Optimal placement of distributed generation using genetic algorithm approach

Abstract

Nowadays there is increasing number of small scale power generations which are connected to distribution networks termed as Distributed Generation (DG). The allocation of DG in distribution networks is intended for power flow control, improvement in stability and voltage profile, power factor correction, and reduction of line losses. This paper presents an optimization approach using Genetic Algorithm (GA) to find optimal location and size of DG in radial distribution system. The objective is to minimize the active power loss keeping the voltage profile in distribution system within defined limits. The effectuality of proposed approach is checked on IEEE 33 bus and 69 bus test systems.
