Abstract The low relative position of the fixed PV arrays can lead to the mutual shading between them. This shading decreases the overall energy produced by PV systems due to the mismatch losses. In this paper, the fixed reconfiguration technique is optimized bases on Sudoku puzzle pattern to reduce the effects of this shading. In the optimized technique, the physical location of modules in a total cross tied (TCT) connected PV array are rearranged based on new modified Sudoku dispersion rules. For this purpose, the mutual shadow (MSH) pattern is initially determined in the PV plants that have collectors with the same tilt and direction. Then, the weaknesses of the usual Sudoku dispersion rules against these shadows are explained and the MSHs that can lead to the non-optimal conditions are presented. For optimization of the Sudoku-based reconfiguration technique, the new rules will be merged to the usual Sudoku dispersion rules. Finally, the improvement resulting from the modified technique with respect to the non-modified and some other methods is demonstrated by extensive simulation results.

基于数独的重配置技术在相互遮蔽条件下增强光伏阵列功率的优化

摘要 固定式光伏阵列相对位置较低，会导致它们之间相互遮蔽。由于失配损失，这种遮蔽降低了光伏系统产生的总能量。在本文中，固定重配置技术基于数独拼图模式进行优化，以减少这种阴影的影响。在优化技术中，总交叉连接 (TCT) 连接的光伏阵列中模块的物理位置根据新修改的数独分散规则重新排列。为此，最初在具有相同倾斜和方向的收集器的光伏电站中确定互影 (MSH) 模式。然后，解释了针对这些阴影的通常数独分散规则的弱点，并介绍了可能导致非最佳条件的 MSH。为了优化基于数独的重新配置技术，新规则将合并到通常的数独分散规则中。最后，大量的模拟结果证明了改进技术相对于未改进方法和其他一些方法的改进。
