Optimal Placement of Distributed Generation Sources in Order to Reduce Loss and Improve Voltage Profiles in Power Distribution Networks Using Genetic Algorithms

Abstract

In this paper, an optimal placement undertaken by the DGs in radial distribution system was presented and optimization parameters in determining the optimal placement of DG reducing losses and improving the increase of voltage profiles were reliable. To solve the problem, genetic algorithm with real codes and backward – forward power-flow method based on the distribution network was used. All cases were analyzed and calculated by the MATLAB programming software and on the IEEE 20-bus network. Finally, the losses with and without DG insertion were shown which confirmed we worked properly.
