摘要:
外界环境温度和光照强度等因素直接影响着光伏阵列的输出特性，如果能够使光伏电池一直工作于最大功率输出状态，就可以大大提高太阳能的利用率。本文介绍了当前常用的几种光伏电池最大功率点追踪(maximum power point tracking, MPPT)方法，论述了一种基于双向Cuk变换器电路对光伏电池进行MPPT的方法，利用Matlab/Simulink仿真平台对光伏发电系统的整体结构进行了仿真，仿真结果表明了该方法的可行性。
The output of photovoltaic (PV) array is influenced by the environmental factors such as irradia-tion and temperature, if we can make sure that the photovoltaic array operates at the maximum power point, solar energy can get a high utilization rate. This paper introduces a variety of com-mon photovoltaic maximum power point tracking (MPPT) methods, discusses one using of a bidirectional Cuk converter method for MPPT of photovoltaic cells, through the simulation of photovoltaic system based on the Matlab/Simulink platform, the results verify the feasibility of this method.
