Abstract :
Voltage collapse and blackout can occur in an electric power system when load powers vary so that the system loses stability in a saddle node bifurcation. A direct method is presented to compute the load powers at which bifurcation occurs and which are locally closest to the current operating load powers. The computation is illustrated in the 6-dimensional load power parameter space of a 5 bus power system
