The influence of dynamic element characteristics to voltage stability based on bifurcation theory

Multiple voltage stability incidents show that system dynamic components have a great impact on voltage stability. This article mainly analyzes and summarizes the impaction on voltage stability based on the bifurcation theory caused by dynamic characteristics of main components in the power system such as load characteristics, generator characteristics, OLTC and Static Var Compensator (SVC).It Proposes that we should make full use of bifurcation theory to enhance the influent study of these dynamic elements on voltage stability and there is a key research direction for future that we select multiple parameters from dynamic components to do multi-parameter research on voltage stability using bifurcation theory.
