to our consumers; MEDC is obliged under its

distribution licence to:

‘plan and develop its Distribution System in accordance with the approved Distribution System

Security Standard’1 and to ‘operate and maintain a safe, efficient and economic Distribution

System in accordance with the Security Standards’2.

Table 1 provides a summary of the DSSS classifications.

Table 1 DSSS Classifications and Defined Restoration Times

Class Demand Group First Outage Second Outage

A Less than 2 MW Repair Time No Requirement

B 2MW to 6MW 3 Hours* No Requirement

C 6MW to 20MW Within 15 minutes Restoration time of planned outage

D 20MW to 100MW Immediately Restoration time of planned outage

E Greater than 100MW Immediately Immediately, 2/3 of demand**

*For 11kV networks in remote areas this restoration time may be extended by the time it reasonably takes for a repair crew to

reach the area with the outage as long as the total restoration time will not exceed 6 hours

**Planned Outages area assumed to be restricted to non-summer periods when due to lower ambient temperatures demand

is reduced and equipment ratings enhanced

The DSSS places an obligation on MEDC to restore supply following a circuit or transformer outage

within maximum time limits determined by the total demand within a Demand Group as highlighted in

Table 1.

1 Licence Condition 31 (4a)

2 Licence Condition 31 (4a) and (4b)


A first outage is a fault or planned outage occurring at any time of the year including the period of

maximum demand. A second outage is a fault outage occurring when an integral part of the system

under consideration is not available due to planned maintenance.

The MEDC 33kV system and 33/11.5kV primary substations fall into DSSS classes B to D with the

majority being in Class C.

Primary substations in Class B have a maximum demand between 2MW and 6MW. Following a first

outage the affected load must be re-supplied within 3 hours. This may be achieved by repair and

restoration of the faulted circuit, manual switching at the 33/11.5kV primary substation with two or

more transformers to re-supply customers from an alternative transformer or manual switching of the

11kV network feeders to re-supply customers from an alternative 33/11.5kV primary substation.

Substations in Class C have a maximum demand between 6MW and 20MW. Following a first outage

the affected load must be re-supplied within 15 minutes. This is achieved by the system configuration

and operational control, operating with parallel circuits and remotely operating the circuit breakers

from the MEDC Distribution Control Centre via SCADA.

The majority of existing MEDC 33/11.5kV primary substations have 2 x 20 MVA transformers with a

N-1 firm capacity of 20MVA. These substations fall into the DSSS Class C classification.

33/11.5kV primary substations in Class D have a maximum demand between 20MW and 100MW.

Following a first outage, the affected load must be re-supplied immediately. Immediate restoration

means allowing an adequate time for an interruption followed by restoration through an automated

transfer switching scheme with restoration effected typically within 60 seconds and upto 3 minutes.

Typically, all new primaries constructed are 33/11.5kV primary substations with 3x20MVA

transformers which fall into the Class D classification.

2.4. System Voltage Levels and Configuration

Distribution Connection Conditions Code (DCC) 4.1 states the following:

The voltage on the 33kV,11kV and LV sides of distribution transformers at connection sites with

distribution system users shall normally be controlled within the limits of ± 6.0% of the nominal voltage.

The voltage at customer’s terminals shall not vary from the system nominal voltage +/- allowed

tolerances as shown in Table 2.

Table 2 System Nominal Voltages and Tolerance

Nominal Voltage Level

Tolerance

+6% -6%

33kV 34.98kV 31.02kV

11kV 11.66kV 10.34kV

415V 439.90V 390.10V

240V 254.40V 225.60V


2.5. Frequency Deviations


During normal operating conditions, the nominal system frequency of the transmission and distribution

systems is 50.00 Hz and normally will be controlled by OETC between 49.95 Hz and 50.05 Hz. During

exceptional steady state conditions, frequency deviations will not exceed 49.90 Hz to 50.10 Hz unless

disturbed circumstances prevail. Under disturbed conditions, System Frequency could rise transiently

to 51.50 Hz or fall to 48.00 Hz.

2.6. Voltage Waveform Quality


All apparatus and plant connected to the Distribution System and that part of the Distribution System

at each connection point, must be capable of withstanding the distortions of the voltage waveform in

respect of harmonic content and phase unbalance.

The maximum total levels of harmonic distortion on the Distribution System at 33kV and 11kV, from

all sources under both normal, planned outage and fault outage conditions is required to not exceed

a total harmonic distortion of 2.0%, with no individual harmonic greater than 1.5% unless abnormal

conditions prevail. At Low Voltage (LV) the maximum total levels of harmonic distortion from all

sources is required to not exceed a total harmonic distortion of 2.5%.

The maximum negative phase sequence component of the phase voltage on the Distribution System

should remain below 1.0% unless abnormal conditions prevail.

A maximum value of 2.0% is permitted for phase unbalance.

2.7. Voltage Fluctuations


Voltage fluctuations arising from disturbing or fluctuating loads connected at a connection point to the

distribution system shall not exceed 1.0% of the voltage level for step changes that may occur

repetitively. Any large voltage excursions other than step changes may be allowed up to a level of

3.0% provided that this does not constitute a risk to the distribution system or to any user.

2.8. Auto-reclosing and Single-Phase Protection Operation


Users should be aware that MEDC may use auto-reclosing or automated sequential switching features

on the distribution system. MEDC will on request provide details of the auto-reclosing or sequential

switching features in order that the user may take this into account in the design of the user system

and protection arrangements.

Distribution system users should be aware that the protection arrangements on some distribution

systems may cause disconnection of one phase or two phases only of a three-phase supply for certain

types of fault.


2.9. Design Fault Levels

The design fault levels for the 33kV, 11kV and LV distribution system are stated in OES 11- General

Specifications for Electrical Materials and Equipment and is shown in Table 3.

Table 3 Short Circuit Rating of Switchgear

Voltage Level Rated Short Circuit Capacity

33 kV 25kA (1429 MVA) for 3 sec

11 kV 18.4kA (350 MVA) for 3 sec

11kV (New)* 25kA (476 MVA) for 3 sec

LV 40kA (29MVA) for 1 sec

*Note that MEDC has adopted the standard for new 11kV primary equipment to be 25kA for 3 seconds.

