随着绿色电力的大力发展和新型电力系统的建设，分布式光伏发电系统已经成为未来的重要能源形式之一。由于光伏渗透率的不断提高，分布式光伏电源并网会改变传统的配网潮流结构，对配电网的电能质量、安全保护以及规划等方面产生影响。首先概述了分布式光伏发电系统的发展现状，分析分布式光伏并网的特点以及工作原理。其次，对分布式光伏并网接入配网造成的影响及治理措施进行概述分析和总结。最后期望为分布式光伏电源接入高渗透率的可再生能源配电系统的快速发展提供参考。

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 protection and planning of the distribution network. The development status of distributed PV power generation system was outlined, the characteristics 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.
