根据全球陆地范围内的风速、风功率密度和温度等1981—2020年的历史数据,通过建立空间回归模型,预测2021—2100年不同减排情景下全球风能发电潜力和风功率密度的变化情况,结果表明,1981—2020年,全球风能发电潜力和风功率密度呈现下降... 根据全球陆地范围内的风速、风功率密度和温度等1981—2020年的历史数据,通过建立空间回归模型,预测2021—2100年不同减排情景下全球风能发电潜力和风功率密度的变化情况,结果表明,1981—2020年,全球风能发电潜力和风功率密度呈现下降的趋势,而全球温度呈现上升的趋势,两者存在一定程度的相关性。简单线性回归模型结果显示,各大洲的年均发电潜力与全球11个地区的平均温度有较好的相关性,且大部分区域都呈现负相关关系。未来不同共享社会经济路径(SSPs)情景下,全球总的年风能发电潜力会有较明显的差异。在温度上升最快的SSP5-8.5情景下,21世纪末的发电潜力比2020年代下降3.3%;在减排力度最高的情景SSP1-1.9下,全球年发电潜力会随着温度的下降而回升,有望在21世纪末回到21世纪初的发电潜力。与最优情景SSP1-1.9相比,其他SSPs情景下,大部分(61%)网格化的风功率密度表现出下降趋势,且温度上升越快,风功率密度值下降越多,未来可实现风能发电的潜力越小。 展开更多

Climate change threatens the sustainable development and survival of the small Caribbean island nations. The continual rise in the demand and cost of the earth's finite hydrocarbon energy reservoir drives these countries to examine the integration of renewable energy to reduce green house gas emissions whilst meeting their electrical energy demands. One possible renewable energy source is wind. Trinidad and Tobago, through its renewable energy policy, is seeking to reliably and economically integrate wind power with its conventional power generation sources. This paper assesses the adequacy of wind power generation at potential sites through the use of auto-regressive modeling and the use of Monte Carlo Simulation to evaluate the well-being indices for the combination of wind and conventional power generation. Two sites in the twin island Republic of Trinidad and Tobago were identified as case studies for the proposed methodology. Analysis of the results indicated that the methodology should be applied to sites with conditions encouraging economic feasibility of wind power generation. 展开更多
