Chicken Swarm Optimization for Economic Dispatch with Disjoint Prohibited Zones Considering Network Losses

Economic dispatch problem is one of the optimization problems in power system. This paper attempts to investigate the applicability of Chicken Swarm Optimization algorithm (CSO) to solve extremely challenging non-convex economic load dispatch problem with valve point loading effect, prohibited operating zones, ramp-rate limits and transmission losses involving variations of consumer load patterns. The performance of the proposed approach CSO has been tested successfully on the standard 6-unit system and 15-unit test systems with several heuristic load patterns. The results of this study reveal that the proposed approach is able to find appreciable economical load dispatch solutions than some recently published results. Besides this, the transmission line losses are also considerably reduced and the computation time is reasonably even and less when compared to other methods.
