基于Boost电路光伏发电系统MPPT采样周期分析
Analysis of MPPT Sampling Period of the Boost-based Photovoltaic Power Generation System
摘要
Abstract
Due to the nonlinearity of photovoltaic power generation system,it is difficult to determine a proper sam⁃pling period at each operating point in the maximum power point tracking(MPPT)mathematically. Based on the simula⁃tion and sampling of the optimal sampling period during MPPT for the Boost-based photovoltaic power generation sys⁃tem,this paper analyses the distribution pattern of the sampling period. It is indicated that since the maximum of opti⁃mal sampling period approximates to a constant value under different environmental conditions,this value is selected as the proper sampling period for the whole process of MPPT,which ensures the tracking speed and precision of MPPT.关键词
