Case Overview: China's largest 5G smart grid pilot network, the first phase focuses on four major topics: intelligent distributed power distribution automation, power slicing and security isolation, substation operation monitoring, and intelligent peak shaving and valley filling.

Case Description:

In August 2019, China Telecom Qingdao, State Grid Qingdao, and Huawei signed a strategic cooperation agreement on 5G. In October, the three parties built the largest 5G smart grid experimental network in Qingdao China. In the first phase, two sets of MECs dedicated for power supply have been deployed in four application demonstration areas, including Laoshan Jinjialing, Olympic Sailing Center, power scheduling building, and ancient town entrance on the west coast. The number of base stations exceeds 30. In addition, they have continuously carried out a series of innovative practices and field tests on multi-scenario power slicing, including the industry's first 5G-based intelligent distributed feeder automation and 5G longitudinal differential protection slicing tests, in addition, it is the first to use the 5G network slicing-based transformer substation power distribution sensing system to provide 5G+power protection services for the 2019 Qingdao Summit of Multinational Corporation leaders.

Thanks to the joint efforts of the three parties, the 5G+Smart Grid project in Qingdao has achieved fruitful results. In November 2019, the project won the first prize of the Shandong Mobile Internet and 5G Application Innovation Technology Contest. As a typical industry case, this case was included in the 5G Deterministic Networking Industry White Paper jointly released by CAICT, the 5GDNA Alliance, the three major carriers, and Huawei in February 2020.

In February 2020, this project was successfully included in the GSMA 5G Application Cases powered by 5G SA (the only industrial energy case).
