| Popis: | During Partial Shading (PS) condition, Solar Photovoltaic (SPV) array exhibits multiple peaks in both Power-voltage and Current-voltage characteristics, leading to Mismatch Power Losses (MPL). Overcoming the losses, enhancing power and performance improvement of SPV array during PS conditions is a challenging task. MPL due to PS condition, not only depend on the shaded area, but also on SPV array Interconnections and Shading Patterns. The present investigation aims to enhance the output power of SPV array subjected to PS conditions. Studies are initially performed on eight combinations of SPV array test panel interconnections. Results obtained imply improved performance of the ‘Proposed New Reconfigured Hybrid interconnected array’ under four defined different typical partial shading conditions. Also, performance of ‘Proposed New Hybrid interconnected array’ with ‘Shade Dispersion Magic Square Puzzle Pattern’ technique applied is shown to be superior, compared with either SUDUKO or ODD-EVEN shade dispersion technique. |
