Abstract

Highlights: Comparison of existing SP, TCT, SDK, I-SDK configurations (9 × 9 size) with novel SRA puzzles based configurations. Higher shade dispersion attained using the proposed SRA configuration under PSCs. Performance indices e.g. GMPP, FF, PL, %PR and %PG carried out during four shading scenarios. Experimental study is carried out to validate and feasibility of the proposed system under PSCs. 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 novel physical relocation approach depends on the 'Successive Rotation Approach' (SRA) based novel game puzzle, which illustrates high GMPP better performance under PSCs. The present study suggests that the SRA puzzle-based PV module 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.
