Particle Swarm Optimization for economic dispatch problems with valve-point effects

Laplace Crossover Particle Swarm Optimization (LXPSO) is a variant of Particle Swarm Optimization (PSO) which employs Laplace Crossover to PSO. LXPSO is already proven to be cost effective and reliable for the test problems of continuous optimization. Economic dispatch (ED) problem is one of the fundamental issues in power system operations. The problem of economic dispatch turns out to be a continuous optimization problem which is solved using original PSO and its variant LXPSO in expectation of better results. Results are also compared with the earlier published results.
