标题： A Generalized Stability Analysis Method with Dynamic Phasors for LV AC Microgrids

摘要： 采用传统静态相量表示感应耦合线路是现有基于相量的简化稳定性分析方法在具有感应耦合线路的微电网中不适用的主要原因。 在文献中，动态相量已被提出用于感应线路的动态建模，以保持分析方法的简化结构。 在本研究中，提出了一种适用于由下垂控制逆变器组成的低压交流微电网的广义稳定性分析方法。 所提出的分析方法基于将动态相量引入现有的基于相量的稳定性分析方法中。 结果表明，带有动态相量的稳定性分析方法能够成功预测低压交流微电网的不稳定边界。 显示英文摘要

摘要： Representation of inductive coupling lines with conventional static phasors is the main reason of inadequacy of the existing phasors based simplified stability analysis methods for microgrids with inductive coupling lines. In the literature, dynamic phasors have been proposed for the dynamic modelling of inductive lines to conserve the simplified structure of the analysis method. In this study a generalized stability analysis method for LV AC microgrids, composed of droop controlled inverters, is presented. The proposed analysis method is based on the inclusion of dynamic phasors for inductive coupling lines into the existing phasors based stability analysis method. The results show that the stability analysis method with dynamic phasors successfully predicts the instability boundaries of LV AC microgrids.
