Loss Reduction Using Optimal Placement and Sizing of Distributed Generator

Abstract

By harvesting the power at distribution side, it has its own significant impact on distribution system. These distribution generators (DGs) improve the voltage profile of each bus and reduce the losses of the system if the DGs are places at optimal place on the distribution system and with optimal size of the generation. In order to achieve the optimal place and size, particle swarm optimization (PSO) is proposed in this study and the performance of proposed algorithm is compared with the genetic algorithm (GA). To test IEEE-38 bus system is taken as the reference system. The observation shows the PSO gives the better optimized values than the GA.
