1. EXECUTIVE SUMMARY
This document provides a comprehensive context and description of the KPI definition and
selection procedure, in order to assess the performance of the IDE4L architecture and use cases.
The IDE4L KPI set has been developed using the European Electricity Grid Initiative (EEGI)
methodology as the reference framework for this task. Therefore, the EEGI KPI structure is
introduced and given an ample depiction at the beginning of the deliverable (Chapter 4).
The IDE4L KPIs are going to be used as a fundamental tool for evaluating the Use Cases to be
tested within the project, so a deep analysis of the Use Cases has been performed, and a specific
set of KPIs has been designed for each one.
In the process of crafting KPIs for the IDE4L use cases, two templates have been used:
1. a short one for a first approach of the selection, and
2. a detailed one for a complete definition of the selected ones
The correspondence between Use Cases and KPIs is shown in Chapter 5, whereas their whole
description can be found in Chapter 6.
In Chapter 7, some guidelines for the KPI calculation are given, in order to explain how to use and
make the most of them. This process is defined as a flow chart, starting with the validation of all
the inputs in the different demonstration scenarios, and then continuing with the evaluation of the
KPI. Moreover, a template for the results is designed, in order to standardize and facilitate this
task.
Finally, in order to determine the impact on the DSO business performance of IDE4L project, a map
from IDE4L to EEGI KPIs is drawn.

3. INTRODUCTION
In IDE4L project, 22 Use Cases are going to be tested in different environments: development
laboratories, demonstration laboratories, and field demonstrators. In order to evaluate the
solutions, algorithms and procedures to be tested, a proper methodology has to be defined. This
document aims at deeply describing the methodology defined in IDE4L for the KPIs selection and
definition, and also establishing a set of guidelines to help the calculations.

4. REFERENCE FRAMEWORK FOR KPI DEFINITION
4.1 EEGI methodology
After the analysis of the different frameworks for KPIs using the judgement and experience of the
project participants, the EEGI framework has been adopted as a reference for the IDE4L KPI study,
due to its simplicity and level of development.
EEGI has analysed the energy targets for the future electricity sector decarbonisation, and it has
developed a complete roadmap for 2022, where a set of Key Performance Indicators (KPI) are
defined in order to quantify the proposed goals for a low carbon economy at affordable costs
[EEGI_roadmap].
The EEGI framework is developed under the GRID+ project [grid+], oriented to support the
development of EEGI initiative. With this purpose, three levels of KPIs have been introduced, each
level having a specific management goal of the Research and Innovation Roadmap. These KPIs are
not oriented to evaluate the results of R&I projects, but to estimate their contribution to achieve
the EU goals.
In the following figure, the three EEGI KPI levels are shown:
Figure 1 EEGI KPI levels
Source: EEGI Grid+ project
Level 1: “Overarching KPIs” consist of a set of indicators which trace clear progress brought
by EEGI activities towards its overarching goal
Level 2: “Specific KPIs” include those indicators oriented to quantify the expected impacts
of a group of R&I activities in view of meeting the R&I roadmap overarching goal
Level 3: “Project KPIs” are a set of indicators proposed by each R&I project in view of
detailing further the contribution of each R&I project to level 2 KPIs
In the study of KPIs, some scenarios shall be taken into consideration. First of all, the current
situation must be analyzed as a reference, and then two possible future situations:
IDE4L Deliverable D7.1
12 IDE4L is a project co-funded by the European Commission
Figure 2 Scenarios to be measured
Source: EEGI Grid+ project
Business as Usual (BAU) case: this scenario shows what would be the situation if
conventional solutions are applied (it reflects the normal evolution that the network would
have)
R&I case: this scenario corresponds to a future situation where innovative solutions
provided by R&I project results are implemented. This impact can be technical, economical,
or both of them
Baseline case: reference scenario
Once the scenarios are defined, EEGI proposes a step-by-step methodology to measure the KPIs. It
is a six-step process, defined as it follows:
1 STEP 1: Determination of the reference scenario or initial situation, the problems to
solve, needs to satisfy, and the drivers that trigger a network/system improvement
2 STEP 2: Analysis of the future situation when the conventional evolution of the
network happens (BAU situation)
3 STEP 3: Calculation of the correspondent KPI to evaluate the BAU situation
4 STEP 4: Analysis of the future situation when smart grid solutions are deployed in
the network (R&I situation)
5 STEP 5: Calculation of the correspondent KPI to evaluate the R&I situation
6 STEP 6: Comparison of both scenarios, and calculation of the final indicator
applying the proposed formula
4.2 Overarching KPIs (EEGI Level 1)
The EEGI Roadmap has identified an overarching goal of allowing European electricity networks
continuously deliver effective flexible capacities to integrate actions of grid users at affordable

