This book presents a hybrid technique combining Quasi-Oppositional with Enhanced BAT (QO-EB) algorithm to solve both convex and non-convex nature of the economic load dispatch (ELD) problems of thermal power generating units considering transmission losses and constraints such as power balance, valve-point loading and prohibited operating zones. This book shows the feasibility of hybrid technique for solving ELD problems of 3-unit, 6-unit, 15-unit, 40 unit and 140-unit systems. A qualitative comparison of the obtained result with the other standard population-based meta-heuristic techniques manifests the superiority of the above proposed Quasi-Oppositional Enhanced BAT Optimization Algorithm.
