Abstract :
This paper introduces a new fully developed online EMS function: the topology estimator. This new function produces an estimated MW-only power flow model of the network, in which erroneous switch statuses have been detected, identified and corrected. This is important because MW-only models are currently used for many market and security applications. Equally importantly, the corrected switch statuses can be inputted as data overrides to any conventional state estimator.
