Summary of Bifurcation and Chaos Research in Electric Power System

The basic concepts of bifurcation and chaos and many different kinds of bifurcation phenomena in electric power system are introduced simply in this paper. The recent progresses of bifurcation and in this field of power system such as mechanism of power system nonlinear oscillation ,subsynchronous resonance and voltage collapse , the routes to chaos and the ways applied to refrain or delay bifurcation and chaos and short-term load forecasting methodology are summarized and discussed. The future research trends including revealing bifurcation and chaos phenomena in multi-machine power system,seeking bifurcation points rapidly,designing FACTS controllers to refrain bifurcation and chaos,controlling bifurcation and chaos,forecasting short-term load via chaos theory accurately and quickly are introduced.
