梯级水电站群最优运行的递阶控制算法

An Algorithm of Hierarchical Control for Optimal Operations of Hydropower Stations in Cascades

针对位于同一电网的梯极水电站群联合运行的情况，着重研究了在枯水季节最优调度的计算模式，提出了大系统递阶控制的优化算法。该算法也同样适用于规划中的梯级水电站。实例计算表明该算法是可行的，且解析性强。

With an aim at the united operations of the cascade hydropower stations in the same electric network, this paper mainly studies the optimal disposal calculation model during the drought period, and suggests the optimal algorithm of hierarchical control in the large scale system. This algorithm is also adaptable to the cascade hydropower stations in planning. The calculations from the practical examples indicate that this algorithm is feasible and effective in analysis.
