If the material is not always stored in the same vessel, but moved from one vessel to another during charging/discharging, the components do not contribute to the energy storage capacity of the system (i.e. two tank molten salt storage).
Energy storage systems have the advantages of balancing grid load, regulating power fluctuations, emergency standby, and supporting renewable energy integration
As renewable energy penetration increases, maintaining grid frequency stability becomes more challenging due to reduced system inertia. This paper proposes an analytical control strategy that enables distributed energy resources (DERs) to provide inertial and primary frequency support.
Response Mode Incorporating SOC Energy storage devices are capable of significantly improving the system’s equivalent inertia and damping via virtual inertia and droop control, thereby improving grid frequency response performance. However, in real-world scenarios, the capacity of energy storage systems is subject to inherent limitations.
In this study, the SOC is computed by integrating the output power of the energy storage system over time and subtracting the accumulated energy from the initial SOC value. This approach allows real-time tracking of the energy state and reflects the dynamic charging and discharging behavior of the system.
Energy storage systems, including VPPs, provide primary regulations according to their local frequency deviations. The droop coefficients K s t o decide the magnitudes of energy storage’s power responses against frequency deviations. Thus, it is significant to set proper energy storage droop coefficients considering various operating modes.
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 .
For example, virtual energy storage systems provide frequency regulations by coordinating demand responses and flywheels . Distributed energy resources are aggregated to provide contingency frequency support via the virtual power plant technology , , .
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.
