湖南光伏发电气候适宜性研究

Study on Climate Suitability of Photovoltaic Power Generation in Hunan Province

利用湖南省97个国家地面气象站和3个辐射站1985—2015年的日照时数、日照百分率、浮尘日数以及太阳辐射观测资料,基于中国气象局最新发布的太阳能资源评估方法,分析了湖南省各地区的辐射总量、辐射稳定度、光伏发电年保证率、年浮尘日数。综合上述四个指标,进行了湖南省光伏发电气候适宜性区划;依据1985—1995年、1996—2005年及2006—2015年三个时间段的气候观测数据,分析了气候变化对湖南省光伏发电气候适宜性的影响。结果表明:在湖南省境内,不适宜区占全省总面积的8.07%,次适宜区占14.95%,较适宜区占29.83%,适宜区占47.15%,洞庭湖区和湘东南具有最适宜开展光伏发电的气候条件。

Based on the solar energy resources assessment method issued by China Meteorological Administration,the total radiation amount,radiation stability,annual guarantee rate of photovoltaic power generation and annual floating dust days of 97 national surface meteorological stations and 3 radiation stations in Hunan Province from 1985 to 2015 were analyzed.Based on the climate observation data of 1985-1995,1996-2005 and 2006-2015,the impact of climate change on the climate suitability of photovoltaic power generation in Hunan Province is analyzed.The results show that:in Hunan Province,the unsuitable areas account for 8.07% of the total area of the province,the sub suitable areas account for 14.95%,the more suitable areas account for 29.83%,and the suitable areas account for 47.15%.Dongting Lake region and Southeast Hunan Province have the most suitable climate conditions for photovoltaic power generation.
