摘要(Abstract)：

以电力电子接口并网的新能源具有低惯性的特点,对扰动的响应能力差; VSG(虚拟同步发电机)能模拟传统同步发电机的特性,是消纳高比例新能源的有效解决方案。通过建立VSG数学模型,对含VSG的多机电力系统进行线性化处理,最后利用特征值分析法研究VSG对多机电力系统小干扰稳定性的影响,并与时域仿真法进行对比,所得结论可为VSG参数调节和布局等工程实际应用提供参考。
The renewable energy based on the power electronic interface is characterized by low inertia and poor response to disturbance. The VSG(virtual synchronous generator) can simulate the characteristics of the traditional synchronous generator and is an excellent solution for high-proportion new energy consumption. This paper firstly establishes a mathematical model of the VSG to linearize the multi-machine power system with VSG. Finally, the eigenvalue analysis method is adopted to study the influence of VSG on the small disturbance stability of multi-machine power system. Compared with the time-domain simulation method, it has important guiding significance for the practical engineering application of VSG parameter adjustment and layout.
