某水电站群优化调度模型大系统分解协调算法

Study on large-scale system decomposition and coordination method for optimal operation of Qingjiang Cascade Hydropower Stations

根据串联水电站群的特点,以清江流域水布垭、隔河岩、高坝洲水电站为例,建立了梯级间流量传播影响和电力联系的3级串联水电站优化调度的大系统分解协调模型,大系统分解协调算法较传统算法计算效率更高,可为大流域跨省区的复杂并联、混联水电站群多目标优化调度模型的构建、问题分解及算法等方面提供参考。

According to the ch aracteristics of the cascade hydropower station group, taking the Shuibuya, Geheyan and Gaobazhou hydropower stations in the Qingjiang River Basin as an example, a large system decomposition and coordination model, for the optimal operation of the three cascade hydropower station, is established considering the influence of the interflow flow and the power connection. The algorithm of large system decomposition and coordination is more efficient than traditional＇s and it can be used as a reference, for the construction of complex multi-objective optimal dispatching model, the decomposition of the problem, and the algorithm for the complex parallel connection of the trans-provincial provinces.
