- A novel MPPT controller in a PV grid connected system is proposed by considering both 2L-VSI and 3L-VSI topologies.
- The proposed controller is developed using the MPC technique combined with the modified incremental conductance algorithm.
- A predictive model selects the switches states in order to minimize errors of active and reactive power predictions.
- Predictions are evaluated according to predefined cost functions according to the type of horizon prediction.
- Experimental results are provided to show the effectiveness of the proposed control method using data picked from a real PV module for varying atmospheric conditions.
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.
