METHOD AND CONTROL DEVICE FOR OPERATING A CONVERTER-BASED GRID UNIT

A method for operating a converter-based grid unit disposed electrically within an AC voltage section or adjacently to an AC voltage section of an electrical grid and electrically connected to the AC voltage section, includes using a control device to adjust infeed and drawing of active power and/or reactive power into and from the AC voltage section by actuating at least one converter of the converter-based grid unit. A multiplicity of measurement values is transmitted to the control device. The measurement values at least relate to different measurement variables and/or measurement locations within the AC voltage section or the converter-based grid unit. The control device selects a measurement value group from the multiplicity of available measurement values by selecting in accordance with a predefined selection guideline, and the at least one converter is actuated based on measurement values of the selected measurement value group.
