碩士 / 國立嘉義大學 / 景觀學系研究所 / 106 / The use of renewable energy is rapidly increasing to reduce the impact of global warming. Considering that there is an excellent offshore wind potential in Taiwan Strait, the wind energy resources evaluation becomes important for promoting offshore wind energy. The evaluation of wind energy resources is based on a large amount of measured data. In view of the difficulties in the observation of marine weather and the lack of reliable observation data, this study used reanalysis data (Modern-Era Retrospective analysis for Research and Applications, MERRA), Central Weather Bureau weather station (CWB), Floating Lidar, Taipower Mast, measure correlate predict method (MCP) and Windsim wind energy assessment software. Through the cases of Miaoli and Changhua, we aimed to find out the selection principle of weather station and mesoscale data points. In addition to wind source, annual energy production (AEP), wake loss and operating cost were also analyzed.
The result of this study indicated that MCP can improve the accuracy of CWB. However, if the original CWB has high correlation, MCP will reduce CWB correlation. CWB station is recommended to be near the simulated position, offshore, high altitude station; MERRA point selection order is recommended in the offshore waters, close to the simulated position. The more complex the terrain is, the more susceptible the simulated result will be.
The simulation result of the Taipower-Changhua-South Wind Farm simulation indicatd that Fangyuan Station figured out averaged wind speed of 12.27 m/s, which is higher than floating lidar with 7.67 m/s and Taipower Mast with 7.63 m/s. It’s the same results from the power density. In addition, the annual energy production of the Fangyuan Station was 403.6GW, and the floating lidar was 258.5GW, Taipower Mast was 251.8GW. The energy cost per kWh for Fangyuan Station was 26.9687 US dollars, floating lidar 42.1124 US dollars and the Taipower Mast 43.2236 US dollars. The wind shear of the land environment is much higher than offshore, leading to high simulated wind resource.
