摘要:

光伏(PV)阵列在部分遮挡条件(PSC)下的P-V特性具有多个峰值,传统的最大功率点跟踪(MPPT)算法在区分局部峰值和全局峰值方面智能不足,可能无法跟踪全局最大功率点(GMPP)。提出了一种新的快速MPPT方法,实现了所有PSC下光伏阵列的GMPP。该方法在全面研究光伏阵列I-V和P-V特性的基础上,减少了所需的样本数量,提高了GMPP跟踪的速度。所提出的方法的性能进行了评估,在不同的PSC的模拟。此外,它的性能进行了比较,与两个选定的方法在文献中通过模拟。比较突出了所提出的方法的优越性。

英文摘要:

P-V characteristic of photovoltaic (PV) arrays under partially shaded conditions (PSC) has multiple peaks, and conventional maximum power point tracking (MPPT) algorithms may fail to track the global maximum power point (GMPP) because of their insufficient intelligence in discriminating the local and global peaks. This paper proposes a novel fast MPPT method to achieve GMPP of PV array under all PSCs. The proposed method reduces the number of required samples and increases the speed of GMPP tracking based on comprehensive study of I-V and P-V characteristics of PV array. Performance of the proposed method has been evaluated in simulations of different PSCs. Also, its performance has been compared with two selected methods in the literature through simulations. Comparisons highlight the superiority of the proposed method.
