Supercapacitors can effectively enhance the rotational reserve capacity of the power grid in substation frequency regulation. Supercapacitors can quickly release energy in the power grid, solving problems such as frequency instability and voltage drops in large disturbances. The multifunctional supercapacitor energy storage device has the advantages of compact structure and small footprint, which can fully utilize the efficiency of scattered idle space resources in substations.
