Application of Evolutional Algorithms for Productivity Improvement and Reduction of Active Power Losses in Radial Distribution System

Abstract: Power losses in distribution system have become the most concerned issue in power losses analysis in any power system. In the effort of reducing power losses within distribution system, reactive power compensation has become increasingly important as it affects the operational, economical and quality of service for electric power systems. This paper presents a new method for determining capacitor placement in radial distribution systems. The capacitor placement problem consist of finding size & places to install capacitor bank in an electrical distribution network aiming to reduce losses and voltage profile Improvement due to the compensation of the reactive component of power flow. The capacitor placement is hard to solve in sense of global optimization due to the high non linear and mixed integer problem. To solve the problem efficiently, this paper by Genetic Algorithm (GA) and Colonal Selection Algorithm (CSA) that is one of the efficient optimization methods
