In this Letter, the authors present a new analytical method for determining the parameter values for the single‐diode model of photovoltaic (PV) panels. More specifically, the authors propose explicit equations for all the parameters of the model so that their values can be directly extracted from the data provided in the PV panel datasheet. The results show that the proposed method provides smaller errors between the calculated and experimental I–V curves than other analytical approaches.

— In this work, a novel maximum power point tracking algorithm (MPPT) based on Model Predictive Control (MPC) for photovoltaic systems is proposed. The considered system is composed by a photovoltaic panel connected to a load using a flyback converter. The proposed approach combines MPC with a modified Incremental Conductance algorithm with a variable step size, verified in this work to be more efficient than the Perturb and Observe algorithm in tracking maximum power point, making the PV system to generate more energy. Computational simulations are carried out to compare the performance of the considered MPPT algorithms, analyzing the output voltage and output power behavior at the photovoltaic panel. The results of the simulations show that the proposed algorithm provides better performance for the photovoltaic system than the main MPPT algorithms in the literature.
