Abstract
A review of literature in the area of modeling and simulation of solar photovoltaic (PV) systems shows that there are a number of models that are equivalent to each other in terms of matching of performance characteristics with an ideal PV panel of the same rating. Researchers have different opinions regarding the simulation of PV panel models but none of them suggest which model is the best for implementation in less time and offers the flexibility to change the model parameters for further analysis of PV panel behavior. Hence, the starting phase of research consumes more time to select the best model of PV panel for simulation and analysis. This paper aims to help researchers to get an idea about the different types of simulation models of PV panels that are described in the literature or available in MATLAB software and save time for model selection when starting their research work. In this paper, four different types of PV Simulink models have been selected for study from the ones available in the literature and one PV model has been proposed. The datasheet parameters of PV panel KC200GT manufactured by Kyocera Corporation, Japan are used as a reference for all five Simulink models. All the five models were implemented in MATLAB software and a comparison of their output electrical characteristics has been carried out for the same operating conditions. It was found that the performance of the proposed model is comparable with the best ones available in the literature, while the time required for its simulation is lesser. The importance of this study lies in improving the accuracy of modeling and simulation process of PV systems and in serving as a guideline for beginners in this area of research.
