Assessment of Wind Resources at the Gobi Desert Wind Farm Clusters with Consideration of Atmospheric Stability
The Gobi desert wind farm cluster is characterized by large diurnal temperature differences,susceptibility to atmospheric stability,and a lack of representative wind measurement data.It is urgent to assess the wind resource characteristics of the Gobi desert wind farm.This study focused on the wind farm in Inner Mongolia's Alxa League,which was under construction then.Weather research and forecasting models were utilized for numerical simulation.Wind measurement data was employed to validate the model's accuracy,emphasizing the spatial and temporal distribution characteristics of atmospheric stability and its impact on wind speed.The research indicates that wind speed and wind power density in the region are higher from November to May of the following year,particularly affected by the northwest monsoon,with a sharp decrease in wind power accompanying the passage of cold waves.The proportion of neutral atmospheric conditions peaks in winter,and wind speeds are optimal under neutral conditions.Compared to flat terrain,mountainous regions exhibit a significant decrease in the proportion of strongly stable and strongly unstable atmospheric states,with a corresponding increase in the proportion of neutral atmospheric stability.Specifically,the proportion of neutral atmospheric conditions in mountainous regions during winter can reach 48.4%,providing theoretical and technical support for the micro-site selection of the Gobi desert wind farm cluster.
