Peak Power Enhancement by Novel Reconfiguration Scheme of a Solar Model Under Realistic Partial Shading Conditions

Metrological factors such as irradiation level and temperature adversely affect the healthy functioning of solar arrays. It leads to the generation of local peaks on the output power-voltage (P-V) curve of the solar model. Hence, to mitigate this complex issue a novel calcudoku (N-C) reconfiguration of solar arrays is proposed in this paper. It uses a two-diode model built using the MATLAB/SIMULINK tool. The effectiveness of the novel calcudoku is tested under four different shadings. Its performance is compared with the traditional total cross-tied (TCT) and advanced odd-even (O-E) solar reconfigured models. Results show that the novel 4$\times$ 4 calcudoku has improved peak power by S.61W and 3. 43W under regional shading, increased efficiency by 0.27% and 0.49% under mixed shadings, and has substantially reduced the shading loss by 5.15% and 1.74% under inverted-U shading concerning total cross-tied and odd-even solar reconfigured model. Thus, the novel proposed calcudoku reconfigured solar model excel in effective shade dispersion with regard to the other considered models.
