This article proposes a hybrid global-local algorithm – Hybrid Particle Swarm Optimization (HPSO) – applied to solve the Economic Dispatch (ED) problem. The HPSO algorithm combines the classical Particle Swarm Optimization (PSO) with the Conjugate Gradient (CG) non-linear optimizing method, included in the optimizing tool within MathCAD commercial software product. The global optimizer is the […]
