D-Q Frame Impedance Based Small-signal Stability Analysis of PV Inverters in Distribution Grids
… converters present negative incremental impedance characteristics at their input while under regulated output control, which brings in the possibility of system instability. Recent evidence suggests that large-scale penetration of PV inverters increases the probability of instability. …

Impedance-Based Stability Analysis in Power Systems with Multiple STATCOMs in Proximity
… stability problem is induced by STATCOMs, d-q frame impedance-based stability analysis was used, for the first time, to explore the inherent power system instability problem with presence of STATCOMs as it provides an accurate understanding of the root cause of instability within the STATCOM …

Output Impedance Modeling and Measurement of a 28 kW Synchronous Generator
… a small-signal analysis is done on the d-q frame for the AC SM. Starting from formulating the SM's abc frame equations, a d-q transformation is done based on the SM rotor frame so that the inductance from the abc frame representation will be fixed. Then, the SM's fundamental parameters are …
