Abstract

This paper provides a tutorial introduction to the small-disturbance voltage-stability analysis as applied to the structure-preserving power system model. Salient features of this approach are (1) Both dynamic and static models that are relevant to voltage stability are included. In particular, the effect of load dynamics and generator current limits are considered. (2) Realistic load increases and a generation sharing scheme with relevant limits are included. (3) For a given load increase and generation sharing scenario, all possible critical points that may lead to voltage instability are systematically traced and identified.
