Economic Load Dispatch Using Linearly Decreasing Inertia Weight Particle Swarm Optimization

Economic load dispatch (ELD) is an optimization task in power system. It is the process of allocating generation among the committed units such that the constraints imposed are satisfied and the fuel cost is minimized. Particle swarm optimization (PSO) is a populationbased optimization technique that can be applied to a wide range of problems but it lacks global search ability in the last stage of iterations. This paper used a novel PSO with a inertia weight Improved (IWIPSO), which 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 NWIPSO algorithm is demonstrated through its application for 13 & 15 generator systems with constraints.
