Optimal Placement of Capacitor Banks in order to Improvement of Voltage Profile and Loss Reduction based on PSO

並列摘要


This study develops an optimal placement method in order to sizing and sitting of capacitor banks in IEEE 33 bus test system. The proposed method in order to optimization in this article is Particle Swarm Optimization and the objective function is composed of two parts. The most part of proposed objective function considers improvement of voltage profile and other part is active power losses of the system in nominal load of mention system. In order to use of Particle Swarm Optimization algorithm, at first, placement problem is written as an optimization problem which includes the objective function and constraints, and then to achieve the most favorite results, Particle Swarm Optimization (PSO) method is applied to solve the problem. High performance of the proposed algorithm in mention system is verified by simulations in MATLAB software and in order to prove of feasibility of proposed method this optimization in three cases-one capacitor bank, two capacitor banks, and three capacitor banks-will accomplish.
