Offshore wind power dam pumped storage system and energy storage method
The invention belongs to the technical field of energy utilization, and particularly discloses an offshore wind power dam pumped storage system and an energy storage method.The offshore wind power dam pumped storage system comprises an offshore wind power dam, a plurality of wind driven generators, a water-turbine generator set, a water pump set and a dam inside and outside water level and energy storage control platform; the inside of the dam is a dam inner area, and the outside is a dam outer sea area; a water outlet of the water pump set is connected with a sea surface area outside the dam; the multiple wind driven generators, the water-turbine generator set, the water pump set and the dam pressure rising station are all connected with the dam inside and outside water level and energy storage control platform. The water level difference inside and outside the dam is obtained through the water pump set, power generation and energy storage are carried out through the water-turbine generator set, and electric power is input to the dam booster station and input to the power grid, so that electrochemical energy storage is replaced, the investment cost is reduced, and the energy storage capacity is large; and large-scale, long-life and high-safety energy storage of offshore wind power is realized.
本发明属于能源利用技术领域，具体公开一种海上风电大坝抽水蓄能系统和蓄能方法，包括海上风电大坝、多个风力发电机、水轮发电机组、水泵泵组和大坝内外水位及储能控制平台；大坝内部为大坝内区域，外部为大坝外海面区域；水泵泵组入水口与大坝内区域相连，出水口与大坝外海面区域相连；多个风力发电机、水轮发电机组、水泵泵组和坝上升压站均与大坝内外水位及储能控制平台相连。本发明提供风力发电机进行风力发电，风力发电富裕时对水泵泵组进行输电，通过水泵泵组获得大坝内外水位差，通过水轮发电机组进行发电蓄能，并将电力输入至坝上升压站输入至电网，替代电化学储能，减少投资成本，储能量大，实现海上风电大规模长寿命高安全性的储能。
