The distributed photovoltaic(PV)power system is considered to be one of the most important forms of energy in the future with the vigorous development of green power and the construction of new power systems.As the penetration rate of photovoltaic continues to increase,the traditional distribution network trend structure will be changed,resulting in the impact of power quality,security protec-tion and planning of the distribution network.The development status of distributed PV power generation system was outlined,the charac-teristics of distributed PV grid-connected and the working principle was analyzed.Secondly,the impacts of distributed PV grid-connected access to the distribution network and governance measures were outlined,analyzed and summarized.Finally,it was expected to provide reference for the rapid development of distributed PV power access to high penetration of renewable energy distribution system.
