Abstract: This paper presents a hybrid Local Unimodal Sampling (LUS)-Teaching Learning Based Optimization (TLBO) optimized Proportional-Derivative-fuzzy-Proportional-Integral-Derivative (PD-FPID) cascaded controller to study the load frequency control (LFC) issue in a three area interconnected thermal power system considering generation rate constraint (GRC). Initially hybrid LUS-TLBO optimized conventional PD-PID cascaded controller is used and the result acquired is matched with that of Bat Algorithm optimized conventional PD-PID cascaded controller. It is proved that the proposed LUS-TLBO based PD- PID cascaded controller is revealing better dynamic performance in all aspects i.e. in terms of settling time, undershoot and overshoot. Then the study is extended to inspect dynamic behaviour of the same power system employing a novel PD-FPID cascaded controller optimized by the proposed hybrid LUS-TLBO algorithm. It is again proved that the proposed LUS-TLBO optimized PD-FPID cascaded controller is performing better as compared to LUS-TLBO based conventional PD-PID cascaded controller. A step load disturbance of 1% is applied in area1 and integral time absolute error (ITAE) is chosen as objection function in designing the proposed controller. Again sensitivity analysis of the proposed PD-FPID cascaded controller is conducted by varying the system parameters and it is seen that the proposed cascaded controller is less sensitive to parametric variations, and therefore there is no need to reset the controller parameters for wide deviation in system parameters.

Introduction: Stability and reliability of power systems significantly depends upon the deviation of frequency from its nominal value. Severity of this problem is more prominent in interconnected power system. Maintaining the frequency at its nominal value under adverse situation has been a challenging task for researchers/design engineers. Frequency deviation and exchange of tie-line power are two major issues in LFC problem. The main function of LFC is to maintain nominal frequency and to keep tie-line power exchanges as per schedule by taking into account the power generation at maximum economic level [1]. LFC issue in interconnected power system was first introduced by Elgard and Fosha [2]. LFC in single area with multi-source generation is proposed by Singh et al. [3]. In [4] for a single isolated hydro-generator system the transient speed response is discussed. Kam and Kocaarslan [5] have stated the use of fuzzy implementation for gain scheduling of conventional PI controllers. In [6] a robust PID controller is employed for LFC of a two area hydro power system. Sahu et al. [7] have proposed a DE optimized two degrees freedom PID controller for LFC of a two area thermal system taking governor deadband nonlinearity in to account. Farahani et al. [8] have employed lozi map-based chaotic algorithm (LCOA) based PID controller for LFC of a two area thermal system. S. R. Khuntia & S. Panda [9] have implemented an artificial neural network fuzzy interface system (ANFIS) based controller for LFC of a three unequal area hydrothermal interconnected system in order to obtain a suitable dynamic response. In [10], controller designed through polar fuzzy logic (PFC) is employed to reduce the computational burden and memory requirements. The projected controller is employed to study the transient study of a three area power systems and evidenced to be superior as compared to PI controller. Further they extended their work by making the PFC adaptive using genetic algorithm optimization technique and finally claimed the superiority of the adaptive PFC-GAF. Panda et al. [11] have reported the application of hybrid bacteria foraging optimization algorithm and particle swarm optimization (hBFOAPSO) technique based PI controller for LFC of a two area interconnected thermal power system. Then they extended the use of the above PI controller to study the dynamic performance of LFC for a three area interconnected hydrothermal system. Genetic algorithm (GA) and PSO based fuzzy logic controller for a three area thermal-hydro interconnected power system are proposed by Sinha et al. [12]. A novel fuzzy PI controller based on tabu search algorithm for LFC of interconnected power system is presented in [13]. To reduce and stabilize the frequency oscillation in a two area interconnected thermal power system, fuzzy logic based superconducting magnetic energy storage (SMES) units are used by Hemeida [14]. A fast acting adaptive LFC based on GA-fuzzy approach for interconnected multi-thermal power system is proposed by Ghoshal in [15]. For LFC in restructured power system, a multi-stage fuzzy-PID controller is implemented by Shayeghi et al. [16]. C. S. Indulkar & B. Raj [17] acclaimed fuzzy controller based for AGC study in a two area power system and the result found is compared with that of integral controller. Chang & Fu [18] introduced a PI controller based on fuzzy gain scheduling for LFC of a four area power system considering GRC and control deadbands.

