Since low-voltage distributed photovoltaic(PV)access has a great impact on the distribution network,it is of great significance to discuss the impact of reducing low-voltage distributed PV access on the distribution network.On the basis of introduc-ing the distributed PV grid-connection system model,the impact of low-voltage distributed PV access on the voltage and loss of the dis-tribution network is analyzed,and the management and technical measures to reduce the impact of grid connection are put forward,which provides reference for the grid connection of distributed PV power generation in low-voltage distribution network,and is condu-cive to the safe and stable operation of the new distribution network.
