传统的最大功率跟踪算法，都是在光伏组件光照强度均匀的前提下提出的。但是，实际情况中光伏组件会部分被遮挡，P—V曲线产生多个峰值点，使得现有算法跟踪失败。研究部分遮挡情况下，光伏组件的I—V，P—V特性曲线，并提出一种适用于遮挡情况下的最大功率点算法。

Conventional maximum power pointing tracking （mppt） methods are effective under uniform so- lar irradiance. However, PV models can be partially shaded under some conditions, and the output-current curve will have several local maximum power points, and that makes conven- tional algorithms fail to track. Analyses I-V and P-V characteristics of the PV modules under partially shaded conditions, and proposes a novel MPPT method capable of tracking real MPPT.
