ABSTRACT
As the increasing number of wind energy is integrated into the national power grid, analyses of wind energy are becoming increasingly more crucial. The interaction between the topography and the northeast (NE) monsoon brings abundant wind resources to the Taiwan Strait in autumn and winter. The offshore area has stronger and more stable wind resources, so deployment of offshore wind power is also actively being carried out. However, development of offshore wind power systems requires stricter evaluation and decision-making. Therefore, this study implements a multi-site measurement verification to establish the relationship between the wind resources of the nearshore wind turbine system and a potential offshore power site in Chanbin. In the absence of a wind turbine at a specific location, potential of offshore wind energy is analyzed through wind resources. The findings showed that although the distance between these two sites is substantial, the nearshore and offshore areas at Chanbin experience similar wind conditions, and nearshore wind turbine can respond well to changes in wind speed and generate power accordingly. Afterwards, on this basis, the offshore power potential was evaluated and compared with the nearshore wind turbine systems. The results suggested the advantages of offshore wind power. A further analysis of the differences between power generation on a monthly basis was carried out to determine the distribution of wind turbine operation modes and illustrate the influence of the NE monsoon.
