Key technologies of ubiquitous power Internet of Things-aided smart grid

Ubiquitous Internet of Things refers to the interconnection and interaction of information at any time, any place, anyone, and anything. The ubiquitous power Internet of Things (UPIoT) refers to the application of ubiquitous IoT technology in power systems. Its implementation has the following advantages for power grids: connecting the devices that should have been connected; sharing the data that should have been shared, and the value of data can be used more efficiently. Different from the smart grid, which is designed to build a multienergy integrated network and distributed management intelligent system with intelligent judgment and adaptive adjustment ability, the essence of UPIoT is to realize holistic perception and ubiquitous connection of energy. This paper introduces a technical architecture proposed by China State Grid Corporation, based on which the key communication and information technologies of UPIoT are analyzed in detail from the four elements of UPIoT. The challenges of implementing UPIoT are also introduced.
