Recently, Hebei Mobile signed the 5G smart power project of Zhengding New Power System Demonstration Zone of the State Grid Shijiazhuang Power Supply Company. The project is the first smart power application scenario in Hebei province to realize 5G "RB resource reservation", reserving special resources for fixed users through 5G network slice management to achieve the goal of ensuring stable user rate.

With the Zhengding County’s photovoltaic development and the construction of a new power system demonstration county, the project jointly promotes the pilot application of 5G technology in rooftop distributed photovoltaic, and adopts the exclusive mode coverage of mobile 5G network to reserve RB resources for 5G fixed users in the region. According to the digitalization requirements of the new power system, relying on 5G communication technology, information data such as photovoltaic inverters, intelligent switches for distribution and transformation, low-voltage flexible interconnection, and mobile energy storage are collected at high speed, the regulation strategy distribution of the main station is achieved and all kinds of equipment are regulated in a short time to achieve the flexible interconnection effect of the main station grid, and to ensure the safe operation of the distribution network under the large-scale absorption of photovoltaic energy in the whole county.

The 5G "RB resource reservation" will be applied in 12 types of application scenarios, such as power generation, transmission, transformation, distribution and consumption, which can meet the requirements of safe and reliable isolation of power grids by regions, steadily promote the large-scale application of 5G bearing distributed power regulation business, push forward the integration of 5G technology and photovoltaic development and new power systems, and help the efficient, safe and intelligent adaptation of 5G networks and power systems, and accelerate the integrated development of 5G + smart grid.
