Application of a particle swarm optimization in an optimal power flow

Abstract

In this paper an efficient and Particle Swarm Optimization (PSO) has been presented for solving the economic dispatch problem. The objective is to minimize the total generation fuel and keep the power outputs of  generators; bus voltages and transformer tap setting in their secure limits. The conventional load flow and  incorporation of the proposed method using PSO has been examined and tested for standard IEEE 30 bus  system. The PSO method is demonstrated and compared with conventional OPF method (NR, Quasi Newton), and the intelligence heuristic algorithms such ac genetic algorithm, evolutionary programming. From   simulation results it has been found that PSO method is highly competitive for its better general convergence performance.

Keywords: Load flow, Optimal Power Flow, Power System, Particle Swarm Optimization (PSO).
