在这项研究中，我们采用了地理信息系统（GIS）为基础的方法，以确定适合在蒙古国的大型太阳能光伏（PV）发电厂安装的网站。因此，使用30 × 30 m的单元，并根据7个标准收集数据，包括年全球水平辐射，年平均温度，海拔，坡度，坡度方向（方面），距离主要道路和主要电力线，每个单元。这七个标准的GIS图层，然后转换成额定值层使用四个等级。应用于七个标准的权重是由十位太阳能领域专家使用层次分析法确定的。通过将七个等级值层与权重相结合，开发了一个站点适合性地图，使用良好，公平，低，差的适合性等级。结果表明，优良、一般、低、差的立地面积分别占总面积的3.27%、53.06%、42.59%和1.08%。好的地点主要位于蒙古的南部和中部地区。由于目前南部和中部地区的电力需求分别较低和较高，我们得出结论，蒙古国中部地区应优先安装光伏电站。
In this study, we employed a geographic information system (GIS)-based approach to identify sites suitable for large-scale solar photovoltaic (PV) power plant installations in Mongolia. Accordingly, cells of 30 × 30 m were used, and data based on seven criteria, including annual global horizontal radiation, annual average temperature, elevation, slope, slope direction (aspect), and distances from main roads and major power lines, were collected for each cell. GIS layers for these seven criteria were then converted into rated value layers using four grades. The weightings applied to the seven criteria were determined, using an analytical hierarchy process, by ten solar field experts. By combining the seven rating value layers with the weightings, a site suitability map was developed, using good, fair, low, and poor suitability grades. The results showed that sites graded as good, fair, low, and poor accounted for 3.27%, 53.06%, 42.59%, and 1.08% of the total surface area, respectively. Good sites were predominantly located in the southern and central regions of Mongolia. As the current demand for electric power in southern and central regions is low and high, respectively, we concluded that the central region of Mongolia should be prioritized for installing PV power plants.