The 33kV system is earthed via a 12.5-ohm neutral earthing resistor connected to the neutral point of

each grid transformer, thereby limiting the maximum prospective 33kV earth fault current to 1,500 A

per transformer. The 11kV system is solidly earthed.

2.10. Standard Equipment Sizes

Conductors

The standard 33kV to LV feeder conductors along with continuous ampere ratings used by MEDC are

as specified in OES 1-33kV and 11kV Overhead Lines and OES 2-33kV & Pilot,11kV & LT

underground cable installations are shown in Table 4, Table 5 and Table 6.

The continuous ampere ratings shown in Table 4, Table 5 and Table 6 are based on typical

manufacturers data and de-rated for the standard installation conditions mentioned in OES 2-33kV &

Pilot,11kV & LT underground cable installations. These ratings ensure safe working on the MEDC

distribution system given the high temperatures experienced during the summer maximum demand

period.

Transformers

Standard 33/11.5kV transformer sizes are specified in OES 6-33/11.5kV Transformers as being 1, 3,

6, 10MVA ONAN and 20MVA ONAF, although other sizes such as 5 and 16MVA do still exist on the

system. The overload capability above the transformer name-plate rating has been confirmed through

modelling3 and supported by a limited number of measurements. MEDC has standardized on 20MVA

ONAF transformers in the urban areas.

MEDC is studying the feasibility of increasing the 33/11.5kV transformer rating for new substations in

areas of high demand density to cope with the high demand growth and the limitation of available land

in such areas.

Standard as a minimum 11/0.433kV ground mounted transformer sizes specified in OES 5-11kV/433V

distribution transformers are 1000, 500, 315, 200 and 100kVA, whereas 1250,1600,2000,2500 and

3000kVA distribution transformers do exist in the network. The most commonly used distribution

transformers in the network are the ground mounted 500, 1000 and 2000kVA units; which form circa

87% of the distribution transformers on the system. The system also has a range of pole mounted

transformers from 50, 100, 200 and 250kVA to be used as required.

Switchgear

Minimum 33kV and 11kV switchgear ratings are specified in accordance to OES 14-11kV Indoor

Switchgear and OES 15-33kV Indoor Switchgear as shown in Table 7.

Table 7 Standard Switchgear Ratings

11kV Bus Section 1200/1250* A

11kV Feeder 400/630* A

*MEDC have adopted and standardised to these based on market availability

Capacitors

All new 125 MVA grid substations are designed with a single 20 MVAr capacitor bank connected to

each 33kV busbar section. All new 20 MVA primary substations are designed with a single 5 MVAr

capacitor bank connected to each 11kV busbar section.

3 Based on IEC 60076-7 calculations


The capacitor banks are as specified in OES 13-11.5kV 5MVAr Capacitor Banks and consist of 5 x

1MVAr units with one set of capacitor banks connected to each bus section. The aim of the capacitors

is to ensure that MEDC maintains power factor and voltage to be within prescribed limits to start with

at the 11kV busbars but certainly at the 33kV busbars in accordance to the Grid Code.

2.11. Technical Standards

In order that MEDC can operate a safe and efficient electricity distribution system all apparatus and

plant associated with the connection to the distribution system are required to comply with the

following standards, as applicable:

(a) Health and Safety Rules;

(b) Oman Electrical Standards (OES), which are such national standards as may be approved by and

amended by the AER as necessary;

(c) Grid Code;

(d) Distribution Code;

(e) The standards and recommendations of the International Standards Organisation and the

International Electro Technical Commission (IEC); and

(f) national standards and codes, which are accepted internationally.

2.12. Specification of Apparatus and Plant

The specifications of all connected plant are required to allow the safe operation of the MEDC

distribution system within its operational procedures. Details of this can be obtained by contacting

MEDC directly.

regard to fault carrying capabilities including making and breaking duties. As necessary MEDC will

provide additional details of the system at the point at which a specific connection is to be made.

Apparatus and plant must be operated within the thermal rating conditions contained in the appropriate

standards, specifications, and other relevant publications, taking into account its intended use. Upon

request MEDC will provide this information .

2.13. Earthing

MEDC will provide advice on the method of earthing of the distribution system, for example, whether

it is connected solidly to earth or through impedance. The specification of associated apparatus and

plant of the connected customer equipment must meet the voltages that will be imposed on the

apparatus and plant as a result of the method of earthing. The method of earthing must comply with

the requirements of Distribution Connections Code Cl 5.2.1.

Users should take precautions to limit the occurrence and effects of circulating currents in respect of

the neutral points connected with Earth where there is more than one earthed neutral point.


2.14. Voltage regulation and control

Any extension or Connection to the distribution system should be designed so as to not adversely

affect the voltage control employed by MEDC on the distribution system. MEDC will make information

on the voltage regulation and control arrangements available if requested by the User.

2.15. Protection

MEDC’s system and the system of any User must incorporate protective devices to ensure that

apparatus and plant with electrical faults are disconnected from the system promptly and that the

effects of faults on one system do not impose unreasonable risks to other systems.

To ensure satisfactory operation of the distribution system; protection systems, operating times,

discrimination and sensitivity at the ownership boundary must be agreed between MEDC and the User

during the process of application for Connection and may be reviewed from time to time by MEDC

with the agreement of the User.

Back-up protection by operation of other circuit breakers or apparatus and plant having a similar

function must normally be provided to safeguard the system against a circuit breaker, or apparatus

and plant having a similar function, failing to operate correctly to interrupt the fault current on a high

voltage system. During the process of application for Connection, MEDC will advise the User if back-

up protection is not required.

Users must not use protection or associated equipment to limit the fault current infeed to the

distribution system unless expressly permitted by MEDC to avoid protection operation malfunctioning

loading to system assets exceeding short-circuit ratings.

