ANFIS-based parameter estimation of one-diode equivalent circuit model of PV modules

Fast implementation and accurate operation of maximum power point tracking (MPPT) controllers can be realized by modeling the characteristics of PV modules obtaining equivalent parameters. In this study, ANFIS has been used to obtain three of the parameters in single-diode model of PV cells namely series resistance, shunt resistance and diode ideality factor. The input parameters of ANFIS are material type of PV modules, short circuit current, open circuit voltage, and unit area under I-V curve of PV module. The advantage of the proposed method is that the equivalent parameters can be obtained for a wide range of PV modules of different types (mono-crystalline, multi-crystalline and thin-film) using easily obtainable field test data. The simulation results suggest that, ANFIS model can be a useful tool for estimating equivalent parameters of PV modules.