costs, keeping the system reliability at levels compatible with societal needs. In order to evaluate
the approach of R&I activities to this goal, two KPIs are defined to be applied to clusters of projects:
1. A.1 Increased network capacity at affordable cost
This indicator evaluates the increase/decrease of network capacity at an affordable cost
(NCAC) for all grid-users (generation and demand), wherever and whenever it is necessary,
maintaining an affordable cost, i.e. maximising the added network capacity per euro of
investment. Two different calculations are provided:
a) Variation of the amount of network capacity per euro of cost:
∆𝑁𝐶𝐴𝐶 = 𝑁𝐶𝐴𝐶𝑅&𝐼 − 𝑁𝐶𝐴𝐶𝐵𝐴𝑈 [unit: W/€]
Being 𝑁𝐶𝐴𝐶𝑅&𝐼 = 𝑁𝐶𝑅&𝐼/𝐶𝑅&𝐼 ; and 𝑁𝐶𝐴𝐶𝐵𝐴𝑈 = 𝑁𝐶𝐵𝐴𝑈/𝐶𝐵𝐴𝑈
It can also be expressed in terms of percentage:
∆𝑁𝐶𝐴𝐶% = ((𝑁𝐶𝐴𝐶𝑅&𝐼 − 𝑁𝐶𝐴𝐶𝐵𝐴𝑈)/𝑁𝐶𝐴𝐶𝐵𝐴𝑈) × 100
b) There is the possibility that the R&I project does not provide an improvement of the
network capacity, but a reduction of the cost. In this case, the interesting indicator is the
one proposed:
∆𝐶 = 𝐶𝑅&𝐼 − 𝐶𝐵𝐴𝑈 [𝑢𝑛𝑖𝑡: €]
∆𝐶% = ((𝐶𝑅&𝐼 − 𝐶𝐵𝐴𝑈)/𝐶𝐵𝐴𝑈) × 100 [𝑢𝑛𝑖𝑡: %]
Where:
NC is the Increase in Network Capacity (through BAU or R&I) (increase in the amount of
electrical power that can be transmitted or distributed in the selected frame) [W]
C is the Cost (OPEX and/or CAPEX) [€]
NCAC is the Increase of Network Capacity at Affordable Cost [W/€]
2. A.2 Increased system flexibility at affordable cost
This indicator evaluates the increase/decrease of system flexibility for all grid-users
(generation, loads, and network operators), while avoiding potential instability and
blackouts, keeping an affordable cost. The following general indicator is provided:
∆𝑆𝐹𝐴𝐶 = 𝑆𝐹𝐴𝐶𝑅&𝐼 − 𝑆𝐹𝐴𝐶𝐵𝐴𝑈 [𝑢𝑛𝑖𝑡: 𝑊 𝑜𝑟 𝑀𝑉𝐴𝑟/€]
being 𝑆𝐹𝐴𝐶𝑅&𝐼 = 𝑆𝐹𝑅&𝐼/𝐶𝑅&𝐼
and 𝑆𝐹𝐴𝐶𝐵𝐴𝑈 = 𝑆𝐹𝐵𝐴𝑈/𝐶𝐵𝐴𝑈
IDE4L Deliverable D7.1
14 IDE4L is a project co-funded by the European Commission
It can also be expressed in terms of percentage:
∆𝑆𝐹𝐴𝐶% = ((𝑆𝐹𝐴𝐶𝑅&𝐼 − 𝑆𝐹𝐴𝐶𝐵𝐴𝑈)/𝑆𝐹𝐴𝐶𝐵𝐴𝑈) × 100
Two more indicators are provided, for the following special cases:
a) If the R&I project does not know information about the cost of the innovative solutions
they are testing, the indicator will only take the system flexibility into account:
∆𝑆𝐹 = 𝑆𝐹𝑅&𝐼 − 𝑆𝐹𝐵𝐴𝑈 [𝑢𝑛𝑖𝑡: 𝑊 𝑜𝑟 𝑀𝑉𝐴𝑟]
∆𝑆𝐹% = ((𝑆𝐹𝑅&𝐼 − 𝑆𝐹𝐵𝐴𝑈)/𝑆𝐹𝐵𝐴𝑈) × 100 [𝑢𝑛𝑖𝑡: %]
b) If the R&I project does not provide an improvement of the network capacity, but a
reduction of the cost:
∆𝐶 = 𝐶𝑅&𝐼 − 𝐶𝐵𝐴𝑈 [𝑢𝑛𝑖𝑡: €]
∆𝐶% = ((𝐶𝑅&𝐼 − 𝐶𝐵𝐴𝑈)/𝐶𝐵𝐴𝑈) × 100 [𝑢𝑛𝑖𝑡: %]
Where:
SF = System Flexibility: amount of electrical power (generation and load) that can be
modulated to the needs of the system operation within a specified unit of time [W or
MVAr]
SFAC = System flexibility at affordable cost [W or MVAr/€]
C = OPEX and CAPEX estimated to manage the flexibility of the network [€]
4.3 Specific KPIs (EEGI Level 2)
The overarching goals aforementioned (increasing network capacity and system flexibility) can be
further quantified and monitored through seven specific KPIs; six of them are common for DSOs
and TSOs, and the last one is specific for DSOs only.
Common TSO and DSO Specific KPIs
B.1 Increased RES and DER hosting capacity. B.2 Reduced energy curtailment of RES and DER. B.3 Power quality and quality of supply. B.4 Extended asset life time. B.5 Increased flexibility from energy players. B.6 Improved competitiveness of the electricity
market.
DSO Specific KPI B.7 Increased hosting capacity for electric vehicles (EVs) and other new loads.
IDE4L Deliverable D7.1
15 IDE4L is a project co-funded by the European Commission
These KPIs also cover the functional objectives defined in EEGI Roadmap. They are explained in the
following list:
1 B.1 Increased RES and DER hosting capacity (DSO+TSO)
This KPI is intended to give a statement about the additional RES/DER that can be installed
in the network, when R&I solutions are applied, and compared to the BAU scenario. This
improvement can be quantified by means of the following percentage:
𝐸𝐻𝐶% =𝐻𝐶𝑅&𝐼 − 𝐻𝐶𝐵𝐴𝑈
𝐻𝐶𝐵𝐴𝑈× 100 [𝑢𝑛𝑖𝑡: %]
The formula is applicable for TSO with RES integration and for DSO with DER integration.
Where:
EHC % is the enhanced hosting capacity of RES/DER when R&I solutions are applied with
respect to BAU scenario.
HCR&I is the additional hosting capacity of RES/DER when R&I solutions are applied with
respect to currently connected generation (GW or MW)
HCBAU is the additional hosting capacity of RES/DER in BAU scenario applied with respect to
currently connected generation (GW or MW).
2 B.2 Reduced energy curtailment of RES and DER (DSO+TSO)
The objective of this KPI is the reduction of energy curtailment due to technical and
operational problems, such as over voltage, over frequency, local congestion, etc. In the
case of the DSO, the increased presence of monitoring will have an impact on producers, as
the time for curtailment will be reduced, and the operative range will be wider. This
indicator can be measured as the percentage of GWh electricity curtailment from DER
reduction of R&I solution compared to BAU for a period of time, i.e. a year.
𝐸𝑛𝑜𝑡−𝑖𝑛𝑗𝑒𝑐𝑡𝑒𝑑 =𝐸𝑛𝑜𝑡−𝑖𝑛𝑗𝑒𝑐𝑡𝑒𝑑
𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 − 𝐸𝑛𝑜𝑡−𝑖𝑛𝑗𝑒𝑐𝑡𝑒𝑑𝑚𝑒𝑎𝑠𝑢𝑟𝑒𝑑
𝐸𝑛𝑜𝑡−𝑖𝑛𝑗𝑒𝑐𝑡𝑒𝑑𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒
Where:
Enot-injected is the percentage reduction in energy not injected in network due to MV/LV
network conditions [MWh].
E_not-injected, baseline is the total energy not injected in network due to MV/LV network
conditions under baseline condition [MWh].
E_not-injected, measured is the total energy not injected in network due to MV/LV network
conditions under new measured condition [MWh].

