Abstract

The invention discloses an air energy storage system and method. The air energy storage system comprises an air energy storage space, a pouring weight, a rubber air bag, a turbine and a compressor. When surplus electric energy drives the compressor to work through a compressor power source, air is injected into the rubber air bag through compression of the compressor, the pouring weight is gradually lifted, and energy reaches maximum till the pouring weight reaches the highest position; and when electric energy of a power grid needs to be supplemented by the energy storage system, a pressure regulating valve is opened, and the compressed air enters the turbine to push the turbine to do work. According to the air energy storage system and method, the form is simple, a novel air energy storage technology can more sufficiently utilize a storage space, large-scale energy storage can be effectively achieved, and the air energy storage system and method have the characteristics that the structure is simple, and implementation is easy, and can obtain obvious social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of large-scale energy storage, in particular to an air energy storage system and an energy storage method. Background technique [0002] With the development of the national economy, my country's electric power industry is developing rapidly. The development of solar energy, wind energy and other renewable energy generation technologies and smart grid technology has become an important means to alleviate environmental pollution and improve the quality of energy supply. [0003] However, renewable energy such as wind energy and solar energy is intermittent energy, and large-scale energy storage technology is a strategic technology to support the popularization of renewable energy, and it is also a key technical support for the development of smart grids. The currently developed large-scale energy storage technologies include: compressed air energy storage, pumped water storage, flywheel energy storage, etc. ...
