MODELING AND SIMULATION BASED APPROACH OF PHOTOVOLTAIC SYSTEM IN SIMULINK MODEL

This paper presents the modeling and simulation of photovoltaic model using MATLAB/Simulink software package. The proposed model is design with a user-friendly icon using Simpower of Simulink block libraries. Taking the effect of irradiance and temperature into consideration, the output current and power characteristic of PV model are simulated using the proposed model. Detailed modeling procedure for the circuit model with numerical values is presented. The simulator is verified by applying the model to 36 W PV modules. The proposed model was found to be better and accurate for any irradiance and temperature variations. The proposed model can be very useful for PV Engineers and expert who require a simple, fast and accurate PV simulator to design their systems.
