Generalized modelling of PV module and different PV array configurations under partial shading condition

This paper proposes generalized modelling of photovoltaic (PV) module and different PV array configurations -(i) conventional configurations: Series, Parallel, Series-Parallel, Total-Cross-Tied, Bridge-Linked, Honey-Comb and (ii) hybrid configurations: Series Parallel -Total Cross Tied, Bridge Linked -Total Cross Tied, Honey Comb -Total Cross Tied, Bridge Linked -Honey Comb under partial shading condition. The projected modelling is fully efficient in determining the detailed output graphs of PV module and different PV array configurations of whichever rating, synthesized of any class of PV cell or module, and for every probable real-time partially shaded situation. The presented modelling can accomplish this objective by merely exploiting the information given in the catalogue released by manufacturers. The results obtained by the execution of MATLAB codes of the proposed equations for the module and the aforesaid array configurations under uniform irradiance condition and partial shading condition in presence and absence of bypass diodes have been investigated on the basis of their maximum power, fill-factor, thermal voltage, and relative power loss and authenticated by MATLAB simulation. The proposed modelling has also been practically verified on the ZONHAN PV module and array made of four WS-330 PV modules.
