Abstract

This paper elucidates a Particle Swarm Optimization method (PSO) for optimal placement of Unifed Power Quality Conditioner (UPQC) for loss reduction and voltage profile improvement in the radial distribution systems. UPQC comprises of a series and a shunt compensator. The shunt compensator delivers reactive power to meet the load reactive power demand. The series compensator takes part in voltage compensation. This paper gives an insight into the usefulness of UPQC in which the series compensator also shares part of the reactive power in steady state conditions such that the UPQC is utilized optimally. PSO is utilized to decide the optimal location and rating of UPQC. The proposed optimization method is applied to standard distribution systems.
