The main task of the power grid is to convert unused energy into stability and reliability, and one of most effective measures to do this is to set up a transfer station to connect production and consumption [2].One such large-scale energy storage technology is compressed air energy storage (CAES), which plays an important role in supplying
Any CAES system is charged by using electricity to drive air compressors, resulting in compressed air and heat. In DCAES, the heat is extracted by using heat exchangers (HEX) and dissipated (being of low grade and therefore of low value), whereas the pressurized air is stored in a dedicated pressure vessel, herein referred to as the
The air is compressed using surplus energy and stores the energy in the form of compressed air. When energy demand exceeds supply, the air is released and heated to drive an expansion turbine to generate electricity. CAES systems in operation in Germany and the United States are both using salt domes with volumes of several 1 Mm
Compressed-air energy storage is a cost-effective, environmentally sound technology used to store electrical energy in the form of high-pressure air.
