摘要
在分析传统的干涉观察算法的基础上,为了克服该方法在光照强度快速变化的情况下会出现误判的缺点,文章引入三点重心比较法的MPPT算法,并针对传统的干涉观察算法跟踪精度和响应速度无法兼顾的缺点提出了变步长算法。通过Matlab/Simulink仿真验证了其优越性,为光伏电池最大输出功率点跟踪的研究提供参考。
On the basis of analyzing the traditional perturb and observe （P＆O） maximum power point tracking algorithm, in order to overcome the shortcoming of that method occurring misjudgment in the case of rapidly changing of irradiance, this paper introduces the MPPT algorithm of three-point weight comparison method, and aiming at the drawbacks of the traditional P＆O method unable to reconcile accuracy and response speed, the paper propose variable step size algorithm. The feasibility of this method is conlirmed by simulation study using software Matlab/Simulink, This paper will provide reference for future work in MPPT study.
