Optimal placement of different type of DG sources in distribution networks

In the present work the optimal placement of different types of DGs has been proposed. The optimal locations and size of the DG's have been determined by minimizing the power distribution loss. The optimal power factor for DG supplying, both real and reactive power, has been obtained in this work. Different types of DGs supplying real and reactive power at different buses have also been considered in the proposed approach. The particle swarm optimization (PSO) technique has been used to solve the optimal placement of DGs. The results obtained from the PSO technique have also been compared with the analytical approach results. The proposed technique is tested on 33-bus and 69-bus test systems.
