固定式光伏发电组件最佳倾角的聚类分析方法

在集中式大型光伏系统工程设计过程中，固定式光伏组件的倾角直接影响着整体光伏组件的IV输出特性，从而直接关系到光伏发电系统的收益。即固定式光伏组件的安装倾角不同，整个光伏系统所接收到的有效太阳辐射量不同，其发电量在一年范围内的差距较大，为此，为有效应对光伏组件安装倾角受限于经纬度、地域环境等多影响因素，追求大型集中式光伏发电系统的经济性，提出了一种考虑区域经纬信息的光伏发电组件最佳倾角聚类分析方法，并在华北地区某174MW大型光伏电站设计过程中应用，其计算结果与PVsyst软件所计算的结果对比分析，验证了所提算法的有效性。

An optimal tilt angle method of the fixed PV generation based on clustering analysis

In the process of engineering design for large scale centralized PV generation, the optimum tilt angle of the fixed PV module directly affects the input and output of the whole PV systems, which directly relates to the revenue of the PV generations. The installation angel of the fixed PV components in PV generations is different, and the received effective solar radiation is different, and the power of PV generations is a big gap in a year. To this end, considering the many factors of the latitude and longitude, geographical environment, and the economy of the large scale centralized PV generations, the best angle method of PV generations is proposed to balance the regional transit information and the best cost-benefit, based on data clustering analysis. The effectiveness of this algorithm is verified by the application of a large area in the north of 174M PV power station, and comparing the calculation result with the PVsyst software.
