Where Solution of Non - Convex Economic Load Dispatch Problem with Valve Point Loading Effects Using PSO

Economic Load Dispatch (ELD) is an important optimization task in power system operation for allocating generation among the committed units such that the constraints imposed are satisfied and the operating cost is minimized. This paper presents an application of Particle swarm optimization (PSO) technique to solve non-liner, non-convex ELD problem for the determination of the global or near global optimum dispatch solution. To illustrate the effectiveness of the proposed approach, a test system consisting of 40-thermal generating units, with incorporation of load balance constraints, operating limits, valve point loadings, is considered and tested. the comparison of numerical results demonstrate the performance and applicability of the proposed method.
