Optimum number, placement and capacity of DGs and reclosers using analysis hierarchical process and genetic algorithm

One of the remarkable phenomena in power systems is the appearance of Distributed Generation (DGs). DGs may reduce the number and/or duration of interruptions for customer residing within their protection zones. DGs also can improve losses and voltage profile of system. In this paper a composition of Genetic algorithm (GA) and Analysis Hierarchical Process (AHP) are presented. The proposed algorithm uses GA algorithm for optimal placement and capacity of DGs and reclosers in the network. In the next stage, by using of AHP method, the optimal number of reclosers and DGs are determined based on economic and power quality considerations. This method was carried out on a modified 33 feeders IEEE distribution network. Simulation results validate the effectiveness of the proposed method.
