抽水蓄能电站在系统调度中的运用探讨

Discussion on Operation of Reservoir Power Plant in the System Dispatching

采用大系统递阶分解—协调模型 ,初步探讨了抽水蓄能电站在湖北电网中的优化运行方式。根据系统运行特点 ,以抽水蓄能电站抽水阶段与发电阶段效率最高为准则 ,用动态规划法求得各时段抽水蓄能电站的最优出力 (抽水时出力为负 )及运行优化方式。

Using the major system step dissection and correlation model, the paper gave out a preliminary discussion on the opinized operation mode of reservoir power plant in Hubei power grid. In accordance with the system operation characteristic, and on the criteria of maximizing the efficient in the water reserving and power generating periods for the reservoir plant, the paper found the best out put (out put is negative when water reserving) in each period for the reservoir plant and the opinized operation mode by using the dynamic planning method.
