Wind Energy Estimation and Siting in Complex Terrain

Abstract

In this review, we examine the currently available algorithms for predicting the wind field in rough terrain for potential wind power estimation. Numerical codes are conveniently divided into kinematic mass-consistent flow field ones that do not explicitly utilize the momentum equation, and dynamic ones that solve the full set of environmental fluid mechanics equations appropriate to mesoscale regions. Short descriptions for the most important codes are given and their advantages and disadvantages for wind energy prospecting are discussed along with some aspects of the appropriate methodology for deriving climatic averages appropriate for rough terrain. Finally, an example of the results of one of these models applied to the island of Andros, Greece which is known for its windy climate is presented.
