OPTIMUM COUPLING OF THERMAL ENERGY STORAGE AND POWER CYCLES FOR CARNOT BATTERIES

To enable the widespread exploitation of intermittent, low-cost, and non-dispatchable renewable energy technologies, energy storage plays a key role in providing the required flexibility. In the spectrum of energy storage systems, one out of a few geographically independent possibilities is the storage of electricity into heat, so-called Carnot batteries. For thermal-to-electricity reconversion, depending on the operating energy storage temperatures, conventional or advanced
