This invention discloses a compressed air energy storage system and its operation method, belonging to the field of physical energy storage technology. It includes a compressed air energy storage module, a transcritical carbon dioxide heat pump module, an electric heating module, and a heat storage module. The compressed air energy storage module includes an air compressor unit. The heat absorption side of the transcritical carbon dioxide heat pump module is coupled to the interstage cooling circuit of the air compressor unit to absorb compression heat and cool the interstage air. The heat release side is coupled to a first heat storage unit to upgrade the compression heat into high-grade heat storage. The high-pressure stage compression circuit is coupled to a second heat storage unit to transfer the high-pressure stage compression heat. The electric heating module uses electrical energy components unsuitable for driving the compressor to supplement and raise the temperature of the heat storage medium in the second heat storage unit, forming a secondary high-grade heat storage. During energy release, the high-pressure air is first preheated using the secondary high-grade heat and then reheated between stages using the high-grade heat. This invention achieves a comprehensive performance improvement by reducing compression power consumption, increasing work capacity, and completely absorbing fluctuating electrical energy.
