Over the last few years, Distribution Generations (DGs) are fast finding their importance in solving growing environmental problems and rising energy demands. However, installation of DG in distribution network may have positive or negative impacts on power system depending on system configuration and local issues. Bat Algorithm (BA) with varying loudness and pulse rate is proposed in this paper for the optimal location and sizing of DG in radial distribution system in order to minimize real power losses and maximize voltage stability index (VSI), along with improving voltage profile within the range of the voltage constraint. Two cases based on either real or both real and reactive power generating capability of DG is considered. Both the cases include single as well as multiple DG units for performance analysis of DG on IEEE 69 bus systems. To verify the efficiency of proposed method a comparison is made with Standard Particle Swarm Optimization (PSO). The simulation results reveal that Bat Algorithm (BA) is better than PSO in terms of power losses, VSI and quality of solution. © 2016 IEEE.
