  • Hierarchical implicit controller for shielded system in a grid
    Patent number: 10983484
    Abstract: A system or a method to at least partially steer systems, e.g. heating and/or cooling and clusters of systems, when the controller of the system is unknown or when the transfer function of the system is unknown. The steering of the energy flow, e.g. heating/cooling/electrical energy, includes providing energy to the system or the cluster of systems and preferably to manage common constraints, like capacity problems.
    Type: Grant
    Filed: December 27, 2017
    Date of Patent: April 20, 2021
    Assignees: NODA INTELLIGENT SYSTEMS AB, VITO NV
    Inventors: Dirk Vanhoudt, Gowri Suryanarayana, Fjo De Ridder, Johan Christian Johansson

  • Controller for energy supply systems
    Patent number: 9618215
    Abstract: The present invention relates to energy supply systems which comprise an energy storage unit and an energy production unit. Control methods according to the invention advantageously allow to calculate an operational cost of the energy supply system based on the energy flux that can be supplied by the system and the energy flux that is demanded externally from the system. The operational cost can be calculated for all possible values of the above parameters in advance. The calculated parameters can be stored in an array in a device implementing methods of the invention. Methods of the invention allow to operate an energy supply system so as to guarantee that at any instant a predetermined (nonzero) amount of energy flux can be supplied by the energy storage unit.
