Abstract: A system for dynamic rating of a power grid may include a plurality of terminal units, and a controller. The terminal units may detect a voltage phasor and a current phasor at nodes of the power grid. The controller may, based on the voltage phasors and the current phasors of the plurality of nodes, determine a dynamic thermal stability power rating for each line, a dynamic angular stability power rating for each node, and a dynamic voltage stability power rating for each node. The controller may, based on the dynamic thermal stability power rating, the dynamic angular stability power rating, and the dynamic voltage stability power rating, determine a dynamic system rating for the power grid. The controller may control the power grid in response to the dynamic system rating.

Abstract: A system includes a power transformer diagnosis and prognosis device having memory circuitry storing a plurality of models. Each of the plurality of models comprises correlations between potential combinations of operational and non-operational power transformer data and potential conditions of one or more subsystems of a power transformer and include a physics-based model and an empirical model. The system includes communication circuitry configured to receive a particular combination of operational and non-operational power transformer data related the power transformer.
