A PSO algorithm for the calculation of the series and shunt resistances of the PV panel one-diode model

Different equivalent circuit models can be found in the literature to describe the electrical performance of PV panels. Among all the models, the one diode models are widely used. However the determination of the electrical parameters of these models is not an easy task. In this paper, the particle swarm optimization (PSO) method was applied to extract the equivalent circuit parameters of PV panels. The PSO method was implemented in Matlab to calculate the series and shunt resistances of two modified one-diode models used to determine the electrical performance of a photovoltaic panel. The PSO method allowed us to plot I-V curves close to those provided by the PV manufacturer and proved to be a good approach capable of working with any electrical model.
