Abstract
Voltage stability is indeed a dynamic problem. Dynamic analysis is
important for a better understanding of voltage instability process. In this work
an analysis of voltage stability from bifurcation and voltage collapse point of
view based on a center manifold voltage collapse model. A static and dynamic
load models were used to explain voltage collapse. The basic equations of a
simple power system and load used to demonstrate voltage collapse dynamics
and bifurcation theory. These equations are also developed in a manner, which is
suitable for the Matlab-Simulink application. As a result detection of voltage
collapse before it reach the critical collapse point was obtained as original point.
