Abstract
In 2019, State Grid Corporation of China (SGCC) proposed the strategic goal of building and developing a strong smart power grid and ubiquitous power Internet of things. Smart power grid and ubiquitous power Internet of things involve massive information interaction in power system, which cannot be separated from the support of advanced communication technology. 5G communication system integrates advanced network technology, and has the advantages of high resource utilization, fast transmission rate and high spectrum utilization. Compared with existing 4G communication systems, it has a great improvement in user experience, transmission delay and coverage. In this paper, we take the application of 5G communication system in power system as the main research content, discuss various wireless communication application scenarios in power system, and analyze the feasibility of 5G communication to support the ubiquitous power Internet of things construction in terms of key technologies and application costs of 5G communication. However, the energy consumption and security of 5G communication system are still major factors that limit its application in the ubiquitous power Internet of things, and these problems need to be fully paid attention to by researchers.
