Impedance-Based Stability Analysis in Power Systems with Multiple STATCOMs in Proximity
… voltage regulation and share burdens. Throughout stability assessment in this dissertation, it is shown, for the first time, that STATCOMs could interact with each other in a negative way in the small-signal sense due to their control, causing voltage instability, while loads and transmission …

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. …
