In today's critical period of energy transition,the distributed photovoltaic power generation system is getting more and more attention because of its clean and renewable characteristics.At the same time,it also brings some challenges to the stable operation of the power grid,especially in terms of power quality and power grid security,how to effectively manage and control the impact of distributed photovoltaic system grid connection,has become a key problem to be solved urgently.Based on this,the paper deeply analyzes the basic working principle of distributed photovoltaic power generation system,focuses on the four application points of power grid access technology,including the design of access voltage level,power quality monitoring,anti-reflux control and islanding effect detection,so as to promote the efficient integration of distributed photovoltaic power generation system and the traditional power grid.
