Abstract
This paper presents a comprehensive comparative analysis study for various kinds of single diode models based photovoltaic power source. The effect of increasing the embedded degree of complexity of the single diode model is explored by comparing the dynamic performance of particular PV modules with the experimental validated data under varying the atmospheric conditions. The main motivation for this work is to determine an accurate and less complicated PV single diode model that is suitable for correctly characterize the PV systems under all environmental conditions and that can be efficiently used in any power system study especially those targeting maximum power point tracking. The relative errors between each PV single diode model output and the experimentally validated data are computed at three indicative points namely open circuit voltage, short circuit current and maximum power point. The comparison study in this paper ends up with determining the relevant single diode model at low, medium and high temperature and irradiance level as well as at standard test conditions.
