/PRCWT/September 22, 2023 Zhejiang - "Clear water and green mountains are golden hills and silver mountains". By taking advantage of the spring breeze of the 5G era, the green electric smart network has played the leading movement of the "double carbon" era, and Zhejiang has woven a highly resilient power grid with multiple integration, helping the Yangtze River Delta regional economic data and intelligence upgrade.
Zhejiang has been rich in the world since ancient times and is a rich place for the world. Today, Zhejiang economy still ranks among the forefront of the country. As a large economic province, Zhejiang's daily maximum electricity consumption exceeded 100 million kilowatts, the scale exceeded Germany, France and other developed countries, always testing the "source, network, load, storage" four aspects of the coordination ability, and the high proportion of foreign electricity, high proportion of clean energy, peak differential rate and other "three high" characteristics, making the contradiction of transformation and development increasingly prominent.
Shen Qiuquan, director of industrial energy industry at the important customer center of China Mobile Communications Group Zhejiang Co., LTD., said: "Under such an overall situation, how to strengthen the coordination of the source network load and storage of our power grid, build a highly flexible power grid, promote the construction of a new energy system, and prudently promote our dual carbon goal has become a topic. Using China Mobile's 5G soft and hard slicing mode, through core network sinking, wireless base station IP resource reservation and other technologies, it not only meets our requirements of wide power coverage, but also provides high security communication links, but also provides low latency and large bandwidth performance requirements, which is the best choice to solve the current power communication problem."
"The overall framework of our 5G power private network is mainly around one, two, three N, which specifically refers to a blueprint, two slices, three regions and N applications." Starting from 2021, we at State Grid Zhejiang Electric Power and China Mobile have started to cooperate in the construction of 5G+ smart power." State Grid Zhejiang Electric Power Co., Ltd. information and communication branch wireless communication management full-time Wang Xinjia said.
More than two years of exploration and practice, Zhejiang has built the country's largest 5G+ smart power landing application scenario, based on China Mobile's 5G power private network soft and hard slice combined with innovative applications, a total of 14 kinds of smart power application scenarios have been launched. At present, the 5G smart power private network covers 11 cities in the province, has more than 1,500 hard slice base stations, and 5G power terminal access exceeds 10,000, making 5G the optimal solution for the "last kilometer" of power communication.
Li Yang, communication engineer of State Grid Hangzhou Power Supply Company, said: "The original intelligent switch in Hangzhou does not have the remote control function, and it is necessary to switch the switch on the spot. Due to the limitation of the time limit of the protection level difference, it is difficult to achieve rapid and accurate isolation and preparation. The reliability of users' electricity consumption is affected. The distribution automation switch based on 5G communication technology is used to achieve remote control operation of regulators, improve power supply reliability, power supply quality, and distribution automation coverage. Improve the efficiency of troubleshooting and reduce the workload of relevant professionals." 5G soft slicing technology, with better bandwidth and security than 4G, and lower traffic charges, enables nearly 10,000 business terminals such as 5G distributed energy monitoring terminals, 5G drones, 5G inspection robots, 5G video surveillance, 5G security control, 5G smart material supply, and 5G energy data center terminals.
The combination of 5G soft and hard slicing technology, in the Pan-Asian Games area with the Qianjiang Century City Asian Games Stadium as the core, network-load interaction, multi-energy complementary, and six stations in one, to create the Pan-Asian Games "source network-load and storage" energy interconnection demonstration area.
Wang Xinjia said: "Relying on China Mobile's 5G smart power private network, State Grid Zhejiang Electric Power has achieved mass security access of second-level interruptable load terminals. More than 1,400 interruptible load control terminals have been built in the province, with a response capacity of more than 2 million kilowatts. So far, it has successfully cut off 1.3 million kilowatts of interruptible load to ensure the stable operation of the power grid. In addition, in terms of labor costs, operation and inspection costs, and reducing repeated expansion of generator sets, cumulative savings of 1.5 billion yuan and carbon emissions of 13.4 million tons were reduced."
"Through 5G innovation, we enable various applications of electricity, improve the absorption capacity of new energy in the grid, enhance the response capacity of the load side, promote the construction of a new power system, promote the clean and low-carbon energy transformation, and help achieve the dual-carbon goal." Shen Qiuquan said.
When the blood is fused, the body can thrive, when the energy is abundant, the economy will advance by leaps and bounds, the innovation trend led by 5G, the "double carbon" strategy enabled by 5G, the power of real integration with the future to lead the present, so that the dream can be illuminated into reality!
