摘要：Distributed generators are very much beneficial in reducing the losses effectively compared to other methods of loss reduction .In this paper optimal size of DG unit operated at optimal power factor is dealt. DG unit placement using fuzzy logic and sizing of DG at any power factor is calculated using analytical method . Voltage and power loss reduction indices of distribution system nodes are modeled by fuzzy membership functions. Fuzzy inference system containing a set of rules is used to determine the DG unit placement. DG units are placed at buses with the highest suitability index. Simulation results show that optimal DG unit placement and sizing at 0.8 power factor is very efficient. Single DG unit of optimum size operated at 0.8 power factor is sufficient in reducing losses and improving voltage regulation effectively within the specified voltage constraints.
