太阳能电池的MPPT算法仿真研究

Research on MPPT Algorithm Simulation of Solar Cells

太阳能电池的作用是将光能转换成电能,对其工作要求是高效电能输出,但其功率输出会受到日照强度、器件结温的影响。研究太阳能电池在各不同环境因素下的转换效率,并通过调节控制使太阳能电池保持在最大能量转换率是光伏发电系统的核心技术,又称为最大功率点跟踪(MPPT)问题。本文分析研究了几种常用的MPPT算法,并通过仿真进行研究比较,最后提出了自适应电导增量法。

In its conversion of light energy into electric energy,solar cells have to meet the working requirement of high efficient power output which will be affected by the intensity of sunlight and the device junction temperature. This paper studies the conversion efficiency of solar cells under various environmental factors,and keeps the cells at the maximum conversion rate through adjusting and controlling which is the core technique of photovoltaic power generation system,also known as the maximum power point tracking(MPPT) problem. This paper studies and analyzes some common MPPT algorithms,and compares through simulation,and finally puts forward the adaptive incremental conductance method.
