Simulation and synchronization studies on voltage collapse model in power system

Dealing with power system became one of the most important arts in the field of power system, especially in the rapid increase of the distributed generation (DG) penetration to the distribution level which is a vital and important part of the entire power system. In this paper, a very special power system on voltage collapse model has been studied. We will establish its synchronization behavior. We investigate the chaos synchronization of two identical systems based on nonlinear observer. Control laws are derived analytically to achieve synchronization of the chaotic fractional order system which applying this voltage collapse model to a simple 3-bus power system model. Numerical simulations are provided to verify the theoretical analysis.
