Abstract
This paper presents a numerical method which makes use of the triangular factors of a singular gain matrix in order to determine the observable islands for a given set of measurements. The proposed method can accomplish this task in a noniterative manner by way of sparse triangular factorization and back substitution only. Numerical examples demonstrating the application of the proposed method to typical power systems are also included
