含高比例分布式光伏接入的配电网韧性评估方法
Resilience evaluation method of distribution networks with high proportion distributed photovoltaic integration
摘要
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 engen-dered 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 conduc-ted 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.关键词
