| Abstract: | Finite set model predictive control applied to high-power grid-connected inverters can reduce the switching frequency while controlling the grid-connected current. However, as the switching frequency decreases, the harmonics of the grid-connected current become significantly larger. Aiming at this problem, an improved finite set model predictive control method with a new harmonic suppression strategy is proposed. The objective of harmonic suppression is added to the multi-objective optimization process of finite set model predictive control. The suppression strategy is realized by extracting the harmonic amplitude based on the orthogonality of the trigonometric function. The proposed method reduces the harmonic content of the grid-connected current at the same low switching frequency some as the traditional method, thereby improving the quality of the grid-connected current. Finally, the effectiveness of the proposed method is verified by experiment. |
