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.
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.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
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 :
In addition, by leveraging the scaling benefits of power stations, the investment cost per unit of energy storage can be reduced to a value lower than that of the user’s investment for the distributed energy storage system, thereby reducing the total construction cost of energy storage power stations and shortening the investment payback period.
