Energy storage control
Determining an energy storage device plan includes determining a benefit gradient associated with charging or discharging of an energy storage. It further includes determining, using an energy storage lifetime model, a cost gradient associated with a degradation of the energy storage due to charging or discharging. It further includes applying a threshold to the benefit gradient and the cost gradient. It further includes facilitating charging or discharging of the energy storage based at least in part on the threshold being met or exceeded.