3 B.3 Power Quality and Quality of Supply (DSO+TSO)
This KPI is based on the goal of maintaining high quality of power supply to end users via
preventive actions with early warning system, advanced and optimal system development
and operation tools, and high availability of assets via optimal maintenance strategies and
planning tools. For the DSO, three indicators are proposed:
a) SAIDI and SAIFI indicators:
∆𝑆𝐴𝐼𝐷𝐼% =𝑆𝐴𝐼𝐷𝐼𝑆𝐺 − 𝑆𝐴𝐼𝐷𝐼𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒
𝑆𝐴𝐼𝐷𝐼𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒× 100 [𝑢𝑛𝑖𝑡: %]
∆𝑆𝐴𝐼𝐹𝐼% =𝑆𝐴𝐼𝐹𝐼𝑆𝐺 − 𝑆𝐴𝐼𝐹𝐼𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒
𝑆𝐴𝐼𝐹𝐼𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒× 100 [𝑢𝑛𝑖𝑡: %]
Where:
SAIDI is the System Average Interruption Duration Index
SAIFI is the System Average Interruption Frequency Index
b) Line voltage profiles fulfilling grid nominal voltage requirements, as defined in EN 50160
standard [EN 50160]:
𝑉% =𝑉𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 − 𝑉𝑆𝐺
𝑉𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒× 100 [𝑢𝑛𝑖𝑡: %]
Where:
V% is the evolution of the line voltage profiles
VSG is defined as the line voltage profiles with SG solutions
Vbaseline is the line voltage profiles in baseline situation
The definition of voltage profile can vary, including different options:
- Vmax: maximum reached line voltage during defined monitoring period
- V95%: value for which 95% of all voltage line measurements fall below
- Total number of voltage line violations
c) Average time needed for awareness, localization and isolation of grid fault:
∆𝑇𝑓𝑎𝑢𝑙𝑡[%] =𝑇𝑓𝑎𝑢𝑙𝑡,𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 − 𝑇𝑓𝑎𝑢𝑙𝑡,𝑆𝐺
𝑇𝑓𝑎𝑢𝑙𝑡,𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒× 100 [𝑢𝑛𝑖𝑡: %]
Where:
∆Tfault [%] is the percentage reduction in time required for fault awareness, localization and
isolation
Tfault,SG is the average time required for fault awareness, localization and isolation with
Smart Grid Solutions
Tfault,Baseline is the average time required for fault awareness, localization and isolation in
Baseline situation

4 B.4 Extended asset lifetime (DSO+TSO)
The base of this KPI is that, thanks to R&I solutions, network assets can last longer while
maintaining the system reliability, so the replacement costs are reduced. There are two
alternatives to define this indicator:
a) Improved Life-time of Assets takes into account the total cost of exploiting a given
group of assets, including the capital expenditure and the operational expenditure:
𝐼𝐿𝐴 =(𝐶𝐴𝑃𝐸𝑋𝐵𝐴𝑈 + 𝑂𝑃𝐸𝑋𝐵𝐴𝑈) − (𝐶𝐴𝑃𝐸𝑋𝑅&𝐷 + 𝑂𝑃𝐸𝑋𝑅&𝐷)
(𝐶𝐴𝑃𝐸𝑋𝐵𝐴𝑈 + 𝑂𝑃𝐸𝑋𝐵𝐴𝑈)
b) Improved Life-time of Assets looking only at the replacement costs (RC):
𝐼𝐿𝐴 = (𝑅𝐶𝐵𝐴𝑈 − 𝑅𝐶𝑅&𝐷)/(𝐶𝐴𝑃𝐸𝑋𝐵𝐴𝑈)
Where:
CAPEX is the Capital Expenditure
OPEX is the Operational Expenditure
RC is the Replacement cost
5 B.5 Increased flexibility from energy players (DSO+TSO)
The flexibility is an indication of the ability of the electricity system to respond and balance
supply and demand in real-time. To this matter, dispatchable generation technologies help
to adjust output on demand serve.
Regarding DSO operations, power flexibility is mainly measured through
demand/generation response capabilities, so both indexes will be defined:
Demand:
𝑃𝐷𝑆𝑀 =(𝑃𝐷𝑆𝑀)𝑆𝐺 − (𝑃𝐷𝑆𝑀)𝐵𝐴𝑈
𝑃𝑝𝑒𝑎𝑘
∆𝑃𝑅𝐿% =𝑃𝐿𝑅𝑆𝐺
𝑃𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒,𝑝𝑒𝑎𝑘
Generation:
𝑃𝐷𝐸𝑅 =(𝑃𝐷𝐸𝑅)𝑆𝐺
∑ 𝑃𝑅 𝑆𝐺−
(𝑃𝐷𝐸𝑅)𝐵𝐴𝑈
∑ 𝑃𝑅 𝐵𝐴𝑈
Where
PRL is the Peak Load Reduction
PDSM represents the amount of load capacity participating in DSM in the BAU and SG
scenario
IDE4L Deliverable D7.1
18 IDE4L is a project co-funded by the European Commission
Ppeak represents the maximum electricity demand in area under evaluation
PDER represents the amount of flexible generation in the in the BAU and SG scenario
PR represents the installed capacity of each generation and/or storage unit on the system
6 B.6 Improved competitiveness of the electricity market (DSO+TSO)
R&I solutions facilitate the high penetration of DER/RES. In order to integrate these
technologies (demand-side management, energy storage ...) by improving the
competitiveness in the electricity market, efficient market mechanisms need to be put in
place, providing energy and ancillary services to the grid at affordable costs.
Three different definitions are provided:
a) Cost of a Given service:
Evaluated in N different national/regional markets:
𝐷𝐶𝑆 = ∑ (𝐶𝑆𝑖 − 𝐶𝑆𝑗)2
𝑁
𝑖,𝑗=1𝑖≠𝑗
Comparing DCS between BAU and R&D scenarios:
∆𝐷𝐶𝑆 = 𝐷𝐶𝑆𝐵𝐴𝑈 − 𝐷𝐶𝑆𝑅&𝐷 = ∑ (𝐶𝑆𝑖𝐵𝐴𝑈 − 𝐶𝑆𝑗
𝐵𝐴𝑈)2
𝑁
𝑖,𝑗=1𝑖≠𝑗
− ∑ (𝐶𝑆𝑖𝑅&𝐷 − 𝐶𝑆𝑗
𝑅&𝐷)2
𝑁
𝑖,𝑗=1𝑖≠𝑗
Where:
DCS is the difference in Cost of Service
N is the number of regional markets
b) Number of market players
∆𝑀𝑂𝑁 = ∑ 𝑀𝑂𝑖
𝑁𝑅&𝐷
𝑖=1
− ∑ 𝑀𝑂𝑖
𝑁𝐵𝐴𝑈
𝑖=1
Where:
MO is the market operator
NR&I is the number of market operators participating in a given market following
deployment of smart grid solution
NBAU is the number of market operators participating in a given market following BAU
system evolution
c) Size of individual market players
𝐻𝐻𝐼 = ∑ 𝑠𝑖2
𝑁
𝑖=1
IDE4L Deliverable D7.1
19 IDE4L is a project co-funded by the European Commission
Where:
HHI (Herfindahl-Hirschman Index or simply Herfindal Index) is a measure of the size of firms
in relation to the industry and an indicator of the amount of competition among them.
HHI is defined as the sum of the squares of the market shares (s, expressed as fraction or as
percentage) of the different firms (i = firm number i, from a total of N) within a given
industry. HHI ranges from 1/N to 1. An increase in the HHI generally indicates a decrease in
competition and an increase of market power
7 B.7 Increased hosting capacity for Electric Vehicles and other new loads (DSO)
This KPI is intended to measure the capacity of the network to host the new load that
emergent large fleets of electric vehicles (EV) represent. A proposal for this calculation is
provided:
𝐻𝐶_𝐸𝑉% =𝐻𝐶_𝐸𝑉𝑆𝐺 − 𝐻𝐶_𝐸𝑉𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒
𝐻𝐶_𝐸𝑉𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒× 100
Where:
HC_EVSG is the Hosting Capacity of Electric Vehicles in MV and LV network with Smart Grid
solutions
HC_EVbaseline is the Hosting Capacity of Electric Vehicles in MV and LV network under a
normal baseline situation (no intelligent solutions)
HC_EV% is the percentage of increase in Hosting Capacity of Electric Vehicles in MV and LV
network with Smart Grid solutions
4.4 Project KPIs (EEGI Level 3)
EEGI establishes this level to include indicators explicitly designed for specific R&I projects under
the EEGI Roadmap, in order to test the impact of the solutions implemented in the demonstration
fields. However, they are expected to be similar to level 2 EEGI KPIs, or at least to contribute to
them in any case, so the following mapping can be identified:
IDE4L Deliverable D7.1
20 IDE4L is a project co-funded by the European Commission
Figure 3 Level 3 to level 2 EEGI KPI mapping
Source: EEGI Grid+ project
However, level 3 KPIs are out of the scope of GRID+ project, so no specific directions are defined.
The calculation methodology of level 2 KPIs can be used as an assessment to a possible calculation
methodology for level 3 KPIs.
4.5 EEGI Framework contextualization for IDE4L: IDE4L methodology
Once this EEGI framework is analysed, it must be adapted to IDE4L requirements and needs. The
way to proceed is to define different KPIs for each Use Case, focused on measuring the
improvement that they provide to the system: these are EEGI level 3 KPIs. Once these KPIs are
selected and defined, their contribution to EEGI level 2 KPIs will be analysed. Overarching KPIs are
not considered, due to their relation with clusters of projects.
In order to define IDE4L KPIs properly, a methodology has been defined. It consists of six main
steps:
1. Use Case Definition
In order to start defining the Project Key Performance Indicators, a detailed definition of the
Use Cases must be provided.
2. KPI proposal (general definition)
3. Agreement among WP leaders
A general template will be provided for a first approximation to the KPI list. This list will be
reviewed by project partners until a definitive list of KPIs is achieved.
4. Specific KPI definition, scenario identification, required data and step-by-step procedure
A complete template should be filled out for each one of the KPIs, following these main
sections:
• General and specific description of the magnitude to be measured
IDE4L Deliverable D7.1
21 IDE4L is a project co-funded by the European Commission
• Main objective
• Connection with other KPIs and Use Cases
• Magnitude formula
• Formula of the KPI as a difference (improvement or worsening) between scenarios
• Step-by-step methodology for the evaluation
• Required data and granularity
• Definition of scenarios (Baseline, BaU, Smart Grid) where the magnitude must be
measured
5. Data Collection
Depending on the type of data required and the frequency of data acquisition, proper
templates will be prepared in order to collect the information needed to calculate the KPI.
6. KPI Calculation
KPI is calculated using a data compilation tool, e.g., an Excel file. The evaluations will include
the calculation of the magnitude in the specific scenarios, and their comparison using the KPI
formula.
This procedure can be summarized in the following diagram:
Figure 4 KPI definition, selection and calculation procedure
In order to select and define these KPIs, two templates have been created:

