In the process of energy storage participating in frequency regulation, the dynamic control of energy storage SOC can effectively suppress SOC fluctuation and fully use the idle state of energy storage to fine-tune SOC so that the SOC can be adaptively restored to the reference value.
At the initial stage of regulation, each energy storage unit is charged/discharged as much as possible to make its SOC tend to be consistent with the leading battery pack. When the SOC of each energy storage unit is consistent, its output keeps the same as that of the leading battery pack to track the target value.
