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!
PO145: CFD correction of RSD data: analyzing the impact of thermal stability
Thales Delmiro, Project Engineer, CDV Desenvolvimento
Abstract
Remote Sensing Devices (RSDs), particularly Light Detection and Ranging (LiDARs), offer significant advantages over traditional met masts in wind resource assessment, such as better mobility and the ability to measure at greater heights. However, RSDs have limitations in the precision of their measurements in complex terrains due to flow heterogeneity and technological constraints. A previous study compared various methodologies for RSD measurements in complex terrains using Computational Fluid Dynamics (CFD). While the study successfully improved the accuracy of Annual Energy Production (AEP) calculations by correcting wind speed data measured by RSDs, discrepancies of over 10% persisted in the most complex site analyzed. To address the remaining errors, this subsequent study focused on adjusting the thermal stability of the CFD simulations, only using the best-performing CFD software/methodology from the previous study. Unlike previous simulations, which assumed a neutral thermal stability for all simulations, the new analysis incorporated varying thermal conditions, according to on-site measurements using the Svenningsen method, which uses the wind shear and the turbulence intensity to calculate the stability, and, when applicable, the temperature gradient method. Given the tendency of complex sites to have stable atmospheric conditions, incorporating thermal stability adjustments is crucial for more accurate wind resource assessments in these locations.