3.1. Background

MEDC’s electricity distribution system serves around 398,364 customers (as of July 2019) over an

approximate area of 3,900 sq.km and is divided into three geographic zones. Figure 1 represents an

overview of the MEDC distribution system within the Muscat Governorate including the system

boundaries, zones, the GSS and 33/11kV circuits. The characteristics of the distribution system within

the MEDC licence areas differ mainly because of three major parameters:

1) The load density;

2) The type and usage pattern of the customer;

3) The majority type of feeder circuits (i.e. overhead or underground).

The 2019 maximum demand4 recorded for MEDC system was 2479.2 MW (2609.7 MVA on Sunday

- 30th June 2019 at 14:49 Hrs).

The total existing number of 132/33kV grid substations is 345, 33/11.5kV primary substations

connected to the MEDC distribution system is 179 with a Total Installed Capacity of 6,624 MVA and

a firm capacity of 3,735.5 MVA. The tables identifying each Primary Substation capacity and current

demand can be found in the Appendix D.

The sections remaining from this chapter provide the following:

1) An indicative geographical view of the complete MEDC distribution system and zone wise view of

the grid substations, primary substations, 33kV and 11kV circuits;

2) A summary of the individual zone built up and the planning drivers for each zone;

3) It also provides an overview of the complete current MEDC system connectivity including the area

classification for the primaries.

Area name classification in Table 8-Table 10 below refers to the area what that PSS falls under and

hence the associated Compound Annual Growth Area (CAGR) % being applied to that PSS. The

concept of CAGR % and the area classification are explained in detail in Section 4.1.

4 The 2019 OETC system maximum demand day was the same day as well (30th June 2019;afternoon at 14:55 Hrs).

5 The summation of the GSS in the table 8-10 shows 33 as two GSS namely Airport Height and Misfah are duplicated due to the dual feeder

arrangements.

3.2. Zone 1 – (The Eastern Zone)

The Zone 1 region includes the capital city of Muscat, Muttrah and an extensive rural network, which

covers the wilayats of Amerat and Quriyat. The number of customers served in the Zone 1 region is

126,956 which is approximately 32% of the total customer population. Figure 2 below provides the

geographical overview of the primary MEDC distribution system in Zone 1.

Figure 2 Zone 1 Distribution System with PSS


Amerat has seen the highest demand growth for the last 4 years within the Zone 1 region validating for

a significant demand growth forecasted for the current planning horizon.

The Muttrah Tourism Development project along with Yitty Tourism Development and Fins Project are

the major upcoming development projects in the planning horizon of this DSCS as of yet. Table 8 below

provides the GSS and primary distribution system connectivity for Zone 1.

MEDC is authorized to undertake all regulated activities of electricity distribution and supply business

at 33kV and below across the whole area of Muscat including Seeb, Bousher, Muscat, Muttrah, Amerat

and Quriyat Wilayats.

The distribution system has three nominal voltages; i.e. 33kV, 11kV and 415V.

Most customers connect at LV (415 Volt) and there are bulk customers connected at 11kV and 33kV.

Similarly there are 4 no. large customers connected on the OETC 132kV side but are MEDC customers

for the purposes of energy supply and billing.

4.1. Existing Distribution System

The existing MEDC distribution system asset statistics including the installed capacities are as shown

in Table 11 (as of July 2019).

MEDC system. Over the previous 7 years, MEDC has seen significant growth in specific areas16. The

Compound Annual Growth Rate [CAGR]% for the year 2012-2019 has been used to inform our demand

13 The GSSs with 4x125 MVA configuration are counted as two grids.

14 Max.Load - based on summation of individual primary substation loads occurring at different times; hence is different from the MEDC system

level maximum demand of 2609.7MVA which is summation of primary demands on the system maximum demand day/time.

15 Unaudited figure for 2019 as an indication only. 16 The areas are defined on geographical and electrical connectivity basis as ratified by the zonal teams.


forecast going forward to 2022. In the below table a negative CAGR % indicates no growth in the past

years hence for the purposes of load forecasting a zero load growth will be applied on those areas.

4.2. System Demand and Load Duration

The Maximum and Minimum Demand for the MEDC distribution system in 2019 is illustrated in Table

14 below. This shows that the 2019 minimum demand is circa 25.5% of the 2019 maximum demand

for the MEDC system.

17 The CAGR% used for Misfah is based on an area with similar load characteristics as are created post 2014.


Table 14 Maximum and Minimum System Demands

System Demand

Load (MW) Load (MVA) Date & Time

Maximum 2479.2 2609.7 30th June 2019 @ 14:49 Hrs

Minimum 631.4 664.6 9th February 2019 @ 04:00

Hrs

MEDC note that the date of system maximum demand has fluctuated throughout the years. System

maximum demand has occurred generally between the summer months starting from May to July;

although there seems to be no exact co-relation on the exact timing as expected. There are various

parameters which affect the occurrence of the system maximum demand and we expect more

parameters in the upcoming future especially due to the macro-economic condition of the Oman

economy and due to the developments in newer technologies; but few of the significant ones which

have impacted MEDC distribution system growth in 2019 are :

1) Temperature and Humidity;

2) Customer nos and types of customer growth;

3) Socio-economic factors like occurrence of Ramadan and state of economy due to oil prices;

4) Implementation of CRT.

This can result in a lack of consistent predictability as to the precise date of future system peaks;

although provides a good indication in general of the period and pattern. For this reason; associated

demand transfers are operationally planned to occur before May period each year to ensure MEDC are

in the best position possible to meet regulatory requirements and ensure quality and security of supply

to consumers.

Figure 5 below indicates that from the historical data [2012-2019]; the system maximum demand day

load profile pattern is generally consistent with each other18. As it can be seen from Figure 7; the

maximum demand % growth i.e. growth magnitude has been inconsistent especially between 2013 and

2019; due to the factors mentioned above.