5. KPIS AND USE CASES CORRESPONDANCE
In order to define IDE4L KPIs, an analysis of each Use Case is performed, so that the parameters
necessary to evaluate the Use Case are determined. Hence, the chosen methodology is the
definition of a set of KPIs for each Use Case. This assignation is shown in the following table:

GENERAL COMMENTS
This KPI provides a performance index for state estimation accuracy. Demonstration laboratory: - The estimated states are compared with actual network states read directly from RSCAD/RTDS. - Provides a much more comprehensive view on state estimation accuracy than the field demonstrations since true values for all variables can be read from the simulator.
IDE4L Deliverable D7.1
43 IDE4L is a project co-funded by the European Commission
- The LVSE KPI will be calculated with the highest possible frequency (e.g. once every 10 seconds) so that even the effects that temporary fluctuations in electricity consumption have on LV network state are taken into account. Field demonstrations: - Some of the real-time measurements are reserved for KPI calculation and only a part of real-time measurements are used as inputs to the LVSE. At the moment (2014), the DNOs participating to this project do not have LV network state estimation capabilities. Also, in general, calculation of LV network state estimates does not belong to current DNO practices. Therefore, the KPI’s for business-as-usual scenarios are not calculated. However, comparisons with different measurement setups are made. In addition to the above defined KPI, another important performance metric for LV network state estimation is the state estimation function execution time which is measured separately.

Details of Baseline
Distribution network calculation software and practices vary from country to country and utility to utility. Therefore it is impossible to define one universal baseline case for state estimation. Some network management programs are capable of calculating MV network state estimates. The DNOs participating in field demonstrations do not have (yet) this possibility and therefore baseline performance indices are not calculated for MV network state estimation.

6.3 UC3: Dynamic Monitoring for TSO Two KPIs are defined to evaluate this Use Case:
Voltage stability of the electricity system (I)
BASIC KPI INFORMATION
KPI Name Voltage stability of the electricity system KPI ID I
Main Objective This KPI measures improvement in TSO’s awareness of voltage stability issues in their downstream distribution grids.
KPI Description
This KPI measures improvement achieved in IDE4L project in TSO’s awareness of voltage instabilities occurring in its downstream distribution systems.
The KPI can be evaluated by comparing a stability index, calculated for the distribution feeder based on the distribution system conventional data at TSO, with a similarly defined stability index, calculated based on real-time measurements and equivalent models of the distribution system at DSO.
KPI Formula
∆𝐼[%] = |𝐼𝑟𝑡−𝐼𝑜𝑓𝑓
𝐼𝑜𝑓𝑓| × 100
Where Irt is the stability index calculated based on real-time measurements and equivalent models of the distribution system at DSO, and Ioff is the stability index calculated based on distribution system conventional data at TSO.
The stability index (I) itself has to be defined during the project.

