Overview of Digitalized Application Scenario of Low Voltage Distribution System Based on Intelligent Terminal

Under the guidance of the china carbon peaking and carbon neutrality goals, a large number of new power loads such as distributed power generation and electric vehicles are connected to the low-voltage distribution system, which poses new challenges to the operation and control of the low-voltage distribution system. With the continuous expansion of the application scope of key equipment in emerging distribution networks represented by intelligent terminals, new-generation business master stations, low-voltage intelligent switches, grid-connected inverters, etc., various emerging technologies and the power industry further intersect, so that the specific realization of the key functions of the power distribution system gradually evolves from the original independent policy control to the complex digital application scenario of multi-level division of labor, multi-equipment cooperation and multi-strategy collaboration, which has triggered profound changes in the production mode of the industry.Based on the top architecture of "cloud-side, channel layer, edge-side and perception layer" and intelligent equipment represented by intelligent terminal, the digitalized system of low-voltage distribution system reconstructs the data flow and signal flow of low-voltage platform area, which is an important research part to support the construction of new power system. This paper mainly introduces the basic situation of the digitalized system of low-voltage distribution system and its key equipment and core technology, analyzes the application scenario of digitalized business, and discusses the related comprehensive evaluation and test and detection technology.
