Abstract:

This paper addresses the optimal allocation of Flexible AC Transmission Systems (FACTS) devices in a power system in order to improve voltage stability. With the continuous increase of power demand, FACTS provide a suitable solution by maximizing the usage of existing utilities rather than increasing power generation and building new lines. Due to high cost of such devices their optimal allocation must be ascertained. Particle swarm optimization (PSO) is used in this paper to determine the best location and size of Static VAR Compensator (SVC) where the objective function is to achieve the accepted voltage profile taking into consideration the SVC cost. Simulations are performed on IEEE-14 test system. Results prove the effectiveness of PSO in solving such allocation problem.