Success index in meter reading (SIMR)
BASIC KPI INFORMATION
KPI Name Success index in meter reading KPI ID SIMR
Main Objective Evaluation of the impact of low-cost power converters to the performance of PLC-based communications for metering applications in LV distribution networks
KPI Description
(Primary Use Case: PLC communications for the active distribution grid) This KPI evaluates the impact of different degrees of penetration for low-cost power converters applied mainly in the integration of renewable generation in the distribution grid, on the correct reception of PLC data packets for metering purposes.
KPI Formula 𝑃𝑎𝑐𝑘𝑒𝑡 𝐸𝑟𝑟𝑜𝑟 𝑅𝑎𝑡𝑒 (𝑃𝐸𝑅) can be defined according to:
IDE4L Deliverable D7.1
51 IDE4L is a project co-funded by the European Commission
𝑃𝐸𝑅 =𝑎𝑚𝑜𝑢𝑛𝑡 𝑜𝑓 𝑖𝑛𝑐𝑜𝑟𝑟𝑒𝑐𝑡𝑙𝑦 𝑟𝑒𝑐𝑒𝑖𝑣𝑒𝑑 𝑑𝑎𝑡𝑎 𝑝𝑎𝑐𝑘𝑒𝑡𝑠 𝑖𝑛 ′Δ𝑡′
𝑡𝑜𝑡𝑎𝑙 𝑎𝑚𝑜𝑢𝑛𝑡 𝑜𝑓 𝑡𝑟𝑎𝑛𝑠𝑚𝑖𝑡𝑡𝑒𝑑 𝑑𝑎𝑡𝑎 𝑝𝑎𝑐𝑘𝑒𝑡𝑠 𝑖𝑛 ′Δ𝑡′
So it will be evaluated by considering:
1. Number of packets that are being sent by the transmitter during a time interval ‘Δt’.
2. Number of packets that are being received during the same time interval ‘Δt’, and
3. The ones that are being received incorrectly The evaluation of this KPI is performed previously calculating the packet error rate (PER) of the communication between the PLC transmitter and receiver, according to the expression:
𝑆𝐼𝑀𝑅𝑡 =𝑃𝐸𝑅𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 − 𝑃𝐸𝑅𝐵𝑎𝑈
𝑃𝐸𝑅𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒
Where: 𝑆𝐼𝑀𝑅𝑡 is the success index in meter reading during a given period 𝑡 𝑃𝐸𝑅𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 is the packet error rate in the baseline scenario 𝑃𝐸𝑅𝐵𝑎𝑈 is the packet error rate in the business as usual scenario

GENERAL COMMENTS
Two scenarios are taken into consideration. In the baseline scenario, a low degree of renewable penetration in LV networks is considered -thus with low penetration of low-cost power converters-, whereas in the BaU scenario a higher degree of renewable penetration is assumed, considering that no innovations are implemented to assure sufficient frequency of meter readings. There will be a demonstration in IREC laboratory facilities, where an experimental set-up with both the power (converter, line impedances, load) and the PLC-based communications infrastructures (PLC transmitter, PLC receiver...) will be used at lab scale to measure the frequency of meter readings in both scenarios.
6.6 UC6: MV&LV Load Forecast Two KPIs have been defined in this case:
LV Load/generation forecaster (LVLGF)
BASIC KPI INFORMATION
KPI Name LV Load/Generation Forecaster KPI ID LVLGF
Main Objective Evaluate the accuracy of the load/generation forecasts for the predefined prediction horizons on the LV network.
KPI Description
The KPI evaluates the deviation between the forecasted values and the corresponding measurements for the load/generation when becoming available. This is a measure for the reliability of the applied forecasting method as a function of the considered forecast horizons. This provides an error measure for the variance of the considered load/generation prediction horizons in the field

GENERAL COMMENTS
The aim is to evaluate the prediction error for the prediction horizons that are considered in the IDE4L field tests. With such an approach the reliability of the load/generation forecast method can be verified for subsequent actions depending on the forecast outputs. However, the KPI should be initially applied to a case in a demonstration laboratory, to construct references for the KPI’s applied to the field demonstration.
MV Load/generation forecaster (MVLGF)
BASIC KPI INFORMATION
KPI Name MV Load/Generation Forecaster KPI ID MVLGF
Main Objective Evaluate the accuracy of the load/generation forecasts for the predefined prediction horizons on the MV network.
KPI Description
The KPI evaluates the deviation between the forecasted values and the corresponding measurements for the load/generation when becoming available. This is a measure for the reliability of the applied forecasting method as a function of the considered forecast horizons. This provides an error measure for the variance of the considered load/generation prediction horizons in the field test, for the particular load/generation in node. This indicates that the large prediction errors have the largest effect in the evaluation.

where:
𝑘 : look-ahead time

The LV network state estimator (LVSE) calculates the corresponding state estimates 𝑥(𝑡 + 𝑘) for the LV network (this happens k hours after the step LVSF-1).

GENERAL COMMENTS
This KPI provides a performance index for state forecasting accuracy. The performance index is calculated as a function of look-ahead time. The forecasted states are compared with estimated states instead of actual measured states. This is because in field demonstrations all states are not measured and measurement data can contain errors. Measurement errors are detected and filtered during the state estimation process. Therefore, the estimated state values are the best possible estimates we have on our disposal. During laboratory demonstration it would also be possible to use real measured values but then the LVSF’s would not be comparable with LVSF’s calculated during field demonstrations. LVSF can be calculated for single (N=1) or multiple (N>1) state variables and for different types of state variables. During IDE4L project, LVSF will be calculated for the following cases with multiple state variables:
1) customer connection point voltages 2) customer connection point power flows 3) line currents (all lines within LV network).
Three cases with different types of variables are calculated because the results of LVSF are utilized for a variety of purposes, and although these variables are interconnected, separate accuracy indices for different variables help us to evaluate the effect of forecasting errors on specific control functions (e.g. voltage control). LVSFs for individual state variables will be calculated only if a special need to study them arises during simulations or demonstrations. The forecasting horizon can be as long as 48 hours and is divided into time intervals of unequal length. For the first couple of hours the forecasts are made with high resolution (e.g. 10 minutes) but after that the forecasts are made on an hourly basis. The state estimation is run several times during one hour (e.g. once a minute). Therefore, average values over the forecasting window (e.g. 10 min or 1 h) must be calculated so that the state estimates can be compared with the state forecasts. Distribution network calculation software and practices vary from country to country and utility to utility.
IDE4L Deliverable D7.1
58 IDE4L is a project co-funded by the European Commission
Therefore it is impossible to define one universal business-as-usual case for state forecasting. To our knowledge there is no automatic state forecasting in existing network calculation or management software. However, Finnish DNOs for example have possibility to initiate manually LV network load flow calculation for any given hour in the future. This calculation utilises customer class load profiles. This could be considered as rudimental state forecasting. The DNOs participating in field demonstrations do not have this possibility and therefore the baseline and business-as-usual performance indices are not calculated for LV state forecasting. In addition to the above defined LVSF index, another important performance metric for LV network state forecasting is the state forecasting function execution time which is measured separately.

