The concept of CAES is derived from the gas-turbine cycle, in which the compressor (CMP) and turbine operate separately. During charging, air is compressed and stored with additional electricity, and the compression heat is stored in a thermal energy storage (TES) unit for future use.
When running an air compressor continuously, it is essential to consider the risk of overheating and overloading. Overheating can occur when the compressor is operated for extended periods without allowing time for cooling. This can lead to potential damage to the motor and other components of the compressor.
