摘要
在光伏发电系统中,光伏电池输出特性受光照强度及环境温度影响很大,具有明显的非线性特征。因此,需要对光伏电池的最大功率点进行跟踪控制。文章简单介绍了几种常用的最大功率跟踪方法,分析比较了各自的优缺点,并提出了一种改进的最大功率跟踪控制方法,通过仿真实验验证了该方法的正确性。
In photovoltaic system, the output of photovoltaic battery is affected greatly by the light intensity and environment temperature, it has obvious non - linear features. Therefore, it needs to track and control the Maximum Power Point for photovoltaic battery. The article introduces several existing MPPT, analyzes and compares the advantages and weaknesses of these methods, and proposes an improved method of the MPPT, proves the correctness of the method through the simulation.
