Optimal Allocation of DSTATCOM Units in Electric Distribution Network Using Improved Symbiotic Organisms Search Algorithms

Abstract

This paper utilizes various proposed improved versions of the Symbiotic Organisms Search (SOS) algorithm to optimally allocate DSTACOMs in an electric distribution network to minimize power loss and to improve the voltage profiles. The performances of the three improved Symbiotic Organisms Search algorithms and the original Symbiotic Organism Search algorithm are compared applying these for a 69-bus test distribution system to optimally select one, two and three numbers of DSTATCOMs. Statistical analysis of the results establishes the robustness of the proposed improved SOS.
