HIGHLIGHTS
- who: Yicheng Liao et al. from the (UNIVERSITY) have published the article: Complex-Valued Multifrequency Admittance Model of Three-Phase VSCs in Unbalanced Grids, in the Journal: (JOURNAL)
- how: - This Article proposes a multifrequency admittance model for voltage-source converters with three-phase unbalanced grid voltages.
SUMMARY
The unbalanced grid voltage, coupled through the ac-dc power conversion process, or asymmetric dq-frame control dynamics of the PLL and the dc-link voltage loop, leads to more harmonic components in the VSC current, e_g, the nonzero-sequence triplen harmonics. The complex . . .
