水库群防洪优化调度模型研究

Research on optimal flood dispatching model for multi-reservoir

以澧水流域中上游的江垭、皂市及宜冲桥三库联合防洪优化调度问题为背景 ,建立了河道洪水演进方程与离散微分动态规划相结合的水库群防洪优化调度模型 ,提出了一种离散微分动态规划与马氏京根洪水演进相结合的大系统分解协调算法 .经计算分析 ,结果满意 .

Based on the optimal operation problem of flood control for multi_reservoir such as Jiangya, Zaoshi and Yichongqiao reservoirs on the Lishui river, a hierarchical model for optimal flood dispatching of multi_reservoir system, which includes a flood routing model and a discrete differential dynamic program model for the optimal flood dispatching of reservoir sub_system, is established. Then a new decomposition_coordination algorithm is put forward. The results of case study show that the mathematical model and its solution techniques are feasible and effective in practice.
