摘　　要：针对复杂水库多目标优化调度的维数灾及易陷入局部最优的问题,提出了一种基于调度时段敏感性分析的水库调度降维新方法。该方法统一扰动年内调度时段(时间维)的不同类型调度线位置(水位或库容)参数,获得不同调度时段对目标函数的敏感度;然后以敏感时间维的各用水户调度线位置参数作为优化变量进行寻优计算;当迭代到一定代数后,再进行全局精细化搜索调度线的位置参数。实例研究表明,该降维方法在搜索效率及求解质量上均具有明显的优势,获得的调度图也具有较强的实用性。This study developed a novel dimension-reduction method based on sensitivity analysis of reservoir operation periods to solve the problems of dimension disaster and local optimum trapping in calculation of complicated multi-objective reservoir optimal operation. In this method, different types of water-supply rule curves in the operation periods（as a time dimension） of one year are disturbed uniformly so as to obtain the sensitive degree to objective functions for each of the periods. Then, the positions（water level or water storage） of these rule curves in the sensitive operation periods are taken as variables to be optimized by iterative searching. After certain steps, the iteration is switched to a finer global searching. The results show that the method has advantages in search efficiency and high-quality solution and improves applicability of water-supply rule curves.
