Power System loss minimization by using UPFC placed at optimal location given by Artificial Bee Colony Algorithm

Abstract

In this paper, heuristic technique based minimization of losses in the power system using Unified Power Flow Controller is proposed. Here, the Artificial Bee Colony Algorithm (ABC) optimizes the location of the UPFC, while the generator outage occurs. The optimum location is referred as the maximum power loss bus, because the generator outage affects the power flow constraints like power loss, voltage magnitude, real and reactive power. By using UPFC at the optimum location minimum power loss is attained. Then UPFC is placed in the optimum location and the corresponding results are analyzed. The proposed method is implemented in the MATLAB/Simulink platform and the performance is evaluated by using the comparison power loss at different conditions. The comparison results demonstrate the superiority of the proposed approach and confirm its potential to solve the problem.
