Zusammenfassung:The invention discloses a buoyancy feedback type hydraulic constant-pressure energy storage and release system and method. The bottom of an air storage tank is connected with a water surface floatingplatform by using a cable to bypass a fixed pulley, and when the system stores and releases air, the buoyancy feedback effect of the water surface floating platform can ensure that the air pressure inthe air storage tank is constant. The length of the cable is adjusted through a motor to adjust the working depth of the air storage tank, so that the working pressure of the system is set. In the power utilization valley period, the system drives the motor-generator through the electric energy of the power grid and drives the multi-stage air compressor to work, and the multi-stage air compressorcompresses the high-pressure air into the constant-pressure air storage tank; and in the power utilization peak period, the high-pressure air in the constant-pressure air storage tank is released, the high-pressure air expands
