A Modified Sequence-Domain Impedance Definition and Its Equivalence to the dq-Domain Impedance Definition for the Stability Analysis of AC Power Electronic Systems
Rygg, Atle; Molinas Cabrera, Maria Marta; Cai, Xu; Chen, Zhang (Peer reviewed; Journal article, 2016)Representation of ac power systems by frequency-dependent impedance equivalents is an emerging technique in the dynamic analysis of power systems including power electronic converters. The technique has been applied for ... -
Frequency-dependent source and load impedances in power systems based on power electronic converters
Rygg, Atle; Molinas Cabrera, Maria Marta; Cai, Xu; Chen, Zhang (Conference object; Peer reviewed, 2016)Representations of power systems by frequency dependent impedance equivalents is an emerging technique in dynamic analyses of power systems including power electronic converters. The technique has been applied for decades ... -
On the Equivalence and Impact on Stability of Impedance Modeling of Power Electronic Converters in Different Domains
Rygg, Atle; Molinas Cabrera, Maria Marta; Chen, Zhang; Cai, Xu (Journal article, 2017)Small-signal analysis of power electronic converters and systems is often carried out by impedance-based methods. At the core of these methods lies the impedance modeling, which can either be obtained through analytical ... -
Parametric Stability Assessment of Single-Phase Grid-Tied VSCs Using Peak and Average DC Voltage Control
Chen, Zhang; Isobe, Takanori; Suul, Jon Are Wold; Dragicevic, Tomislav; Molinas Cabrera, Maria Marta (Journal article; Peer reviewed, 2021)A type of peak-value dc voltage control (denoted as PK control) was proposed in the literature for supporting the use of a smaller dc-side capacitance when the single-phase voltage source converter is operated as a static ...
