Abstract

This paper presents an attempt to explore the applicability of harmony search algorithm (HSA) to solve extremely challenging non-convex economic load dispatch (ELD) problem with transmission losses involving variations of consumer load patterns. The efficiency of the proposed approach HSA has been tested successfully on the standard 6-bus system, IEEE-14 bus system, and the IEEE-30 bus system with several heuristic load patterns. The results of this study reveals that the proposed approach is able to find appreciable economical load dispatch solutions than the improved fast evolutionary program (IFEP) and particle swarm optimization (PSO). Besides this, the transmission line losses also considerably reduced and the computation time is reasonably even in all test cases and less when compared to other methods.
