OPTIMAL PLACEMENT OF TCSC FOR VOLTAGE CONSTRAINED LOSS MINIMIZATION USING SELF-ADAPTIVE FIREFLY ALGORITHM

Abstract

Thyristor Controlled Series Compensator (TCSC) is series compensating Flexible Alternating Current Transmission System (FACTS) Controller in power system network. The objective is to minimize the transmission loss besides keeping the voltage magnitude within the acceptable range. Using proposed strategy, the location of TCSCs and their parameter are optimized simultaneously. Self Adaptive Firefly Algorithm (SAFA) is proposed to solve the above optimization problem for better accuracy. The TCSC placement strategy is tested on three IEEE test systems and their results are presented to demonstrate its effectiveness.
