基于Beluco-CIWS指数的湖北省风光资源日变化互补特性分析OA

Using the 100 m wind speed and surface solar radiation data of ERA5 from 1991 to 2020,the complementary characteristics of diurnal changes in wind and solar resource elements in Hubei Province were analyzed based on the Beluco-CIWS complementarity index.The results show that:(1)the central and eastern parts of Hubei province have more strong complementarity,while the western part has poor complementarity;the higher the altitude,the weaker the complementarity,and the lower the altitude,the stronger the complementarity;the complementarity is stronger in autumn,followed by winter,and the weakest in summer;areas with higher wind speeds have strong complementarity,while areas with low wind speeds have weak complementarity;(2)the wind speeds in areas with strong complementarity show the characteristics of diurnal changes of decreasing and then increasing,with small wind speeds during the day and large wind speeds at night,and the opposite is true for the region with weak complementarity;the strength of complementarity depends on the strength of the wind speed and whether the diurnal variation characteristics are abnormal or not.
