Abstract: A method for controlling a modular multi-level converter(12) comprises the steps of: collecting control input variables (26) from the converter(12); transmitting the control input variables (26) to a controller (14) of the converter (12) via a first communication medium (32); determining, in the controller (14), an actual state of the converter(12) and at least one control output variable (28) based on a model (30) of the converter(12); and transmitting the control output variable (28) to the converter(12) for controlling the converter via a second communication medium (28). The model (30) of the converter(12) accounts for the first and/or the second communication medium (32, 34).
