Performance investigation of ShapeDoKu variant for PV formations under realistic assumptions of shading situations

During shading conditions, performance of physical relocation techniques for PV formations is more effective than total cross-tied (TCT) type of PV formation. The main purpose of physical relocation technique is to rearrange the physical position of PV modules in TCT formation without changing the electrical connections. Due to relocation of PV modules, the lengths of required wires are increased. So, the appropriate selection of PV formation is also important. In this paper, three different variants of physical relocation techniques are considered for 6×6 size TCT formation. These three variants are named as SuDoKu (SDK), ShapeDoKu (SPDK) and Futoshiki (FS). Moreover, these variants are analyzed on realistic assumptions of shading situations and these shading situations are categorized into eight different cases. Also, the comparative analysis of PV formations is reported in terms of P-V profiles, effects of shadings on individual rows and generation of energy and incomes. Further, from the obtained results of this paper, it is concluded that these variants of physical relocation techniques enhance the output power, energy and income generation in comparison of TCT type of PV formation. The SPDK variant of physical relocation technique is performing better than the other variants.
