Control of PV grid connected systems using MPC technique and different inverter configuration models.

This paper addresses the control problem of a PV power generating chain such that the maximum power is provided to the grid connected system without the need of any additional module stages. For this purpose, the proposed control system is directly applied to the power inverter using power-MOS switches, for which, a prediction-based model selects the switch state while minimizing the error between actual and predicted power outputs. Obtained predictions are evaluated using a cost function. Attention is paid in this paper to the validation of the proposed control method using one and two steps future predictions. Finally, simulation results are provided to demonstrate the effectiveness of the proposed control methodology. [ABSTRACT FROM AUTHOR]
