Novel Dynamic Model of a Photovoltaic Module
Abstract
This paper presents a novel dynamic model of a photovoltaic (PV) module. The two-diode model of a PV module is upgraded with the diodes’ parasitic diffusion and junction capacitances, which are, in turn, modeled as variable parameters. The experimental I-V static characteristics were measured for the monocrystalline PV module, at three different stages of a day. The measured characteristics were compared with the commonly used single- diode and two-diode models of the PV module. The simulation model of the proposed PV model was built in the MATLAB-Simulink environment. Influence of the solar irradiation and the temperature on the parasitic capacitances is shown. Also, dynamic behavior of the PV module is analyzed in simulations.
