准确评估煤矿塌陷区光伏发电潜力，对于资源型城市转型、实现碳中和目标具有重要意义。本文提出了煤矿塌陷区光伏发电潜力评估方法。干涉合成孔径雷达充分考虑了环境因素和地面变形。此外，还预测了沉陷地区光伏发电的平准化成本和效益。选择山西省阳泉市作为研究案例。结果表明，阳泉沉陷区在（−40，−10）、（−50，−10）和（−60，−10）mm/年3个变形率范围下光伏发电的最佳面积分别为32.13、37.89和41.22 km2。选取的最佳光伏建设区域与现有光伏设施吻合较好，说明了该方法的有效性。能源平准成本预计为0.3934元/千瓦时。年发电量可满足阳泉市约33%的电力需求。该工作将指导煤矿塌陷区光伏发电设施建设，促进矿产资源型城市转型升级。
Accurately assessing the photovoltaic (PV) power generation potential in coal mining subsiding regions is of great significance for the transformation of a resource-based city and the goal of carbon neutrality. In this paper, we proposed an assessment method for the PV power potential in coal mining subsidence areas. Both the environmental factors and ground deformation by interferometric synthetic aperture radar were fully considered. Furthermore, the levelized cost of PV electricity in subsidence areas and the benefits were predicted. Yangquan City, Shanxi province was selected as a study case. Results show that the optimal areas for PV power generation under the three-deformation rate ranges of (−40, −10), (−50, −10), and (−60, −10) mm/year in the Yangquan subsidence area are 32.13, 37.89 and 41.22 km2, respectively. The selected optimal PV construction regions agree well with the exiting PV facilities, indicating the effectiveness of the proposed method. The levelized cost of energy is estimated at 0.3934 RMB/kWh. The annual power generation can meet about 33 % of the electricity demand of Yangquan City. This work would guide the construction of PV power generation facilities in the coal mining subsidence areas for the transformation and upgrading of the mineral resource-based cities.
