基于基频动态的电压源变换器阻抗建模参考坐标系选择

The fundamental frequency of ac power-electronic-based power systems may deviate from its nominal value, and it is highly affected by converter control dynamics. To capture the dynamics of fundamental frequency, two impedance modeling methods for voltage-source converters (VSCs) are reported, with respect to the selection of system reference frame. The first method is to model VSCs in a reference ...
