摘要

详细讨论了光伏(PV)最大功率点跟踪(MPPT)与物联网集成的设计过程。所需的计算,流行的跟踪算法,和转换器线性的细微差别讨论围绕一个共同的光伏系统拓扑。在MATLAB Simulink中对降压变换器进行了仿真,验证了其在受计算值扰动时的稳定运行。对高分辨率辐照度数据进行统计分析,以提供计算最小占空比摄动步长所需的平均辐照度斜率值。

IoT-based MPPT Controller for Photovoltaic Array
The design process for integrating photovoltaic (PV) maximum power point tracking (MPPT) with the Internet of Things (IoT) is discussed in detail. Required calculations, popular tracking algorithms, and converter linearity nuances are discussed surrounding a common PV system topology. A buck converter is simulated in MATLAB Simulink to confirm stable operation when perturbed by the calculated values. High resolution irradiance data was statistically analysed to provide the average irradiance slope value required to calculate a minimum duty cycle perturbation step size.
