Optimized distributed generation planning for radial distribution system using particle swarm optimization algorithm

Abstract

Electrical generation and storage by a range of small grid-connected or distribution systemconnected devices known as distributed energy resources is distributed generation. This paper presents the determination of the optimal position of a Distributed Generation (DG) Unit. There has been analysis of the radial distributed network. The placement of distributed generation and the size of the distribution generation is a prime factor here. The key motive of this paper is to minimize line losses and improve voltage profile. We have followed a robust technique called particle swarm optimization to achieve this objective. The application is illustrated on a 30 bus system of 132KV line Chittagong, Bangladesh power Grid system using Newton Raphson power flow method. Results presents the maximum reduction of real power loss in percentage and optimal location of Distributed Generation.
