摘　　要：对分布式发电(Distributed Generation,DG)接入配电系统后所产生的影响进行了研究和评估。通过分析DG接入对电网产生的各种影响,总结提出了反应电网损耗、电压质量、可靠性、环境影响程度等的量化指标,分析研究了针对各指标的计算方法。并基于层次分析法和主成分分析法相结合的方法实现各指标的线性加权,从而综合评估DG对电网的影响。以20节点系统为例,在接入不同DG情况下对所述计算方法和综合评估方法进行了仿真验证,并对结果进行了分析和讨论。This paper studies and evaluates influences of Distributed Generation（DG）on the distribution networks.B y analyzing various impacts after DG accessing to the network,t his paper summarizes and proposes several quantification indices to show network losses,v oltage quality,r eliability,environmental impact degree,e tc,a nd presents the calculation methods corresponding to different indices.To fulfill integrated evaluation of DG impact on distribution network,a linear weighting of each index is adopted.And the weight factor is defined based on the combination of the Analytic Hierarchy Process（AHP）and the Principal Component Analysis（P CA）.On the basis of the 20-node system,the simulation of the computation method and the integrated evaluation method is carried out aiming to different situations of DG,and simulation results are analyzed and discussed.
