Integration and control of wind energy in power systems Areas of research To develop methods and models for wind farms operating as active wind power plants with ancillary service capabilities supporting power system stability and control To develop, validate and disseminate methods and models for wind power variability and uncertainty supporting power system studies Convener of IEC standard for wind power plant models Experimental validation of wind power plant capabilities Inclusion of other weather dependent RES generation such as solar PV in variability model portfolio P, Q (dd-1):12:00 dd:(hh-1):30 dd:hh:mm Offshore ReGenCon Communication Transmission Grid P, Q P, Q DA Spot Market (IPP) Intraday Market (IPP) HA Balancing Reg. power (TSO) Real time Balancing Reg. power (TSO) Manual / Automatic Reserves (TSO) Distribution Grid P, Q Market model Balancing Realtime balancing and reserve model Onshore ReGenCon Communication DA prognose ID prognoses HA prognose online prognose real production CorWind 18

18 4. Planning and Development of Wind Farms Areas of research Siting and Integration: Cost, development time & social acceptability in a multi-disciplinary approach Design and operation of wind farms in cold climates Wind energy for electrification in isolated (island/off-grid) power systems Integrate knowledge for wind farm planning technical and social Tools for developers and planning authorities, including tools for evaluation of human perception of noise from onshore wind farms 19

19 Products and software Our work leads to innovation in the form of software products, consulting services, guidelines, standards and certification procedures; this is in cooperation with international programmes, industry and government agencies. Our development and dissemination of meteorological knowledge and tools also further enable innovation within the industry Wind energy industry-standard software Online WAsP web platform (mywindturbine.com) Bringing resource calculation onto a web platform and tapping into dataset on the Global Wind Atlas Global Wind Atlas web platform (globalwindatlas.com): Bringing our method and hi-res datasets to society. Numerical Wind Atlas projects: Application of our mesoscale and microscale modelling methodologies, and training on application of the results. 20 GWA validation and uncertainty Consultancy providing wind and meteorological data: Application of 07/11/2018

20 Design New airfoil design methods are developed, e.g. using: Advanced flow prediction Numerical optimization with focus on improving: Aerodynamics Aeroacoustics Structural performance 21 7 November 2018

21 Modelling Models are developed for prediction of steady and unsteady aerodynamic loading. The plot on the right shows a wake predicted using a free wake made of vortex filaments and with turbulent inflow. Simulation models are developed for noise emission from wind turbine rotors and validated by comparison to full scale measurements. The picture on the left shows measurements of the far field noise emitted by a 500 kw NordTank wind turbine at IEC standard observer position and the comparison of the predicted and measured spectra November 2018

22 Modelling - Multidisciplinary Windfarm CFD - Wind farm wakes and layout Actuator Disc Rotor CFD - EllipSys3D Actuator Line Fully Resolved 23 7 November 2018

23 Experimental Work Full scale measurements are carried out to test airfoils and blades in atmospheric conditions and under influence of centrifugal and Coriolis forces. The plot below shows a result from the DANAERO test (to the right) November 2018

24 Experimental Work Wind tunnel tests are carried out. Poul la Cour Tunnel (below), The Danish Aerodynamic and Acoustic Wind Tunnel will be completed in Focused on aerodynamic and aeroacoustic measurements, it will be used for validation of models and understanding aerodynamics and aeroacoustics. The rotating test rig (abowe) allows for aerodynamic, aeroelastic, aeroservoelastic and aeroacoustic experiments in the rotating frame in atmospheric conditions. Different elements can be mounted for characterization of airfoil characteristics based on pressure measurements and testing of pitch and active flap control systems November 2018
