摘要

This paper presents the design of an effective control strategy for frequency stability enhancement in two-area Thermal-Thermal power system under deregulated environment based Competitive Electricity Markets. The suggested control strategy involves an intelligent Load Frequency Control (LFC) based optimized PID controller employing Firefly Algorithm (FA). Additionally, the LFC loop was coordinated with Redox Flow Batteries (RFB). Moreover, to improve the tie-line power flow stability and compensate LFC capacity, impacts of two kinds of power flow controllers namely the Interline Power Flow Controller (IPFC) and Unified Power Flow Controller (UPFC) have been also investigated. The developed test system comprises: GENCOs, TRANSCOs and DISCOs, where the simulation was performed under deregulated market structure by considering the concept of DISCOs Participation Matrix (DPM). To show the effectiveness of the proposed control strategy, three scenarios were presented. Initially, the simulation was carried out under Pool-co Transaction and then under Bilateral Transaction and finally the study was extended under Contract Violation. Furthermore, to demonstrate the potential of the proposed methodology a comparative study was done. The obtained simulation results from this work show that the proposed control strategy presents a very effective means for providing robust ancillary frequency control in a deregulated power system.
