| Abstract:In the context of integration of high penetration renewable energy, electricity market reforms, and internet plus smart energy, massive data support is needed and the physical, commercial, and information interconnections of power (energy) grids must be strengthened. A key step is to construct the Ubiquitous Power Internet of Things (UPIoT), and realize the connections among people and things in the power system at anytime and anywhere. The development background and concept of UPIoT and the major Low Power Wide Area Network (LPWAN) technologies are introduced at first. Then the architecture and performance of LPWAN based UPIoT are elaborated by taking the LoRa IoT solution as an example. Finally, the application prospect of UPIoT is discussed, and the special problems of UPIoT, namely low-voltage power line carrier communication (PLC) and signal processing in strong electromagnetic interference environment are pointed out, which need to be further studied. This work is supported by National Key Research and Development Program of China (No. 2016YFB0900100). |
