Effects of wind farms and turbines on flow and meteorology
SESSION DESCRIPTION
In this session the audience will learn about a range of studies looking at wind measurements, production data and modelling, in the context of how wind farms impact flow and other meteorological quantities, upwind as well as downwind. Different scales are explored, ranging from individual turbines, within wind farms, to wind farm cluster scale. Modelling approaches and the balance between demands for fast modelling techniques as well as accurate results are discussed. The presentations address the complexity of meteorological conditions and feedback the wind farms have on that complexity, such as atmospheric stability and turbulence.

UL wind software’s latest evolutions
Sponsored session by UL
SESSION DESCRIPTION
This side event by UL will cover some of the most relevant topics required in the preconstruction stage as well how those jobs will have a follow up during the operational life of the assets. Not connecting both sides might cause a partial standpoint. The main driver of the presentation will be energy estimate. For the preconstruction, we consider three main areas to cover. All of them require a perspective as a totally digitalized work flow process, so, scalable, trustable and accurate. The growing targets by many utilities, as well boosting process by oil&gas groups, require those drivers.
Firstly, we want to share latest updates on wind flow modeling. We recently finished a new updated comparison between existing options, and it is convenient that audience know most relevant aspects of UL results. Again, on a perspective of scalability, trust and accuracy we want to share our latest results. For data analysis, when on site measurements are available, our expert Tom Lambert will share the new updated tool that empower the analysts, who should do more with less, as well looking to new challenges caused by newer technology (more hub height / more rotor diameter). And, finally, we want the audience to hear from Nick Robinson, how we are managing the design of a wind plant in order to get the most convenient design, considering the entire list of constrains for a wind plant design. This include also uncertainty estimate, as it is a must when running the financial model. More than a sophisticate set of tools, UL also manage an entire suit (WRAP) that empower wind engineers for a unique environment, where the analysis become easier than ever. Each plant is unique, each business model is different, UL will share our experience from the most sophisticated tools up to the more friendly work environments. All this analysis will be nothing if it’s not connected with the energy estimate on the operational life. Again, UL like to share what is needed to develop such analysis. The unique tool, RAMP, is the environment required by owners, asset managers, when is needed to monitor 24×7 the performance of the assets, with a focus on lost energy. Each kWh matters.SPEAKERS

Optimising operations
SESSION DESCRIPTION
Optimising Operations is a key driver in the success of this industry, data driven complex analytics is enabling the next leap development to drive down cost of energy. In this session we will learn from key insight on how to optimise performance through gained knowledge from an assessment of wind turbine performance deterioration performed with the support of machine learning, but also how to use new technology to enable lifetime extension assessments. We will also have deep dives regarding drop control at grid frequency increase, real time Scada enabled Ice risk forecast.

Control Strategies
SESSION DESCRIPTION
In this session different applications of control strategies will be demonstrated. We will see how the turbine can be yawed to adapt to local conditions, we will then see how to optimise under curtailed conditions. We will then use two instruments: a night vision system for blade impact detection, and a lidar for turbine control.

Advancements in Tools and Datasets
SESSION DESCRIPTION
In this session participants will learn about recent advancements in tools and datasets. A number of techniques will be discussed ranging from the use of artificial intelligence to extract a time series from WRF based on uncertainty through the extraction of turbine design parameters from a wind atlas to the estimation of the wind resource at hub heights from data derived from synthetic aperture radars. Additionally participants will learn about a comparison between ASCAT satellite data and that derived from WRF simulations.
