2 FOREWORD This summer school is a collaboration of ForWind Center for Wind Energy Research at the University of Oldenburg in Germany with National Cheng Kung University (NCKU) and National Chia Yi University (NCYU) in Taiwan. The German lecturers with support of the instructors in Taiwan will present the undergraduate and graduate students in Taiwan about: Wind energy and the global need for renewable energy The basic physical and technical principles of wind energy conversion into electric energy Wind data analysis Typhoon risks for wind turbines and how to deal with them New wind measurement techniques (floating Lidar, sphere anemometer) Beyond that, all students have the opportunity to spend a lot of time with all lecturers from Germany and make close contacts with them. This includes discussions on options for continuing studies in Germany. Students, who officially register in NCKU for this summer school, receive a certificate of attendance and 3 credit unit from NCKU. National Cheng Kung University is proud and honored to host the summer school. The theme of the summer school is Wind Energy Technology for Global Challenge. The emerging Global Challenge issue is a vital step to promote the wind energy in Taiwan, the Pacific region, and the world. This summer school intends to foster the spirit of international collaboration and acts as an international forum for young students, researchers and industrial partners interested in applying state of the art wind energy technology to solve one of Global Challenge issues. The forum shall bring together experts from many disciplines to identify areas of synergy and to spur technological advances in the near future On behalf of the Summer School Program Organizers, we would like to warmly welcome your participation, and sharing ideas. We especially appreciate the Germany Academic Exchange Service (DAAD) for supporting this summer school. We also thank for the lecturers of this summer school, National Energy Program Phase II (NEP II), and Research Center of Energy Technology and Strategy (RCETS) of National Cheng Kung University. Logistic supports from NCKU s colleagues, staffs and students are sincerely appreciated. Tzong Shyng Leu, Program Organizer of Summer School & Technical Program
