Wind Resource Assessment over Large Area Using Wind Energy Simulation Toolkit (WEST)
WEST was used to create the Canadian and Chinese wind atlas using mosaic approach. The preliminary validation showed that WEST has simulated well the mean wind speed over the terrain lower than 1 km Above Sea Level (ASL). However, the model error is large over highlands such as in Qingzang Plateau and Tianshan Mountains of China. This may result from the classification scheme, in which geostropic wind at sea level was used. Interpolating meteorological variables from highlands (e. g. 3km ASL) to sea level can generate large errors. A terrain following classification scheme is under development in order to minimize the simulation error over highlands. Inaccurate land-use data (or vegetation cover) was also identified as another source of simulation error. Sensibility study showed that an accurate specification of vegetation cover helped to improve the model simulations. It is important to use local high resolution surface database in WEST simulations.
