Abstract

The photovoltaic (PV) module parameters extraction for the PV modelling and simulation, are very important for the development, improvement, and control of the PV systems. This paper proposes a novel industrial automation programmable logic controller (PLC) based modelling using the single diode model. The main contributions of this work are: a) geometrical PV cell parameters extraction; b) PV modelling using automation PLC software. To validate the accuracy of the proposed approach, the extracted parameters will be compared to those extracted in previous studies of a multi-crystalline PV module, and to validate the PV modelling using automation software, the current-voltage (I-V) curves and the power-voltage (P-V) curves for several irradiation levels at 25°C will be plotted and evaluated. The characteristic curves are plotted using the automation human-machine interface (PLC-HMI). The results reveal that the automation PLC through the PV block presents a very good modelling of the PV module that can be used as an input for any PV system.
