摘要

摘要 部分遮光已被证明会对太阳能光伏系统的功率输出产生负面影响。当光伏系统的一部分被遮挡,而系统的其余部分完全照亮时,就会出现这种情况。部分遮挡干扰了具有单功率峰值的功率曲线的规则形状,产生了具有多个功率峰值的功率曲线。目前已有许多爬坡算法,但它们通常无法在全局功率峰值上进行操作,而是会停留在某个局部峰值上,从而造成功率损失。本文推导出一组简单方程,用于估算部分遮挡模块的功率峰值,然后利用这些方程开发出一种全局功率峰值跟踪方法。与现有方法不同,本文提出的方法实施起来非常简单,不需要复杂的模型或特殊函数。通过模拟和实验进行了广泛的验证和确认。结果表明,所提出的方法可以通过确保全局功率峰值提取来提高太阳能光伏系统的发电量。

A Simple Technique for the Global Power Peak Tracking in Partially Shaded Solar Systems

Partial shading has been shown to negatively affect the power output of solar PV systems. It occurs when part of a PV system is shaded while the rest of the system is fully illuminated. Partial shading disturbs the regular shape of the power curve that has single-power peak and produces power curve with multiple power peaks. Numerous hill-climbing algorithms exist, however they usually miss the operation on the global power peak and instead get stuck in one of the local peaks resulting in power losses. This paper derives a set of simple equations estimating the power peaks of partially shaded modules which are then utilized to develop a method for global power peak tracking. Unlike existing approaches, the proposed approach is very simple for implementation and does not require intricate models or special functions. Extensive verifications and validations are provided through simulations and experimentally. The results show that the proposed method can increase the power generation of solar PV systems through ensuring the global power peak extraction.
