Abstract

In this paper, a finite control set model predictive control (FCS-MPC) based on simplified calculation and sector selection optimization is proposed for three-phase three-level T-grid-connected inverters. Firstly, the sector is divided according to the radiation range of the voltage vector. Then, in order to optimize the problem of excessive calculation caused by the new sector division, the secondary judgment is carried out in the sector selection, and the voltage vector is combined to a certain extent, which not only promotes the neutral point potential balance but also reduces the total harmonic distortion. Finally, the proposed FCS-MPC is simulated to verify the effectiveness of the proposed method.

Keywords

finite control set model predictive control, sector selection optimization, simplified calculation.
