Patents by Inventor Nouredine HADJSAID

Nouredine HADJSAID has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11728652
    Abstract: A regulation process of an electrical distribution network that comprises a main power source, among one or more electrical sources, configured to impose on the network the voltage and frequency of a power circulating on the network to which one or more loads are connected. The process includes, in the event of a variation of one of the frequency or the voltage detected on the network, during a primary regulation, one adjustment step by the main source of the other between the frequency and the voltage, to maintain constant the ratio voltage/frequency.
    Type: Grant
    Filed: December 18, 2019
    Date of Patent: August 15, 2023
    Assignees: Schneider Electric Industries SAS, Institut Polytechnique de Grenoble
    Inventors: Lauric Garbuio, Kevin Marojahan Banjar Nahor, Vincent Debusscherer, Thi-Thu-Ha Pham, Nouredine Hadjsaid

  • Patent number: 10680437
    Abstract: The invention relates to a method of stabilization between a high frequency and a low frequency, of an electrical network supplying several sub-networks (22), each sub-network comprising a sub-network manager (24) and supplying N consumer sites (28), each site, j, comprising sheddable loads (34), the method comprising for each sub-network the following steps: ensuring a communication between each site and the sub-network manager thereof; periodically measuring the value of the sheddable power in consumed at each site; deducing for each site an estimated sheddable power; and dispatching to each site j (28) a threshold frequency, such that sheddable loads (34) of this site are unplugged when the frequency of the network drops below the threshold frequency, in which the sub-network manager (24) calculates the threshold frequencies in such a way that the variation of the sheddable powers as a function of frequency is substantially linear.
