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.
The application of energy storage in power grid frequency regulation services is close to commercial operation . In recent years, electrochemical energy storage has developed quickly and its scale has grown rapidly, . Battery energy storage is widely used in power generation, transmission, distribution and utilization of power system .
In recent years, the use of large-scale energy storage power supply to participate in power grid frequency regulation has been widely concerned. The charge and discharge cycle of frequency regulation is in the order of seconds to minutes.
Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours.
