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 .
Relationship between unit regulation power of energy storage and SOC. The blue line represents the discharge power curve, indicating the reduction in power as the state of charge (SOC) decreases. The red line represents the charge power curve, showing the increase in power as SOC rises.
However, in real-world scenarios, the capacity of energy storage systems is subject to inherent limitations. Using the maximum droop coefficient in both charge and discharge modes during the initial frequency control phase can easily cause the SOC of the energy storage device to exceed its operational limits.
Proposing a flexible regulation scheme for energy storage systems involved in frequency control, and dynamically adjusting synthetic inertia and damping coefficients according to state of charge (SOC) levels.
