沙戈荒新能源基地沙尘暴致灾风险预警评估综述OA

The desert,gobi,and wasteland region is a key area for the development of large-scale new energy bases in China;however,its typical arid and desert environment leads to a high frequency of sandstorm events,posing severe challenges to the safe and stable operation of wind power,photovoltaic systems,and transmission networks.This study provides a comprehensive review of recent advances in the understanding of sandstorm-induced hazard mechanisms,risk early-warning technologies,and resilience assessment methods for new energy bases.From the perspectives of photovoltaic modules,wind turbine units,and power grid equipment,we systematically analyze the primary mechanisms including wind-sand loads,particle erosion,and insulator flashover,and elucidate the evolution of multi-device,multi-process coupled hazard chains driven by sandstorms.Based on a comparative examination of sandstorm observation and forecasting methods,we further summarize the overall progress and remaining challenges in sandstorm risk early-warning systems and risk evaluation tailored to new energy bases and the resilience assessment framework covering pre-disaster protection,in-disaster stress tolerance,and post-disaster recovery stages.Finally,key directions for future research on disaster perception and early warning,risk assessment,and resilience evaluation are discussed,with the aim of providing scientific support and technical references for safe operation,risk management,and planning decisions of new energy bases.