The maximum demand data is supplemented with the associated load duration curve shown in Figure

6. This graph below represents a period of last 9 months (Jan – Sept 2019). The peak demand was

circa 70% of the firm capacity [3,735.5MVA / pf (0.95) =3548.7MW] and the system load is greater than

1500MW for circa 49% of the time during the measurement period as indicated in Figure 6 below. The

associated distribution and utilisation of MEDC’s distribution assets are seen to be generally in line with

common distribution utility practice.

Figure 6 Load Duration Curve

Similar to the system maximum demand, the date of system minimum demand has fluctuated

throughout the years. System minimum demand has occurred generally between the winter months

starting from January to February between 03:00 AM to 05:00 AM. Figure 7 illustrates that the system

maximum/minimum demand including grid connected customers and total customer nos. have steadily

grown year on year following a similar growth trend.

4.3. Cost Reflective Tariff (CRT)

In October 2016, The Regulator announced that the Council of Ministers had approved the introduction

of a new tariff for high value customers called the Cost Reflective Tariff (CRT) and implemented fully in

2017. The new tariff is designed to more accurately reflect the actual costs of providing a supply of

electricity to large government, commercial and industrial customers without government subsidy. The

current approval for CRT implementation is for application only to the high value customers who

consume 150 MWh and above in a year, for the above-mentioned customer categories.

As the full 2019 cycle hasn’t been completed yet an impact analysis was undertaken on 2018 MEDC

customer base to understand the full year impact of CRT on the MEDC distribution system and

described as below.

The number of CRT customers in 2018 was 4916, circa 1.2% of the total connected customers and as

shown in Figure 8 this 1.2% of the CRT customers out of the MEDC total customer base consumed

38% of total energy distributed by MEDC in 2018 as shown in Figure 8.

Figure 8 MEDC 2018 CRT and Non-CRT Units Sold (MWh)

Post implementation of the CRT; the revenue realization per MWh for 2018 MEDC CRT customers was

24.60 OMR. The economic cost of electricity supply in MEDC was approximately 27.5 OMR per MWh

in 2018; hence this results in a government subsidy of 2.9 OMR per MWh for CRT customers. As a total

this resulted in a government subsidy of 12.6M OMR for CRT customers in 2018 compared to 15.0M

OMR in 2017 resulting in net reduction for government subsidies.

The average realization rate across all customers (non-CRT to CRT from 2018) per MWh for MEDC in

2018 was 17.73 OMR/MWh compared to 17.90 OMR/MWh in 2017.

The effect of CRT implementation on the MEDC system maximum demand profile is quite evident in

the form of peak shaving; especially due to the industrial customers.

From the observed 2019 load curve; on the MEDC system maximum demand (30th June 2019); two

large industrial customers load contribution to the MEDC system maximum demand during the peak

hours (i.e. 1:00 pm to 5:00pm) of the week has been effectively reduced to zero in comparisons to

previous year’s as visible from the demand profile’s as shown in Figure 9. As seen from Figure 9

Industrial customer no.1 load on the MEDC system reduced from the normal circa 7MW during the peak

hours in 2017 to circa 0MW in 2018 and 2019.

4.4. Demand Not Secured (DNS)

As per the licence condition; MEDC is obliged to comply with the DSSS and moreover one of our major

investment drivers for the CAPEX programme is to meet the N-1 operational capability for each Primary

Substation. Figure 10 below provides a trend of the MEDC Demand Not Secured (DNS) MVA

performance; as a measure to show DSSS compliance improvement along with number of Primary

Substations contributing to the DNS. It can be seen that in the recent years the DNS performance in

consistently improving and the unaudited 2019 DNS for MEDC realised is 62.0MVA which is a circa

31% reduction compared to 2018 DNS value of 89.3MVA.

4.5. System Demand Forecast

Accurate and realistic load demand forecasting is critical for the effective operation of the distribution

system and is the principal driver for capital expenditure. Realistic assumptions must be made for

inherent uncertainties in forecasting and the underlying socio-economic factors, such as the sustained

low oil price.

Load growth can vary from year-to-year and is not uniform across the whole system. It is not unusual

to find parts of the system growing at significantly higher rates than for the system as a whole, while

other parts of the system can experience periods of low growth or demand reduction.

MEDC high voltage distribution system operates at 33kV and 11kV, both voltages being standard IEC

voltages. The 33kV system is normally operated with duplicated radial while the 11kV system is

operated as a radial configuration, normally with interconnection through normally open points except

in the more remote areas. The system covers both urban and rural areas and the characteristics depend

on the load density.

Distribution Load Forecasting

MEDC considers the following features are necessary to produce an accurate demand forecast in line

with best practice:

• Accurate and unbiased actual demand data – careful management of data and forecasting model

construction based on sound theoretical grounds that closely fits the sample data.

• Transparency and repeatability – as evidenced by good documentation, including documentation

of the use of judgment, which ensures consistency and minimises subjectivity in forecasts.

MEDC also considers the following elements to be relevant to maximum demand forecasting:

• Independent forecasts – spatial (bottom up) forecasts should be validated by independent system

level (top down) forecasts and both spatial and system level forecasts should be prepared

independently of each other. The impact of macroeconomic and demographic trends is better able

to be identified and forecast in system level data, whereas spatial forecasts are needed to capture

underlying characteristics of specific areas within the system. Generally, the spatial forecasts

should be constrained (or reconciled) to system level forecasts;

• Adjusting for temporary transfers – spatial data is adjusted for historical spot loads arising from

peak load sharing and maintenance, before historical trends are determined;

• Adjusting for discrete block loads – large new developments, such as shopping centres and housing

developments, are incorporated into the forecasts, taking account of the probability that each

development might not proceed. Only block loads exceeding a certain size threshold are included

in the forecasts, to avoid potential double counting, as historical demands incorporate block loads

and general demand growth.

System Demand Growth

Historical data indicates that the demand rate of growth across MEDCs distribution system has slowed

in recent years. This may be attributed to the sustained low price and general macro-economic factors.

Over the 2012 to 2019 period the CAGR % system-wide load growth was as shown in Table 15.


