摘要：
In this paper, in order to solve the problem that the conventional MPC cannot obtain excellent performance for short of enough switching states. A novel model predictive current control strategy for single-phase grid-connected inverter without coordinate transformation is proposed. In order to get better control performance, the switching state set is extended by introducing virtual switching state in this study. To improve efficiency, a scheme to reduce the switching frequency is proposed. Subsequently, for facilitate the online modification and practical application of the algorithm, a universal algorithm model is proposed. Finally, the effectiveness of the proposed MPC strategy is verified by simulation using MAT LAB/Simulink.
