摘要
由于新能源对电网的渗透刺激了储能领域对大容量的需求,对风-光-抽水蓄能系统进行容量设计研究,建立了包括太阳能光伏、风能和抽水蓄能水电站在内的联合系统运行的数学模型。结果表明:水电站利用海水作为一个下水库,只需建造一个上水库就可以降低蓄水系统的安装成本;当光伏发电和风力发电产生剩余电量时,上水库进行抽水蓄能;当光伏电站和风力发电输出不足时,从上水库排水发电。
The demand for large capacity energy storage is stimulated as the integration of new energy into the power grid. In this paper, the capacity design of wind-photovoltaic power-pumped storage system was studied, and the mathematical model of the operation of the joint system including solar photovoltaic, wind energy and pumped storage hydropower station was established. The simulation results show that the installation cost of water storage system can be reduced by building only another one upstream reservoir when using seawater as a downstream reservoir. When photovoltaic power generation and wind power generation generate surplus electricity, the upper reservoir is used for pumped storage, and while the output of photovoltaic power stations and wind power is insufficient, the electricity is generated by draining water from the upper reservoir.
