Abstract: Based on the current situation and main problems of the distributed photovoltaic grid connection in Shanxi,combined with the load and operation characteristics in power network,the problems in distributed photovoltaic shutdown caused by the increase of the voltage at the connecting points are analyzed,and the methods of adjusting and controlling the voltage of distributed photovoltaic power generation in low-voltage distribution network and the measures to administrate and improve this situation are researched.Then,the suggestions of motivating the positive development of distributed photovoltaic generation and improving the efficiency of using resources are proposed.
