摘要
随着光伏发电日益广泛的应用,对光伏发电系统的研究得到了越来越多的重视,其中光伏电池输出特性的模拟仿真是构成光伏发电系统的基础部分。对现有两种普遍应用的光伏仿真模型输出特性进行比较,分析其输出特性的区别,以便对后续光伏发电系统的仿真提供基础依据。利用Matlab/Simulink建立光伏发电系统模型,通过该模型分别得到光伏物理仿真模型和数学仿真模型的输出特性,并通过比较分析其输出特性的区别。通过实验可以看出,两种模型在P/U输出特性的速率方面仍有所区别,物理仿真模型输出特性与实际输出特性更为接近,得出的结果可以对后续光伏发电系统仿真及其MPPT研究给与参考。
With the increasingly widespread use of photovohaic （PV） power generation, the research of photovoltaic power generation system has been attracted more and more attention, and the simulation of output characteristics of photovohaic cell is the basic parts of photovoltaic power generation system. Two widely used simulation models for PV output characteristics are compared, and the differences between the output characteristics of these two models are analyzed. A model of photovohaic power generation system is established with Matlab/Simulink. The output characteristics of the photovoltaic physics simulation model and mathematical simulation model are obtained through the established model, and the differences between their output characteristics are compared and analyzed. Through this experiment, there still have some differences between the rates of P/ U output characteristics in these two models, and the output characteristics of the physical simulation model is more close to the actual output characteristics, which can give a reference for the subsequent simulation and MPPT research of photovoltaic power generation system.
