Abstract
A combined gas-liquid two-phase energy storage and power generation system includes a compressed gas storage unit, a first gas pipeline, a liquid piston device, a hydraulic energy conversion unit and a first pumped power generation unit. The combined gas-liquid two-phase energy storage and power generation system connects the liquid piston device and a first port group of the hydraulic energy conversion unit and receives/outputs the hydraulic potential from/to the first port group, and connects the first pumped power generation unit with the second port group of the hydraulic energy conversion unit and receives/outputs the hydraulic potential from/to the second port group.
