Original Contribution


In order to analyze the distribution system (DS) to minimize the power losses and improve power quality, finding accurate position size of distribution static compensator (D-STATCOM) is essential. In this paper, a metaheuristic optimization technique, the gravitational search algorithm (GSA) is proposed for the analysis of DS with accurate placing and sizing of distributed static synchronous compensator (D-STATCOM) for power loss reduction, minimum voltage profile index, improvement in voltage profile and annual energy saving for distribution network operator. The effectiveness of the proposed algorithm is tested on IEEE 33 and IEEE 69 bus systems, and performance of GSA has been compared with other techniques such as immune algorithm, bat algorithm and sensitivity approach method for optimal allocation of D-STATCOM. It is found that the best performance is achieved by the proposed method. Forward–backward sweep method is used for the load flow solutions in this paper.
