Abstract :
The law of how the minimum absolute eigenvalue of the Jacobian matrix varies with the load of power systems is analyzed, based on which a new approach is proposed to estimate the static voltage collapse. BPA is used to calculate power flows with the increasing loads. Using the new approached method, the critical point of the static voltage collapse can be conveniently estimated under various power system operation states. The approach is tested on the standard IEEE9 system
