Abstract—Globally, the shading phenomenon has been identified as one of the major issues relating to the successful and effective operation of photovoltaic (PV) system. Shading can be due to neighboring development, passing mists, fowls or winged animals’ litter, etc. that will decrease the generation of PV system. The PV generations under partial shading can be enhanced by suitably selecting PV array configuration and reconfiguration schemes. This article provides an extensive investigation of various PV array configurations and reconfiguration operating in partial shading conditions. The competence with reference to maximum power output, shading losses, fill factor, and mismatch losses of PV array configuration, i.e., Series-Parallel (SP), Honey-Comb (HC), Total Cross Tied (TCT), Bridge-linked (BL), and reconfiguration namely; Odd–Even (OE) are evaluated for four different shading case studies. The results are compared with 7 × 7 PV array configuration for the same shading cases. The investigation is expanded to identify the outcomes of incorporating a bypass diode in each module on power output. The investigations carried out also reveal that the shading scenario decides the maximum instantaneous power output of PV array. The outcomes exhibit that OE reconfiguration provides improved performance concerning to maximum power generation for all considered shading case studies.

部分遮光条件下光伏阵列配置和重构的改进可行性分析

摘要——在全球范围内，阴影现象已被确定为影响光伏 (PV) 系统成功和有效运行的主要问题之一。阴影可能是由于邻近的发展、通过的薄雾、家禽或有翼动物的垫料等会减少光伏系统的发电量。The PV generations under partial shading can be enhanced by suitably selecting PV array configuration and reconfiguration schemes. 本文对在部分遮光条件下运行的各种光伏阵列配置和重新配置进行了广泛调查。参考光伏阵列配置的最大功率输出、遮蔽损失、填充因子和失配损失的能力，即串并联 (SP)、蜂窝 (HC)、总交叉连接 (TCT)、桥接 ( BL)，即重新配置；针对四个不同的阴影案例研究评估了奇偶 (OE)。结果与相同阴影情况下的 7 × 7 光伏阵列配置进行了比较。调查扩展到确定在功率输出的每个模块中加入旁路二极管的结果。进行的调查还表明，遮光方案决定了光伏阵列的最大瞬时功率输出。结果表明，OE 重新配置为所有考虑的阴影案例研究提供了有关最大发电量的改进性能。进行的调查还表明，遮光方案决定了光伏阵列的最大瞬时功率输出。结果表明，OE 重新配置为所有考虑的阴影案例研究提供了有关最大发电量的改进性能。进行的调查还表明，遮光方案决定了光伏阵列的最大瞬时功率输出。结果表明，OE 重新配置为所有考虑的阴影案例研究提供了有关最大发电量的改进性能。
