A STUDY ON MODELLING AND SIMULATION OF PHOTOVOLTAIC CELLS

This Paper presents a detailed study on the types of modelling of the PV Panel for simulation studies. The main concern of this study is to analyze the results and compare them under standard test conditions. PV systems are generally integrated with specific control algorithms in order to extract the maximum possible power. Hence it is highly imperative that the Maximum Power Point (MPP) is achieved effectively and thus we need to design a model from which the MPPT algorithm can be realized in an efficient way. Also other parameters should be taken into account for finding the best model for the use in simulation. It is very important to choose the appropriate model based on the application. The models used for study in this paper include the single diode model, two diode model and Simscape modelling. MATLAB/Simulink presents a powerful tool to study such systems. The work tests the accuracy of the models under different temperature and irradiance conditions. The two diode model is known to have better accuracy at low irradiance levels which allows for a more accurate prediction of PV system performance. Simscape, part of Simulink environment, has a solar cell block that makes building a PV model straightforward and much easier programming with full demonstration to all system details. On the basis of the study, the best model that can be used for simulation purposes can be selected. It is envisaged that the work can be very useful for professionals who require simple and accurate PV simulators for their design. All the systems here are modeled and simulated in MATLAB/Simulink environment.

SIMULATION AND CHARACTERISTICS STUDY OF SOLAR PHOTOVOLTAIC ARRAY USING MATLAB/SIMULINK

AL-Taqani Journal, 2016

The study of Photovoltaic (PV) systems in an efficient manner requires a precise knowledge of the I-V and P-V characteristic curves of solar PV array. Therefore, this paper presents modelling and simulation of solar PV module using Matlab/Simulink. This model is based on mathematical equations and is described through an equivalent circuit including a photo current source, diode, shunt resistor expressing leakage current and series resistor represents the internal losses due to the current flow. The developed model allows the prediction of PV array behaviour under different circuit model and environmental parameters (temperature, and solar radiation).A particular typical 175Watt solar panel was used for model evaluation, and results was compared with points taken directly from the manufacturer's published curves and show excellent correspondence to the model. Keyword: PV cell, PV array, I-V and P-V characteristic.

Mathematical Modeling of different Photovoltaic Modules

— This paper presents a mathematical model for solar Photovoltaic (PV) cells and compares their performance to an existing model in renewable energy research center (RERC) at the University of Anbar-Iraq. The model is able to simulate both the I-V characteristics curves and the P-V characteristics curves and it is used to study different parameters variations that can affect on the PV array performance including operating temperature and solar irradiance level. The results of the PV characteristics curves are compared to the curves provided by Kyocera PV and Solara PV model datasheets. The results are extracted and simulated using the Matlab software. One-diode equivalent circuit is employed in order to investigate I-V and P-V characteristics of a typical 54 W and 100W solar modules. The simulation results will be used as a reference to compare the performance of both models under a dusty weather and also for comparing their performances by using the solar module simulator in our future work.
