Research on Key Technologies and Typical Configuration of Low-Voltage Distribution Network Perception System in the New Power System

As electricity substitution progresses, people's requirements for power grids are rising. The low -voltage distribution network is at the end of the power grid and directly connects with the power users. The idea of Power Distribution Internet of Things was proposed , which perception system construction is the critical part. This paper first outlines the Power Distribution Internet of Things architecture, then emphasizes three key technologies: edge computing, plug - and - play, and cloud - edge - terminal coordination. Three typical perception system configurations for distribution network are proposed according to the sides of distribution transformer, power line, and distributed PV connection. At last, this paper analyzes typical application scenarios.
