Abstract: 

This research paper has been presenting a comparative analysis of power flow in radial distribution system before and after optimal locating and sizing of Distributed Generation (DG). In this paper the power flow analysis is using to obtain the real power loss and voltage at each bus with the BAT Algorithm (BA) and the conventional Gravitational Search Algorithm (GSA). Finally the conventional GSA has been comparing with the BA to prove that the BA will provide the better solution for optimal placement of DG and size. This research also presenting the optimal placement of DG and its size in order to reduce power loss and improve the voltage profile at each bus in the system. By using Forward and Backward (FW/BW) sweep analysis initially analysing the power losses in the system. Then by using GSA and BA the power loss and voltages at each bus will be calculate and also the optimal location and size of the DGs to reduce these losses will calculate. For this research the Photo Voltaic (PV) energy is considering as DG. All the methods for this research are computing by using MATLAB software and for the test the IEEE-33 radial bus system has considered.
