摘要
针对太阳能电池模型工程求解困难的问题,基于太阳能电池单二极管等效电路,分别建立最大功率点电压与日照强度、太阳能电池温度以及最大功率点与最大功率点电压之间的近似线性关系,并通过最小二乘线性拟合求解线性系数以达到最佳拟合。基于多晶硅、单晶硅和非晶硅太阳能电池工程参数求解仿真实验验证了该文求解方法的正确性,随机环境下的相对误差能达到6.0%以内,可以满足大多数工程精度要求。最后,最大功率点跟踪实验也表明了求解方法在实际工程中应用的可行性,并能提高突变环境下的跟踪精度。
Aiming at the engineering solution problem of solar cell model,the approximately linear relationship between maximum power point( MPP) voltage and solar irradiation,solar cell temperature,MPP and MPP voltage is established respectively based on the singlediode equivalent circuit of solar cell,and the linear coefficient is solved by least squares linear fitting to achieve the best fitting. Based on the engineering parameters solution of polycrystalline,monocrystalline,and amorphous silicon solar cell,the simulation results show that the algorithm is correct,and the relative errors in the random environment are within 6. 0%,which can meet the requirements of most engineering precision. Finally,the MPP tracking experiments also show the feasibility of the algorithm in practical engineering,and it can improve the tracking accuracy for the sudden change of environment.
