Application of 5G private network based on quantum communication technology in smart grid

Abstract

The fifth generation mobile communication (5G) has the advantages of high bandwidth, low time delay and low power consumption, and it can play an important role in all aspects of power transmission, substation, power distribution and electricity consumption, effectively making up for the disadvantages of traditional optical fiber communication and profoundly transforming the power communication network. However, the information security problems brought by the application of 5G technology are gradually becoming prominent. Based on this, a quantum key distribution strategy based on the quality of service (QoS) is proposed to improve the confidentiality of 5G electric power private network application scheme. Finally, the feasibility of quantum communication application in power dispatching system is verified. The test results show that the service quality of 5G private network meets the communication requirements of power grid services, the actual transmission delay of the power grid simulation dispatching data is about 1s, and there is no packet loss.

“…The security and performance of future communication networks, especially 5G networks, can be greatly improved by using QKD technology. Xiang et al [8] proposed a 5G private network based on quantum communication technology for smart grid applications. They pointed out the information security challenges posed by 5G, and proposed a QKD strategy based on the Quality of Service (QoS) to improve the confidentiality of the 5G private power network application scheme.…”
