摘　　要：建立了梯级水电站短期周优化调度的梯级蓄能最大模型,在此基础上采用动态搜索算法对其进行求解。通过严密的理论推导和详尽的实例分析探讨了流域梯级电站负荷最优分配规律。梯级电站负荷最优分配主要由梯级水库的区间入流关系和水库特性决定,其结论可指导流域梯级电站优化运行,为集控中心调度和指导实际应用提供参考。调度决策者尚需根据本文的研究方法针对本流域和电站的特性制定符合自身的最优调度规则。This paper establishes a maximal energy storage model of the dynamic searching algorithm for the short-term weekly optimal scheduling of cascade hydropower stations,and discusses the optimal load allocation by adopting strict theoretical derivation and detailed analysis of an application case.It is shown that the optimal allocation depends on the runoff relations and the characters of cascade reservoirs.For the centralized control,the conclusions of this paper could be useful for the practical optimal scheduling of cascade hydropower stations.For decision making on the optimal scheduling rule,the presented method should be applied in combination with a study of the specific basin characters.
