Optimal allocation of DG in the radial distribution network using bat optimization algorithm

Abstract

In the present era, the optimal allocation of Distributed Generation (DG) at the distribution end is becoming significant due to environmental and economic issues, to deduce the power loss and also to improve the voltages between the buses. In this paper authors focused to address the optimal sitting and sizing of DGs in the distribution networks by using nature inspired Bat Algorithm (BA). In addition in this study, two different kinds of DGs have been considered. The main aim of the present work is to reduce the network real power losses. The location and sizing of different types of DGs can be determined by implementing BA. Further, to verify the effectiveness of the proposed method, IEEE 33-bus RDS is chosen. The obtained results of the proposed method is compared with other optimization based techniques. The simulation results specify that allocation of DGs in the RDS can significantly decrease the network power losses.
