OPTIMAL SITING OF DG AND CAPACITOR BY MPSO ALGORITHM FOR LOSS REDUCTION

Abstract

Optimal placement of DG and capacitors has been proposed in this work. This paper describes an effective Modified Particle Swarm Optimization (MPSO) approach to determine best site and size of DG and capacitors in distribution systems for sake of enhancement in voltage profile and power loss reduction. Here five different cases are considered and the results are validated on IEEE-33, IEEE-34 and IEEE-69 bus distribution test systems and discussed in detail. The result shows that the placement of DG and capacitor will effectively improve voltage profile and reduces power loss in the system.
