Simultaneous Optimal Placement and Sizing of Distributed Generation Resources and Capacitor Banks in Unbalanced Distribution Network for Reliability Improvement and Losses Reduction

Determining the location and the capacity of distributed generation resources (DGRs) and Capacitor banks (CBs) in the distribution network are two important and effective indices on power losses and improving network performance. This paper proposed ABC algorithm to locate and determine the optimal capacity of DGRs and CBs. The objective function was considered a combination of the two loss reduction function and the energy not supplied (ENS) as reliability criterion, used in algorithms by applying the weight coefficients in the form of an objective function. for evaluation of proposed method, this method was implemented on the IEEE ۳۷-bus unbalanced network. The results of the proposed method were compared with the results obtained from GA and PSO algorithms to confirm the results. The simulation results show the more proper efficiency and performance of the proposed algorithm when it is compared with other algorithms.
