Compressed air energy storage
principle
√ During the load valley period of the power grid, the electric motor drives the compressor to compress the air, converts the electrical energy into heat energy, and stores the pressure energy separately;
√ During the high load period of the power grid, the high-pressure gas in the gas storage is released, and after heat exchange, it enters the turbine drive generator to generate electricity.
function
√ Realize energy storage services such as power peak shaving, frequency regulation, phase modulation, rotary backup, and emergency response;
√ Effectively improve the safety and stability of the power system
