With the rapid development of the wind power industry, the wind power wind abandoning phenomenon is more and more serious. By utilizing the energy storage system, on one hand, unstable wind power is converted into stable energy, the stability and reliability of power transmission of a wind power plant are ensured, the stability of grid-connected operation of the wind power plant is enhanced, on the other hand, the utilization rate of the wind power is improved, the economical efficiency of operation of a wind power platform is optimized, and the waste of wind energy is reduced.
Compressed air energy storage is a large-scale energy storage technology. The cost of compressed air energy storage is one percent or even one thousandth of that of other forms of energy storage, and the power level can reach more than one hundred times that of most forms of energy storage. The energy storage device has the advantages of high energy storage density and relatively low construction cost. Compared with other forms of energy storage, the compressed air energy storage applied to the offshore wind power system has higher energy recovery benefit. Therefore, the compressed air energy storage technology has wide application prospect. However, the energy is stored by only adopting compressed air, the utilization mode is single, and the economic benefit is poor.
