Abstract
This paper focuses on computing and interpreting the significance of the observability Jacobian singularities. Previous efforts have focused on developing an observability index and determining the effects of model/measurement changes to the observability formulation. Using this index, the singularities of the Jacobian are extracted, and preliminary results indicate that there is a duality between the loss of stability (whether it be phase or voltage stability), and the loss of observability. Thus, providing a single dual-use metric capable of forecasting both stability and observability characteristics of a system. The results are illustrated using a sample 3-bus system.
