Compressed air energy storage applied to power grid belongs to

Compressed air energy storage applied to power grid belongs to energy type energy storage.

Compressed air energy storage refers to the energy storage mode in which electric energy is used for compressed air in the low power grid load period, and compressed air is released in the peak power grid load period to promote steam turbine power generation. The main forms are traditional compressed air energy storage system, compressed air energy storage system with heat storage device and liquid-gas compression energy storage system.

Since 1949 StalLaval proposed using compressed air to store energy, scholars at home and abroad have done a lot of research, and two large-scale traditional compressed air energy storage power stations have been put into operation in the world. 1978, the first commercial compressed air energy storage unit was born in Hentoff, Germany. 199 1 May, the second power station was put into operation in McIntosh, Alabama, USA.

Energy type energy storage

Energy-based energy storage technology is based on distributed energy technology, which converts electric energy into other energy modes through distributed energy storage units, thus realizing energy storage, distribution and conversion. In the conversion process, it can effectively reduce energy consumption, give full play to the advantages of energy storage devices, and reduce equipment investment and operating costs.

In addition, the energy type energy storage adopts multi-function mode, which supports the entity and grid power system, and can be used as instantaneous power support to provide the stability and security of the grid. At the same time, it also has good controllability, performance stability and energy-saving effect, so from the aspects of energy saving, emission reduction and utilization efficiency. Therefore, the energy revolution is bound to be accompanied by the progress of energy storage technology. Among them, energy storage is a technical approach, which can solve the challenges brought by the change of traditional energy environment, thus improving the availability of energy resources.
