Description
Offshore wind turbine installations increase around the globe. The advancing floating wind turbine technology enables the installation of wind turbines further offshore in areas with greater water depth (> 50 m). This makes it feasible to erect wind turbines in previously unexploited areas in the East Asia waters. At the same time, the Taiwan Strait is impacted by extreme weather events like typhoons, which brings new challenges to the modeling of wind farm wake effects and wind-wave interactions for wind energy applications. Therefore, this study explores wind farm wake effects and wind-wave interactions in tropical cyclone conditions.We use Typhoon Megi, a category 5 cyclone that hit Taiwan during late September 2016, as an example (following Müller et al. 2022) to study the relevance of wind-wave interactions and the effect of wind farm wakes on the development and impact of the typhoon. To do so, we apply the Coupled-Ocean-Atmosphere-Wave-Sediment Transport Modeling System (COAWST; Warner et al. 2008, 2010) equipped with the Wave Boundary Layer Model (WBLM; Du et al. 2017, 2019). The WBLM ensures that exchange between the atmospheric model WRF (Weather, Research and Forecasting model) and the wave model SWAN (Simulating WAves Nearshore model) are flux and energy consistent.
We perform simulations of different complexity by activating individual components of the modeling system: We compare atmosphere-wave coupled simulations with atmosphere-only simulations and include scenarios with and without wind farms. In the scenarios with wind farms, we take both existing and planned future wind farms into account.
First results show that wind-wave interactions influence the intensity and track of the simulated typhoon and that the existing and planned wind farms modify the wind and turbulence, causing changes in the typhoon passage over the Taiwan Strait.
