Particle Swarm Optimization Based Optimal Reactive Power Dispatch

Optimal reactive power dispatch is one of the major and important optimization problem in electrical power system operation and control. This is nothing but multi objectives, nonlinear, minimization problem of power system optimization. This paper focuses on this sub problem of optimal power flow. The particle swarm optimization (PSO) is one of the best population based intelligent technique of optimization. The basic PSO algorithm is used for optimal reactive power dispatch. This approach applies to the IEEE-14 bus, IEEE-30 bus, IEEE-57 bus and IEEE-39 New England bus test systems for minimization of active power loss. Simulation results are compared with the other optimization algorithm.
