The invention belongs to the technical field of energy storage power generation, and particularly relates to a compressed air energy storage power generation system and method based on jet flash evaporation. A compressed air energy storage power generation system based on jet flash evaporation comprises a compression subsystem, an energy storage subsystem and an expansion energy release subsystem. The compression subsystem is formed by connecting more than two stages of compressor units in series; the energy storage subsystem comprises a storage tank, a first valve, a second valve, a storage tank working medium pump, more than one stage of heat storage heat exchanger, a circulating liquid inlet pipe and a circulating liquid outlet pipe; the compression subsystem utilizes surplus electric quantity to compress air to obtain high-temperature and high-pressure air, the energy storage subsystem converts energy in the high-temperature and high-pressure air into internal energy of a high-temperature and high-pressur
