基于风-蓄协调的蓄能机组发电控制策略分析

基于风电与抽水蓄能电站联合调度模式,分析了风能-抽水蓄能联合发电系统的运行方式,探讨了蓄能机组发电控制策略,并以某实际抽水蓄能电站的库水位为约束条件进行了仿真分析。仿真结果表明,联合发电系统与电网的负荷交换功率能够很好地跟踪负荷给定曲线,在最大程度利用风能的条件下,在一定程度解决了风电的波动与不可调节问题。

Power Generation Control Strategy of the Wind Power and Pumped Storage Combined System

The joint dispatching mode and the combined operation manner of the wind power and pumped storage com -bined system are analyzed .The power generation control strategy of this combined system is discussed .A simulation with the actual water level of a pumped storage power station is carried out .The results show that the load exchange pow-er of the combined power generation system to the power grid could nicely follow the load curve .Thus, the wind power could be maximally exploited .Also, problems of the wind power such as the fluctuation and regulatory difficulty could be alleviated.
