MATLAB Modeling and Simulation of Photovoltaic Modules
Abstract:
In this paper a modeling method is investigated that finds the non-linear equation parameters of a photovoltaic (PV) module in order to obtain the desired PV model using any circuit simulator. This modeling method adjusts the I-V curve at three remarkable points: the open circuit voltage, the short circuit current, and the maximum power point [1]. Three models are realized using this technique namely, the single-diode model, the two-diode model, and the three-diode model. The evaluation study of the accuracy of these three models showed relative errors ranging from 32% to 50%. Further, this technique is improved by adjusting the I-V curve at more than three points depending on the number of unknowns to be found for each model, which showed a reduction in the relative error ranging from 0.37% to 38%.
