Abstract

The present invention relates to a method for controlling a converter subgroup (3), wherein the converter subgroup (3) comprises a plurality of converter cells (7), each converter cell (7) being controlled by a first controller (21), at least two converter arrangements (5), each converter arrangement (5) being controlled by a second controller (23), wherein each converter arrangement (5) includes at least two of the plurality of converter cells (7), a third controller (25) controlling the at least two converter arrangements (5) by being in communication with each second controller (23), the method comprising the steps of determining a DC voltage of each one of the plurality of converter cells (7) to provide respective cell DC voltages, processing the respective cell DC voltages of each one of the at least two converter arrangements (5) to provide a DC measure, and using the processed DC measure at each one of the at least two second controllers (23) to control the at least two converter arrangements (5). The present invention further relates to a converter subgroup (3) for a Modular Multilevel Converter (MMC) (1) configured for carrying out a method according to the present invention and a MMC (1).
