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.
PO116: Atmospheric stability driven time switching wind fields to improve EYA
Graeme Watson, Principal Energy Analyst, Natural Power
Abstract
Energy yield assessment (EYA) remains a challenge in complex sites with insufficient representative anemometry coverage. The standard approach of considering a single wind resource grid (WRG), that varies by direction only, to represent the average atmospheric stability conditions can present considerable cross-prediction errors when studied on a time series basis. The “average” directional WRG approach can show good performance by virtue of errors cancelling out and remaining “invisible” when viewed on average, but ignorance of temporal errors can cascade from wind speed modelling through the full EYA modelling chain to result in biases in performance when compared to real world SCADA data. It is suggested that seasonal and diurnal variations should be assessed in detail, especially in complex sites and while simple day/night binning as a stability proxy offers benefits, it does not capture the nuances of the factors that drive site wind speed variations.
