Battery Energy Storage Station Frequency Regulation Strategy The large-scale energy storage power station is composed of thousands of single batteries in series and parallel, and the power distribution of each battery pack is the key to the coordinated control of the entire station.
In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
Hence, the power of the battery energy storage station can be used for power compensation in the initial stage of system power shortage. If the power provided by the battery energy storage station is insufficient, the frequency regulation power required by the conventional thermal power unit is as follows :
According to the calculation, the power and capacity of the battery energy storage stations B1 and B2 with the same frequency regulation capability as the synchronous generator G7 and G8 are about 30 MW/4 MWh and 40 MW/5 MWh, respectively . 5.2. Simulation Calculation Analysis
Aiming at the problems of low climbing rate and slow frequency response of thermal power units, this paper proposes a method and idea of using large-scale energy storage battery to respond to the frequency change of grid system and constructs a control strategy and scheme for energy storage to coordinate thermal power frequency regulation.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
