Abstract A novel model predictive control (MPC) method is proposed base on mathematical model of the three-phase photovoltaic grid-connected inverters and the principle of MPC in this paper. The predictive model is acquired from the first-order difference equation of the inverter, then value of future sample cycles can be predictive, finally, the optimal control variables can be obtained by the rolling optimization, it has excellent performances and with hard robustness. The implementation process of the proposed method is described in detail, and the simulation model is established by Matlab/Simulink. The results of simulation proved that the proposed MPC control method has a quick response and with hard robustness, it’s very suitable for the PV inverter control in high-performance occasions.
