Abstract At present, power internet of things (PIoT) is a transitional form which represents development and innovation of the power industry towards the Energy Internet. It is facing a new era of digital transformation in the directions such as monitoring and management. Existing data transmission schemes are too weak to cope with the change. It is urgent to introduce advanced data transmission schemes as a digital forerunner to lead and improve the construction of PIoT. The 5th generation mobile networks (5G) is favored by all walks of life due to its advantages in performance indicators such as bandwidth, time delay, and transmission. In the future, 5G is also expected to be deeply integrated with the PIoT, in order to meet development challenges. Therefore, the article focused on the data transmission technologies in PIoT, firstly expounded the importance of data transmission in the process of building PIoT, analyzed the data transmission network among PIoT through combing the PIoT architecture, and divided the data transmission schemes’ application scenarios into three categories: collection, control, and power business information transmission. Then used the three categories as a basis to sort out and discuss the application status of the existing data transmission schemes in PIoT, and combining with the current digital transformation, analyzed the new demands of PIoT for data transmission schemes. Next, starting from the technical features of 5G technology itself, the authors analyzed its applicability in PIoT, and summarized 5G’s research status in PIoT. Finally, the authors pointed out challenges that 5G technology may meet when is applied into PIoT at future. What’s more, the trend that data transmission schemes will carry in PIoT was pointed out, which not only will carry extremely large amounts of diversified data information, but also will develop with an integrated communication architecture. The authors hope provide reference for the research and practice of PIoT.
