The power grid company improves transmission efficiency by connecting or building wind farms, constructing grid-side energy storage, upgrading the grid, and assisting users in energy conservation, carbon offsetting, etc. to achieve zero carbon goals.
For integrating energy storage systems into a smart grid, the distributed control methods of ESS are also of vital importance. The study by [ 12] proposed a hierarchical approach for modeling and optimizing power loss in distributed energy storage systems in DC microgrids, aiming to reduce the losses in DC microgrids.
The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
User-side shared energy storage is composed of interconnection and mutual benefit of adjacent energy storage devices in the same area, so the power loss in the power interaction process can be ignored 17.
However, the disorderly management mode of user-side energy storage not only causes a waste of resources, but also brings hidden dangers to the safe operation of the power grid, such as stability, scheduling and operation, power quality and other problems.
As can be seen in Table 3, for the power type and application time scale of energy storage, the current application of energy storage in the power grid mainly focuses on power frequency active regulation, especially in rapid frequency regulation, peak shaving and valley filling, and new energy grid-connected operation.
