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.
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.
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 results of the study show that the proposed battery frequency regulation control strategies can quickly respond to system frequency changes at the beginning of grid system frequency fluctuations, which improves the stability of the new power system frequency including battery energy storage.
In literature , the frequency regulation model of a large-scale interconnected power system including battery energy storage, and flywheel energy storage system was studied. The effect of communication delay on frequency regulation control and the battery is analyzed by building a detailed model of the battery energy storage system.
The grid system operates normally and its initial frequency is 49.97 Hz when the BESS is not connected to the system. In addition, it is assumed that the battery energy storage has sufficient charge in the simulation process.
