Assessment of wind speed and power potential in Qinghai Province during the "double carbon" period
The utilization of wind energy resources is the top priority to achieve the "carbon peaking and carbon neutrality goals". Based on daily wind speed observation and simulations from 5 CMIP6 models with 7 Shared Socioeconomic Pathways,this study constructs a database with 1 km horizontal resolution and analyses the spa-tiotemporal changes of the wind power in Qinghai Province during 1961—2022,"carbon peak" period of 2026—2035 and "carbon neutral" period of 2056—2065. The results show:(1) From 1961 to 2022,the average annu-al 10 m wind speed in Qinghai Province is 3.06 m·s-1,the 100 m wind power densities is 125.14 W·m-2,and the number of wind energy available days is 167. The wind power decreases gradually from the west to the east. The wind energy resources in Tsaidam Basin and Tanggula Mountains reach the suitable development standard,and the maximum value is in the west of Burhan Budai Mountains;(2) Wind power in Qinghai Province exhib-its a decreasing trend. The reduction speed of 10 m wind speed is 2.08％·a-1,the 100 m wind power density is 1.40％·a-1 and the available days of wind energy is 0.88％·a-1;(3) Compared with the historical period,the 10 m wind speed at is 2.52 m·s-1 (2.39～2.63 m·s-1) with a decrease of 3.53％ (2.34％～5.24％),the wind power density is 50.28 W·m-2 (46.17～64.08 W·m-2) with a decrease of 10.20％ (6.69％～14.91％),and the wind en-ergy available days is 114 days (105～124 days) with a decrease of 7.58％ (2.44％～11.05％) from 2026 to 2035. From 2056 to 2065,the wind speed at 10 m is 2.49 m·s-1 (2.31～2.59 m·s-1) with a decrease of 5.71％ (5.21％～6.53％),the wind power density is 47.75 W·m-2 (38.89～54.79 W·m-2) with a decrease of 15.79％ (14.72％～18.32％),and the wind energy available days is 111 days (99～120 days) with a decrease of 10.73％ (8.39％～13.55％);(4) From 2026 to 2035 and 2056 to 2065,the 10 m wind speed at low emission scenarios (SSP1-1.9,SSP1-2.6 and SSP4-3.4) is 1.75％ and 5.16％ higher than high emission scenarios (SSP3-7.0,SSP5-8.5),the 100 m wind power density is 5.23％ and 14.28％ higher,and the wind energy available days is 3.32％ and 9.71％ more. In general,the wind power in western part of Qinghai Province,especially Tsaidam Basin and Tanggula Mountains,is most abundant with relatively minor reduction,which has broad prospects for development and utilization.
