Improved Whale Algorithm for Economic Load Dispatch Problem in Hydropower Plants and Comprehensive Performance Evaluation

A novel method for economic load dispatch problem (ELDP) based on improved whale optimization algorithm(IWOA) is presented, and the performance of IWOA in ELDP was evaluated comprehensively. The search mechanism modified to improve ability algorithm jump out local optimal. adaptive nonlinear inertia weight introduced convergence speed algorithm. limited mutation proposed evaluation indicator calculation time accuracy established. Taking 26 units Three Gorges Hydropower Station as an example, genetic aigorithm (LAGA), particle swarm (PSO), (WOA) (IWOA) were used solve ELDP. result shows that superior other algorithms results various heads loads. better than WOA when number turned more 6. analysis DP show indicators this paper provide a new way solving large hydropower stations.
