光伏电池模型综述

Review in photovoltaic cell model

在复杂工况影响下,通过物理实验方法观测光伏电池输出特性比较困难。光伏电池作为光伏发电系统的核心部件,对其建模与仿真,研究不同工况条件下光伏系统的输出特性,是光伏发电系统研究和设计的重要依据,也是研究最大功率追踪算法和故障诊断方法的首选途径。国内外学者对光伏电池模型做了大量研究,给出很多光伏模型,可将已有建模方法分为三类。即电路模型、工程模型和拟合模型,并根据对模型精确度要求和应用场所选择合适建模方法。

It was difficult to observe the output characteristics of photovoltaic cells by physical experiments under complex operating states.PV module was the core components of the pv power generation system,it was very important to build model and simulation for research and design of such system.PV simulating model was also the preferred route to study the maximum power point tracking algorithm and fault diagnosis methods.Domestic and foreign scholars had done a lot of researches on the PV cell models,the PV cell modeling methods could be divided into three categories,namely circuit model,engineering model and fitting model and appropriate modeling method should be selected based on the model＇s accuracy requirements and application environment.