Network Description Update (NDU)
BASIC KPI INFORMATION
KPI Name Network Description Update KPI ID NDU
IDE4L Deliverable D7.1
61 IDE4L is a project co-funded by the European Commission
Main Objective Evaluation of the percentage of the grid which can be actually managed by using WP5-like algorithms
KPI Description
Assuming that there isn’t any tool to align the central database which contains overall description of the network and the distributed DBs located in PSs and SSs. Each change in the network (new customer connected, changing of cables, new substation, new PV, etc.) implies that an entire area cannot be managed by WP5-like algorithms (State Estimation, Power Flow Control, etc.) which rely on the accurate description of the network topology. Summing the average number of changes per year per type, we can estimate the percentage of the grid which can be actually managed by IDE4L features.
KPI Formula
This KPI is evaluated by using historical data about changes on the network description.
As an example, the impact due to changes related to new customers in one year can be determined in the following way:
𝑵𝑫𝑼 =𝒁

Where:
Z: Average number of feeders which have new customers in one year

GENERAL COMMENTS
Control schemes used in tests: 1. Base case: No control. 2. Non-market case: Tertiary control without market integration (directly controlled DER only). In this
case, DER is either owned by DSO or under a bilateral contract that allows the DSO to control it directly.
3. Market case: Tertiary control with market integration (dynamic grid tariff, indirectly controlled DER).
Test setup:
Network reconfiguration: Tertiary controller uses network reconfiguration algorithm to find the optimal configuration for the MV network.
Network reconfiguration with directly controlled DER: Tertiary controller uses network reconfiguration algorithm to find the optimal configuration for the MV network and then applies power limits and voltage references to the secondary controllers (MVPC/LVPC).
Dynamic tariff: Tertiary controller applies a dynamic grid tariff to avoid network congestion. This test setup goes together with DADT KPI, where the setup is described in more detail.
DSO asking to buy flexibility services in the market The 4 parameters described before are calculated for the purpose of comparing results of the different test
sequences.

Control schemes used in tests:
– Base case; no control
– Primary control schemes:
a. Single type of controllers: AVC control, AQR control, AVR control, AVR control with a deadband
b. Combination of two independent primary controllers: AVC and AQR, AVC and AVR, AVC and AVR
with a deadband
– Secondary control schemes
a. CVC control with AQR
b. CVC control with AVR
Controllers:
1. Automatic Voltage Controller (AVC) of the OLTC
2. Automatic Voltage Regulator (AVR) of the DER unit
3. Automatic Reactive power Regulator (AQR) of the DER unit
4. Production curtailment of the DER unit
5. Direct load control (load shedding) of the DER unit
IDE4L Deliverable D7.1
83 IDE4L is a project co-funded by the European Commission
Test setup:
AVC control: The AVC control is realized using an AVC-relay connected to the substation transformer,
which maintains the constant secondary voltage of transformer as close to the reference value as
possible.
AQR control: DER units control the power factor (or reactive power) of their connection points.
AVR control: DER units control the voltage of their connection points.
AVR control with a deadband: AVR control with a deadband the PID controller only changes reactive
power generation or consumption when the connection point voltage is outside of the allowed range
of voltage.
AVC control and AVR control: Combination of two control schemes.
AVC control and AVR control with a deadband: Combination of two control schemes. AVC relay
controlling the OLTC has a deadband to prevent changes of tap position unless the voltage differs
enough from the reference value.
CVC control with AQR: Secondary controller (OPF algorithm) controls the reference values of AVC and
DERs (reactive and real power).
CVC control with AVR: Similarly like previous control scheme, except that AVRs of DER units are
operated in voltage control mode during the delay of OLTC when it is activated by the secondary
controller and for a safety period after the tap change. During this time period the secondary
controller provides the voltage reference for AVR instead of reactive power reference.
The 4 parameters described before are calculated for the purpose of comparing results of the different test
sequences.

KPI Description
This KPI looks at a set of technical safety parameters relating to the MV network

quantify the benefits of the MVPC in a period of time. The voltage/current safety
parameters are as follows:

using trapezoidal integration. These volumes are formed between the
maximum voltage plane and the network voltage profile in a three
dimensional coordinate system. In this system x-axis is the node
IDE4L Deliverable D7.1
90 IDE4L is a project co-funded by the European Commission
numbering, y-axis is the time (s) and z-axis is the node voltage (pu), which
means that the unit of the volume is (pu*s).
2) Over-current volume [pu * s]: The over-current volumes are calculated
using trapezoidal integration. These volumes are formed between the
maximum currents and the network currents in a three dimensional
coordinate system. In this system x-axis is the branch numbering, y-axis is
the time (s) and z-axis is the branch current (pu), which means that the
unit of the volume is (pu*s).
3) Under-voltage volume [pu * s]: This is calculated similarly than over-
voltage volume from minimum voltage plane and the voltage profile.
4) Duration the voltage/current is out of bounds [s]: It is the duration when
voltage/current exceeds allowed range.

GENERAL COMMENTS
This KPI has been defined for UC “Decentralized FLISR”
Interconnection switch (IS)
BASIC KPI INFORMATION
KPI Name Interconnection Switch KPI ID IS
Main Objective This KPI evaluates the performance of the interconnection switch
KPI Description It measures the capability of the Interconnection Switch of isolating a microgrid under different contingencies in the distribution grid.
KPI Formula
KPI = 1/(1 + ct/α + rt/β), the higher the better. (KPI = 1 ideal behavior)
Where ct (Clearing Time) is the time from fault occurrence to microgrid isolation in milliseconds and α is the typical closing time (α = 50); rt (Reconnection Time) is the time from reconnection trigger signal to reconnection, in milliseconds, and β is the typical reconnection time (β = 5000). Notice that reconnection trigger may be issued by FLISR or DSO and send to the microgrid central controller, which is responsible to synchronize the microgrid with the distribution grid. Thus the performance of rt no only depends on the IS, but also on the microgrid implementation as well. For this reason, ct has more weight in the KPI formula.
The proposed KPI formula reflects that the complexity to obtain high values of KPI is non-linear with respect to ct and rt; i.e., the slope of the KPI function is much higher from 0 to 50 ms, than from 100 to 150. This is because with the ”classical” technology (mechanical switch), is easy to get ct around 100 ms. However, to obtain ct lower than 50 ms, newer technology, such as static switch, would be required. See Figure 1 for typical values of KPI depending on ct and rt.

