摘要

微电网中变流器的电磁暂态过程加剧了微电网的动态特性分析难度，为了快速准确地分析微电网的动态特性，文中采用动态相量法建立了逆变型分布式电源微电网的动态相量模型。通过MATLAB/Simulink分别用动态相量模型和电磁暂态模型对含2个逆变型分布式电源的微电网进行仿真分析，仿真结果表明，动态相量模型在较高精度范围内近似电磁暂态模型，验证了模型的正确性和有效性。而且，所提出的动态相量模型在保证较高精度的同时，提高了仿真速度，节省了仿真时间，为复杂微电网的建模提供了一种新方法。

Abstract

In order to quickly and accurately overcome the difficulty in microgrid dynamic characteristics analysis aggravated by the electromagnetic transient process of the converter，a dynamic phasor model of the microgrid with inverter-interfaced distributed sources is presented.The dynamic phasors model and electromagnetic transient（EMT）model for the microgrid including two inverter-interfaced distributed sources are simulated by the MATLAB/Simulink.Compared with the electromagnetic transient model，the simulation results show that in the range of high accuracy，the simulation results of two models are approximate to each other.The simulation results have further verified the correctness and validity of the model.Meanwhile the proposed model not only yields higher accuracy，but also reduces the calculation complexity and saves simulation time，providing a new method for complex microgrid modeling.
