摘　　要：微电网并网位置选取的合理与否关系着配电网的安全、高效、经济运行。首先,从配电网的角度给出了微电网并网最优位置选取的详细流程;然后,在考虑工程实际的基础上确定微电网并网位置候选集,选取系统网络损耗率、系统电压偏差、配电网静态电压稳定性指标作为综合评判指标;再利用模糊层次分析法优化各指标权重,建立了微电网并网位置决策模型;最后以IEEE33节点作为算例进行仿真分析。仿真结果表明所提方法可实现微电网及配电网利益最大化。The proper interconnection location of microgrid determines the safe, efficient and economic operation of distribution network. Firstly, from the perspective of the benefits of distribution network, this paper illustrates the detailed process of selecting the optimal interconnection location of microgrid. Then, the candidate set from the consideration of practical engineering aspects is selected, and the evaluation system with the comprehensive index of real power loss rate, voltage deviation and static voltage stability is established. Thirdly fuzzy analytic hierarchy process （FAHP） is adopted to optimize relative weights of evaluation indicators and establish the decision-making model of selecting microgrid accessed location. Finally, in order to test the validity of stated theory, the intercon-nected impact is simulated under IEEE 33-bus system. Simulation results inicate that the proposed method can maximize the benefits of mi-crogrid and distribution network.