GENERAL COMMENTS
Good performance is indicated by a KPI bigger than 0.3 (i.e. ct is at least faster than 125ms). KPI values below 0.2 might not be acceptable. The rt parameter should be repeatedly measured, as its value will depend on the initial phase difference between the microgrid and the distribution grid voltage. The lowest value should be taken, since we are evaluating the IS performance, not the microgrid synchronization algorithm.
6.14 UC14: Power quality control One KPI is defined to evaluate this Use Case:
Flicker mitigation MV/LV active grid (Flick_M)
BASIC KPI INFORMATION
KPI Name Flicker mitigation in MV/LV lines KPI ID Flick_M
Main Objective This KPI evaluates the performance of some sort of variable DER units connected to the distribution power grid (wind, PV), that can cause some disturbance in the power quality signal such as flicker noise.
KPI Description
It measures the capability of improving power quality at certain points of medium voltage / low voltage electrical networks for protection of the connected loads and / or other equipment or installations. Power quality is a generic term concerning several aspects affecting the constancy and waveforms of current and voltage in the electrical systems. Power quality can be affected, for instance, by the stochastic nature of the power flows in networks with high penetration of renewable generators, which are connected to the network through power electronics. This KPI addresses a specific aspect of power quality as named in the following:
- Voltage flicker levels.
KPI Formula
Flicker is a subjective sensation of visual instability provoked by fast fluctuations in light stimulus. It can cause annoying luminance changes in lamps in the frequency spectrum from 0.05 Hz to 35 Hz. According to experimental analyses, flicker sensation is maximum at 8.8 Hz and it depends on two major variables: the square of the magnitude of voltage fluctuations and the time length of these disturbances. Flicker emission severity can be calculated according to the international
IDE4L Deliverable D7.1
100 IDE4L is a project co-funded by the European Commission
standard IEC 61000-4-15. This standard describes the so-called flicker meter. This device provides two flicker indices: short and long term flicker severity, from the measurement and processing of voltage signal at the required connection point. Also, it can provide a third index, the instantaneous flicker sensation. This instantaneous flicker index is intended to represent the instantaneous sensation experienced by humans while subjected to a fluctuating light stimulus. Short-term flicker severity index requires precise measurement of RMS voltage level for at least 10 minutes, while continuous measurement of voltage for up to 2 hours is needed for determining long-term flicker index. According to IEC 61000-4-15, the flicker meter is composed by the 5 major modules represented in the following figure.
Figure 8, Flicker meter representation
As shown, the determination of the instantaneous flicker severity index, 𝑃𝑖𝑛𝑠𝑡(𝑡), is required to compute both short-term and long-term indices (𝑃𝑠𝑡(𝑡) and 𝑃𝑙𝑡(𝑡) respectively). In order to compute 𝑃𝑖𝑛𝑠𝑡(𝑡), first voltage measurement has to be scaled to a 230 V RMS signal in Module 1, then the square of this signal is obtained in Module 2 and all serve to represent the equivalent voltage fluctuation of a domestic lamp. The obtained signal at this point is double-filtered in Module 3 to obtain the instantaneous sensation of flicker just prior being processed by the brain. To this aim, Module 3 firstly applies a first-order Butterworth high-pass filter with cut-off frequency 0.05 Hz. Then, the resultant signal is further modified by a high-pass filter (sixth order, Butterworth type, with a cut-off frequency 35 Hz, thus bounding at this frequency voltage fluctuations associated to flicker). Finally, Module 3 applies a third transfer function in order to emulate the response or the effect of voltage fluctuations of a domestic lamp in human eyes. All these filters and transfer functions serves to obtain a fluctuating signal which is further processed and low-pass filtered in Module 4 of flickermeter, emulating the instantaneous response of human brain to such fluctuating light stimulus, so giving the instantaneous sensation of flicker index 𝑃𝑖𝑛𝑠𝑡(𝑡). As previously noted, the instantaneous flicker index serves to compute 𝑃𝑠𝑡(𝑡) and 𝑃𝑙𝑡(𝑡) and these are calculated applying statistic treatment to 𝑃𝑖𝑛𝑠𝑡(𝑡). Detailed description around these statistics will be offered when convenient. To sum up, and for the sake of clarity, the mathematical expressions for 𝑃𝑠𝑡(𝑡) is calculated as
𝑃𝑠𝑡(𝑡) = √0.314𝑃0.1 + 0.0525𝑃1𝑠 + 0.0657𝑃3𝑠 + 0.28𝑃10𝑠 + 0.08𝑃50𝑠,

From a sequence of short-term flicker indexes (the last 12 indexes determined each 10 minutes), it is easy to compute the long-term flicker index by

The flickermeter is the standardized device to measure flicker noise and as such should be properly implemented in the active flicker filter to be developed in this use case, for addressing power quality in electrical networks. The comparison between the previously described indexes provided by the flickermeter prior and after the implementation of the active flicker filter determines the KPI to evaluate the performance of the designed solution.

GENERAL COMMENTS
The network expansion planning consists of defining possible development steps and then defining the best sequence of steps in order to reach the predefined target network (illustrated on figure 9). The purpose of this KPI is to help planners in decision making when selecting the development sequence.

Possible developement steps
One possible developement scenario
Figure 9: Expansion planning
Assumptions of calculations:
Temporal information from city planning is available.
DER scenario provides information about changes of loads and production in general.
Planning will consider only MV network. HV network is assumed to be ideal. Primary and secondary
substation sitting is not considered i.e. substations are located in given places. LV customers are
divided between neighboring secondary substations based on “electrical distance” principle.
o LV feeders are not modeled. Distribution transformer is included in the model.
o Aggregated loads (statistical sum of load profiles) and production (time series of DG unit
types, correlation within DG unit type is one)
o Replacement costs are considered (aging of network (possible maximum service lifetime) or
component rating).
o Protection requirements (short-circuit current) determine the size of cables and over-
loading of cables is not possible with hourly average values. Therefore congestion
management is needed only for a secondary transformer.
Outage costs:
o Fictive cost utilized in network regulation (profit regulation) to optimize network
investment cost and inconvenience caused by outage from societal viewpoint.
Variable cost component dependent on outage duration: very short < 1s and short
< 3 min (low value) and long (high value)
o Direct cost of energy not supplied only for faults of long duration.
IDE4L Deliverable D7.1
109 IDE4L is a project co-funded by the European Commission
Assumptions of reliability analysis:
o Substation and HV network failures are not considered.
o Failure rate of MV line is dependent on type of line (cable, covered conductor overhead line
or bare overhead line) and terrain of overhead line (field, beside a road or in forest).
o Failure rate of components is dependent on age of component after nominal lifetime (<
possible maximum service lifetime).
o Outage duration: switching time (automation functionality (fast < 1s, slow < 3 min, very
slow ASAP) and type of switches), repair time of permanent faults (statistical variable), and
number of simultaneous faults.
o Island operation is not considered.
Investment costs:
o Electrical component costs are fixed. They don’t change over time.
o Investment has an initial cost. For example if two investments from the same area may be
combined together, they have also a single initial cost.
o Rates of inflation, interest, etc. are constants.
Parameters of automation/ICT: Initial cost, operational cost (maintenance/service cost), size of
system, and number of actions (amount of data). Three scenarios for automation/ICT: i) DSO owns
and operates everything, ii) DSO owns controls of DER but purchase communication services, and
iii) DSO purchase only services.
Costs of active controls:
o Direct control of DSO’s resources has fixed value based on average maintenance cost of
resource.
o Direct control of DERs has fixed compensation per action (e.g. €/kWh/h) and annual
compensation (compensation may have different value for each DER)
o Indirect control has variable compensation per action based on day-ahead market price.
Energy consumed by network losses:
o The cost of losses is the average of day-ahead market price over several years.
o The cost itself may be part of DSO planning optimization or not (depending who is paying
losses in national regulation model).
Modeling of operational decisions is simplified:
o Energy management of day-ahead market does not include forecasting of price, load or
production (price, load and generation has a given scenario), bidding strategies, etc. The
demand response of DERs is based on cost optimization of energy price (consumed and
produced) and variable grid tariff (consumed and produced).
o Intra-hour behavior of DERs is not considered.
o Availabilities of DERs, communication, active controls, etc. are based on normal behavior,
i.e. failures of them are not considered. Alternative scenario may consider different kind of
availabilities.
The progress of following network performance variables are considered through the planning horizon:
Network capacity
- loading and hosting
Reliability
IDE4L Deliverable D7.1
110 IDE4L is a project co-funded by the European Commission
- indexes (SAIDI, SAIFI, …)

Maintenance cost
- The age of network components impact on maintenance cost.
Investment costs
- Costs of transition from one development step to another
Usage of active control methods (DR, AVC, Congestion management, …)
- Cost of usage (production curtailment, ancillary services, …)
The KPI shall indicate if a strategy of using active network management functionalities would lead to lower total expenses for DSO over the planning horizon than a strategy of using passive reinforcement methods.

