Successive rotation approach based novel game puzzles for higher shade dispersion of PV array systems under non-uniform irradiations

Abstract

Obstructed irradiation negatively impacts solar PV performance and raises issues of power loss (PL). In the partial shading conditions (PSCs), each row in the PV system has a distinct current production capability under the adverse shadowing effects, which is caused to introduce multiple power peaks known as GMPP and LMPP on the power-voltage (P-V) curves. The MPP tracking device is misleading during adverse irradiation circumstances due to numerous power maxima points. The array system adopted a realignment strategy to boost the PV system's resiliency under the shading mentioned earlier. In this paper, a novelphysical relocationapproach depends onthe 'Successive Rotation Approach' (SRA) based novel game puzzle, which illustrates high GMPP better performanceunder PSCs. The present study suggests that the SRA puzzle-based PVmodule restructuring methodology has a more significant shade dispersion factor (SDF) capability compared to traditional arrangements such as SP, TCT, SDK, and I-SDK, thus reducing PL and optimizing positions of GMPP. An experimental system is developed to validate the MATLAB/Simulink-based results, which proves the close agreement under similar realistic shading situations. In addition to this, the temperature effect due to shading is ivestigated and non-symmetric (6 × 9) PV array configurations are considered for performance evaluation through experimental work.
