Optimal Allocation of DG Considering Loss Minimization and Voltage Profile Using PSO

Distributed Generation integration in distribution system is one of the options which give many benefits like loss minimization, peak saving, over load relieving, voltage profile improvement, power quality and improved reliability. The installation of DG units at non-optimal places can result in an increase in system losses, damaging voltage state. In this paper, objective function is designed for optimally determining the location of distributed generation, distribution system for power loss reduction and voltage profile improvement are presented. Newton Raphsons Power flow method with particle swarm optimization algorithm (PSO) is used and the effectiveness of the proposed method is tested on IEEE 33- bus radial distribution systems to demonstrate the performance and in the presence of distributed generation (DG). Results show the efficiency of the proposed algorithm in reducing power losses, improving voltage profile.
