Stability analysis of power systems considering AVR and PSS output limiters

International Journal of Electrical Power & Energy Systems, 2009
Small-signal stability analysis in a power system uses a linearized approximation of its nonlinear model to analyze its behavior when subjected to small perturbations. In this approach, there is an implicit assumption that the perturbations are small enough so the imprecisions of the linear approximation with respect to the nonlinear model remain ...

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.
