Dear friends and colleagues of IRPWindWelcome to this 2nd annual conference of IRPWind. We have

now been well under way with the integrated research

programme for wind energy for 1.5 years. The essence of

IRPWind is to take important steps towards further integration,

alignment and coordination of research activities in Europe.

In order to satisfy our ambitious goals, we need to have a forum, where various stakeholders

can meet and discuss future transnational collaboration. The IRPWind yearly conference is

a unique meeting place and we are delighted to welcome our colleagues from the research

community, the wind energy industry as well as the representatives from the European

Commission. During the next 2 days we are gathered to discuss and disseminate IRPWind

results. The conference comprises parallel sessions at sub-programme level as well as

plenary talks from important stakeholders. Several technical and collaborative gaps currently

hampering the next generation of wind energy technologies will be discussed. On day 2 we

will have a side event with the aim of identifying new collaboration opportunities between

industry and IRPWind. I have high expectations for this.

In the first year of IRPWind the mobility programme got off to a good start with first

exchanges of staff commencing based on 12 applications for exchange. During the first

year we also produced an IRPWind report on outlining a strategy on access granting to

data. This report will be the basis for future work in IRPWind to enable better access to data.

IRPWind partners plan several actions to realize our ambition of being good role models

such as to ensure a public list of available data sets. Both issues will be addressed during the

conference.

Once again, welcome to the 2nd annual IRPWind conference. I hope we will have 2 days

with inspiring discussions on the future for our European Integrated Research Programme for

Wind Energy.

Integrated Research Programme WindThe aim of the IRPWind is to foster better integration of European research activities in the

field of wind energy research with the aim to accelerate the transition towards a low-carbon

economy and maintain and increase European competitiveness. The IRPWind is expected to

both benefit existing priority settings as well as to improve the quality and implementation of

future priority settings through the coordinating effect on the research communities.

An objective is to integrate the various capacities and resources in the joint research

activities, described in this IRP, with other ongoing European and National projects carried

out by IRPWind partners and/or other members of the European Energy Research Alliance

Joint Programme Wind.

The IRPWind and EERA joint programme on wind energy provides the strategic leadership for

the medium to long term research to support the European Industrial Initiative on Wind

Energy in the framework of the Strategic Energy Technology (SET) Plan and provides added

value through:

Strategic leadership of the underpinning research

Joint prioritisation of research tasks and infrastructure

Alignment of European and national research efforts

Execution of coordinated and structured research in medium to long-term programmes

Coordination with industry, and Sharing of knowledge and research infrastructure.

Poster abstractsMonitoring of offshore foundations for design optimisation, O&M decission support and life time assesement: an overview of the activities of OWI-Lab

Christof Devriendt, Wout Weijtjens, Nymfa Noppe, Tim Vebelen, Gert De Sitter

An overview of the foundation monitoring activities of OWI-lab, the Offshore Wind Infrastructure

Lab, will be given. OWI-Lab develops mid- and long-term monitoring solutions for offshore wind

turbines. OWI-lab is currently continuously monitoring 3 monopile foundations and 2 jacket

foundation within the Belgian north sea The motivation is gaining the insights that are crucial to

minimize construction and installations costs of future offshore wind farms and to extend the life

time of existing structures and reduce their operation and maintenance costs.

SHM approaches of offshore wind turbine substructures: application on simulation data

Operation and Maintenance (O&M) costs constitute 20-25% of the total levelised cost per kWh

produced over the lifetime of an offshore wind turbine. A very substantial reduction in O&M costs

through new technological concepts is hence a challenge, and the remote evaluation of actual

status of the whole system is the starting point for the potential improvement.

This poster presents a collaborative proposal between IK4, CTC and CENER in order to im-

prove existing structural health monitoring approaches to detect possible failures on floating

substructures including mooring and anchoring systems based on simulation data obtained from

dynamic simulation codes.

Robust Controller for Load Mitigation in a Commercial 3 MW Wind Turbine

Aron Pujana-Arrese1, Iciar Font2, Carlo-Enrico Carcangiu2 and Joseba Landaluze1

1IK4-IKERLAN. Arizmendiarreta, 2, E-20500 Arrasate-Mondragon, The Basque Country, Spain2ALSTOM RENOVABLES. Roc Boronat, 78, E-08005 Barcelona, Catalonia, Spain

The design and analysis of different robust control strategies applied to a commercial 3 MW wind

turbine is presented. An exhaustive simulation analysis is developed with the proposed robust con-

trol strategies and it is compared to the baseline control strategy installed in the commercial wind

turbine in terms of Key Performance Indicators (KPI). The family of linear models extracted from a

high-fidelity aeroelastic code is used to design the robust control strategies and this software pack-

age is also used to perform a full set of calculations including both extreme and fatigue load cases.

The control objectives for the novel proposed robust control algorithms are improving the regula-

tion of the generator speed, mitigating the wind effect in the tower fore-aft and side-to-side first

modes and damping the drive train mode with the main objectives of mitigating the loads in the

wind turbine and improving the generation of electric power.

Overall, the results obtained from this study are very promising in terms of loads and performance.

Load levels are generally aligned with the baseline controller, and even allowing some extra load

reduction, which is a good result considering that the baseline is a mature turbine product.

The work presented in this paper is the first fundamental step for the implementation of advanced

robust controllers in real commercial wind turbines. Moreover, the robust control strategy has been

integrated into the whole control software package and validated through HIL, confirming the

capability of the current control hardware to work with such high ordered state-space represented

robust controllers. The following step consists in performing a comprehensive field test campaign,

in order to complete the validation cycle and make this solution available for industrial applications.

