Method of determining an islanding solution for a power system comprising representing synchronising coefficients between generators and couplings between load buses and generators of the power system as a dynamic graph, calculating eigenvalues and eigenvectors of a graph laplacian describing the synchronising coefficients, identifying reference generators, calculating eigenvectors describing dynamic coupling between load buses and reference generators, using the synchronising coefficient and dynamic coupling eigenvectors to determine proximities between reference generators and other buses, assigning other buses to reference generators according to the proximities, selecting a threshold, identifying buses in weak-areas by using the threshold to identify buses having a proximity to their reference generator sufficiently similar to their proximity to another reference generator, determining the islanding solution by selecting connections to disconnect to split the power system into two or more islands based on an analysis of power flows only on connections to, or between, buses in weak-areas. |
