Design and Optimization of a Charging Station for Electric Vehicles based on Compressed Air Energy Storage

Abstract The diffusion of electric vehicles (EVs) is strongly limited by charging issues, among which there is their potential impact on electricity grid network. This paper analyzes the possible recourse to recharging stations based on compressed air energy storage (CAES) system with volumetric compressor and expander as a solution for reducing the impact of recharging stations on power system operation. A model for design and optimization of a compressed air energy storage (CAES) system with volumetric compressor and expander is presented in the paper. The results of an optimization analysis based on the application of Dynamic Programming are presented and discussed, evidencing the potential benefits of this solution.
