局部遮挡下光伏电池的数学建模与仿真研究
Mathematical modeling and simulation study of photovoltaic cells under partially shading
摘要
Abstract
Under partially shading condition,I-V output characteristics of photovoltaic(PV) array is in stair stepping and P-V output has multiple local peaks.Based on engineering mathematic model of photovoltaic cell,the output characteristics of series array,parallel array and series-parallel photovoltaic array were studied.Then the location of the maximum power point and maximum power point mechanisms were theoretically explored and the corresponding mathematical model was established.The correctness of theory was verified by computer simulation.It's concluded that the output characteristics of PV array are commonly determined by illumination,shading mode and distribution of PV arrays.关键词
