含高渗透率分布式光伏的配电网电压越限解决方法研究综述
A Review of Solutions for Voltage Beyond Limits in Distribution Networks With High Penetration Distributed Photovoltaics
摘要
Abstract
In recent years,as China's energy transition has deepened and photovoltaics(PV)power generation technology has gradually matured while the cost of power generation has decreased,the proportion of distributed PV in the distribution network is increasing.Consequently,the power quality issues in the distribution network are becoming increasingly signific-ant,such as voltage beyond limits,voltage unbalance,line over-load,flicker and harmonic overload,etc.Among them,the main constraint on the capacity of distributed PV access is voltage exceeding limits.In this paper we firstly provide an overview of the commonly employed voltage regulation methods for for dis-tributed PV systems with high penetration levels,followed by a detailed exposition of each method.Finally,a comparison and analysis of the advantages and disadvantages of various voltage regulation methods areconducted,and relevant suggestions are made for future voltage regulation methods of distribution net-works with high-permeability distributed PV.关键词
