Abstract—This paper proposes a genetic algorithm optimization technique for optimal placement of distributed generation in a radial distribution system to minimize the total power loss and to improve the voltage sag performance. Load flow algorithm and three phase short circuit analysis are combined appropriately with GA, till access to acceptable results of this operation. The suggested method is programmed under MATLAB software. The implementation of the algorithm is illustrated on a 34-node radial distribution system. Placement of two DGs with fixed capacity has been considered for example. Only the three phase symmetrical faults are considered for sag analysis though other fault types are more common
