Abstract

An analytical framework is presented for the analysis of voltage collapse as a dynamic phenomenon. The approach depends on linking static and dynamic aspects within differential-algebraic models which preserve network structure and facilitate the use of a novel approach to modeling aggregate (dynamic) load. Directions for stability/bifurcation analysis are indicated. In particular, new Lyapunov functions for large-disturbance voltage stability analysis can be derived. It has been shown that there are many similarities between generator (angle) and load system stability analysis revolving around the dynamic behavior of differential-algebraic models
