Publication number: 20230074995Abstract: A method for controlling a power distribution system having a number of nodes and controllable grid assets associated with at least some of the node includes acquiring observations via measurement signals associated with respective nodes and generating a graph representation of a system state based on the observations and topological information of the power distribution system. The topological information is used to determine edges defining connections between nodes. The observations are used to determine nodal features of respective nodes, which are indicative of a measured electrical quantity and a status of controllable grid assets associated with the respective node. The graph representation is processed using a reinforcement learned control policy to output a control action for effecting a change of status of one or more of the controllable grid assets, to regulate voltage and reactive power flow in the power distribution system based on a volt-var optimization objective.Type: ApplicationFiled: July 8, 2022Publication date: March 9, 2023Inventors: Xian Yeow Lee, Yubo Wang, Ulrich Muenz

Publication number: 20150176686Abstract: An anti-rotation device prevents relative rotation between first and second members, one member being telescopingly disposed about the other and at least one member being linearly displaceable along a central axis. First and second guide surfaces are provided on the first member and extend generally parallel with each other and the central axis. First and second rollers are connected with the second member and are each rotatable about an adjustably fixed axis on the second member. The first roller is rollable along the first guide surface to prevent angular displacement between the two members when the displaceable member moves in a first direction and the second roller is rollable along the second guide surface to prevent angular displacement between the two members when the displaceable member moves in an opposing direction. The contact between the rollers and guide surfaces provide a radial degree of freedom to the anti-rotation device.Type: ApplicationFiled: December 20, 2013Publication date: June 25, 2015Applicant: AKTIEBOLAGET SKFInventors: Sebastien Lecluse, Jerome Dubus, Marcus Hong Yeow Lee, Frans Grove, Parveen Chandila, Christian Boch
