Solving Economic Load Dispatch Using WI-PSO
IOSR Journal of Electrical and Electronics Engineering
This paper presents a weight improved particle swarm optimization (WIPSO) algorithm to solve economic load dispatch problem of fossil fuel generating plants. The proposed methodology takes care of economic dispatch problems considering constraints such as power balance loading, ramp rate limits and generating limit. Particle swarm optimization is a population based technique that can be applied to a wide range of engineering problems. Particle swarm optimization with a weight improved-search
... improved-search strategy called WIPSO, enhances the ability of particles to explore the solution spaces more effectively and increases their convergence rate.To demonstrate the qualitiveness and effectiveness of the proposed approach, a test system consisting of three-unit generating unit, within co-orporation of power balance constraints, operating limits and ramp rate limits are taken into account.. The current proposal reveals the effectiveness and robustness as compared to other heuristic algorithms reported in literature Keywords: Economic load Dispatch (ELD), Weight improved particle swarm optimization (WIPSO), Valve point effect, Ramp Rate Limits.
