Remote sensing sensitivities workshop builds momentum towards transition from scalar to vector wind reconstruction
Paris, France, 18th June 2018. As part of an event organised in Vilnius last month by WindEurope, Deutsche WindGuard and Leosphere held a joint workshop to explore remote sensing sensitivities and showed ways to reduce them.
At the event, Deutsche WindGuard presented the results of the third independent classification campaign it recently conducted to assess the Windcube ground-based lidar sensitivities to environmental conditions following the IEC 61400-12-1 ed2 2017 standard. An in-depth explanation of the results was presented by Leosphere, as well as a way to reduce sensitivities further by using vector averaging. It is expected that the findings will be beneficial for most remote sensors.
Key points covered at the workshop included:
– the sensitivity of Windcube RSDs in certain environmental conditions. Deutsche WindGuard’s tests indicated deviations from cup anemometers of around 4% at low wind speeds in specific conditions. This sensitivity was found to be primarily the result of uncorrelated turbulence on RSDs based on lidar-pulsed technology using scalar averaging for the reconstruction of wind spee-
-the use of a vector definition of the wind to remove the discrepancy between this data and figures obtained via cup scalar averaging, resulting in a close match between RSD and cup across a large span of turbulence intensity1.
-the observation that exploratory work for wind speed calculated via velocity azimuth display (VAD) shows sensitivity to turbulence intensity in the opposite direction. It was noted that further study is needed to confirm this observation.
Axel Albers, managing director of Deutsche WindGuard, said, “Scalar averaging has been identified as a key driver of the relatively high sensitivities of the wind speed measurement by monostatic RSDs on environmental variables. By the implementation of vector averaging, the measurement uncertainty due to the sensitivities is reduced significantly. As a consequence, it is expected that scalar averaging will be replaced by vector averaging in the standard operating software of most RSDs.”
“Before this event I would never countenance using a lidar without a hub height met mast,” said Ioannis Antoniou, Senior Key Expert Advisory Engineer at Siemens Gamesa. “Now we are one step closer to being able to use remote sensing data on its own.”
“To the best of our knowledge, Windcube is the only lidar in the market so far to have achieved full IEC 61400-12-1 ed2 2017 compliance via an independent third party recognized worldwide,” said Peter Spencer, Chief Marketing Officer (CMO) for Leosphere.
“This workshop was a great opportunity for us to share details of the findings and to discuss operating parameters with international organisations for whom the accuracy of wind speed testing is a major requirement. The presentations were very well received, and we’re delighted to have received validation not only from this classification but also positive feedback for the transition to vector averaging from so many significant players.”
1.The vector averaging of the RSD does not modify the application of standards, since the RSD using it is calibrated against a cup, which thus ensures traceability to national standards.

Windcube becomes world’s first lidar device to achieve full IEC 61400-12-1 ED2 2017 compliance with independent third-party classifications
Paris, France 18th June 2018. –Leosphere has announced that Windcube, its ground-based Lidar, has successfully met the full conditions for the IEC 61400-12-1 ed2 2017 standard.
The IEC 61400 12 1, ed. 2  standard sets a scheme to assess the uncertainty of remote sensing devices (RSDs), involving a calibration test for every unit and a classification for every type of instrument. The calibration gauges the accuracy of measurements in the context of prevailing environmental conditions during the test, and the extent to which this calibration may be affected by other environmental conditions on other occasions.
To assess the influence of these changing conditions on the accuracy of the RSD, a sensitivity analysis or classification is needed in which the deviation between the RSD and reference mast measurements is analysed with regard to different environmental variables.
The conditions of the standard require measurements on at least two different units, and one unit at two different sites – in other words, at least three measurements – in order to assess sensitivity to the environmental parameters. In the classification exercise, which was conducted independently by Deutsche WindGuard Consulting GmbH, Windcube achieved all three classifications, meaning it is now fully compliant with the standard.
The testing exercise took into account four significant and independent variables: wind shear, turbulence intensity, wind direction and precipitation. Measurements were taken at five-meter intervals at heights ranging from 40 metres to 135 metres.
Accuracy classes of 2.7 to 4.2 were calculated, but Deutsche WindGuard noted that the actual uncertainty will usually be smaller than these numbers would indicate. For example, for measurements taken at a height of 135m, the resulting standard uncertainty from the classification was between 0.6% and 1.0%.
Deutsche WindGuard also reported that its experience of regularly calibrating Windcube devices at its test station “confirms a high consistency between individual units of this type.”
“Completing the three third-party IEC classifications,” said Peter Spencer, Chief Marketing Officer (CMO) for Leosphere, “marks the final step in the journey of the Windcube towards complete legitimacy for power performance testing in accordance with IEC-12. It closes any remaining debate about whether Windcube Lidar technology is appropriate and adequate for this application. To the best of our knowledge, Windcube is the only Lidar in the market so far to have achieved this classification.”

