Optimal Supplementary Controller Design for IPFC to Damp Low-Frequency Oscillations in Power Systems

Abstract

Abstract: In this paper, the use of interline power flow
controller (IPFC) on damping low –frequency oscillations
(LFOs) are discussed and a new genetic algorithm(GA)-based
multistage fuzzy (MSF) DC-Voltage regulator is proposed for
IPFC to dampen low- frequency oscillations in (Double line)
power system. The suggested control strategy is
estimated under various operating conditions, and then it is
compared with conventional controllers to determine its
effectiveness. Time-simulation studies proved the robust
performance of the proposed regulator.
