Evaluation of wind energy resources and wind power generation based on SAR-retrieved wind in the eastern sea area of Yancheng, Jiangsu, China

摘要

Evaluation of wind energy resources and wind power generation can provide decision basis for wind energy construction. Based on the study area in the eastern sea area of Yancheng, 8 scenes of ERS-2 SAR images in 2007 are collected to retrieve wind field and the retrieval results are verified by QuikSCAT wind data. Then, average wind power density is figured out to evaluate wind energy resources and unit capacity of wind power generator is calculated to evaluate wind power generation. The results show that: (1) it is feasible and accurate to retrieve wind speed based on CMOD5 model; (2) regional variations of wind energy resources and wind energy storage in different seasons should be taken into account; (3) average wind power density is from 1.22 to 929.51W/m2, and wind energy resources are abundant in three areas, the unit capacity of which could reach to 442.84, 1181.02 and 1491.31 kW.
