Modeling and performance analysis of a generalized photovoltaic array in Matlab

A generalized photovoltaic array simulation model in Matlab/Simulink environment is developed and presented in this paper. The model includes PV module and array for easy use on simulation platform. The proposed model is designed with a user-friendly icon and a dialog box like Simulink block libraries. This makes the generalized PV model easily simulated and analyzed even with a maximum power point tracker. Considering the effect of solar irradiance and temperature change, the output current and voltage of PV modules are simulated and optimized using the proposed model. The model was tested using a directly coupled dc load as well as an ac load via an inverter. The test result validates the model which can be used in related research works.
