Abstract
To study the impact of partial occlusion on the generating capacity, this paper builds a simulation model based on MATLAB with PV cells as the basic unit, and takes the actual PV module as the object of study. This PV cell model can simulate the forward and reverse characteristics of PV cell, and the PV array model can simulate the output characteristic of PV array. The current reduction of occlusion cell is the ultimate reason of the power curve multi-peak. The paper studies the law of output characteristic of PV string under different partial occlusion, and analyzes the output characteristics of the different array configurations and the difference of distributed MPPT and centralized MPPT. So the simulation provides some basis for optimize PV power generation system and MPPT.关键词
