Optimal Multi Objective sizing and sitting of Distributed Generation on Distributed Networks using SMPSO

In this study a multi objective optimization tool is employed to determine the optimal placement of Distributed Generation (DG) in distribution networks. The two objective functions considered for minimization are DG cost and system total power loss. Speed-constrained Multi-Objective Particle Swarm Optimization (SMPSO) algorithm is utilized to find optimum sizes and places of DG units. The SMPSO attempts to optimize each objective separately and finally yields many solutions, all of which are optimal and have no superiority to one another. Depending on the economic and technical aspects, designer can pick out a solution.
