Voltage profile improvement and loss reduction are two goals that should be considered for providing better service for consumers in the distribution network. Several methods for this goal have been studied before that including capacitor and Custom Power Devices (CPD) installation. However, since these devices are so expensive, we must use them in minimum cost. So, for installation of these devices, the optimal location and capacity of them should be found. The study of this important issue is done in this paper, and we used Unified Power Quality Conditioner (UPQC) for steady state improvement of voltage profile and reduction of power loss. Our method is tested in 33-bus and 69-bus test systems, by using Data Sharing Algorithm (DSA).
