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!
PO111: Improving the accuracy of mesoscale wind data through monthly and directional calibration using 10-minute average SCADA data
Juliette Krug, Project Engineer - Onshore Renewables - Renewables, Tractebel
Abstract
Historically, the financial viability of wind farm (WF) projects was mainly based on the Annual Energy Production (AEP) coming from the Energy Yield Assessment (EYA). However, with the increasing penetration of renewable energy in the market, which is characterized by more volatile production, green energy prices are fluctuating more frequently. This volatility, in combination with complex business plans due to the global context, highlights the importance of predicting accurately the production at a specific moment (e.g., particular months or wind directions). Relying solely on key probability figures from the AEP is no longer sufficient. Greater precision is essential to assign accurate pricing to the time-varying energy production and to determine the necessity of new services, such as battery storage or frequency control reserves. A previous study presented at WindEurope 2023 demonstrated an approach for accurate EYA for wind projects without requiring measurement campaigns. This methodology, extensively developed for Belgium, makes use of the EMD-WRF Europe+ mesoscale dataset calibrated with 10-minute average SCADA data from operating WF. Currently, mesoscale dataset calibration has been performed using the AEP of existing WF. However, this annual calibration can be insufficient when results are analyzed for specific directions or months. The study examines the use of monthly and directional calibration coefficients, derived from SCADA data of existing WF in Belgium (sample of 14 WFs), to estimate the monthly and directional energy production of nearby WFs. While using monthly coefficients shows limited interest in comparing AEP (improvement of less than 0.1% of AEP compared to annual calibration), it brings large improvements of more than 20% of error reduction on specific months. Due to local effects, directional calibration coefficients can lead to increasing error in specific directions. This methodology should certainly be considered for WF repowering and extension, where it will lead to large improvements.
