摘要

高比例分布式光伏接入配电网后会引发一系列电能质量问题

使配电网的韧性下降，导致敏感负荷无法正常运行，甚至中断造成巨大的经济损失。为了量化高比例分布式光伏接入后引发的电能质量问题对配电网韧性的影响，提出利用电能质量指标越限裕度构建梯形曲线的方法，结合MATLAB和Open-DSS的仿真验证了分布式光伏在不同接入情况下对韧性的影响，并从规划阶段提出了提高配电网韧性的建议。

Abstract

The integration of distributed photovoltaic(PV)systems into distribution networks at a high proportion can precipitate a multitude of power quality issues

thereby diminishing the resilience of these networks.This compromised resilience can weaken sensitive loads

potentially leading to operational failures

interruptions and substantial economic losses.To quantitatively assess the impact of these power quality issues on the resilience of distribution networks engendered by the extensive integration of distributed PV

this study introduces a novel method that employs the margin of power quality indices exceedance to construct trapezoidal curves.Finally

through a combination of simulations conducted in MATLAB and OpenDSS

this paper validates the impact of distributed PV on network resilience under different cases.Furthermore

suggestions for power companies to enhance the resilience of the distribution network are also presented during the planning phase.
