摘　　要：分布式电源(DG)接入的节点位置及接入容量会对电压偏差、节点静态电压稳定和网络损耗产生相应的影响。为了量化评估这些影响,首先定义了系统电压偏差性指标、系统静态电压稳定性指标和系统网络损耗指标,进而提出了以系统电压偏差变化、系统静态电压稳定性提升和系统网络损耗变化为基础的DG接入配电网的综合影响指标,并借助IEEE 33节点系统分析了指标的价值与意义。The position and capacity of distributed generation(DG)access to distribution network will affect voltage deviation,static voltage stability and network loss.In order to achieve quantitative assessment of these effects,firstly,voltage deviation index,static voltage stability index and network loss index are defined.And then a comprehensive impact index of DG access distribution network is proposed,which is based on the voltage deviation reduction,system static voltage stability improvement value and system loss reduction,and the value and significance of this index is analyzed based on the IEEE 33 node system.
