摘　　要：提出一种对规划阶段含微网的配电网电能质量进行合理评估的有效方法。该文首先论述了规划阶段电能质量评估的重要性与存在的困难,分析了不同分布式电源接入对电能质量的影响。然后以微网接入点短路容量与各分布式电源容量为数据基础,基于层次分析法对规划阶段接入不同结构微网的配电网进行电能质量评估。该方法可以根据微网中不同类型、不同排列方式的分布式电源对微网接入点造成的电能质量影响设定判断矩阵,使电能质量评估结果更加客观、科学、合理。A method of power quality assessment for distribution network incorporating micro-grid in planning stage is proposed. The importance and difficulties of power quality assessment in the planning stage are first discussed in the paper. And the paper analyses the impact on power quality of different DGs. Then considering the short-circuit capacity of the micro-network access point and the capacity of each DG, power quality of different micro-grids is assessed based on AHP in the planning stage. The method can set a judgment matrix according to different types and arrange- ment of DGs, thus making the assessment result more objective, scientific and reasonable.
