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.
Current research on energy storage control strategies primarily focuses on whether energy storage systems participate in frequency regulation independently or in coordination with wind farms and photovoltaic power plants .
With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
Therefore, it is necessary to introduce new frequency regulation methods to enhance frequency support for the power system. Battery Energy Storage Systems (BESS) have become a hot research topic in participating in primary frequency regulation coordination control [3, 4, 5, 6].
Key research gaps are identified, and future directions are outlined to promote more adaptive, control-oriented use of ESSs under high RES penetration. This review concludes that
