摘要: 光伏电池随环境温度和光照强度变化时的输出特性具有明显的非线性特征,其输出功率会随着负载的变化而变化,为了快速准确地找到最大功率点,文中采用干扰观察法在Matlab中建立了光伏电池阵列模型,提出一种改进的MPPT方法,通过仿真和定步长干扰观察法进行了比对,发现改进的MPPT方法迭代次数明显较少,且能快速找到最大功率点。

Abstract: A nonlinear variation of the output power of photovoltaic cells with the load is obvious as the ambient temperature and light intensity change.How to find the maximum power point rapidly and exactly is becoming a research hotspot.This article employs the disturbance observation method to study the maximum power point,and photovoltaic array model is established in the Matlab with an improved MPPT method.Comparison with the fixed step disturbance observation method by simulation shows that the improved MPPT method has significantly fewer iteration times with quicker determination of the maximum power point.

Key words: solar energy;characteristic of photovoltaic battery;MPPT
