摘　　要：面向水库汛末蓄水、发电兴利和下游抗旱补水需求,构建多目标汛末蓄水调度模型,进而提出改进多目标差分进化算法对模型优化求解.该算法通过改进差分进化算子,提出基于反学习策略的初始化和灾变操作,引入自适应小生境精英集维护策略,提高算法的收敛性和多样性.通过对三峡水库汛末蓄水调度实例研究,验证了该算法求解水库蓄水调度问题的有效性,并分析明确了三峡水库汛末蓄水调度目标间相互影响的变化规律.研究可为水库汛末蓄水调度决策提供技术手段和科学依据.Focusing on the reservoir impounding in flood recession period,power generation and downstream water supply,the multiobjective impounding operation model is established.And then an improved multiobjective difference algorithm is proposed to solve the model.By advancing the difference evolution operators,proposing the opposition learning strategy based initialization and population mutation,adding an adaptive niche method based archiving set,the improved algorithm has better convergence and diversity.Furthermore,the case study of Three Gorges Reservoir shows that the proposed algorithm can effectively solve the reservoir impounding operation problems.The results reveal the change rules of operation objects.This research can provide solution method and scientific basis for reservoir impounding operation in flood recession period.
