Bifurcation and voltage collapse in the electrical power systems

Abstract EN

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.
