Capacitor Bank and DG Optimal Placement in Order to Achieve the Minimum Active Power Losses by PSO

This paper develops an optimal placement technique in order to sizing and placement of distributed generation and capacitor banks in IEEE 33 bus test system simultaneity. The optimization algorithm in this article is Particle Swarm Optimization. The proposed objective function considers active power losses of the system in nominal load of system. In order to use of Particle Swarm Optimization algorithm placement problem is written as an optimization problem which includes the objective function and constraints, then to achieve the most desirable results, Particle Swarm Optimization (PSO) 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 illustrate of feasibility of proposed method this optimization in two cases – one DG unit with one capacitor bank, Two DG units and two capacitor banks - will accomplish.
