Maximum Power Point Tracking of PV Array under Partially Shaded Condition
摘要
Abstract
There are many local peak value of PV array under the condition of partial occlusion,in order to track the global maximum power point of the PV array, so a new method of maximum power point tracking is proposed. Firstly,partial occlusion of the output characteristics for PV array is analysied and the corresponding mathematical model is built,and secondly the perturbation method is used to search the maximum power point of the PV array which can prevent falling into the local maximum power point, finally, the performance is simulated in MATLAB 2014. The results show that the proposed method can quickly and accurately find the maximum power point,which can effectively improve the output efficiency of PV.关键词
