摘要:

青藏高原风光资源丰富,是中国重要的清洁能源战略储备基地。然而,气候变暖正显著改变高原风速和太阳辐射等关键气象要素,加剧了风光资源开发的不确定性。加之资源禀赋与人口分布存在空间错配,系统评估未来气候风险格局尤为必要。本研究基于NEX-GDDP-CMIP6多模式集合数据,在3种共享社会经济路径(Shared Socioeconomic Pathways,SSPs)下,模拟了青藏高原风能发电潜力(wind power potential,Pwind)与光伏发电潜力(solar power potential,Psolar)的未来长期平均变化,并量化了年内波动性、极端事件及日际急升骤降的多时间尺度变化特征。结果表明:(1)青藏高原风光发电潜力对温室气体排放高度敏感,低排放情景下Pwind下降4.2%、Psolar小幅上升,高排放情景下两者降幅分别达10.9%和2.8%,风电脆弱性更大。(2)排放越高,年内波动性与日际急升骤降频率越强,高排放情景下风电年内波动性增幅达8.6%,急升骤降影响月份从不足半年扩展至全年多数月份;极端事件呈现明显的季节分异,风电极端高发电事件在所有情景下均未发生。(3)风光联合开发可有效缓释单一能源的气候风险。高排放情景下风光耦合使高及极高风险区占比由单一能源的75.1%和69.5%降至4.7%。

Abstract:

The Qinghai-Xizang Plateau is endowed with abundant wind and solar resources, serving as a critical strategic reserve base for clean energy in China. However, ongoing climate warming has significantly altered key meteorological factors over the plateau, including wind speed and solar radiation, thereby increasing the uncertainty of wind and solar energy exploitation. Furthermore, the prominent spatial mismatch between resource endowment and population distribution highlights the necessity of systematically evaluating future climatic risk patterns. Based on the multimodel ensemble dataset of NEX-GDDP-CMIP6, this study simulates the long-term future changes of wind power potential (Pwind) and solar power potential (Psolar) across the Qinghai-Xizang Plateau under three Shared Socioeconomic Pathways (SSPs). Multiple temporal characteristics are quantitatively assessed, including annual mean trends, intra-annual variability, extreme events, and day-to-day abrupt fluctuations in power potential. The results indicate that: (1) The wind and solar power generation potentials on the Qinghai-Xizang Plateau are highly sensitive to greenhouse gas emissions. Under the low-emission scenario, Pwind decreases by 4.2% while Psolar increases slightly; under the high-emission scenario, the declines reach 10.9% and 2.8%, respectively, showing greater vulnerability of wind power. (2) Higher emission scenarios lead to stronger intra-annual variability and more frequent day-to-day sharp rise and drop events. Under the high-emission scenario, the intra-annual variability of wind power increases by 8.6%, and the affected months of sharp rise and drop events expand from less than half a year to most months of the year. Extreme events exhibit pronounced seasonal differentiation, and extremely high wind power generation events do not occur under any scenario. (3) Joint wind-solar development can effectively mitigate the climate risks of single energy sources. Under the high-emission scenario, wind-solar coupling reduces the proportion of high and extremely high-risk areas from 75.1% and 69.5% for single energy sources to 4.7%.
