Charge-discharge cycles

Definition

Charge-discharge cycles refer to the processes in which energy storage systems are charged with energy and then later discharged to release that stored energy for use. These cycles are crucial for managing the energy produced by renewable sources, such as tidal and wave energy, ensuring that energy can be stored when production exceeds demand and released when needed, thus enhancing reliability and efficiency.
