Compressed air energy storage (CAES) technology has received widespread attention due to its advantages of large scale, low cost and less pollution. However, only mechanical and thermal dynamics are considered in the current dynamic models of the CAES system. The modeling approaches are relatively homogeneous.
Compared with other energy storage technologies, CAES is proven to be a clean and sustainable type of energy storage with the unique features of high capacity and long-duration of the storage. The intention of this paper is to model and analyse a small scale compressed air storage system useful for standalone and micro-grid applications.
To overcome such disadvantages Adiabatic Compressed Air Energy Storage (A-CAES) has been proposed. Instead of burning fuel, in A-CAES the heat generated by compression is stored in a Thermal Energy Storage (TES) and then used to heat air from the reservoir before it enters the turbines , .
It was found that an A-CAES efficiency in the range 60-70% is achievable when the TES system operates with a storage efficiency above 90%.. An accurate dynamic simulation model for compressed air energy storage (CAES) inside caverns has been developed. Huntorf gas turbine plant is taken as the case study to validate the model.
