通用斜面总辐照量公式被广泛应用于光伏发电预测物理模型中.对于多安装角度的建筑集成光伏(Building Integrated Photovoltaic,BIPV)系统,通用斜面总辐照量公式由于没有考虑倾角因素的影响,存在预测精度低、计算复杂等问题.通过对典型BIPV系统不同倾角对斜面总辐照量影响的分析,提出一种基于多项式拟合的BIPV系统斜面总辐照量计算方法,并利用贝叶斯信息准则(Bayesian Information Criterion,BIC)确定最优多项式阶次.该方法相对于通用计算公式具有原理简单、计算便捷、准确度高的优势,并且对不同倾角具有较强的适应性.将该方法应用于BIPV系统发电量预测试验,验证了该方法相对于通用斜面总辐照量公式的优越性.
The general formula of total irradiance of inclined plane is widely used in the physical model of photovoltaic power generation prediction.For building integrated photovoltaic(BIPV)systems with multiple installation angles,the general formula of total radiation of inclined plane does not take into account the influence of inclination angle,which has problems such as low prediction accuracy and complex calculation.Based on the analysis of the influence of different inclinations of typical BIPV systems on the total irradiance of inclined planes,a method for calculating the total irradiance of inclined planes of BIPV systems based on polynomial fitting is proposed.The Bayesian Information Criterion(BIC)is used to determine the optimal polynomial order.Compared with the general calculation formula,this method has the advantages of simple principle,convenient calculation,high accuracy,and strong adaptability to different inclinations.The method is applied to the power generation prediction test of BIPV system,and the superiority of the method over the general slope total radiation formula is verified.
