Each 1 MW/2 MWh energy storage container includes two sets of 500 kW PCS, 2 MWh battery and corresponding battery management system. In order to simulate various situations, this paper assumes that PCS units 1–100 are divided into 5 groups, every 20 is a group.
Battery energy storage connects to DC-DC converter. DC-DC converter and solar are connected on common DC bus on the PCS. Energy Management System or EMS is responsible to provide seamless integration of DC coupled energy storage and solar. Typical DC-DC converter sizes range from 250kW to 525kW.
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
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 .
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
