Dynamic response of loads has a significant effect on system stability and directly determines the stability margin of the operating point. Inherent uncertainty and natural variability of load models make the stability assessment especially difficult and may compromise the security of the system. We propose a novel mathematical “robust stability” criterion for the assessment of small-signal stability of operating points. Whenever the criterion is satisfied for a given operating point, it… 
Network-based analysis of long-term voltage stability considering loads with recovery dynamics
Stability conditions are proposed for static and small-disturbance voltage stability of power systems, which reveal the interactions between network graph, load demand and load characteristics and sheds new light on the static andsmall-disturbed voltage stability mechanisms.

Contraction Analysis of Nonlinear DAE Systems
It is shown that an important property of a contracting DAE system is that the reduced system always contracts faster than any synthetic counterpart, and there always exists a synthetic system, whose contraction rate is arbitrarily close to that of the DAE.
