  • Patent number: 11855458
    Abstract: A method for controlling a renewable energy generator, the renewable energy generator being connected to a Point of Interconnection of an external power grid by a connecting network, wherein the connecting network has an associated impedance level. The method comprising: monitoring at least one parameter of the connecting network and the voltage level at the Point of Interconnection; generating, during normal operating conditions, at least one current injection profile based upon the at least one measured parameter and a predetermined injection profile; and operating the renewable energy generator, during a grid fault, to output current according to the at least one current injection profile, so as to achieve a current set point at the Point of Interconnection.

  • Patent number: 11799290
    Abstract: The present invention relates to a method for operating a power plant comprising a plurality of power producing units, the power plant being operatively connected to an associated power grid having a nominal grid frequency, the method comprising the steps of determining grid frequency variations of the associated power grid, and providing, in response to the determined grid frequency variations, an active power set-point to each of the plurality of power producing units, said active power set-point causing each of the plurality of power producing units to produce active power in response to said active power set-point, said produced active power comprising, in a frequency domain, one or more active power frequency components being different from one or more undesired frequency modes. The present invention also relates to a power plant controller for performing the method.
