不规则场地中跟踪式光伏阵列的优化排布方法
|
摘要
针对边界不规则的光伏电站建设场地,以提高土地利用率为目标,在相邻光伏设备阴影互不遮挡的前提下,研究了影响跟踪式光伏阵列工作效率、装机容量的主要因素,引入二维图形排样理论设计了一种不规则场地中跟踪式光伏阵列的优化排布方法,并仿真验证了该方法的有效性,实验结果表明优化排布可提高装机容量5.94%～11.59%,能更有效利用土地资源。
Focusing on the construction site of photovoltaic power station with irregular boundary, the main factors influencing the working efficiency and installed capacity of tracking photovoltaic array were researched under the premise of shadow of adjacent photovoltaic equipment for improving the utilization ratio of the land. By introducing the theory of two-dimensional pattern packing, a method of optimal arrangement of tracking photovoltaic array in irregular site was designed, and the effectiveness of the method was verified by simulation. The experimental results show that the new method can increase the installed capacity of 5.94%-11.59% and make effective use of land resources.
