Modular SSTs which can be interpreted as modular multilevel converters with an isolated DC-DC output stage per module, are designed with redundant modules to increase reliability. Usually, each of the three arms operates independently, and therefore, only a fixed number of faulty modules can be compensated in each arm, even if all modules are operational in the remaining two arms. With the proposed zero-sequence voltage injection, up to 100% more faulty modules can be compensated in an arm by employing the same hardware. In addition, module power imbalances are nearly eliminated by utilizing a fundamental frequency zero-sequence voltage. A dominant 3rd harmonic zero-sequence voltage injection in combination with the 5th, 7th and several higher order harmonics with adaptive (small) amplitudes minimize the required arm voltages at steady-state. For nominal operation or symmetrical faults, the proposed technique is equivalent to the well known Min-Max voltage injection, which already reduces the peak arm voltage by 13.4% compared to a constant star point potential. A statistical analysis proves, that the expected number of tolerable faulty modules of the 1MW SST increases by 12% without the need for additional hardware."}],"type":"conference","publication":"23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)","language":[{"iso":"eng"}],"keyword":["Solid-State Transformer","Zero sequence voltage","Fault handling strategy","Power balance control technique","Three-phase system"],"user_id":"34289","department":[{"_id":"52"}],"_id":"29938"},{"doi":"10.1109/speedam48782.2020.9161971","conference":{"start_date":"2020-06","name":"SPEEDAM","location":"Sorrent, Italy"},"title":"Emulation of Microgrids for Research and Validation of Control and Operation Strategies","date_created":"2022-02-23T09:06:35Z","author":[{"orcid":"0000-0002-4212-6555","last_name":"Stille","full_name":"Stille, Karl Stephan Christian","id":"30152","first_name":"Karl Stephan Christian"},{"first_name":"Daniel","orcid":"0000-0003-3367-5998","last_name":"Weber","full_name":"Weber, Daniel","id":"24041"},{"last_name":"Lange","id":"78801","full_name":"Lange, Jarren","first_name":"Jarren"},{"last_name":"Vogt","full_name":"Vogt, Thorsten","first_name":"Thorsten"},{"last_name":"Wallscheid","orcid":"https://orcid.org/0000-0001-9362-8777","full_name":"Wallscheid, Oliver","id":"11291","first_name":"Oliver"},{"full_name":"Böcker, Joachim","id":"66","last_name":"Böcker","orcid":"0000-0002-8480-7295","first_name":"Joachim"}],"publisher":"IEEE","date_updated":"2022-02-23T12:49:52Z","citation":{"ama":"Stille KSC, Weber D, Lange J, Vogt T, Wallscheid O, Böcker J.
