To address the power quality issues in a multiple grid-connected-converter system (MGCCS) for renewable energy, the series and parallel models of MGCCS are established at first based on the harmonic state space (HSS) method. The HSS models account for high-frequency components during the switching process, with its internal Toeplitz matrix effectively capturing the harmonic coupling within the converters. Based on the series and parallel HSS models of MGCCS, a virtual resistor is introduced to improve the model, and the impact of grid impedance is considered to simulate the multi-converter grid-connected system. In addition, the harmonic stability of this system is investigated by analyzing the eigenvalues of the state matrix. The influences of main circuit and controller parameters on the harmonic instability are analyzed in depth, and the oscillation frequencies in harmonic instability modes are predicted. Simulation results based on MATLAB/Simulink and RT-LAB experimental results validate the accuracy of the improved HSS models and the harmonic stability analysis.

为解决新能源多变流器并网系统MGCCS(multiple grid-connected-converter system)中的电能质量相关问题,首先基于谐波状态空间HSS(harmonic state space)方法建立MGCCS的串联和并联模型。HSS模型考虑了开关过程中的高频分量,其内部的Toeplitz矩阵能够有效捕捉变流器内部的谐波耦合。在建立MGCCS串联和并联HSS模型的基础上,引入虚拟电阻改进模型,并考虑电网阻抗的影响,以模拟多变流器并网系统。通过对状态矩阵的特征值分析,对多变流器互联系统的谐波稳定性进行研究。研究深入分析了主电路和控制器参数对谐波不稳定性的影响,预测谐波不稳定模式的振荡频率。MATLAB/Simulink仿真结果及RT-LAB实验结果验证了基于HSS改进模型的正确性以及谐波稳定性分析的准确性。

为解决新能源多变流器并网系统MGCCS(multiple grid-connected-converter system)中的电能质量相关问题,首先基于谐波状态空间HSS(harmonic state space)方法建立MGCCS的串联和并联模型。HSS模型考虑了开关过程中的高频分量,其内部的Toeplitz矩阵能够有效捕捉变流器内部的谐波耦合。在建立MGCCS串联和并联HSS模型的基础上,引入虚拟电阻改进模型,并考虑电网阻抗的影响,以模拟多变流器并网系统。通过对状态矩阵的特征值分析,对多变流器互联系统的谐波稳定性进行研究。研究深入分析了主电路和控制器参数对谐波不稳定性的影响,预测谐波不稳定模式的振荡频率。MATLAB/Simulink仿真结果及RT-LAB实验结果验证了基于HSS改进模型的正确性以及谐波稳定性分析的准确性。

To address the power quality issues in a multiple grid-connected-converter system (MGCCS) for renewable energy, the series and parallel models of MGCCS are established at first based on the harmonic state space (HSS) method. The HSS models account for high-frequency components during the switching process, with its internal Toeplitz matrix effectively capturing the harmonic coupling within the converters. Based on the series and parallel HSS models of MGCCS, a virtual resistor is introduced to improve the model, and the impact of grid impedance is considered to simulate the multi-converter grid-connected system. In addition, the harmonic stability of this system is investigated by analyzing the eigenvalues of the state matrix. The influences of main circuit and controller parameters on the harmonic instability are analyzed in depth, and the oscillation frequencies in harmonic instability modes are predicted. Simulation results based on MATLAB/Simulink and RT-LAB experimental results validate the accuracy of the improved HSS models and the harmonic stability analysis.
