Overview of Distributed Photovoltaic Grid Connection Mode and Data Acquisition and Control Mode

Under the target background of "double carbon" and county wide distributed photovoltaic and other related policies, the extensive construction of distributed new energy puts forward higher requirements for the scientificity of distributed new energy planning. The active distribution network scheduling faces the operation and management problems after the participation of large-scale distributed new energy, which increases the risk and difficulty of power grid operation and management, and it is imperative to improve the regulation and control ability of active distribution network. This paper selects and summarizes the current grid connection methods of distributed photovoltaic and various methods of data acquisition, summarizes and compares the adaptation scenarios of various methods, and helps the orderly grid connection of distributed photovoltaic in a high proportion.
