The ES-toolbox demonstration is shown in the below video. The video presents an example of a whole CAES simulation model in the ES-toolbox. It has an asynchronous motor that drives a three-stage piston compressor for CAES charging process. On the other hand, it has a scroll expander that drives a PM synchronous generator for CAES discharging process. It also contains an adiabatic compressed air storage tank module that calculates the air pressure and temperature inside the tank.
