Bat Search Algorithm Based Hybrid PSO Approaches to Optimize the Location of UPFC in Power System

FACTS devices plays a significant role to control the power flow of power transmission system. In this paper, a hybrid PSO algorithm is proposed to optimize the location of UPFC in power system. The proposed hybrid PSO algorithm has solved the formulated multiobjective optimization problem. This paper, five objective function to be considered in the form of minimization such as the fast voltage stability index (FVSI), fuel cost, power loss, voltage deviation and UPFC cost respectively. To improve the non satisfied solution of PSO algorithm, bat search optimization is used and the performance of PSO algorithm is enhanced. The proposed hybrid technique is implemented in MATLAB working platform which is tested with IEEE 14 bus bench mark system. Here, two load cases are considered to evaluate the proposed method and compared with traditional PSO algorithm. The comparative analysis are conformed the effectiveness hybrid PSO algorithm for solving multiobjective optimal power flow problem.
