微电网小干扰稳定性分析多采用基于系统线性化模型的特征值分析法,在系统模型及参数已知情况下可获得准确结果。然而,具有低惯性、弱阻尼特征的微电网在实际运行过程中系统拓扑及参数会动态变化。为此,文中提出一种主动小干扰微电网稳定性评估方法,该方法无须获取系统结构及准确参数,通过向系统注入电流脉冲,采集并提取电压动态响应曲线,采用希尔伯特-黄变换方法辨识响应曲线中振荡模态的参数,获得系统振荡模态的阻尼比以评估微电网小干扰稳定性。同时,为对比验证所提方法的正确性,在微电网结构和参数均已知情况下建立微电网的小信号模型,以求解的主导特征根与所提方法的辨识结果进行比较。最后,分别基于MATLAB/Simulink及StarSim硬件在环软件建立系统仿真和实验平台,仿真和实验结果验证了所提方法的正确性和有效性。
The characteristic value analysis method based on the system linear model is widely adopted in small-signal stability analysis for microgrid
which can obtain accurate results when the system model and parameters are known. However
the system topology and parameters of the microgrid with low inertia and weak damping characteristics change dynamically during the real operation process. To solve the problem
this paper proposes an active small-signal stability assessment method for microgrid
which does not need to obtain the system structure and accurate parameters. By injecting the current pulse into the system
and collecting and extracting the voltage dynamic response curve
the Hilbert-Huang transform (HHT) is used to identify the parameter of the oscillation mode in the response curve
so that the damping ratio of the system oscillation mode can be obtained to evaluate the small-signal stability of the microgrid. At the same time
to verify the correctness of the proposed method
a small-signal model of the microgrid is established with the known structure and parameters of the microgrid
and the leading characteristic roots of the solution are compared with the identification results of the proposed method. Finally
system simulation and experimental platforms are established based on the MATLAB/Simulink and Starsim HIL
respectively. The simulation and experimental results verify the correctness and effectiveness of the proposed method.
