As one example, a device includes at least one processor configured to determine, for a first controllable device in a system, based on a measurement of an output parameter and a minimum output parameter value, an output violation value for the first device. The processor is further configured to determine, based on a present input value for the first device, the output violation value, and an assistance requisition value corresponding to a second device, a target input value for the first device. The processor is further configured to cause the first controllable device to modify operation based on the target input value and a maximum input value for the first controllable device.Type: GrantFiled: October 14, 2021Date of Patent: May 14, 2024Assignee: Alliance for Sustainable Energy, LLCInventors: Guido Cavraro, Andrey Bernstein, Manish Kumar Singh

Patent number: 11581733Abstract: The present disclosure provides techniques for estimating network states using asynchronous measurements by leveraging network inertia. For example, a device configured in accordance with the techniques of the present disclosure may receive electrical parameter values corresponding to at least one first location within a power network and determine, based on the electrical parameter values and a previous estimated state of the power network, an estimated value of unknown electrical parameters that correspond to a second location within the power network. The device may further cause at least one device within the power network to modify operation based on the estimated value of the unknown electrical parameters. The leveraging of network inertia may obviate the need for probabilistic models or pseudo-measurements.Type: GrantFiled: November 12, 2020Date of Patent: February 14, 2023Assignees: Alliance for Sustainable Energy, LLC, The Regents of the University of Colorado, a body corporateInventors: Guido Cavraro, Andrey Bernstein, Emiliano Dall'Anese

Patent number: 10078318Abstract: A power flow control system for an interconnected power system, the interconnected power system comprising a plurality of electrical subsystems; an abstract framework configured to work as a utility maximizer under constraints (that applies to the electrical subsystems by specifying their capabilities, expected behavior and a simplified view of their internal state); and a plurality of agents. Each agent is responsible of one or a plurality of the electrical subsystems, comprises means configured to express an internal state of the electrical subsystem within a common system of coordinates, and has communication means configured to communicate among agents according to a protocol. The abstract framework means enables a composition of a set of the interconnected electrical subsystems into a further subsystem for which a further internal state is expressed within the same common system of coordinates used before, the further internal state being communicated with other agents according to the protocol.Type: GrantFiled: August 26, 2013Date of Patent: September 18, 2018Assignee: ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE (EPFL)Inventors: Jean-Yves Le Boudec, Andrey Bernstein, Mario Paolone