Table 15 CAGR% Evaluation on the System Maximum Day

System Maximum Demand 2012-2019 CAGR system load

growth %

Non-Grid connected customers 4.7%

Grid connected customers 5.0%

After the declaration of maximum and minimum load in 2019, the minimum to maximum load ratio %

was calculated for each PSS. The calculated ratio % of each PSS was then applied in the maximum

forecasted load [2020-2022] to forecast the minimum load.

Table 16 and Figure 11 shows the historical trend in system maximum demand with the forecast

maximum demand over the period 2020 to 2022. Despite the general slowing in demand growth at the

system level, there are areas within the system where maximum demand is forecast to grow well

beyond the system average level, while other parts of the system are forecast to experience no load

growth or a small reduction in maximum demand. This particularly applies to Muscat and Muttrah

(except any potential bulk load connections) where the geography of the area (city area predominantly

domestic property) can be considered saturated with little room for property expansion. Significant

demand growth is expected in the South of Zone 1 and Zone 3, largely due to new developments

associated with urban sprawl towards the edge of the urban growth zone. As a result of this urban

sprawl, we expect to see continued strong growth in the Amerat and Mabelah areas.

Especially, in the last two years the growth at system level has reduced and dropped to 0.8% in 2018

and 4.5% in 2019 as seen in Table 16; MEDC shall closely monitor the growth for the remaining years

of the PCR-5 period and reflect the effects in the coming years as necessary for the reasons below:

1) The period when the reduction is observed is very small to be confident to change the growth % for

the upcoming years; especially that MEDC expect the % growth to change compared to recently

observed in the coming years as the price of oil continues to improve as evident from the 2018 to

2019 maximum demand growth;

2) Secondly we expect additional parameters like new technologies; photovoltaics and electric-

vehicles to impact the pattern of the growth;

3) Lastly as also observed from the table below in periods 2010-2012 and 2013-2015 have seen

drastic swings in the system growth percentage due to a multitude of factors in a very short period

of time i.e. MEDC believe that a larger period is required to determine the future growth percentage

rather than last 2-3 years only.

4.6. Grid Supply Points

By 2023, it is forecasted that there will be 38 grid supply points within the MEDC licenced area. There

are 3 new and/or upgraded grid supply points currently in the construction phase. The investment

drivers for grid supply points is to relieve existing overloaded (above the firm) grid supply points and to

provide new 33kV connection points to accommodate new primary substations. MEDC provides

annually a demand forecast for five years to OETC. The existing system (2019) and expected system

development for the primary substations is updated in Figure 12 and Figure 13 [expansion for the next

3 years].

4.7. Distribution System Modelling and Analysis

MEDC maintains up-to-date models of its power system for assessing distribution system performance

via power system studies, bulk loads modelling and undertaking customer connection studies where

required; to ensure the distribution system operates in a safe and an efficient manner along with

providing the required security of supply to its connected customers.

Power System Models

The planning tool utilised for system modelling and studies is PSS®SINCAL (Power System Simulator®

Siemens Network Calculation). The models for each grid substation with their respective connected

primary substations are established by representing the 33kV system on an electrical connectivity basis.

The system models contain network topology and details in terms of nameplate data for transformers

and their tap changers, capacitor banks and their controllers, conductor types along with associated

lengths and parameters and the non-coincident demand data on individual primary substations.

The load demands are modelled as lumped loads connected to the main 11kV bus bars and segregated

into motoric and non-motoric load types for load flow and fault current calculations. The recorded

maximum (summer) and minimum (winter) demands on each primary substation; derived from MEDC

SCADA system as of 2019 have been used to update the power system models. Forecasting principles

for load determination as mentioned in the previous sections have been adopted to forecast the future

year (2020-2022) maximum and minimum demands.

Under minimum demand conditions; the reactive power support from primary substation and grid

substation capacitor banks is switched off to avoid overvoltages.

Load Flow Analysis

Load flow analysis is undertaken for maximum and minimum demand scenarios to define the

performance of MEDC distribution system during these two-extreme loading scenarios. The analysis

determines the active and reactive power flows in the system, percentage loadings for transformers and

33kV circuits along with the voltage profile at the 11kV and 33kV busbars of the primary substations

under normal circuit operation. Simulations are carried out for the existing (2019) and future 3 years

(2020-2022) for system maximum and minimum loadings.

From the studies of these extreme conditions it is possible to identify where the system is strong and

has spare capacity and conversely, where additional mitigation and/or reinforcement, before new

connections, potentially needs be considered. The maximum demand case for instance; identifies

where there is a risk of overloading, of operation above firm capacity, or of system voltages falling below

the voltage limits whereas the minimum demand case will recognize voltage excursions above statutory

limits as defined in the Distribution Code.

The power factor values for maximum and minimum demand scenarios have been determined based

on the actual available information from MEDC SCADA. For maximum demand conditions; the actual

recorded power factor data is employed, where available, for 120 primary substations. For the remaining

59 substations; where power factor values are not available, a calculated system average of 0.93 is

considered in accordance to the company defined practice.

On similar principles for the minimum demand scenario where the power factor values aren’t available

a calculated system average of 0.89 is considered in accordance to the company defined practice.


The load flow study results are summarised in tabular form in Appendix D and available in a

downloadable excel file that supplements this Distribution System Capability Statement.

The simulation result demonstrates the following:

• Voltage drop under maximum demand scenario remains within the statutory limits of - 6% on all

33kV busbars/nodes.

• Voltage drop under maximum demand scenario remains within the statutory limits of - 6% on all

11kV busbars/nodes.

• Voltage rise under minimum demand scenario remains within the statutory limits of + 6% on all

33kV busbars/nodes.

• Voltage rise under minimum demand scenario remains within the statutory limits of + 6% on all

11kV busbars/nodes; in case of very minor excursions in 2019, the problem solves in forthcoming

years.

• 33kV circuit loadings assessed for the worst-case maximum demand scenario; across the system

are within the acceptable circuit ratings; except for Dhagmar1 Feeder 1 from Quriyat GSS where

by 2021-2022 it reaches 108.8% of the derated circuit capacity. These results are based on non-

coincident maximum demand to represent worst case scenario’s of the connected PSSs on this

feeder. MEDC believe in reality the diversity in the system will ensure that the feeder is not

overloaded and hence will continue to monitor the actual load on this feeder and will prepare

mitigation plan accordingly.