GENERAL COMMENTS
The KPI will determine which strategy is the best for the consumers under given regulatory assumptions (role of the aggregator, energy market architecture) and different price levels. The aggregator will have the role also of retailer and will coordinate inflexible and flexible demand, RES and other generation resources, as well as storage devices. The price levels will be taken from existing markets, but they will also be modified to take into account different price patterns that will arise if the future implementation of smart grids flattens the demand curve shape. The regulatory framework will be assumed as flexible and designed to allow taking advantage of all the technical possibilities offered by existing and envisaged smart grid technology.

GENERAL COMMENTS
The use of scheduling strategies leads to the flattening of load curve, enabling a better utilisation of grid elements. This is possible thanks to optimized schedules that increase the consumption in the valley hours and reduce it in the peak hours. The reduction of this ratio leads to a better use of grid components. Different conditions, such as electrical heating, weather conditions, shares of industrial and domestic load will be taken into account, if there are data available. This KPI has been proposed by the EC Task Force for Smart Grids (KPI no. 21). [Giordano]

7. GUIDELINES FOR KPI EVALUATION
7.1 Introduction to the methodology
This chapter is intended to give a detailed picture of the KPI evaluation methodology,
indicating the process to be followed depending on the type of KPI to be calculated. IDE4L
KPIs are not only practical, but also theoretical, so the EEGI methodology has to be modified
to cover these different alternatives.
7.2 IDE4L to EEGI KPIs mapping
The main aim of IDE4L automation architecture is the improvement of the distribution
network business, reducing costs and future investments to manage the grid. This goal is
achieved by means of efficiency measures supported by ICT instruments, which involve
planning processes, considering DERs and REs, fault location isolation and restoration and, in
general, all the processes involved in network management and control. The functional units
developed in the architecture and identified in the project Use Cases have this business
improvement as basic and general characteristic. However, some of these units have been
defined to enable functionalities provided in other units and, for this reason, they have no
direct improvements on the network management. For example, the monitoring Use Cases
do not provide a direct enhancement on the network business but they allow the execution
of other algorithms, such as the state estimation or the optimal power flow, which allow
improving the grid management and planning processes.
Figure 10: Mapping Schema for IDE4L KPIs and EEGI Level 2 KPIs
Taking into account these considerations, it is easy to understand that some of the IDE4L
KPIs, those defined to evaluate Use Cases related to the general smart grid business, can be
mapped to EEGI Level 2 KPIs – Table 1 –. In contrast, some others match no EEGI definition,
because they are related to functionalities internal to the IDE4L architecture.

7.3 Step-by-step approach for KPI evaluation
As it has been defined in previous chapters, there are two types of KPIs:
- Measured KPIs: based on the empirical results obtained from the tests carried out in
demo sites or laboratories, and
- Theoretical KPIs: based on calculations and simulations
Given this fact, there would be two different procedures to face IDE4L KPI evaluation.
Measured KPIs
Step 1. The scenario must be determined and defined. Also, the parameter that will
characterize the Use Case validation must be analyzed and the needed data have to be
clearly selected.
Step 2. The measurements for the selected reference scenario must be collected. If baseline
scenario is chosen, the measurements must have been collected before the test cases, or
historical data must be provided. In case that not all the measurements are available, a state
estimator algorithm can be used to get all the values. If BaU scenario is the reference, these
BaU values related to the future must be calculated.
Step 3. The measurements for the smart scenario must be collected at the end of the test
cases. Just in case, a state estimator algorithm can be used to get all the values.
Step 4. The KPI is the comparison between values obtained in steps 2 and 3.

Step 5. The result must be analysed and well explained.
Theoretical KPIs
Step 1. The scenarios must be determined and defined. Also, the parameter that will
characterize the Use Case validation must be analyzed and the needed data have to be
clearly selected.
Step 2. The values for the selected reference scenario (baseline or BaU) must be calculated
from simulations or theoretical calculations.
Step 3. The measurements for the smart scenario must be calculated from simulations or
theoretical calculations.
Step 4. The KPI is the comparison between values obtained in steps 2 and 3.
Step 5. The result must be analysed and well explained.
7.4 Results template description
The numerical results of the evaluation of each KPI, as well as test conditions and conclusions
will be collected in a result template form.
The result of each KPI will be a numerical comparison of a particular feature of the use case
evaluated in two different scenarios.
To obtain these results, three different types of method can be applied:
- Based on demo measurements: Preferably, this type of method will be applied as
it will provide more accurate and realistic results.
It will be necessary to analyse if for the specific KPI to be evaluated and the demo
deployed for the particular Use Case, tools and/or measurement equipment can be
applied to determine the value of the KPI under certain operation conditions that
will be recreate on the demo site. Both operation conditions and the mechanisms
used to determine the value of the KPI will be introduced in the form under the
field “KPI Conditions Where Calculated” and “Evaluation”, respectively.
- Based on historical data: In case specific demo measurements cannot be obtained,
due to demo constraints, and historic data are available in the operation conditions
defined to obtain the KPIs, these could be used to determine the KPI in a particular
scenario.
This type of methods could be applied only for Baseline Scenarios, so it is important
to highlight that, in order to compare values with other scenarios; the same
conditions have to be considered. For instance, in case of KPI related to FLISR Use
Case, Fault Conditions has to be considered in the same points of the grid for both
scenarios.
- Based on theoretical computations: This type of method will be applied only when
none of the methods above can be used. They are based on the use of technical
data and mathematical equations for particular operation configurations of the

scenario under study. The result template should collect the relations and
explanations of the applied equations to obtain the KPI values.
For each scenario and each KPI may be applied different class of method depending of the
demo conditions and available tools. For this reason, in case of using different methods, the
result template should include a justification that values obtained with both methods are
equivalent.
In case none of the methods can be applied, KPI will be considered as not evaluable.
Figure 11 shows the steps and verifications explained above for methods selection and KPI
evaluation:

Figure 12 shows the result template form to be completed for each KPI. The type of method
applied for each scenario will be indicated in the field “Evaluation and Interpretation”.
