| 中文摘要: |
| 为了解决大规模电动汽车充电桩并入电网时对电力系统产生的不良影响，虚拟同步发电机技术被应用于电动汽车的充电领域，利用可调的惯性和阻尼，增强车网互联系统的稳定性。将基于序阻抗建模的方法分析虚拟同步发电机在充电领域的稳定性作为研究重点，对虚拟同步发电机进行了建模和控制分析，并得到了其频率耦合特性及耦合效应，通过推导出的阻抗模型分析控制参数和稳定性之间的关系。最后，Matlab/Simulink的仿真波形也验证了分析结果。 |
| 英文摘要: |
| In order to solve the adverse effects on the power system when large-scale electric vehicle charging piles are integrated into the power grid, the virtual synchronous generator technology （VSG）is applied to the charging field of electric vehicles. The adjustable inertia and damping are used to enhance the performance of the vehicle-network interconnection system stability. The analysis of the stability of VSG in the charging field based on the method of sequence impedance modeling is the focus. The modeling and control analysis of the virtual synchronous genertater are carried out, and its frequency coupling benefits and coupling characteristics are obtained. The relationship between the control parameters and the stability is analyzed through the derived impedance model. Finally, the simulation waveforms of Matlab/Simulink also verify the analysis results. |
