  • Patent number: 10995663
    Abstract: A regenerative compressed air energy storage system and a using method thereof. The system comprises a compressor unit, a high-temperature heat exchanger, a medium-temperature heat exchanger, an air storage chamber, a regulating valve, a medium-temperature regenerator, a high-temperature regenerator and an expander unit which are connected in sequence. The low-temperature side of the high-temperature heat exchanger, a high-temperature heat reservoir, a first valve, the high-temperature side of the high-temperature regenerator, a high-temperature cold reservoir and a second valve are connected in sequence. The low-temperature side of the medium-temperature heat exchanger, a medium-temperature heat reservoir, a third valve, the high-temperature side of the medium-temperature regenerator, a medium-temperature cold reservoir and a fourth valve are connected in sequence.

  • Patent number: 10837321
    Abstract: An efficiency evaluation method of an RCAES system is disclosed, and the method includes calculating electric energy charged by an electric power system in a compression process, calculating electric energy discharged to the electric power system in an expansion process, and calculating a ratio of the electric energy discharged in the expansion process to that charged in the compression process, and taking the ratio as an efficiency of the whole RCAES system; wherein gas in operation is ideal gas, air mass flow rates in the compression and expansion processes are known and constant in operation, an isothermal model is adopted for the CASV of which the temperature is the same with ambient circumstances, and the temperature and pressure of compressed air after throttling become constant. A corresponding system is also disclosed.
