Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO122: Validity and applicability of mesoscale wind farm parametrization and LES offshore wind farm wake models
Rémi Gandoin, Senior Specialist and Product Development Manager, C2Wind
Abstract
Accounting for mesoscale flow features when assessing wake losses is becoming increasingly relevant for offshore wind farms, as wake conditions depend on the structure of the Atmospheric Boundary Layer (ABL), including atmospheric stability and internal boundary layers. Legacy models (Jensen, TurbOPark), as well as steady-state CFD remain widely used. Such models can be tuned to account for the ABL structure, either heuristically or using synthetic flow cases. However, such adaptations require multiple wind farm SCADA datasets for tuning and validation and may not apply to regions (US, APAC) where mesoscale phenomena are unique and complex. Mesoscale and LES weather models inherently account for the above-mentioned ABL features and can be extended with wind farm and wind turbine parametrizations. These models directly solve the equations of atmospheric flow, and essential features (blockage, external/internal wake) and their interactions are inherently represented. However, their validity is yet to be demonstrated to the same extent as legacy models. Works presented at the WindEurope Technology Workshop 2024 show that only few 3rd party validation studies have been published, and that differences between models remain unexplored. Additionally, the integration of these models within the yield assessment toolchain is rarely addressed. The present study explores the validity and applicability of two commercial (meso and micro-scale) weather models in wind farm modelling, in conjunction with engineering wake models. It does so firstly by validating analytical legacy models and the two commercial weather models against public in-situ measurements (primarily) as well as satellite wind datasets (SAR) and publicly available wind farm power time series (as secondary sources). Secondly, using a reference wind farm cluster, their applicability in an EYA process is assessed and recommendations are provided. Overall, this study aims at providing a pragmatic and quantitative contribution to the current wake effect modelling discussion.
