Tang Hai-hua · Journal of Hydroelectric Engineering · 2013
This paper develops an algorithm of double-tier interaction shuffled differential evolution(DISDE) for optimal operation of cascade reservoirs to avoid performance degradation and local trapping of a regular differential evolution algorithm.This new algorithm integrates the regular global search ability and the local search ability of shuffled frog leaping algorithm,and guarantees a diversity of particles on its upper layer quipped with the niche technology and a local searching ability on its lower layer quipped with independent population evolutionary and regular correspondence.In the overall functions,the lower layer provides high-quality solution of different structures to the layer upon it,and searching information updating is completed by information interaction between the double-tier structure.Comparison with the regular differential evolution algorithm and dynamic programming of successive approximation,shows the efficiency and superiority of the new algorithm in optimization of cascade reservoirs operation.
