Abstract

The invention discloses a compressed air energy storage system, in particular to a compressed air energy storage system for an electric power system. The compressed air energy storage system disclosed by the invention has reasonable structure, flexible layout, high energy conversion efficiency, good economical efficiency and peakload regulation performance, rapid startup, safety and reliability. The compressed air energy storage system applying the invention can be used for despicking and valley filling of the electric power system, energy storage of renewable energy source and power supply when the renewable energy source is in supply intermission or in shortage in an electric network, and can be used as an emergency power station, an energy accumulator of distributed energy resource and other equipment for electric power energy storage.

Description

Compressed Air Energy Storage System technical field The invention relates to the technical field of energy storage, and relates to a compressed air energy storage system, in particular to a compressed air energy storage system used in a power system. Background technique The compressed air energy storage system uses electric energy to compress air and store it in underground or above-ground chambers. When electric energy needs to be output, the compressed air is released, heated and burned to drive turbines to generate electricity. In the People's Republic of China, there is no compressed air energy storage power station put into operation so far, and no design method for compressed air energy storage power station has been published. Contents of the invention The invention provides a compressed air energy storage system, which can be used in a compressed air energy storage power station to improve the efficiency of a power grid. In order to achieve the above object,...
