Under the development trend of power industry with energy Internet as the core, with the update of information technologies such as intelligent devices, mobile communication technology and cloud computing, the application of Internet of things (IOT) in power industry has developed from the concept of specific link service to the application of large-scale market. The core of the next power Internet of things construction is to build an open IOT management platform to realize the ubiquitous access of massive devices, the deep sharing of cross-professional data, business integration, and the provision of precise user services. Based on this, an industrial alliance will be formed and a power industry ecosystem with power grid enterprises as the core will be established. At present, the application of power Internet of things in China is still in the primary stage of research and application. The research on what the IOT management platform should manage and the interaction technology between the IOT management platform and edge agents is still in the stage of exploration and pilot. This paper mainly studies the cloud-edge interaction technology, including the interaction object, process and message format. Then it formulates a set of cloud-edge format specifications to meet the requirements of the platform’s own management and business system message transmission, so as to provide reference for the cloud-edge interaction of power Internet of things.
