A numerical model system is built which is suitable for regional wind energy resource assessment and is composed by mesoscale meteorological model MM5, microscale module Calmet and calculation module of wind energy resource parameter. By using the model system, wind energy resource of littoral area in Jiangsu Province and Jiuquan area in Gansu Province are numerically simulated hour by hour with a fine resolution of 1 km×1 km. Littoral area in Jiangsu Province stands for Chinese littoral enrichment area of wind energy resource, and Jiuquan area in Gansu Province stands for north enrichment area in the condition of complex terrain. The model system is evaluated by comparisons between observational datum of wind mast in simulation area and simulation datum. The comparisons indicate that the wind energy resource distribution of the two areas is well simulated by the model system, and the simulation results of the annual average wind speed, the direction frequency of wind and wind power agree well with the observational datum. The comparisons between simulation results and observations of Jiuquan area in Gansu Province are better than that of littoral area in Jiangsu Province. Hence, the wind energy resource assessment under different terrain conditions is well numerically simulated by the model system. And the following results are indicated by the analysis of annual average wind speed and wind power, annual effective hour, and annual energy production: the wind energy resource of off-shore in Jiangsu Province is richer than that of on-shore, and it is richer from north to south; the wind energy resource of the central basin area in Jiuquan area is very rich as where is in the area of south-north facing high mountains.
