When the system frequency fluctuates, power plants first perform primary and secondary frequency regulation, while the energy storage system assists by providing additional power support when the power plants' capacity is insufficient to stabilize the frequency. . Secondary frequency regulation is essential for maintaining power system frequency stability, especially with the growing integration of renewable energy. The intermittent and unpredictable nature of renewable energy increases grid frequency fluctuations, while traditional thermal power units. . A two-layer control strategy for the participation of multiple battery energy storage systems in the secondary frequency regulation of the grid is proposed to address the frequency fluctuation problem caused by the power dynamic imbalance between the power system and load when a large number of new. . Primary and secondary frequency regulation play a crucial role in maintaining frequency stability in the system. It works through the turbine governor system, which rapidly adjusts output power—usually within seconds. However, this adjustment is proportional and. . The methods for controlling the frequency of the power grid include primary frequency regulation, secondary frequency regulation, high-frequency switching, automatic low-frequency load shedding, unit low-frequency self starting, load control, and DC modulation. The power grid must have appropriate. .
