  • Condition-based management of power transformers
    Patent number: 9312695
    Abstract: Methods and arrangements for managing implementation of a power transformer. There is determined at least one parameter currently relating to operation of a transformer, as well as a revenue value currently assigned to the transformer. There is determined a depreciation value currently assigned to the transformer. There is determined a power output for the transformer for a future time slot that increases total revenue with respect to a life cycle of the transformer, the power output being determined based on the at least one parameter, the revenue value, and the depreciation value.

  • Historic storage of dual layer power grid connectivity model
    Patent number: 8738351
    Abstract: A power grid model system, method and computer program product which includes a switching state processor, a topological processor, an equipment update processor, and a historic power grid model for a power grid. The historic power grid model has an equipment layer and a topology layer. Responsive to a switch operated in a power grid, the switching state processor is notified of the operated switch, notifies the topological processor of the operated switch and notifies the power grid model for updating of the historic power grid model; and the topological processor determines the extent of the update of the power grid model, parses through details of the equipment layer and updates the topology layer in the power grid model.
