碩士 / 國立臺灣大學 / 生物環境系統工程學研究所 / 100 / Ever since Industrial Revolution, fossil fuel has been overly used and greenhouse gas produced subsequently led to global warming and climate change. Also, due to recent global oil crisis, developing alternative renewable energy becomes important among nations. Surrounded by water, Taiwan has plenty of wind energy andrecently has a growth spurt on the development of wind resources. However, there are two limitations for the development of wind industry in Taiwan: the confined yet densely populated land and the growing of greenhouse effect. Taiwan’s west coast has been considered the best location for wind energy development, where Bureau of energy, Ministry of Economic Affairs has been endeavored to offshore wind output.
This study uses GCMs published by IPCC to see how climate change might affect wind energy and energy output on offshore on the west coast. Multi-Variable Regression and Weibull wind speed probability distribution were firstly applied to estimate wind energy and to establish a spatial wind atlas in 5km×5km resolution, so as to avoid potential mistake caused by stretched grid within Global Circulation Model. Secondly the nominal performance curve of WECS at rated power was implemented to estimate the energy output for 90 years from now. As a result, wind energy on the offshore of Hsinchu, Miaoli and Taichung appears to be higher. Hsinchu has the highest energy output, and the energy output will increase evidently by the distance offshore in 30km.The result also suggests that WECS at 3.0MW is better implemented in this area. To conclude, wind output in Taiwan might be shortened in the near future due to a weakened northeast monsoon caused by climate change.
