The growing use of power electronics converters in the power system leads to emerging
stability issues. However, existing impedance models are insufficient for analysis of the …

The dominance of power electronics in modern power systems makes it difficult to study
stability with sufficient accuracy given the available information, so it is necessary to …

Impedance-based stability analysis is widely adopted for small-signal stability demonstration
of power electronics dominated power systems. Stability assessment can be performed …

Frequency-Domain (FD) modal method is a useful tool for oscillation analysis of converters-
dominated systems. In this regard, the nodal admittance and loop-gain models are often …

Impedance measurement techniques based on small-signal injections in ac power system
have been well developed but a gap in the analysis is that the selection of an injection …

The impedance-based criteria are well known to assess the stability of DC systems by
impedance measurement method. However, these criteria apply to the DC systems with the …

Most of the new renewable generation in power systems is connected through Grid-
Following inverters (GFL). The accompanying decline of fossil-fuelled synchronous …

State space is widely used for modeling power systems and analyzing their dynamics but it
is limited to representing causal and proper systems in which the number of zeros does not …

Participation analysis based on whole-system impedance models enables the root-cause
stability analysis of large-scale power systems when state-space models are unavailable. To …

Photovoltaic (PV) power systems are becoming one of the most popular green power
systems. Power converters are used in these systems. Among them, quasi-Z-source …
