The supply and demand side structure in new power system has undergone profound changes with the large-scale development of 5G base stations.Combined with the advanced technologies such as virtual power plants,the technology and application of adjustable resource aggregation in distributed 5G base station based on virtual power plants is studied in this paper.Based on demand side response,the intelligent selection of 5G base station energy-saving strategies,the automatic parameter configuration and effect evaluation,and the remote control technology are also studied to achieve the"dual optimization goal"of comprehensive energy-saving efficiency and operational efficiency.Adjustable loads such as 5G base station backup batteries are aggregated to form a"virtual power plant",in which the base station can be integrated,coordinated and optimized through regulation and be externally equivalent to controllable power supply to participate in grid demand response in order to support the construction of new power system.By using 5G+slicing technology,real-time monitoring of adjustable resources in 5G base station can be achieved,which includes the monitoring of device parameters such as power switch status and battery status,in order to adjust response resources in real time.About 445265G residential areas have been opened in Guangxi,saving 22.82 million kilowatt hours of electricity,equivalent to 17.63 million Yuan,which effectively supports the demand response capacity construction of Guangxi power grid company and assists the peak and valley load shifting of the power grid.At the same time,it can also effectively assist the energy conservation and emission reduction of 5G base stations.
