Novel Hybrid Photovoltaic Array Arrangement to Mitigate Partial Shading Effects

This paper presents a Novel Hybrid reconfiguration scheme to mitigate partial shading effects in the photovoltaic array and minimize ties number and wiring complexity. The proposed topology is based on a combination of Total-Cross-Tied and Bridge-Linked classic topologies. Ten possible shadowing scenarios have been considered for this investigation in 6x6 photovoltaic array. Further, the proposed topology performance is assessed and compared to various typical photovoltaic array topologies, namely, Series-Parallel (S‑P), Honey-Comb (H-C), Bridge-Linked (B-L), and Total-Cross-Tied (T-C-T) by considering the several parameters like Global Maximum Power Point (GMPP), Current at GMPP, Voltage at GMPP, Fill Factor, Mismatch Loss, and Efficiency. The Canadian Solar CS5A-200M PV module parameters are used in MATLAB-Simulink software to simulate photovoltaic array configurations. Finally, the findings of this work demonstrates that the suggested topology minimizes the shading losses and generates the highest maximum power regarding the other array configurations under most shadowing cases. The power enhancement percentage of the Novel arrangement can reach up to 20.25% for the S-P configuration, and up to 16% for both the H-C and B-L topologies. In addition, the proposed scheme is characterized by the minimum wiring loss when compared to the Total-Cross-Tied topology.
