Cross kit reconfiguration algorithm for enhanced output power of PV array during shading mismatch conditions

Abstract

Maintaining the uniform irradiance in an extensive photovoltaic (PV) system is almost impossible. The mismatch between panels of a PV array results in substantial power loss. The PV panels in an array are reconfigured by the proposed Cross-Kit (CK) technique to obtain optimal power output for different partial shade situations (PSS). The suggested approach allows the structure to balance the shade effect across the entire PV array with different physical places of panels. The PV modules are linked using the Total Cross Tied (TCT) configuration, and the CK technique decides the physical placement of modules within the array. The electrical connections of the TCT-linked PV array are unaffected by the CK panel configurations. The PV array’s output arranged with the suggested CK method is assessed and contrasted with TCT and Odd-Even (OE) reconfiguration for mathematical and experimental validation. Four different PSS are taken into consideration. The percentage instantaneous maximum power improvement compared to TCT and OE ranges from 5.49% to 26.73%. The benefits of the suggested approach include straightforward guidelines for implementation, explanation of the P-V plots, and a reduced charge of maximum power point tracking.
