The solar photovoltaic (PV) array generates the power below the rated value due to the shading intensity and shading pattern losses under partial shading conditions (PSCs). The different levels of solar irradiance are received by the modules of PV array under PSCs; it causes the mismatch between the generated module currents, leading unfortunate impacts such as hot-spot and therefore total PV power generation reduces. Resulting, the efficiency of solar PV array decreases. This article presents the optimal energy harvesting using physical relocation and fixed column position of modules with fixed electrical connection (PRFCPM-FEC) under different shading conditions. The proposed algorithm is presented for ${m} \times {n}$ modules under different shading conditions. The locations of modules are changed according to the proposed configuration without removing the electrical connections. A comparative analysis has also been presented between proposed pattern configuration, total cross tied (TCT), and physical relocation of the modules with a fixed electrical connection (PRM-FEC) configurations. The results demonstrated that the proposed array configuration produced the improved performance under PSCs.

使用阴影色散增强 PSC 下的太阳能光伏发电

由于部分阴影条件 (PSC) 下的阴影强度和阴影图案损失，太阳能光伏 (PV) 阵列产生的功率低于额定值。PSC下的光伏阵列组件接收不同水平的太阳辐照度；它导致产生的组件电流之间的不匹配，导致诸如热点等不利影响，因此光伏总发电量减少。结果，太阳能光伏阵列的效率降低。本文介绍了在不同阴影条件下使用固定电气连接模块的物理重定位和固定柱位置 (PRFCPM-FEC) 的最佳能量收集。提出的算法是针对不同着色条件下的 ${m} \times {n}$ 个模块提出的。模块的位置根据建议的配置进行更改，而无需移除电气连接。还提出了建议的模式配置、总交叉连接 (TCT) 和具有固定电气连接 (PRM-FEC) 配置的模块的物理重定位之间的比较分析。结果表明，所提出的阵列配置在 PSC 下产生了改进的性能。
