摘要
基于2010~2011年北京地区太阳辐射及气象资料,提出一种基于修正后清晰度指数和总云量交叉划分的天气类型识别方法,比较3种经典的各向同性、异性斜面辐射模型,开展不同跟踪方式下光伏发电系统能量收益差异对比分析及动静态评估。结果表明:该文所提出的新型天气类型划分方法能显著区分总辐射中不同成分的差别;天气情况、季节变化对北京地区不同跟踪系统下光伏组件表面辐射接收情况有显著影响;不同天气类型及不同季节下,跟踪系统的适用度不同。
Based on the radiation and meteorological data in Beijing from 2010 to 2011,a weather type identification method based on the cross division of the revised definition index and the total cloud volume is proposed.By analyzing three classical isotropic and heterosexual slope radiation models,the energy acquisition of the photovoltaic generation system under different tracking methods is proposed.The results show that the proposed weather classification can distinguish the difference of the different components in the total radiation accurately.The weather and seasonal changes have significant influence on the surface radiation reception of the photovoltaic components under different tracking systems in Beijing,and the applicability of the tracking system is different under different weather types and different seasons.
