Optimal Placement and Sizing of Distributed Generation and Capacitor Bank for Loss Reduction and Reliability Improvement in Distribution Systems

In this paper optimum size and location of capacitors and distributed generators (DGs) are determined for reliability improvement and power loss reduction using genetic algorithm (GA). The main innovation of this paper is using both of DG and Capacitor for the reliability improvement and power loss reduction. For this purpose an objective function consisting of reliability cost, power loss cost and also DG's and capacitor's investment cost are considered. The effectiveness of the proposed method is examined in the ۱۰ and ۳۳ bus test systems and comparative studies are conducted before and after DG and Capacitor installation in the test systems. The results obtained show the effectiveness of the proposed method.
