Modelling of Solar Cell Considering One Diode Model in MATLAB/Simulink Environment

This study investigates simulation of a photovoltaic cell in MATLAB/Simulink environment keeping in view one diode model of the same. Performance analysis of a photovoltaic (PV) module/array is carried with the help of simulation results. Based on an equivalent circuit model and existing mathematical model validation is carried out in this study. Output characteristics of solar cell represents maximum power point under different environmental conditions. This chapter investigates simulation of a photovoltaic cell in MATLAB/Simulink environment keeping in view one diode model of the same. A mathematical model of solar cell is developed and simulated in MATLAB/Simulink environment based on existing one diode model and its mathematical equations. Even in MATLAB, solar cells can be modelled using several methods such as mathematical block modelling, embedded MATLAB programming, and physical block modelling. There are several software packages which are utilized to analyse solar cells such as MATLAB, PSPICE. The behaviour of the Simulink model was validated and implemented in MATLAB environment. Output power from a solar cell depends on variation in different weather conditions such as temperature and shading. So, if the performance or specific output of a solar cell is known at any particular temperature and at particular radiation, then its performance can be predicted at another temperature with suitable accuracy.
