PO078: Understanding tropical cyclone characteristics impacting wind farms
Jake Badger, Head of Section, Resource Assessment and Meteorology, DTU Wind and Energy Systems
Abstract
This presentation discusses some projects at DTU Wind examining behaviour of Tropical Cyclones with a view to understanding their full implications on wind energy. In the first study attributes such as paths, intensities, maximum wind speeds, frequency and radius of maximum winds, have been determined for US East Coast, Taiwan, and Japan. These areas are chosen because of wind farm development interest there. Three different data are used to assess[KC1] [JB2] the tropical cyclone attributes, namely, the Best Track Archive for Climate Stewardship (IBTrACS), ERA5, and CFSR. Analysis presented in the talk will quantify the agreement between the datasets, and identify strengths and weaknesses. Preliminary results are expected to reveal regional variations in Tropical Cyclone behaviour, provide insights into the comparative performance of ERA5 and CFSR for specific Tropical Cyclone metrics, and highlight any biases or gaps in the IBTrACS data. This work contributes to the development of region-specific wind turbine design criteria and improve the accuracy of wind field modelling in Tropical Cyclone prone areas. Another study looks at providing improved turbulence fields for tropical cyclones. Wind fluctuations on scales larger than a few minutes can affect wind turbine loads but are not yet adequately described in current practices for determining turbine load cases. This study combines mesoscale and microscale turbulence fields, in order to improve the description of turbulence. The microscale turbulence field is modelled with the Mann Turbulence model, and the mesoscale wind fluctuations are obtained from mesoscale simulations. Fluctuations in wind shear and veer are included. Validation is performed using sonic anemometers. It is found that the method can capture properties of the turbulence field during a Tropical Cyclone. The study provides a framework for assessing the relative importance of wind speed, shear, veer, and micro- and mesoscale turbulence on wind turbine loads for a large number of different tropical cyclones.
