摘要
以不同类型的光伏支架作为研究对象,采用PVsyst软件,根据不同类型光伏支架的特点,通过数值模拟方法建立不同纬度、不同光照资源条件下的光伏方阵模型,对其采用不同类型光伏支架时的发电量及平准化度电成本(LCOE)差异进行了分析研究,并以LCOE作为评价指标指导光伏支架的选型。研究结果表明:在低纬度地区,光伏方阵采用固定式光伏支架时的LCOE最低;在中纬度地区,与采用固定式光伏支架时相比,光伏方阵采用平面单轴光伏跟踪支架时发电量明显提升,LCOE最低;而在高纬度地区,与采用固定式光伏支架时相比,光伏方阵采用平面斜单轴光伏跟踪支架时发电量明显提升,LCOE最低。
Taking different types of PV brackets as the research object,using PVsyst software,according to the characteristics of different types of PV brackets,through numerical simulation method,the model of PV array under different latitudes and different lighting resources is established.The difference of power generation capacity and LCOE of PV array with different types of PV brackets is analyzed and studied,and the LCOE is taken as the evaluation index to guide the selection of PV brackets.The results show that in low latitudes,the LCOE of PV array with fixed PV brackets is the lowest.In the middle latitudes,comparing to fixed PV brackets,when the PV array adopts the horizontal single axis PV tracking brackets,the increase of power generation capacity is significantly,and the LCOE is the lowest.In the high latitudes,comparing to fixed PV brackets,when the PV array adopts the horizontal inclined single axis PV tracking brackets,the increase of power generation capacity is significantly,and the LCOE is the lowest.
