AI Customer ServiceThe energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
Secondly, the optimization goal is to maximize the annual net income of the energy storage system and minimize the cost of electricity per kilowatt-hour, and the key operating status is used as the constraint condition to establish an energy storage optimization configuration model.
