Model based predictive control with switcher of redundant vectors for a cascade H-bridge multilevel STATCOM

Conventional model based predictive control for cascade H-bridge multilevel STATCOM produces a different switching pattern for different cells. As a consequence, stresses, DC-link imbalance and active power losses are generated among the cells. To solve the aforementioned issues, this paper proposes to include a switcher of redundant vectors on the conventional model based predictive method. Additionally, improve the performance in terms of total harmonic distortion and remain focus the reactive power compensation. Simulation results are analyzed to verify the effectiveness of this proposal.
