摘要

对于部分遮阳的光伏阵列，在最大功率点(MPP)特性中将有几个峰值。传统的增量电导(INC)算法无法提取阴影过程中的全局最大功率点。因此，对INC算法进行了一些修改，以在最恶劣的大气条件下提取全局最大值点。混合Cuk变换器的性能优于Cuk和升压变换器。该算法在混合型Cuk变换器上进行了实验。本文介绍了Cuk变换器在面板部分遮挡时，采用改进的INC算法产生开关脉冲以提取最大功率的性能。将改进算法的结果与基本增量电导算法进行了比较。

A modified incremental conductance algorithm for partially shaded PV array

For a partially shaded PV array there will be several peaks in the Maximum Power Point (MPP) characteristics. The conventional Incremental Conductance (INC) algorithm cannot extract global maximum power point during shading. Therefore the INC algorithm is slightly modified to extract global maximum point during worst atmospheric conditions. Hybrid Cuk converter performance is better compared to Cuk and boost converters. The algorithm is experiment on Hybrid Cuk converter. This paper presents the performance of Cuk converter by applying modified INC algorithm to generate the switching pulses to extract maximum power when the panel is partially shaded. The results of the modified algorithm are compared with basic incremental conductance algorithm.
