Background

In recent years, wind power is rapidly developed worldwide, but wind power generation also has the problems of large fluctuation of on-grid electricity quantity, low electric energy quality and the like due to the fact that the output power of the wind power generation changes along with meteorological conditions, the generation is unstable and intermittent, and the like, and is devalued as 'garbage power' by people, so that the wind power generation is difficult to access to a power grid in a large area. In recent years, the development of wind power is seriously influenced by large-scale wind abandoning and electricity limiting. In order to enhance the stability of the wind power generation system and ensure the continuous power supply to the load, the use of the wind power generation energy storage technology is more and more important. The application of the energy storage technology in the wind power generation system is mainly to store the converted electric energy source in a self energy storage mode. The energy storage technology can also ensure that enough electric quantity is stored in the power system, and the wind power generation system can be used for compensation when the electric energy is insufficient, so that the stability of the wind power generation system is improved.

The compressed air energy storage refers to an energy storage mode that power which is not easy to store, such as electricity in a valley period and wind power, is used for compressing air, compressed high-pressure air is sealed in an air storage facility, and compressed air is released to push a turbine to generate electricity when needed.

When energy is stored, the motor in the compressed air energy storage consumes electric energy a to drive the air compressor d to compress air e and store the air e in the air storage device g; in the air bleeding and power generation process, high-pressure air is released from the air storage device g, enters the combustion chamber i of the gas turbine and is combusted together with fuel h, and then drives the turbine k to drive the generator to output electric energy a.

The compressed air energy storage has the main characteristics that: the capacity is continuously increased, the operation mode is flexible, the starting time is short, the pollutants are less, the investment is less relative to that of a pumping power station, but certain geological conditions are required in abandoned mines, caves, overdue oil and gas wells or newly-built gas storage wells; the use of the air storage tank for storing compressed air requires a large-sized energy storage device, which has high manufacturing cost and difficult production, so that the air storage tank cannot be popularized and used up to now.
