ROLE OF SR-PSO IN ECONOMIC LOAD DISPATCH

This paper gives an intuition regarding space reduction based particle swarm optimization (SR-PSO) to solve economic load dispatch problem of thermal generating units with valve point effects. In this study, space reduction strategy is devised to accelerate the optimization process and for obtaining the better solution in the search space. Particle swarm optimization is a population based technique that can be applied to a wide range of engineering problems. Particle swarm optimization with a search space reduction strategy 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 units, within co-operation 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.
