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. 1 Batteries are one of the most common forms of electrical energy storage. The first battery, Volta's cell, was developed in 1800. pioneered large-scale energy storage with the. . Mechanical ESS utilize different types of mechanical energy as the medium to store and release electricity according to the demand of power systems. Energy can be stored in a variety of ways, including: Pumped. . The traditional power system is a continuous operation system that integrates power production, transmission, distribution, and consumption.

Numerous studies have investigated control strategies that enable distributed energy resources (DERs), such as wind turbines, photovoltaic systems, and energy storage, to contribute to primary frequency regulation. A reduced second-order model is developed based on aggregation theory to simplify the multi-machine system and facilitate time-domain frequency. . To mitigate the system frequency fluctuations induced by the integration of a large amount of renewable energy sources into the grid, a novel ESS participation strategy for primary frequency regulation considering the State of Charge (SOC) is proposed. This strategy integrates virtual inertia. .
