The invention relates to a method in connection with control of a grid connected converter and a converter. The control comprises the steps: forming a current reference for the converter, feeding thecurrent reference to a current controller for producing a voltage reference for the converter. The method comprises high-pass filtering the produced voltage reference or measured output voltage of theconverter and modifying the current reference with the high-pass filtered voltage reference or measured output voltage of the converter. 本公开涉及与并网转换器的控制有关的方法以及转换器。该控制包括形成转换器的电流基准，将电流基准馈送到电流控制器以产生转换器的电压基准。该方法包括对所产生的电压基准或转换器的测量输出电压进行高通滤波，并且利用经高通滤波的电压基准或转换器的测量输出电压来修改电流基准。
