Policy Studies

– ECN is the largest, independent, market oriented and innovative Dutch energy research institute.

– ECN investigates and develops technologies and products for a safe, efficient and environment-friendly energy supply with 600 fte.

– With and for the market the energy technology is developed by ECN.

ECN Wind R&D Strategy

Offshore Wind Power Plants

Planning & Design

Construction Operations

Reduce COE of Offshore Wind Power Plants

80% of EU offshore wind farms have been realised

with ECN support

Top industrial players are exploiting ECN

technology and knowledge By 2015 ECN will have facilities for

14MW+ prototype turbines

R&D Line 1 – Support structures

• Design support for support from integral perspective

• Monitoring of loads / residual lifetime during piling and operations

• Planned to be involved in piling experiment in 2014 to test sensors

• External conditions: study of waves in WIFI-JIP, wind conditions in various

• Innovative support structure concepts (with Dutch industry)

• Controller to minimise weight of floating support structure (EU Innwind)

R&D Line 2 – Wind power plant

and its components

• Integrating wind farm design tools: combine wake losses, electric losses, loads or residual lifetime, grid connection and calculate costs.

• Wind farm control in combination with lay-out designs to maximise production at minimum mechanical loads

• Implementation and demonstration of wind farm control

• ECN-coordinated EU project AVATAR for developing advanced aerodynamic models incl. Mexico Experiment for validation

• Support to XEMC-Darwind and 2BEnergy in FLOW projects – a.o. controller and support structure design support

Wind Farm Control

• Yaw upstream turbine : – Less power (higher loads)

– Yaw deflects wake

• Downstream turbines yield higher production

• Expected gain » 1-1.5 %

• Experiments in offshore wind farm for 2014 under discussion 8

R&D Line 3 – Wind power plant

electric network

• North-Sea Transnational Grid: development and validation of multi-terminal HVDC controller

• TKI synergy at sea: R&D on business case and technical design of interconnecting wind farms in the North Sea

• Development of optimisation methods for the electrical infrastructure in the wind farm and application to ‘Doggerbank-like’ scenarios

R&D Line 4 – Transport,

Installation and Logistics

• Support to industry to develop access systems from integral approach of offshore wind farms and cost modelling

• Example: Z-Bridge project within TKI

• Development of cost model for installation of support structures (based on O&M Tool)

• Possible projects: – Monitoring loads during transport and installation

R&D Line 5 – Operation and

Maintenance

• OPEX Cost Modeling

• Optimise and implement Wind Farm Data Collection: – key information from unstructured data

• LoadWizard Load Monitoring – integral solution for optimising the O&M strategy based on encountered loads

– consists of measurement hardware and software (FOBM), software for load prediction at all turbines (FleetLeader) and OPEX modelling for maintenance strategy optimisation (OMCE).

• O&M Optimiser – quantifying the consequences of short-term decisions allows for better decision

making and a reduction in OPEX and increased revenues

• Final stage for Fibre Optic Blade Monitoring (FOBM) – High accuracy, low maintenance, no re-calibration over lifetime, can be retro-fitted.

R&D Line 6 – Wind power plant

development

• Daily Power Forcasting by ECN for Windunie

• Cost modelling – valuation of innovations

• Storage Solutions – For large-scale implementation of renewable energy in a renewable electric system

– Cost-benefit analyses for storage systems

• Development of a sub-programme in EERA on socio-economic aspects

R&D Line 7 – Facilities and

Experiments

• Testing of prototypes at ECN testsite Wieringermeer

• Application of Lidar systems to Wind Power – Development of mobile windscanner.eu facility

– Demonstrating LIDAR on test turbines

– Collaboration project with NORCOWE

• Meteorological programme at North Sea – Three measurement locations

– Understanding wind conditions

• Open-facility scale wind farm envisioned (EERA partners + EU + TKI)

Lidar systems at operation

14 17-10-2013

• Meteo mast IJmuiden • Offshore • 75 km from IJmuiden • At the height of Callantsoog

• EWTW • On shore • Flat, agricultural terrain • About 35km from ECN

• ‘Lichteiland’ Goeree • Offshore • KNMI measurement station • About 30km from shore

R&D Facilities and TKI Projects

• Wind turbine test site Wieringermeer: – Five R&D turbines

– Six prototype test locations

– Scale wind farm

– Offshore Measurement mast + Lidar

– Under development:

– Leeghwater to demonstrate innovations with industry

– Testsite Groningen to test large offshore turbines

• TKI Projects (ECN inside) – LAWINE – Optimisation of wind farms by

application of LIDARS

– Z-Bridge – Assist to develop acces system

– Synergies at Sea (SAS) – optimisation of electrical grid and interconnectors; development offshore sub-station

– Design for Reliability (D4REL) – making wind turbines more reliable

• TKI projects aim at reducing cost of energy and support the Dutch industry to create green jobs.
