Abstract:

Economic load dispatch (ELD) is an optimization problem and defined as the process of allocating generation levels to the committed generating unit at minimum cost while satisfying all physical & operational constraints. Eberhart and kennedy suggested Particle Swarm Optimization (PSO) used to solve NonConvex Economic Dispatch(NCED) problem. The performance of PSO is governed by its parameters i.e. inertia weight, acceleration coefficients, random number generation, attraction towards best and global best value, Among all performance parameters of PSO, inertia weight, is very important, which can approaches in fuzzy or linear way. In present work two strategies of Exponential Decreasing Inertia Weight Particle Swarm Optimization (EDIW-PSO) have been used to determine the ELD for 15 units IEEE systems. The effectiveness of proposed algorithm shown superior result in terms of convergence and solution quality.
