Economic Load Dispatch with Valve Point Loading Effect and Generator Ramp Rate Limits Constraint using MRPSO

Economic load dispatch is the process of allocating generation among the committed units such that the constraints imposed are satisfied and the fuel cost is minimized. In this work proposed a new Particle swarm optimization with moderate random search. Particle swarm optimization is a population based optimization technique that can be applied to a wide range of engineering problems. Particle swarm optimization with a moderate-random-search strategy called MRPSO, enhances the ability of particles to explore the solution spaces more effectively and increases their convergence rates. In this paper the power and usefulness of the MRPSO algorithm is demonstrated through its application to three and six generator systems with valve point loading effect and ramp rate limit constraints.
