An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
Battery energy storage systems are generally designed to be able to output at their full rated power for several hours. Battery storage can be used for short-term peak power and ancillary services, such as providing operating reserve and frequency control to minimize the chance of power outages.
As of the end of 2022, the total nameplate power capacity of operational utility-scale battery energy storage systems (BESSs) in the United States was 8,842 MW and the total energy capacity was 11,105 MWh. Most of the BESS power capacity that was operational in 2022 was installed after 2014, and about 4,807 MW was installed in 2022 alone.
Several important parameters describe the behaviors of battery energy storage systems. Capacity [Ah]: The amount of electric charge the system can deliver to the connected load while maintaining acceptable voltage.
By placing energy storage systems where they are most needed, grid operators can ensure more efficient voltage regulation, especially in areas with high load density or regions far from traditional generation sources. The Power Conversion System (PCS) within the BESS plays a crucial role in providing voltage support.
In the quest for a resilient and efficient power grid, Battery Energy Storage Systems (BESS) have emerged as a transformative solution. This technical article explores the diverse applications of BESS within the grid, highlighting the critical technical considerations that enable these systems to enhance overall grid performance and reliability.