CORPORATE REPORT

NO: R181 COUNCIL DATE: September 11, 2017

REGULAR COUNCIL

TO: Mayor & Council DATE: August 28, 2017

FROM: City Clerk FILE: 1970-04

SUBJECT: Proposed 2018 Permissive Property Tax Exemptions for Heritage Properties

RECOMMENDATION

The Legislative Services Division recommend that Council:

1. receive this report as information; and

2. authorize the City Clerk to bring forward "Section 225 Tax Exemption Bylaw, 2017,No. 19349" (the “Bylaw”) for the required readings.

INTENT

The purpose of this report is to request that Council consider permissive tax exemptions for Heritage Properties pursuant to Section 225 of the Community Charter, S.B.C. 2003, Chap. 26 and in accordance with the City's Tax Exemption Policy.

BACKGROUND

The permissive property tax exemptions included in the subject Bylaw are for heritage properties that fall within the scope of Section 225 of the Community Charter S.B.C. 2003, Chap. 26 and which generally receive a full property tax exemption. There are a few exceptions where the recommended exemption is for a portion of the respective property. In these cases, the partial exemption relates to there being a "non-heritage" addition and/or alteration on the property.

The Community Charter stipulates that exemptions under Section 225 may only come into effect for any taxation year once notice of the proposed Bylaw has been given and subject to the Bylaw being adopted by no later than October 31 of the year prior to the taxation year to which the Bylaw relates and by an affirmative vote of at least 2/3 of Council members. Public notice must be given in accordance with the Community Charter following third reading of the Bylaw.

DISCUSSION Council adopted "Heritage Property Standards of Maintenance Bylaw, 2017, No. 18931" (the “Heritage Bylaw”) in April 2017. The Heritage Bylaw establishes minimum maintenance standards for protected heritage properties. Changes to the Tax Exemption Policy as a result of this, the Heritage Bylaw and other legislation have been recommended under the corporate report for Section 220 and 224 exemptions. Specifically, the following requirement for consideration of a permissive property tax exemption has been proposed:

"Heritage Properties (Section 225) Council may exempt those properties protected by Heritage Designation or Heritage Revitalization Bylaws, and which meet or exceed the minimum maintenance standards regulated by Bylaw No. 18931. In addition, the property must be in compliance with its associated Designation or Revitalization Bylaw. Exemption will be considered for the original maintained heritage structure only. Added improvements or reconstructed structures are not eligible for permissive exemption under this Section."

The City received applications from the owners of 15 properties that have an active Heritage Designation Bylaw or Heritage Revitalization Agreement Bylaw including two (2) new applications. In each case, the application was reviewed by a staff team and verifications conducted by the Planning Department to ensure that the related property met the criteria outlined in the Heritage Property Standards of Maintenance Bylaw and the City policy for such an exemption. All 15 properties have been included in the recommended Bylaw attached as Appendix "I" to this report. The public notification process as outlined in legislation requires that an estimate of the total value of the property tax exemptions proposed under the Bylaw be provided for each of the following 3 years. The following is a list of such estimates for the subject Bylaw:

2018 $58,942 2019 $61,240 2020 $63,629

New Applications: 1. Port Kells Fire Hall No. 7, 18922 – 88 Avenue, Schedule A, Item 8

Council adopted Heritage Revitalization Bylaw No. 19279 on July 27, 2017. It is intended that this historic fire hall will have multiple uses upon completion of renovations. The property has been added to the schedule to the Bylaw for 2018 exemption.

2. Robert Dougal MacKenzie House, 5418 – 184 Street, Schedule A, Item 10

Council denied exemption in 2017 for this property for contravention of the Controlled Substance Property Bylaw No. 15820. The applicant is once more in good standing, and the property has been added to the schedule to the Bylaw for 2018 exemption.

Application Changes: 1. Arthur Hedley House, 11927 – 96A Avenue

No application was received for this property. The owner indicated in 2016 that he was planning to sell the property.

There were no other changes to the properties that received permissive tax exemption in 2017. CONCLUSION Based on the above discussion, it is recommended that Council authorize the City Clerk to bring "Section 225 Tax Exemption Bylaw, 2017, No. 19349" forward for the required readings Jane Sullivan City Clerk Appendix "I": "Section 225 Tax Exemption Bylaw, 2017, No. 19349" h:\clerks\staff committees\tax exemption committee\2018\rpt 2018 corporate report 225.docx
