The three quantities are related as follows: Duration = Energy Storage Capacity / Power Rating. Suppose that your utility has installed a battery with a power rating of 10 MW and an energy capacity of 40 MWh. Using the above equation, we can conclude that the battery has a duration of 4 hours: Duration = 40 MWh / 10 MW = 4 hours.
Optimal sizing and allocation of battery energy storage systems
Usually, battery designers calculate the percentage of the capacity fade for a fixed current magnitude during different experiments, but in power systems, the magnitude of the supplied current varies continuously owing to the variations in the loads. For this reason, we use the capacity fade at the maximum current supplied by the battery.
How do you calculate the capacity of a battery energy storage system
