Compressed Air Energy Storage: Optimal Performance and Techno-Economical Indices

A thermodynamic and techno-economical analysis of a Compressed Air Energy Storage system subjected to an exogenous periodic electricity price function of the interconnection is presented. The fundamental parameters affecting the thermodynamic performance and the techno-economical cost-benefit indices are identified and corresponding optimisation problems are formulated. The results of the analysis permit to obtain the optimal values of the fundamental plant parameters to be used in the design process.
