电压源变换器的状态反馈重塑控制

Admittance reshaping is a widely used strategy to address the converters low-frequency stability issues in weak grid, caused by the PLL and its interaction with the dc and ac voltage controls. However, the asymmetric control of the $d$- and $q$-axis current references and the coupling between the converter ac and dc sides restricts the damping capability of single-input single-output feedbacks. Th...
