The invention relates to the technical field of storing and releasing electric energy, in particular to an air-pushed oil energy storage system which comprises an energy storage system and a power generating system, wherein the energy storage system comprises a compressed air liquid-flow energy storage tank (4) and a compressed air tank (5); and the power generating system comprises an air hydraulic engine (7) and a power generator (10). After being compressed, air is introduced into the compression air tank (5) for directly driving hydraulic oil into the compressed air tank (5), so that hydraulic oil becomes liquid with pressure intensity. When voltage current fluctuates or is too low, high-pressure air and hydraulic oil with pressure intensity in the compressed air liquid-flow energy storage tank (4) are released, and the hydraulic oil with pressure intensity pushes the air hydraulic engine (7) to work, and the air hydraulic engine (7) drives the power generator (10) to generate power, so that power generating efficiency of the whole power generating system is improved.
Description
technical field [0001] The invention relates to the technical field of storing and releasing electric energy, in particular to an air-push oil energy storage system. Background technique [0002] Renewable energy power generation such as wind energy, solar energy and ocean energy is affected by seasonal, meteorological and geographical conditions, and has obvious discontinuity and instability. The emitted electric energy fluctuates greatly, and the adjustability is poor. At the same time, the power generation capacity of hydropower projects is sufficient during the wet season, but because the total power consumption is relatively fixed within a certain period of time, it has caused a large loss of electric energy and loss of equipment and line networks during the wet season. When too much power generation capacity is connected to the grid, the stability of the grid will be affected. In addition, the industrial tail gas has caused increasingly serious environmental problems...
