Abstract
Nonlinear bifurcation theory is very powerful and efficient to deal with multifarious nonlinear phenomena emerging from physics, biology, engineering, and economics. However, the execution of augmented system for bifurcation points will be very complicated for a system with too many variables. The purpose of this paper is to give a new optimization based method for computation of fold and Hopf bifurcation points and discuss their applications in stability analysis of power system. The validity of the proposed method has been testified by a WSCC9-bus power system in which the load increment at any bus was taken as a parameter.
