摘要
为提高光伏阵列发电效率,避免发生热斑效应,通过改进空间向量模型,对局部阴影下光伏组件间的匹配度进行计算,并将匹配度高的光伏组件进行串联,实现对光伏阵列结构的优化。对比分析表明,该算法可提高光伏阵列输出功率,提高组件间的匹配度,避免因不匹配而造成的热斑问题。
To improve the efficiency of PV generation system, and avoid hot spot effect, the improvement was made based on the vector space model. The matching degree between PV modules under parti:d shade was calculated, and PV modules with high matching degree were connected in series to optimize the structure of the PV array. Comparative analysis shows that the algorithm can increase the output power of the PV array under partial shading, improve the matching degree between PV modules, and avoid the hot spot problem caused by mismatch.
