中文摘要：
为了进一步减少光伏组件工程用单指数数学模型中,光伏组件随环境温度和太阳辐射照度变化时输出的电流、电压和功率的估算误差,设定±3%误差控制目标,利用短路电流、开路电压、峰值功率电流和峰值功率电压四个参数,将两种常用的技术方案与四组实际光伏组件的实测输出值进行比较,得到其中一个方案的参考系数需要进一步修正的结果。将光伏组件电流输出方程对环境温度和太阳辐射照度的微分与实测值进行拟合,得到新的参考系数值。最后,基于MATLAB/SIMULINK模拟仿真其中一组光伏组件的电压、电流和功率的输出特性,为工程上不同光伏组件的数学模型参数估算提供了新的方法。
英文摘要：
A new design method was proposed for further reducing parameters estimation on the photovoltaic module based on single exponential mathematical model. Error control target was settled with use of short circuit current,open circuit voltage, current and voltage of peak power. The two common technical approaches were compared to obtain a result of which one reference coefficient needed to rectify further according to four photovoltaic experiment tests. A new reference value had been gotten with the differential equation of temperature and solar irradiance.Finally, the voltage and current and power output characteristics of a group of photovoltaic modules were modeled based on MATLAB/SIMULINK.
