Therefore, the base station energy storage can be used as FR resources and maintain the stability of the power system. The base station is the physical foundation for the popularity of 5G networks. 5G base stations distribute densely in cities.
Although the power output of a single base station storage is limited, the combined regulation of large-scale base stations can have a significant meaning. Therefore, the base station energy storage can be used as FR resources and maintain the stability of the power system.
The structure of base station provides conditions for energy storage to assist in power system frequency regulation. Although the power output of a single base station storage is limited, the combined regulation of large-scale base stations can have a significant meaning.
Integrating distributed PV with base stations can not only reduce the energy demand of the base station on the power grid and decrease carbon emissions, but also effectively reduce the fluctuation of PV through inherent load and energy storage of the energy storage system.
In [ 20 ], the energy saving strategy of base station is proposed considering the variability and complementarity of base station communication loads. This strategy helps the power system to cut peaks and fill valleys while reducing base station operating costs.
The energy storage batteries are the main resource of FR in the base station in this paper. Energy storage batteries are dispatched to realize the auxiliary FR of the power system by changing the energy supply mode of the base station.
