Impact of the Grid Connection of Distributed Photovoltaic Power Generation on the Distribution Network
Currently,the distribution network in China is mainly of the medium-and low-voltage type and can not access a large number of the photovoltaic power generation system simultaneously,or it will exceed the capacity limit of the medium-and low-voltage distribution network,leading to changes in the actual current operation mode of the distribution network.If the number of access to the photovoltaic power generation system significantly exceeds the safe operation limit of the distribution network,it will have an impact on the normal operation of the distribution network and even cause serious safety accidents.Based on this,the article mainly starts with the impact of the grid connection of distributed photovoltaic power generation on the safety of the distribution network,and analyzes some solutions currently used in China,for reference.
