摘要
本文对抽水蓄能机组发电工况及抽水工况的运行特性,并采用"以电定水"的运行模式,建立了以水电站耗水量最小为目标函数的数学模型。运用动态规划算法求解了某混合式抽水蓄能电站厂内经济分配,根据抽水蓄能机组的工作特性,得到了该水电站所有可带负荷的最优动力特性曲线,并拟合出相应的最优动力特性表达式。
In this paper,the working condition of pumped storage generating units and the running features of working condition of pumping,and USES the "electric water" mode of operation,establishes the mathematical model of hydropower station,the objective function is minimum water consumption.Using the dynamic programming algorithm for a hybrid pumped storage power station in the factory the economic dispatch,according to the working characteristic of pumped storage units,all the hydropower station can load optimal dynamic characteristic curve,and fitting out the corresponding optimal dynamic characteristics of the expression.
