摘要

This study presents a robust technique to estimate the maximum power point (MPP) of a double-diode model (DDM) photovoltaic (PV) module. The MPP of the DDM PV module under different environmental conditions (DECs) are estimated by using the simple and computationally efficient Levenberg–Marquardt method. The variation of double diode PV module parameters with the change of temperature and irradiation is analysed. The MPP of the DDM PV array at non-standard test condition obtained from the proposed method is verified with the MPP obtained experimentally and by MATLAB simulation. A comparative study of MPP of a DDM PV module estimated from the proposed method with different existing methods is performed for different operating conditions. The maximum measurement error in power generation of a DDM PV module for different methods under DEC is presented which indicates better performance of the proposed method for the estimation of MPP of a DDM PV module.
