PSO Based Optimal Placement and Setting of FACTS Devices for Improving the Performance of Power Distribution System

Power systems, under heavily loaded conditions, are at high risks of probable line outage and consequent voltage instability problem. Real power loss and voltage deviation minimization are reliable indicators of voltage security of power system networks. This paper proposes a Particle Swarm Optimization (PSO) based algorithm for the optimal location and setting of FACTS devicesto improve voltage stability. Particle swarm optimization technique optimizes the locationand setting of SVC, which is used in this paper as FACTS device.The effectiveness of the proposedalgorithm has been tested in IEEE-14 Bus standard test system.