From the results it can be observed that especially under minimum demand case, the 11kV buses at

the primary substations are approaching the statutory limit of +/-6% in some of the primary substations.

This is explained by the fact that our primary transformers are rated at 11.5kV secondary voltage and

to represent the worst case scenario; the load flow calculations are performed with tapchangers

switched off, which on the ground will otherwise regulate the voltage performance better and remain

within statutory voltage limits.

Short Circuit Analysis

MEDC carries out short circuit studies to establish the capability of equipment to withstand three phase

maximum prospective fault current levels.

The principal source of fault currents is the generation system connected to the transmission system

with the fault current contribution onto the MEDC distribution system via the 132/33kV GSS

transformers. The fault current infeed from the OETC source have been updated in our power system

models according to the data provided by the OETC’s 2019 Capability Statement which covers up the

transmission system developments up to 2023.

The system configurations modelled for short circuit studies in each year, to represent the maximum

prospective fault current levels, while also reflecting the realistic operational arrangement are based on

the following principles:


• All existing and new 2x20 MVA PSSs are simulated for operation with the 11kV bus-section circuit

breaker in the “normally closed” position20.

• All existing and new 3x20 MVA PSSs are simulated for operation with one 11kV bus-section circuit

breaker as “normally closed” and one as “normally opened” (i.e. in N or N-1 scenario, it represents

a 4 out of 5 ‘normally closed’ circuit breakers scenario) with an auto-changeover scheme 21.

• All existing 2x20 MVA PSSs and 3x20 MVA PSSs are simulated for operation of 33kV bus-section

circuit breakers within the PSSs (where ever present)22 as “normally open”.

The design short circuit breaking ratings of the 11kV switchgear components at new and upgraded

primary substations have been revised to 25 kA to comply with system requirements23.

Currently, in the absence of accurate fault level contribution data on low voltage (LV) side, a worst-case

allowance is made for LV motor fault contribution majorly due to the nature of the air conditioning load

prevalent across the MEDC’s distribution system. A motoric to static load type ratio of 80/20 (in

percentage) is considered using the system maximum and minimum demand values. System modelling

for fault current calculations have been performed in accordance with the principles of the “IEC 60909-

Short Circuit in 3 phase AC systems” standard.

The maximum prospective fault current values are tabulated in the tables in Appendix D. The calculation

of maximum prospective fault current is compared against the rated breaking capability of the primary

equipment.

The maximum prospective (initial symmetrical) fault current is calculated to be still under but

approaching (i.e. >95% and <100% ) the rated breaking capacity of the primary 33kV equipment

(switchgear) at the following primary substations:

• Bousher Grid Primary - GP02 (24.7 kA in 2019 and then within 95% of 25kA rating)

• Mawalleh South Grid - GP05 (23.8 kA in 2019 and then within 95% of 25kA rating)

• Rusail Industrial 4 - P158 (24.2 kA in 2021 and then within the 95% of 25kA rating)

However, at the following primary substations, minor excursions beyond the rated breaking capacity of

the 33kV equipment (switchgear) are observed :

• MSQ Grid Primary – GP06 (25.7 kA in 2021 and staying >95% of 25kA across all years)

• Mabelah Grid Primary - GP04 (25.5 kA in 2021 and then within 95% of 25kA rating)

where it marginally exceeds by +2.8%, and +2% respectively above the switchgear rating; hence MEDC

shall monitor these PSS closely and create mitigation plans in form of operational restrictions if required

based on the monitoring results.

20 Except for few locations where the 33kV feeders for the individual transformers are connected from two differeng GSSs in which case, the 11kV

bus-section circuit breaker is kept “normally open” for the respective year(s).

21 If the fault levels are within limits for this worst case scenario’s then on bus-coupler open scenario’s of existing primaries the fault level’s will be

even lower.

22 For new PSS, the 33kV configuration excluded 33kV bus-section circuit breakers at the PSS.

23 For the older existing 11kV indoor type switchgear where applicable, the rated breaking short circuit current value is 18.4kA.


It is to be noted that all the above primary substations are in close electrical vicinity of the grids

substations where these results are based on non-coincident maximum demand fault contributions to

represent worst case scenario’s of the connected PSSs on this feeder.

The maximum prospective (initial symmetrical) fault current levels at 11kV busbars of all the primary

substations are within their rated breaking capacities.

Technical Losses Assessment

The technical losses in the MEDC distribution system are a factor of the configuration of the system,

type and specification of equipment, percentage utilisation of assets and customer energy consumption.

Technical losses are attributed to load and no-load losses in the 33kV feeders and 33/11.5kV primary

transformers, 11kV feeders and distribution transformers and the LV distribution system. In line with

standard international practice for utilities where the distribution system is not fully modelled, we

calculate the losses for specific network elements (transformers, overhead lines and cables) across the

different voltage levels (33kV, 11kV and LV) and then summate the total losses to obtain a percentage

technical loss for each primary substation.

The percentage technical losses are then apportioned according to the proportion of total system energy

supplied by each substation. A summation of all apportioned technical losses is then presented as the

system percentage technical losses. The summated technical losses based on the 2019 distribution

system operation is estimated to be 4.01%. The breakdown of technical losses by voltage is shown in

Table 17 below.

Table 17 Technical Losses

System Component Loss Value

33kV Circuits 0.19%

Primary Transformers 0.46%

11kV Circuits 0.48%

Distribution Transformers 1.69%

LV network 1.19%

Total 4.01%

4.8. Continuous Improvement Areas

MEDC have progressed on previously identified areas of continuous improvement as listed below and

is continuing its working on the same along with identifying new areas where required.

