摘要

为了保护地球,假设在撒哈拉沙漠、内盖夫沙漠、塔尔沙漠、索诺拉沙漠、大沙漠、戈壁沙漠等世界沙漠地区安装100兆瓦的超大型光伏发电(vvs - pv)系统。这些沙漠由于太阳辐射大,土地面积大,适合安装该系统。从阵列布局、支架、基础、布线等方面对光伏阵列进行了详细的尺寸标注。然后根据全寿命周期成本法估算了系统的发电成本。根据估算结果,假设光伏组件价格为1.0美元/瓦,系统寿命为30年,利率为3%,撒哈拉沙漠的发电成本为5.3美分/千瓦时,戈壁沙漠的发电成本为6.4美分/千瓦时。这些结果表明,当光伏组件价格下降到$1.0/W时,即使采用现有的光伏系统技术,在足够的辐照场地上,VLS-PV系统也是经济可行的。

A cost analysis of very large scale PV (VLS-PV) system on the world deserts
To preserve the Earth, a 100 MW very large-scale photovoltaic power generation (VLS-PV) system is estimated assuming that it is installed on the world deserts, which are Sahara, Negev, Thar, Sonora, Great Sandy and Gobi desert. These deserts are good for installing the system because of large solar irradiation and large land area. A PV array is dimensioned in detail in terms of array layout, support, foundation, wiring and so on. Then generation cost of the system is estimated based on the methodology of life-cycle cost (LCC). As a result of the estimation, the generation cost is calculated as 5.3 cent/kWh on Sahara desert, 6.4 cent/kWh on Gobi desert assuming PV module price of $1.0/W, system lifetime of 30 years and interest rate of 3%. These results suggest that VLS-PV systems are economically feasible on sufficient irradiation site even if existing PV system technologies are applied, when PV module price will decrease to a level of $1.0/W.
