Abstract:

Compressed air energy storage(CAES) is an energy storage technology that uses compressors and gas turbines to realize the conversion between air potential energy and heat energy.Since CAES can regulate and distribute the"source"and "load"across time and space,the technology has become increasingly important as high-proportion intermittent renewable energy is connected to the power grid.Energy storage systems are classified from three aspects:configuration of heat sources,adiabaticity and configuration of heat storage devices.Among them,CAES has three main application modes, diabatic CAES without heat source,diabatic CAES with heat source and adiabatic CAES with heat storage system.Analyzed from multi-energy coupling modes,CAES systems’coupling with gas turbines,internal combustion engines and renewable energy systems are introduced,respectively. Furthermore,various integration forms of CAES technology and its coupling with coal-fired power plants are analyzed,which are compared with traditional CAES,adiabatic CAES,isothermal CAES and heat storage CAES technology from the energy storage scale,advantages and disadvantages.The study is expected to provide reference for the application of CAES technology.
