摘要

提高光伏电池的发电效率一直是学者们研究的重点，MPPT 技术保证光伏发电系统持续工作在最大功率点附近，从而提高发电效率。面对不均匀光照下Ｐ?Ｕ曲线的多峰现象，传统 MPPT 算法难以找到最大功率点 GMPP，容易陷入局部峰值点 LMPP，学者们后续提出新的 MPPT 算法仍存在一定缺陷，无法简单有效且准确地追踪 GMPP。本文针对上述问题，通过 Simulink 软件搭建仿真模型来研究不均匀光照下光伏阵列的输出特性，希望对学者后续改进 MPPT 算法和布置光伏阵列提供帮助与启发。

Abstract:

lmproving the power generation efficiency of photovoltaic batteries has always been the focus ofscholars' researeh.The MPPT technology guarantees that the photovoltaie power generation system continues towork near the maximum power point , thereby improving the efficiency of power generation. Ffaced with themulti-peak phenomenon of the P-U curve under uneven light ,it is diffieult for the traditional MPPT algorithmto find the maximum power point GMPP , which is easy to fall into the local peak point LMPp.In response tothe above problems , the simulation model of Simulink software is used to study the output characteristies of thephotovoltaic array under uneven light.It is hoped that the study will help and inspire the MPPT algorithm andthe arrangement of the photovoltaie array.

Key words: photovoltaic array uneven illumination Simulink MPPT
