摘要
太阳能资源的高效开发和利用对人类减少化石燃料的消费及温室气体的排放具有重要意义,为进一步加强东北地区尤其是哈尔滨市区域太阳能资源的高效开发,精细化分布评估和长时预测必不可少.选取国际耦合模式比较计划第六阶段(CMIP6)的数据集,利用分位数映射法,对研究区域未来 30 年太阳辐射数据进行降尺度处理,从而获得高分辨率太阳辐射数据;根据预测数据分析太阳辐射强度时空分布规律,评估太阳能资源丰富度及稳定性.结果表明:未来 30 年太阳总辐射呈缓慢的下降趋势,2020-2029 年太阳能资源最丰富;总辐射量和日照时数呈现西多东少的分布,尤其是西南区域太阳能资源最富裕,整个区域都达到太阳能资源很丰富的水平,太阳能资源稳定性高,具有很大的开发潜力.
Abstract
The efficient development and utilization of solar energy are of great significance for reducing the consumption of fossil fuels and greenhouse gas emissions.In order to further develop the solar energy in Northeast of China,especially in the area of Harbin,it is necessary to make refined distribution assessment and long term prediction.In the present work,the da-tabase of the CMIP6 was selected and downloaded,and the quantile mapping method was used to downscale and obtain high-resolution solar radiation data in the focusing area in the next 30 years.Based on the prediction data,the temporal and spa-tial distributions of global horizontal irradiance were studied,and the stability of solar energy resources was evaluated.The results show that the total solar radiation will decline slowly in the next 30 years,and the solar energy resources will be the most abundant in 2020-2029.The GHI and sunshine hours appear more in the western than in the eastern part,especially in the southwest,where the solar energy resources are the richest.The entire region is rich in solar energy resources and the so-lar energy resources are stable and have great development potential.
