In view of the problems of difficult parameters setting and slowly dynamic response of double closed-loops PI control adopted by conventional MMC-HVDC system
we propose a model predictive control method applied in MMC-HVDC. Traditional module capacitor voltage-sharing sequencing is limited in large-scale level MPC control strategy. Therefore
SSPFM capacitance voltage-sharing group sequencing is put forward. SSPFM-MPC control strategy endows MMC-HVDC system with favorable dynamic performance
and realizes the perfect combination between sub-module capacitor voltage balancing and circulation inhibition. Finally
two-end 401 level MMC-HVDC simulation model is established in PSCAD/EMTDC. Moreover
401 kinds of composite states of MPC model of traditional voltage sequencing are decreased to 36 kinds through SSPFM-MPC. The dynamic response of system is favorable
which effectively verifies the correctness of the proposed method.
