Abstract：The voltage stability of an isolated power systems (IPS) with power electronic devices highly integrated is a key factor that needs to be considered for the design and operation of the system. In order to reduce the amount of calculation and improve the analysis effect of system stability, this paper has proposed an analytic method for the voltage stability of the IPS based on catastrophe theory. The potential function, equilibrium surface and bifurcation set of a typical IPS are obtained through the mathematical deduction results. A dovetail manifold equation is then established for stability analysis, and the voltage stability margin index of IPS is given according to the catastrophe theory. The example of a certain IPS has verified the proposed method.
