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.
