Claim 12:
13. The system according to claim 12, further comprising a cryogenic energy compensation subsystem, wherein the cryogenic energy compensation subsystem comprises a cryogenic expansion unit and a mixer, the other branch of the two split branches of supercritical air split by the proportional adjustment device of the supercritical liquefaction subsystem enters the cryogenic energy compensation flow passage in the liquefaction cold box of the staged cryogenic storage subsystem and cools, and then enters the cryogenic expansion unit to expand and cools further, and mixes with cryogenic air at a gas-side outlet of the gas-liquid separator in the mixer, the cryogenic energy is recovered by the cryogenic energy recovery flow passage in the liquefaction cold box of the staged cryogenic storage subsystem, and then the air returns to the inlet of the multistage compressor or returns to gas paths between the stages of the multistage compressor.
