VALOUCH, V. and P. SIMEK. Comparison of predictive direct power control methods for grid-connected converter in B4 configuration. In: 2019 International Conference on Electrical Drives & Power Electronics (EDPE). Nový Smokovec, The High Tatras, 2019-09-24/2019-09-26. Košice: Technical University of Košice, 2019. p. 87-92.

A model predictive direct power control of the three-phase converter with only four converter branches (B4) connected to an unbalanced grid is introduced. The developed infinite-control-set and usual finite-control-set MP DPC strategies are presented. The relations for predicted powers are developed in the form enabling analytical solution of the selected objective function for the infinite-control-set MP DPC. The alternative instantaneous non-active power theory is used, which preserves harmonic free grid currents not only for a symmetrical but also unsymmetrical voltage system. Simulation results for the L grid filter are presented, analyzed and compared for both the option of the MP DPC.
