Reduction in power transmission loss using fully informed particle swarm optimization

Abstract: The Optimal Power Flow (OPF) problem with transmission loss as an objective function is solved using Particle Swarm Optimization (PSO) technique. PSO is employed with and without fully informed characteristic. Transmission loss is a major concern in the prevailing electrical energy crisis. The test cases used in this paper are the Ward-Hale 6-bus system, the standard IEEE 30-bus system and the standard IEEE 118-bus system. Results obtained using PSO and Fully Informed Particle Swarm Optimization (FIPS) are compared with each other and with the previously reported results in the literature. The statistical measures for fair comparison are the average power loss and the standard deviation in power loss. It has been found that FIPS outperforms PSO resulting in much reliable results.
