Reflecting on the recent EWEC2010 Proceedings and the build-up to the European Wind Energy Association (EWEA) 2011 Conference, as a wind energy expert, I find myself both impressed and humbled by the massive collective effort put forth to advance our industry. The initiative to propose a harmonization of grid code requirements across Europe, as presented at the 2010 convention in Warsaw, is particularly noteworthy. Such efforts are critical in overcoming the bureaucratic and technical obstacles that often hinder the rapid deployment of wind energy projects.

The focus on issues like the advertisement wars in the UK, as highlighted by David R. Jones, and the extensive discussions on wind farm development, resource assessment, and the future of renewable energies, underscores the complexity and multi-faceted nature of the challenges we face. As professionals in this field, we're all too familiar with the labyrinth of regulations, the technical hurdles, and the significant coordination required among various stakeholders to bring a wind energy project to fruition.

In celebrating the successes of our colleagues and the advancements in our field, the suggestion of rewarding the Herculean efforts with Superman trophies, or at least Superman Tees, is a delightful one. It’s a symbolic gesture, yet it speaks volumes about the recognition of the extraordinary efforts required to make significant strides in wind energy development. It’s these small acknowledgments that can boost morale and encourage a sense of camaraderie and achievement within the community.

This conference and others like it are indeed eye-openers, showcasing the latest technological advances, discussing regulatory challenges, and sharing insights into the future of wind energy. The collaboration, discussion, and exchange of ideas they foster are crucial for propelling us towards our common goal of a sustainable, carbon-neutral future. As we continue to navigate the complexities of our industry, let's take a moment to applaud those who have achieved success against all odds and continue to push the boundaries of what is possible in wind energy.

ABSTRACT ID:  583

Track: WIND RESOURCE  Topic: WIN02 Offshore wind resource assessment

OFFSHORE WIND RESOURCE SITE CHARACTERIZATION USING WRF MODEL, RESULTS FROM FIRST VALIDATION TEST

Wind turbine technology has achieved a challenging development in the last years towards a real offshore wind power penetration. The engineering barriers have been overcome and now it is required a more specific and detailed spatial planning of the offshore resource to support the foreseen role of the wind power production coming from the seas. Offshore wind resource characterization is dramatically constrained by the enormous cost of obtaining on-site windmast data. On the other hand, satellite derived information provides wide spatial  estimation of surface variables but can not fulfill the resource information demand due to height,  spatial resolution and time sampling limitations.

Atmospheric numerical modelling is the main and effective technique to map resource up to very near offshore wind farm scale. This work will show different improvements to adapt WRF regional atmospheric model for real offshore turbulence and bottom boundaries conditions for different regions.

Main focus will be given to atmospheric stability mechanism and adaptation of turbulence schemes via drag adjustment to surface topology.  Enhancement of boundaries conditions will also benefit of  satellite data assimilation and wind wave models coupling. An innovative semi-LES approach is also presented here. This work will also cover extreme wind characterization on the sea/ocean climatic context based the gained experience on onshore extreme conditions mapping. WRF improvement features for offshore wind modelling are part of the seamless modeling approach of the global wind resource conditions carried out by Vortex during the last 3 year whit special emphasis on a intensive on-going validation exercise against offshore data measured by developers and manufacturers. The verification of WRF offshore  results were made in collaboration with  Vestas and  Natural Power

REMOTE SENSING

Theme: WIND RESOURCE
Monday, 14 March 2011, 16:00 - 17:30
Room: Auditorium 700

Session description
The use of LIDAR for wind speed measurements is still increasing and therefore competing with cup anemometry. Through experiments, experience is being built up in various conditions and will be presented in this session. LIDAR is important especially for project developers and wind turbine manufacturers but in fact for all who use wind measurements. The session will provide the state of the art of LIDAR in different circumstances.

Experimental results based on a comparison of onshore and offshore measurements will be presented for floating LIDAR. The uncertainty of LIDAR measurements in complex terrain will be investigated by comparing measurement results in different terrain types against mast data. Finally, in an interactive discussion, three presenters will go into the use of a nacelle-based LIDAR for power curve measurements and share their experiences.

WAKES

Theme: WIND RESOURCE
Tuesday, 15 March 2011, 09:00 - 10:30
Room: Auditorium 700

Session description
Reducing the uncertainty in the prediction of wake effects is of vital importance for large wind farm developments. Wakes not only impact the energy production but also increase the loading a wind turbine will experience. In the offshore environment evidence suggests that wakes persist far more than they do on land and as a consequence are a major design driver.

This session brings together a number of papers which present numerical wake models of varying complexity ranging from CFD to “engineering” models. Experimental data will be presented to assess the accuracy of the models. The session will also explore a novel technique for measuring wakes using separated non-aligned LIDARs.

MESOSCALE MODELLING

Theme: WIND RESOURCE
Tuesday, 15 March 2011, 11:00 - 12:30
Room: Auditorium 2000

Session description
Mesoscale models are beginning to be used in the wind energy sector for wind resource assessment purposes. The advantages of using these atmospheric models to study the wind potential are clear: simulation of the wind field (plus many other atmospheric parameters) with a spatial resolution in kilometre-scale covering big domains of more than 1000 km x 1000 km, the possibility to simulate any region of the world without local measurements, etc. However, there is a need to understand the uncertainties of such models, especially when dealing with wind energy.

During this session, mesoscale model users, wind resource assessment and prospective staff will provide an overview of the state of the art and innovative applications of mesoscale models in wind energy, together with information about challenges, uncertainty and integration examples of the data generated by these atmospheric models.

FORECASTING PREDICTION

Theme: WIND RESOURCE
Tuesday, 15 March 2011, 16:00 - 17:30
Room: Auditorium 2000

Session description
Wind power forecasting has reached a mature stage in the last years. This session will showcase what can be called the ‘third generation’ prediction models, which go further than the deterministic forecast of power production over the coming days. Concerning meteorology, the benefits of ensemble forecasts in Europe will be demonstrated, showing the potential of this source of probabilistic predictions and the expected accuracy.

Because wind power will become the main source of electricity in an optimally interconnected Europe, the effects of spatial forecast error smoothing on a European scale will be quantified and visualised in this session. Moreover, specific extreme events and large errors, e.g. during ramps or icing, are of vital importance for the management of our electricity systems. The last two presentations will deal with the challenges related to forecasting those events.
