Line losses reduction techniques in puzzled PV array configuration under different shading conditions

The SuDoKu puzzled (SDKP) configuration is a technique to magnify the execution of PV array due to the occurrence of partial shading conditions (PSCs) but more wiring losses exit in this array. This paper focuses on both in terms of power enhancement and wiring loss reduction of PV arrays under PSCs. Moreover, performance of the existing SDKP configuration is contrasted with the proposed Latin Square puzzled (LSP) and Ken-Ken Square puzzled (KKSP) based configurations to moderate the effects of shading situations. An investigation is carried out based on considered various ranges of shading situations such as short narrow, long narrow, short wide and long wide in terms of power generation, power dissipated, execution ratio and fill factor of PV arrays. Further, it is shown that power generation in the proposed configuration is 6.81% more as compared to SDKP configuration. The wiring loss is found to be 18.86% minimum while power loss is 771 W less in the proposed configuration as compared to SDKP configuration under the considered shading situations. Overall, execution of the proposed KKSP configuration is found to be superior to the SDKP configuration.
