Analysis and Suggestions on the Architecture of New Distribution System IoT

The new power distribution system is an important part of building a new power system and promoting the realization of the “double carbon” goal. The massive access of distributed power generation, distributed energy storage and new load makes the distribution system appear new features such as diversified power supply, interactive power consumption, electronic power, intelligent equipment and digital management. The industrial control technology system supports the current real-time and low-frequency local acquisition of the main network and the distribution network, but with the access of massive equipment, it gradually fails to meet the perception requirements. This paper analyzes the architecture of the Internet of Things applicable to the new distribution system based on the technical path of the State Grid, China Southern Power Grid and related enterprises, and integrates cloud computing, high-speed network communication, network security, big data processing and other technical applications, It has the features of supporting massive terminal device access, device self-description supporting plug and play, terminal batch remote operation and maintenance, and flexible business expansion, and can effectively support million-level concurrent and million-level terminal access and management.