1) Bulk Load Details and Modelling

Currently, we are in process of collating the details of existing 33kV and 11kV bulk customers to

incorporate in MEDC power system models as appropriate. In comparison to last year; improved tools

and processes including a creation of a Bulk Load Database to record accurately point of connections,

customer power system impact including short circuit contribution to MEDC distribution system and

agreed capacities to consistently capture these for existing and new customers have been created to

effectively progress in this area. This has led to modelling of further 02 no. bulk loads at 11kV with their

more accurate fault current contributions added to our base master models.


2) 11kV System Modelling

In 2019, MEDC awarded a contract to Siemens PTI Network Consulting who are the owners of MEDC

power system software package PSS®SINCAL for establishing the correct methodology and achieving

MEDC requirements for developing power system models for 11kV system up to the main LV bus bar

for one typical GSS model, namely Bousher GSS. This contract will be finished by end of 2019 post

which, MEDC will take the newly developed methodology and the improved GIS to PSS®SINCAL

adapters developed by MEDC to intiate the development of 11kV models in a more efficient and

automatic manner for the rest of the 33 GSS and associated network. The exports from GIS will be

made based on up-to-date 11kV network information into PSS®SINCAL readable format. This will not

only enable us to improve our existing system studies like fault current level, load flow and technical

losses calculations using PSS®SINCAL but will be supportive in point of connection studies as well.

Point 3 below shows the initial progress for the 11kV system modelling as well to reflect the real

scenarios on ground.

3) Improved and Updated Motoric Short Circuit Contribution

We aim to assess the motor fault contribution onto MEDC’s system at LV due to the connection of

typical larger scale centralised commercial air-con units by obtaining typical details of such systems

from our larger commercial customers and preparing sample equivalent connection impact studies.

We are undertaking assessment studies for MV motor fault contribution from larger industrial customers

in relevant parts of the system to improve the fault current calculations.

To this effect and compared to last year, we have further enhanced our network models at additional

(in addition to Jibrooh-P041 and Mawalleh North Grid-GP01 what we completed last year) 02 x primary

substation sites, Al Khoudh Ph 06 – P049 and Mall of Oman - P171 to appropriately reflect the expected

fault current contribution at 11kV based on manufacturer’s data for the large MV motors from 02 x large

bulk customers namely; Ad-Dakhiliyah Water Pumping Station (representing a fault infeed of 2.84kA at

11kV) and Mall of Oman development (representing a fault infeed of 2.44kA at 11kV) respectively onto

our distribution systems.

MEDC recently in 2019 completed an innovative prospective fault level monitoring project; based on

the actual measured network conditions which has given us initial answers around fault level

contributions from upstream transmission grid as well as downstream motor loads onto LV and MV

networks. We aim to do further monitoring trails to firm up the initial answers going forward and improve

the mortoric short circuit contributions from different types of loads on the distribution system.

4) Technical Losses Calculation using Power System Models

As detailed in point 2 ; once the complete 11kV network models are established which has already been

initiated in 2019 we will merge our 33kV and 11kV models and furnish them with annual load profiles to

produce technical losses from the models using measured loadings from the load profiles.

5) Minimum Scenario Modelling

For the period 2019 to 2022, MEDC has performed the load flow analysis for minimum demand

conditions as well. The future plan is to perform minimum fault current calculations using these models.


6) Voltage Control and Regulation Methodology

As an additional improvement item, MEDC is in process of developing an improved voltage regulation

methodology at our primary substation 11kV busbars by assessing the SCADA data on present/typical

transformer tap positions and capacitor banks during summer and winter times. This is ongoing to

enable us to assess optimal target voltage requirements and capacitor bank operational philosophy on

11kV network starting at the 11kV busbars which will help in improvement of technical losses and better

voltage profile on the extremities of the system. This will also create potential for further economic

development of the system especially in the rural areas with additional extension possibilities provided

by these solutions.

MEDC recognise that the nature of electricity generation and use is changing. We envisage that recent

policy initiatives will result in an increase in photovoltaic (PV) generation on our distribution system.

Unlike other utilities in different regions, Oman has not seen significant uptake in electric vehicle

charging thus, the associated demand characteristics for electric vehicles (EV) are not considered to

be a contributing factor to our system planning in the short term planning horizon. However; this will be

closely monitored to check the penetration rate of EV and PV in general.

With the introduction of Sahim-I initiative by the AER since May 2017 there has been an increasing

uptake of small grid connected PV systems for households and business as evident from the PV

connections list in Appendix C. Similarly with the recent 2019 launch of Sahim-II aimed at encouraging

the small grid connected PV systems (circa 3-5kWp) for residential rooftops; MEDC expect even greater

rate of uptake (AER forecasting circa 10-30% residential premises24). With this great rooftop PV

intiatives, MEDC does foresee challenges and opportunities in the way we will plan and operate our

system. Whilst PV may have the impact of reducing transmission and distribution congestion; we do

envisage that challenges in terms of power quality, reverse power flow and operating within voltage

limits will need to be addressed if PV uptake is significant.

MEDC are responsible for ensuring power quality according to the regulations under which we operate.

However; with the addition of intermittent, consumer-owned and non-dispatchable PV units, current

standard procedures for guaranteeing power quality might not be as effective as they are without PV.

Overvoltage is one of the main reasons for limiting the capacity (active power) of non-dispatchable PV;

that can be connected to a low voltage Distribution System. During high PV generation and low load

periods; there is a possibility of reverse power flow and consequently voltage rise in the HV & LV feeder.

We envisage that this will be most prominent during the winter period. For this reason; MEDC believe

that if uptake is significant it will impact investment decision making for reinforcement and asset

replacement. Consideration of tap range, optimum dispatch of capacitor banks and conductor sizing

may be necessary should PV penetration become high.

5.1. New Connection Applications

MEDC are responsible for the connection of customers for all levels of demand that our system supplies.

We are also the initial point of connection request for customers seeking a 33kV or 132kV connection

at an OETC grid supply point. In 2019, we have received 31 bulk connection requests with a combined

total demand of 431 MW. 11kV and lower voltages connection applications are identified in Table 18.

