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.
The fuzzy theory approach was used to study the frequency regulation strategy of battery energy storage in the literature , and an economic efficiency model for frequency regulation of battery energy storage was also established. Literature proposes a method for fast frequency regulation of battery based on the amplitude phase-locked loop.
The hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
. The value of energy storage systems (ESS) to provide fast frequency response has been more and more recognized. Although the development of energy storage technologies has made ESSs technically feasible to be integrated in larger scale with required performance
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 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.
