摘　　要：为研究动态环境变量与太阳电池输出特性的关系,在分析太阳电池工程数学模型的基础上,根据MPPT算法和电池外特性,提出2种新的电池模型表征思路。建立动态环境变量与开路电压U（oc）、短路电流I（sc）、最大功率点电压Um、最大功率点电流Im和最大功率点功率Pm这5个太阳电池输出特性参数之间的联系,并在Matlab/Simulink平台上搭建对应的仿真模型。同时,通过温度变化对太阳电池输出特性影响的试验,说明模型的有效性。试验结果表明基于MPPT算法的太阳电池模型相较于基于外特性的仿真模型计算结果误差率更低,但计算过程更复杂。In order to study the relationship between the dynamic environment variable and the output characteristics ofsolar cell,two new battery models have been proposed based on the research on the mathematical model of the solar cell.According to the MPPT algorithm and the external characteristic,the connection between the dynamic environmentvariable and the parameters on the output characteristics of solar cell has been established,including open circuitvoltage,short circuit current,voltage,current and power of the maximum power point.Meanwhile,the simulationmodels in the Matlab/Simulink platform have been put up and the test on the effect of the temperature to the outputcharacteristics of the solar cell has been developed,which shows the validity of the model.And the test results show thatthe calculation error rate of the solar cell model based on MPPT algorithm is less than that of the solar cell model basedon external characteristic,while the calculation process will be more complicated.
