摘　　要：针对目前改进动态规划算法和智能优化算法在梯级水电站联合调度求解过程中的非全局最优解,本文以清江梯级水电站为研究对象,提出二维嵌套动态规划算法进行优化调度,调度中考虑上游水电站每一次的出流过程对于中下游两水电站发电量的影响,中游水电站每一次的出流过程对于下游水电站发电量的影响,并将优化调度结果与实际调度、常规动态规划调度进行对比,取得了很好的效果,为梯级水电站的联合调度提供了一种全局调度的思想和方法。In view of the problem of non-global optimal solution of dynamic programmiog and intelligent optimization algorithms in the joint scheduling of easeadc hydropower stations, taking Qingjiang cascade hydropower stations as research object, a two- dimensional nested dynamic programming algorithm is proposed to optimize the scheduling. In proposed joint scheduling algorithm, the influences of the outflow process of upper hydropower station on the power generations of middle and lower hydropower stations, and the influence of the outflow process of middle hydropower station on the power generation of lower hydropower station are all taken into account. Compared with the actual scheduliug and conventional dynamic programming scheduling, the proposed scheduling can obtain ideal power generation efficiency, which provides a global idea and method for the joint scheduling of cascade hydropower stations.
