Voltage collapse phenomena are considered to be, very often, geographically local. On the other hand, they have been related to the nullification of the minimum singular value of the load-flow jacobian. In this paper, a new algorithm to divide the power system in coherent areas is proposed to perform voltage collapse analysis.
