Publication number: 20210104964Abstract: Method for controlling a generator comprising an inverter and an electrical energy source, the generator being configured to deliver output electrical values to an electrical distribution grid, the inverter being controlled by a control law, the control law comprising a set of fixed values of parameters for modelling the functioning of a synchronous virtual generator so that the control law is configured to determine at least one target output value that must be delivered by the generator to the electrical distribution grid.Type: ApplicationFiled: September 25, 2020Publication date: April 8, 2021Applicants: Schneider Electric Industries SAS, Institute Polytechnique de GrenobleInventors: Audrey MOULICHON, Mazen ALAMIR, Lauric GARBUIO, Mustapha Amine RAHMANI, David GUALINO, Vincent DEBUSSCHERE, Nouredine HADJ-SAID, Miao-Xin WANG

Patent number: 10840708Abstract: A method controls a microgrid having at least one renewable plant of distributed renewable energy resources and at least one generator plant of distributed non-renewable energy resources, and each plant has a local controller. The method includes providing type and power size of each plant to each local controller. At each local controller, measuring the frequency and estimating the total power load demanded based on the measured frequency. At the local renewable controller, decreasing the frequency at which power is supplied when the supplied power falls below the estimated power load and increasing the frequency when the supplied power exceeds the estimated power load. And at the local generator controller, increasing power supply in response to detecting a decrease in frequency, and decreasing power supply in response to detecting an increase in frequency.Type: GrantFiled: November 16, 2018Date of Patent: November 17, 2020Assignee: Schneider Electric Industries SASInventors: Jean Dobrowolski, David Gualino, Mazen Alamir, Seddik Bacha

Patent number: 9004930Abstract: A set of outlets including a sheet and a base adapted for electrical work to each other in a detachable manner, the sheet including at least two electric tracks in a concentric ring configured to respectively cooperate with electrical contacts of an electrical socket. A magnetic mechanism generates a first control force for positioning and holding the sheet on the base. The base includes at least two movable electric contacts movable between a first position inside the base and a second position outside the base to be respectively in direct electrical contact with the electrical tracks, the first force control to move the electrical contacts between the first and the second positions.Type: GrantFiled: August 11, 2011Date of Patent: April 14, 2015Assignee: Schneider Electric Industries SASInventors: David Gualino, Rachid Makhlouche, Charles Blondel

Patent number: 6654482Abstract: The method for locating a mobile unit relatively to an intermittent lighted beacon consists in calculating, on the basis of data concerning the mobile movement, the position of the discrete scatterer on the linear barrette obtained by a point by point subtraction of two linear images of the same image field, one wherein the beacon is alight and one wherein it is not alight, and the derivative of the position. On the basis of said data, the distance separating the beacon thus represented and a mark related to the mobile unit is calculated, and the beacon angular position relative to said mark linked with the mobile.Type: GrantFiled: May 3, 2000Date of Patent: November 25, 2003Inventors: Michel Parent, David Gualino
