ABSTRACT
Now a day’s, Distributed generators (DGs) penetration level is rapidly increasing pertaining to electricity market restructuring and environmental issues. DGs also playing a role of minimizing line losses in power system network; the sizing and placement of DG’s should be done with utmost care to avail the maximum benefits. The inherent features of radial distribution network with large number of nodes and variable X/R ratio’s out ruled the conventional techniques for DG’s sizing and optimum placement. So, artificial bee colony method is presented in this paper to obtain the optimal location and sizing of DG with loss minimization. The proposed method is tested on 25-bus unbalanced radial distribution system and the results are compared with those of particle swarm optimization (PSO) and improved group search algorithm methods to show the superiority of proposed methodology.
