Comparison of optimal DG placement using CSA, GSA, PSO and GA for minimum real power loss in radial distribution system

The efficient use of Renewable Energy Systems as DG's in the distribution sector requires that the losses, arising out due to their existence in the system, to be minimum. This can be achieved by placing a properly sized DG at an optimal location in the system. Using an optimization technique is one method to solve such a purpose. In this paper, optimal DG placement and sizing has been presented using selected four heuristic search based methods. The main objective of the paper is: (i) DG location and sizing determination based on loss minimization criteria and (ii) comparison of four selected heuristic search based methods. The analysis has been carried out for IEEE 33 radial bus test system.
