The supply of electricity required by the CAES unit for the storage of compressed air energy is done by the wind farm, which is responsible for supplying the energy of the GT to generate electricity during peak consumption. The use of the CAES unit is to increase the production capacity of the system and for peak consumption time.
Adiabatic Compressed Air Energy Storage (A-CAES) has been proposed to eliminate this problem [12].
