Abstract: This paper mainly introduces the typical application scenarios of power business based on 5G power virtual private network. Based on the 5G public network power application technology framework, it matches the three application scenarios of 5G such as network low latency, large bandwidth, and massive connection, and summarizes 5 types of typical power communication application scenarios, including load control, distribution automation, intelligent inspection, distributed energy resource storage and power consumption information collection, and proposes the corresponding 5G power business scenarios communication technology and security solutions, meanwhile the corresponding work of 5G power business application scenarios in Zhejiang Province is carried out to verify the performance of power business scenarios in transmission delay, security and reliability, fast response, etc. Finally, the economic and social benefits of the system are expounded.
