摘要

This paper analyses the performances of dissimilar $PV$ $PV$ array topologies—(i) classical topologies: ${\text{Series}}$ $Series$ , ${\text{Parallel}}$ $Parallel$ , Series–Parallel, ${\text{Total-Cross-Tied}}$ $Total-Cross-Tied$ , ${\text{Bridge}}-{\text{Linked}}$ $Bridge - Linked$ , $\mathrm{and Honey}-{\text{Comb}}$ $and Honey - Comb$ and (ii) modern topologies: $\mathrm{Series\, Parallel}-\mathrm{Total\, Cross\, Tied}$ $Series Parallel - Total Cross Tied$ , $\mathrm{Bridge\, Linked}-\mathrm{Total\, Cross\, Tied}$ $Bridge Linked - Total Cross Tied$ , $\mathrm{Honey\, Comb}-\mathrm{Total\, Cross\, Tied}$ $Honey Comb - Total Cross Tied$ , and $\mathrm{Bridge\, Linked}-\mathrm{Honey\, Comb}$ $Bridge Linked - Honey Comb$ under realistic $\mathrm{partial\, shading\, condition}$ $partial shading condition$ . In this work, MATLAB tool has been used for the simulation of the models of dissimilar ${\text{PV}}$ $PV$ array topologies. The performances of dissimilar ${\text{PV}}$ $PV$ array topologies have been weighed against each other on the basis of their $\mathrm{maximum\, power}$ $maximum power$ , ${\text{fill}}-{\text{factor}}$ $fill - factor$ , $\mathrm{thermal\, voltage}$ $thermal voltage$ , and $\mathrm{relative\, power\, loss}$ $relative power loss$ under realistic $\mathrm{partial\, shading\, condition}$ $partial shading condition$ analogous to two shading patterns at various instants for respectively 2 complete days 6 months apart. The MATLAB simulated outcomes of dissimilar ${\text{PV}}$ $PV$ array topologies for all the examined shading patterns have been processed employing $\mathrm{probability\, density\, function}$ $probability density function$ which validates the superiority of the modern topologies over their respective classical topologies.
