A battery energy storage system (BESS) plays a crucial role in the proper operation of a microgrid. Larger the size of the BESS, smaller is the microgrid operating cost, but higher is the BESS''s capital cost.

Optimizing the size of the energy storage system (ESS) can ensure the sustainable, resilient, and economic operation of the MG. Thus, key features of the optimal ESS, including methods and algorithms of ESS sizing, power quality, reliability, connection mode, and public policy enforcement for low-carbon emission, must be identified.
The capacity of a battery is typically measured in megawatt-hours (MWh) or kilowatt-hours (kWh), and it represents the total amount of energy that can be stored in the battery. The duration of a battery, on the other hand, is the length of time that a battery can be discharged at its power rating. This can be calculated by dividing the energy
The current market for grid-scale battery storage in the United States and globally is dominated by lithium-ion chemistries (Figure 1).
