摘　　要：基于状态转移矩阵的确定性离散动态规划(DDDP)方法是在考虑水库运行的综合利用的前提下,利用状态转移矩阵寻找出梯级水库优化调度过程中所有的可行策略,基于目标函数逆向搜索可行策略,得出最优解的优化算法。该方法可进行单库优化计算,也可以进行梯级水电站优化计算。文中以锦屏梯级为例,说明该方法可在满足梯级水库上下游生态用水、发电用水等综合利用的前提下,以梯级水电站发电效益最大为目标,求得梯级水库优化调度的较好解。Considering the complex utilization of reservoir operation,the state transformation matrix-based deterministic diseretized dynamic programming （DDDP） method is an optimization algorithm to find out all possible strategies in the process of optimal operation of cascade reservoirs using the state transformation matrix,which reverse searches the practical strategy based on the objective function. This method can be used for a single reservoir calculation and cascade hydropower stations calculation. Taking the Jinping Cascade Reservoirs as an example,the method is illustrated. It is shown that,with this method,a better solution can be obtained which,under the condition of meeting the requirements for water for ecological and hydroelectric use between the upstream and downstream of cascade reservoirs,can maximize power generation efficiency of the cascade hydropower stations.