Photovoltaic (PV) connections

In regard to distributed generation PV connections, MEDC received 14 new applications during 2019

with total requested generation capacity of 1.28 MW. In 2019 11 no. applications (including applications

from 2018 energised in 2019) were connected equating to 1.26MW, 12 no. applications are under

construction (including applications from 2018 which are still under construction) equating to 2.3MW

and 2 initial applications submitted equating to 0.162MW. Table 19 below shows these customer

classifications for the applications and connections. Appendix C, has the complete details of the 2019

5.2. System Constraints and Opportunities

Load related system constraints fall into one of two categories:

• Current constraints that can be considered DSSS obligations.

• Load related constraints based on current load growth forecasts.

MEDC will seek to address such constraints as part of its investment plan. Demand Not Secured (DNS)

non-compliances are identified and documented within Appendix B.

Table 20 provides a list of projected capacity constraints at the end of the planning horizon in 2022. If

the value is identified as negative, MEDC envisage there will be a deficit in spare capacity at that specific

substation, thus it is less advantageous for a customer to consider a new connection in that area.

Likewise, if there is spare capacity (positive), then this substation may be considered more

advantageous as a point for new customer connection.

A P P E N D I X D : S Y S T E M S T U D Y R E S U L T S

Appendix D presents the following series of tables, for each grid substation power system model, which

show the expected performance of the distribution network under maximum and minimum demand

scenarios for each year from 2019 to 2022.

1. Primary Substations Maximum Demand and Percentage Loading

The maximum demand with real and reactive power loads at the PSS individual peak time in 2019

planning cycle and as accordingly forecasted for the period from 2020 to 2022. Percentage loading is

calculated based on the Firm Capacity of the PSS. This data was used in the load flow and fault level

studies for maximum demand scenario presented in this section of this DSCS.

2. Primary Substations Minimum Demand and Percentage Loading

The minimum demand with real and reactive power loads at the PSS individual minimum time in 2019

planning cycle and as accordingly forecasted for the period from 2020 to 2022. This data was used in

the load flow studies for minimum demand scenario presented in this section of this DSCS.

3. 33kV Feeder Loads

The resulting maximum demand in MVA on 33kV circuits/feeders, calculated for the individual non-

coincident maximum loads of the PSS(s) connected to these feeders for the period 2019 to 2022.

Percentage loading is calculated based on the de-rated capacity of the circuits.

4. Primary Substations Bus Voltages

The resulting voltage value (expressed in percentage of the nominal 33kV and 11kV) on the busbars of

the PSSs, corresponding to maximum and minimum demand scenarios.

5. Primary Substation 3-Phase Fault Current Levels (kA)

The resulting 3 phase maximum fault current level on the busbars of the PSSs, corresponding to

maximum demand scenarios. The rated breaking fault ratings of the switchgear are also specified.

Explanatory Notes:

a) 1TX in Firm Capacity means primary substation has single 33/11.5 kV transformer (i.e. zero N-

1 capacity and firm capacity equivalent to 11kV interconnection capacity);

b) Standby PSS means primary substation having 33kV and 11kV busbars energized with 11kV

outgoing feeders (i.e. loads) disconnected. The load on these PSSs is expected to be

connected occasionally, depending on requirement.

In the above mentioned tables, a “-“ (dash) appears in relevant years due to any of the following

reasons, as may be applicable:

− The primary substation is shifted (i.e. connected) to another grid substation;

− The primary substation, or any of its capacity enhancement project, is planned to be

energized/commissioned in the future;

− For Bus Voltages and 3 Phase Fault Current Levels tables, there is no 33kV second busbar or

node, hence 33kV Bus B results dashed out;

− There are no 11kV busbars (rather a different voltage level exists e.g. 6.9kV for a private

customer, operated and maintained by the customer);

− MEDC doesn’t have the information of the network below 33kV level.

Appendix E presents the following series of tables, for each grid substation power system model in form

of complete technical asset data.

Appendix E1 – 33kV Circuits/Feeders Data

Appendix E1 presents the circuit length from gird substation up to the 33kV busbar in the primary

substation. It specifies the key parameters for the circuits including resistance, reactance, capacitance

and the continuous derated thermal rating for the underground cable and overhead line conductor types

used. The resistance is specified at 20C AC values.

Explanatory Notes:

a) 33kV UGC 300 3C Cu means 33kV underground cable of 300 sq.mm. cross-sectional area,

three core type and formed of copper conductor;

b) In general, the cables employed are XLPE insulated and armored;

c) 33kV OHL 200 Panther ACSR means 33kV overhead line of 200 sq.mm. cross-sectional area

(i.e. Panther conductor) of Aluminium Conductor Steel Reinforced type;

d) 33kV OHL 100 Dog ACSR means 33kV overhead line of 100 sq.mm. cross-sectional area (i.e.

Dog conductor) of Aluminium Conductor Steel Reinforced type;

e) Where a single 33kV feeder feeds multiple primary substations [for e.g. circuits in rural areas],

the circuit length between the grid substation and each of the connected primary substation on

that feeder is calculated and captured individually. This means that there will be few duplicated

segments of circuit length. This is explained with the following example:

Hence, the 33kV circuit lengths as documented for;

− PSS 1 = F1-L1

− PSS 4 = F1-L1 + F1-L2 + F1-L3 + F1-L4

− PSS 5 = F1-L1 + F1-L2 + F1-L3 + F1-L5

f) MEDC is currently in process of developing the typical values for zero sequence resistance and

zero sequence reactance for future improvements.

Appendix E2 – Primary Substation Transformer Data

Appendix E2 presents the data used to model the primary substation power transformers for the load

flow and fault current calculation studies. The data comprises of the transformer nameplate data and

includes ONAF power rating, voltage ratio, percentage impedance (based on transformer rating) and

the tap range and step size.

Explanatory Notes:

a) The method of earthing at all the 33/11.5kV primary substations power transformers is ‘solidly

earthed’ except the following where resistance earthing is applied:

− Rusail Housing-P056 PSS

b) MEDC is currently in process of developing the typical values for zero sequence resistance and

zero sequence reactance for future improvements.
