Abstract: A flexible peak regulation system and method for air energy storage by a power plant, the system comprising a liquid compressed air energy storage system and a coal-fired unit power generation system. The operation modes of the system comprise an energy storage mode and an energy release mode. The energy storage mode is started up when the power utilization load of a power grid is low and residual electrical energy exists, and the residual electrical energy is used for driving a multi-stage compressor (1, 21) to compress air. The energy release mode is started up when the power utilization peak of the power grid is short of the electrical energy supply, and low-temperature air is heated by using steam extraction by the coal-fired unit so as to push an expansion machine (6) to generate power and output electrical energy to the outside. In the described system, the efficiency of the energy storage system can be improved, while the problems of high energy consumption, short service life and so on, which are faced when a high-pressure ratio compressor is used, are prevented. In the described system, a heat storage system in a traditional liquid compressed air energy storage system is omitted, thus investment in the energy storage system is reduced, while the problem in which the heat in an energy storage process and in an energy release process does no match is solved.
