| 摘 要： | 当光伏组件被部分遮挡时,输出的伏安特性曲线呈阶梯状,功率电压特性曲线会产生多个局部峰值点,在此情况下,现有的单体光伏电池数学模型和传统的单峰最大功率点跟踪算法都不再适用.研究和建立了适用于部分遮挡情况下串联光伏组件的数学模型,并通过Matlab软件对其进行仿真研究,分析了光伏组件在部分遮挡时Ⅰ-Ⅴ,P-Ⅴ特性曲线及输出...

| Abstract: | When PV modules are partially shaded,the output voltage-current curve is in ladder shape,and the output voltage-power curve contains several local maximum power points.The existent mathematical model of a PV cell and the traditional MPPT algorithm will not work in this instance.The mathematical model which work well under partially shaded conditions was proposed.We also research its model in Matlab.The change of I-V characteristic,P-V characteristic and output capacities of the series PV modules under parti... |