An overview of the foundation monitoring activities of OWI-lab, the Offshore Wind Infrastructure

Lab, will be given. OWI-Lab develops mid- and long-term monitoring solutions for offshore wind

turbines. OWI-lab is currently continuously monitoring 3 monopile foundations and 2 jacket foun-

dation within the Belgian north sea The motivation is gaining the insights that are crucial to mini-

mize construction and installations costs of future offshore wind farms and to extend the life time

of existing structures and reduce their operation and maintenance costs.

3 Experimental and operational structural dynamics identification of the laboratory scale offshore support structure with uncertainty assessment.

Marcin Łuczak

Institute of Fluid Flow Machinery, Polish Academy of Sciences

The poster presents an experimental campaign on the laboratory scale model of the tripod

type offshore support structure. The model structure was tested in the different support and

environment configurations: free-free, supported and in the large towing tank conditions. Tripod

model allows to model the propagation of the circumferential crack of the cylinder. The towing

tank test configuration included the wind tower with the 3 bladed rotor. Rotary support allowed to

expose the tested structure to the waves coming from different angles. Test campaign accounted

for the different types of sea waves. For the reference modal model of intact and damaged

structure impulse modal test was performed with the stopped rotor and calm water conditions.

The response of the structure to the wave were measured with 4 bi-axial underwater

accelerometers located on the submerged part of the model and 4 tri-axial accelerometers located

on the above-water components. Experimental and operational modal analysis were applied to

identify the structural dynamics of the investigated laboratory scale model for intact and damaged

state, different support and wave patterns. Numerous modal models consisting of the natural

frequencies, mode shapes and corresponding damping coefficients were estimated from the

measured signals. Comprehensive test matrix allowed to assess the differences in modal model

parameters due to the damage, support and environmental loads.

Windcrete: Proof of concept

Climent Molins

Universitat Politècnica de Catalunya UPC - BarcelonaTech

A proof of concept of a monolithic concrete SPAR platform for FOWT was developed in the

framework of the AFOSP KIC-InnoEnergy project (Alternative Floating Platform Designs for

Offshore Wind Towers using Low Cost Materials). The AFOSP project consisted in a series

of experimental and numerical studies aimed at proving the feasibility of the concept and

demonstrated promising CAPEX and OPEX reductions. The members of the AFOSP consortium are:

GNF, University of Stuttgart and UPC.

The experiments comprised a set of hydrodynamic tests performed in the CIEM wave flume facility

at the UPC, with a 1:100 scale model assuming Froude similitude. The complete experimental

campaign included free decay tests, a set of 22 regular wave trains of different periods to determine

the RAO’s and another set of 21 regular and irregular wave trains in conjunction with a mechanical

wind device, simulating the mean thrust force exerted by the wind turbine.

Numerical studies were intended to verify that the design is stable when subjected to design load

case (DLC) according to the IEC. These studies consisted in coupled dynamic simulations including

the mooring system, the controller and the structural dimensions for a particular location, using

the certified coupled aero-servo-hydro-elastic code FAST. IEC load situations include different

environmental conditions and technical conditions of the floating system including failure cases.

5 Modelling Complex Systems: The North Seas Offshore Grid and Future Research.

The North Seas offshore grid has two main functions, to connect offshore wind farms and

to interconnect power systems in Norther Europe. Many projects address this grid, given its

importance and it being a priority for the European climate and energy policies. Nonetheless,

studies vary in a number of features, and thus to guide future research a review is conducted

of published works since 2010. This review develops a simple and effective methodology that

can be applied to other energy systems models. It jointly considers the studies of interest, the

system characteristics, a categorization framework and relevant indicators. Most studies focus on

investment and operation of the grid using optimization models, but differences in assumptions,

methodology and detail of results publication limit their comparability. Nonetheless, integrated

typologies frequently present economic, operational and environmental benefits, although

the reviewed studies do not unambiguously warrant immediate and full cooperation on grid

governance. Lastly, future research should be attentive to the presentation and resolution of data,

assumptions and results, as well as consider the grid characteristics that define system performance

and dynamics.

Multi-scale procedure for modelling shear-web and spar-cap joint of wind turbine blat

The work focuses on the development of an automated approach that combines a detailed two

scale structural finite element model of the blade, the Blade Element Momentum approach and 2D

CFD code for modelling a blade under stationary wind conditions considering aerodynamic, inertial

and gravitational loads. The approach should provide more accurate stress-strain values than the

current beam based approach especially when composite and adhesive progressive damage are

considered in the model. It also requires significantly less computational time than the strong-cou-

pled CFD-FEM approach.

Besides macro-scale response of the blade, a more localized analysis of a particular subcomponent

can be carried out using sub-modelling approach. In this case the approach has been used for pre-

dicting stress-strain and failure of the adhesive between spar-cap and shear-web joint.

Reduction of fatigue damage equivalent loads In the wind turbine system through the use bending-twisting coupling induced in composite wind turbine blades.

Altan Kayran

METU Center for Wind Energy

The effect of bending twisting coupling induced in wind turbine blades is investigated for its ef-

fectiveness in reducing fatigue damage equivalent loads (DEL) in the whole wind turbine system.

Baseline full GFRP blade and bend-twist coupled blades are also compared in terms of stress in the

critical blade section, tower clearance, dynamic characteristics and cost of the blade. The use of

CFRP material in the main spar caps of bend-twist coupled blades is specifically investigated for its

effectiveness in reducing damage equivalent loads in the whole wind turbine system.
