Comprehensive Modeling and Simulation of PV Module and Different PV Array Configurations Under Partial Shading Condition

This paper presents the comprehensive modeling and simulation of photovoltaic (PV) module and different PV array configurations to analyze their performances under partial shading condition. In addition, four compound PV array configurations: Series Parallel-Total Cross Tied, Bridge Linked-Total Cross Tied, Honey Comb-Total Cross Tied, and Bridge Linked-Honey Comb have also been proposed in this paper. The comprehensive modeling, which facilitates its simulation with the help of any software, is competent in producing the I-V and P-V characteristics of PV module and different PV array configurations of any size, composed of any variety of PV cells and modules, having any quantity of bypass diodes, and for any environmental condition. The output characteristics and the analogous results produced by MATLAB simulation of proposed models of the module and the above-mentioned array configurations under uniform irradiance condition and partial shading condition with and without bypass diodes have been examined. The experimental validation of the proposed modeling has also been accomplished on the SPM30 PV module and array composed of four HSTBF24265P PV modules. Furthermore, the performances of different PV array configurations ((i) basic configurations: Series, Parallel, Series-Parallel, Total Cross Tied, Bridge Linked, Honey Comb and (ii) proposed compound configurations) have been judged by evaluating their maximum powers, fill factors, thermal voltages, and relative power losses under partial shading condition corresponding to two shading patterns. The simulation results of different PV array configurations for all the considered shading patterns have been analyzed utilizing cumulative distribution function, which confirms the supremacy of the proposed compound configurations over their respective basic configurations.
