Distributed generation (DG) units reduce electric power losses and hence improve reliability and voltage profile. Determination of appropriate size and location of DG is important to maximize overall system efficiency. In this paper, an optimization method has been presented to determine the appropriate size and proper allocation of DG in a distribution network. Results obtained from this method have been compared with using the repeated load flow method. A new approach to perform repeated load flow by using simulation engine `openDSS' COM server through Matlab programming is also introduced here. Both optimized method and repeated load flow based method have been compared for three IEEE distribution test systems. This analysis shows that using appropriate size and location of DG, total power loss in primary distribution system can be reduced significantly.
