Recently, the first working conference of the Energy Internet Industry Group in 2021 and the 5G+ Energy Internet Industry Seminar organized by 5GDNA (5G Deterministic Network Industry Alliance) was held. Li Kun, deputy director of the Internet Department of State Grid Qingdao Power Supply Company, said that Qingdao Power Supply Company explored 5G+ differential protection, 5G+ power line monitoring, 5G+ distribution network automation, 5G+ substation inspection, 5G+ smart material management and control, 5G+ peak cutting and valley filling, 5G+ mobile office and other applications.
In recent years, in order to reduce the intensity of transmission line inspection work, State Grid Qingdao Power Supply Company has begun to promote large-scale line inspection operations without large machines. With the gradual implementation of this model, some problems have gradually emerged, mainly "difficulty in operation." "Difficult to pass back" and "difficult to analyze" issues. The precise navigation based on the electric Beidou ground-enhanced base station can achieve real-time centimeter-level accuracy. Through trajectory planning, the drone will automatically fly during the entire inspection process.
State Grid Qingdao Power Supply Company has realized the first domestic research and development of a 5G SA network data high-speed transmission module that can be carried by drones, realizing the real-time return of drone videos and images on the 5G slice network, and reducing the overall time of data dump operations by 98 %, to ensure the safety of inspection data transmission.
In terms of 5G+ precision load control, the State Grid Qingdao Power Supply Company has implemented a precision load control system that focuses on solving the problems of rapid frequency drop in the initial stage of grid failure, excessive power flow of main roads, excess power of inter-provincial tie lines, and insufficient power grid spinning reserve.
At the same time, the whole province of Shandong has begun to build a 5G power slice network to build a slice of the province's production control area. It is ready to carry out local power plant access, distributed power access (assisted load forecasting); electric vehicle access (assisted source network load flexible dispatch). In the Jiaozhou Shanghe Demonstration Zone, expand the pilot distribution network differential protection, expand the application of scene automation, and carry out 5G communication experiments such as local power plants and distributed power sources.
"To promote the development of the industry, it is necessary to introduce charging standards as soon as possible. At present, the charging standards of the ToB business model are still unclear. Although the three major operators have launched virtual private networks, shared private networks, and exclusive private networks, three types of business models are lacking. Operators’ headquarters-level charging guidelines are difficult to negotiate on tariffs during the actual commercialization process. It is recommended that operators issue charging guidelines as soon as possible."Kun suggested
