The realization of the carbon peaking and carbon neutrality goal and the construction of new type power system is a widespread and profound system transformation. With the large-scale decentralized access of new energy，the complexity and control difficulty of the power grid have greatly increased，and higher requirements have been put forward for the power Internet of Things（IoT），such as wide coverage，high speed，low latency，and high reliability. Based on the collection，perception，processing and application of power grid information，the power IoT has built an architecture with the cloud master station as the platform，the acquisition terminal as the core of edge computing，and smart switches，distributed photovoltaic，energy meters and other end devices，to realize the comprehensive perception of new energy and flexible loads，and promote the digital and green development of the power system. This article focuses on analyzing the technical characteristics of power line carrier communication，high-speed dual mode communication，power 5G remote communication，and power chips based on the communication requirements of the power IoT. It showcases the demonstration applications of power IoT technology in scenarios such as electricity information collection，intelligent energy consumption，orderly charging，and photovoltaic monitoring.
