This paper proposes a comprehensive control strategy for a battery energy storage system (BESS) participating in primary frequency modulation (FM) while considering the state of charge (SOC) recovery.
The previous energy storage systems involved in secondary frequency modulation control strategy research mostly used the energy storage system as a small-capacity traditional frequency modulation unit for power signal distribution.
Li Cuiping et al. used a battery energy storage system to assist in the frequency modulation of thermal power units, significantly improving the frequency modulation effect, smoothing the unit output power and reducing unit wear.
