Optimal capacitor placement and sizing for enhancement of distribution system reliability and power quality using PSO

Abstract

This paper presents optimal capacitor placement and its sizing using Particle Swarm Optimization. Reactive power management and planning is one of the crucial issues in front of researcher from last four decades in addition to voltage profile, line losses and power factor problem in transmission and distribution system. Capacitor is a device which is a solution to above problem if utilized in proper way. IEEE 30 bus system is introduced in this paper for optimal configuration of capacitor with broader multi-objective function. Reliability and its indices as discussed in IEEE std 493 and 1366 are benchmark studies followed by all researchers. Placement of capacitor in proper way will Enhance the distribution system reliability is discussed in this paper. Particle Swarm Optimization technique is used to evaluate objective function for capacitor placement and sizing in IEEE bus system.
