ABSTRACT
Due to continuous expansion of power system in accordance with the growing demand, stability studies have become a fascinated area for research in the modern day. The aim of this paper is to identify the optimal location and size of shunt FACTS controllers in an interconnected power system under N-1 contingency for voltage stability analysis. As the size and the cost of the FACTS devices are high, an optimal location of FACTS along with its size needs to be identified before they are actually installed. In this process, we are trying to improve the voltage profile and Maximum loading Parameter while maintaining the losses under control using FACTS controllers based upon Cat Swarm Optimization (CSO).
