  "textContent": "A method for controlling a converter supplying a load is described. The converter is connected to an alternating current (AC) grid supplied by at least one renewable energy source. The method comprises receiving a measured AC grid voltage measured in the AC grid and a measured load voltage measured at an output of the converter. The method further comprises determining a magnitude of a fundamental positive-sequence component of the measured AC grid voltage. The method additionally comprises determining a load voltage reference from the magnitude and from a nominal load voltage reference, wherein the load voltage reference decreases when the magnitude decreases. The method also comprises determining a voltage error by subtracting the measured load voltage from the load voltage reference. The method further comprises controlling an output power of the converter based on the voltage error.",
