摘　　要：配电网接入分布式光伏电源,能明显提高光伏电源的比例大小,但输出过程中存在波动性、间歇性的特征,注入一定大小的分布式光伏功率,节点电压发生变化,并会改变单向潮流流向的特点,不利于配电网的稳定运行。本文以提高分布式光伏运用效果为研究目标,着重阐述了接入分布式光伏对配电网电压的影响以及工程计算内容,并提出降低影响的主要措施等,希望对相关工作有所帮助,进一步提高电压控制水平。The integration of distributed photovoltaic(PV)sources into distribution networks can significantly increase the proportion of PV power.However,the output of distributed PV is characterized by volatility and intermittency.The injection of a certain amount of distributed PV power can change node voltages and alter the unidirectional power flow characteristics,which is detrimental to the stable operation of distribution networks.This paper aims to improve the application effectiveness of distributed PV,focusing on the impact of distributed PV integration on distribution network voltage and the content of engineering calculations.It also proposes main measures to mitigate these impacts,hoping to provide assistance for related work and further enhance voltage control levels.
