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.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Authors to whom correspondence should be addressed. In standalone microgrids, the Battery Energy Storage System (BESS) is a popular energy storage technology. Because of renewable energy generation sources such as PV and Wind Turbine (WT), the output power of a microgrid varies greatly, which can reduce the BESS lifetime.
It starts by obtaining the input power of WT, PV, and load, and then calculating the rated power and energy capacity of the battery. Then, it estimates the BESS lifetime using the BESS model and obtains the objective function’s value. If is minimal, the calculation ends.
Integrating distributed PV with base stations can not only reduce the energy demand of the base station on the power grid and decrease carbon emissions, but also effectively reduce the fluctuation of PV through inherent load and energy storage of the energy storage system.