Press release: Leosphere Presents its Wind Iris Lidar for Turbine Control to OEMs in the Wake of Goldwind’s E-Farm Announcement
Paris, France, 28 November 2017. Leosphere announces a quantum leap in wind turbine ROI with the Wind Iris TC (Turbine Control). This new Lidar sensor, providing real-time characterization of wind up to 200 metres in front of the rotor plane enables turbine manufacturers to make major strides in improving the efficiency of wind energy production both on and offshore.
The Wind Iris TC platform, used in China’s Goldwind’s ground-breaking E-Farm technology, is the output of Leosphere’s Avent Lidar Technology program and the result of years of intensive research and development to deliver the first Lidar matching the reliability and performance requirements to be installed as a component of today’s advanced wind turbines.
“Leosphere has been investing in maturing Lidar-Assisted Control since 2009” said Alexandre Sauvage, CEO of Leosphere. “We have been working closely with some of the world’s leading turbine manufacturers, as well as other key experts in this industry, to enable the entire wind industry to finally harvest the potential of this technology. With the knowledge we have acquired, the solution we have developed and our unique track record as the world’s number one Lidar provider, we can short circuit the development process for any OEM wanting to enable their turbines to see and react to the wind before it reaches the rotor.”
The Wind Iris TC Lidar measures all essential incoming wind conditions, including rotor averaged wind speed, wind direction, shear and turbulence, at multiple distances before it reaches the turbine rotor. This provides the turbine control system with the essential rotor coverage and preview time required to establish and implement appropriate control actions before the wind reaches the rotor with the critical measurement accuracy and precision required to extract maximum benefit from conditions as the wind reaches the rotor plane.
“Our years of research have shown that only the market leading capabilities of the Wind Iris TC delivers the performance to successfully implement an efficiency improvement of this magnitude that works in the real world throughout a turbine’s lifetime and not just in a simple test scenario”, commented Thomas Velociter, Leader of Leosphere’s Avent program. “The industry expects a Lidar that allows a total transformation of the control system and, with it, a new set of rules and design limits, not just the simple replacement of existing sensors. The Wind Iris TC gives the turbine a short look into the future, providing it with all the time it needs to prepare for the wind before it arrives at the rotor plane. ”
In addition, integrating the Lidar into the turbine platform also enables optimized operation of the wind turbine over the entire lifetime of the investment by improving the alignment, gaining additional turbine availability, extending turbine life and reducing maintenance costs. Thus manufacturers can reduce LCOE significantly and improve profitability of both existing and new schemes.
Whether installed as part of turbine construction or as a retrofit as an element in a turbine life-extension project, Lidar assisted turbine control technology has the potential to redefine wind turbine design limits by reducing loads, mitigating extreme events and increasing energy capture. With typical load reductions from 10-15%, operators can use the longest possible turbine blades for a given class, or even upgrade the wind class of a given turbine platform, both of which will lead to significant energy production increases.
The system uses four beams and ten simultaneous measurements at a frequency of 4Hz across the 200m range to capture events several seconds before they reach the rotor plane and track them as they evolve. Thus it provides a robust representation of the wind field in front of the rotor that is vital to ensure reliable control actions under all possible circumstances.

PRESS RELEASE: Leading wind experts claim LiDAR becoming the clear choice for bankable offshore wind measurements, saving millions on costs
London, 18 July 2017. Leading wind measurement experts gathered in London claimed that LiDARs have been replacing met masts to become the sole wind measurement tool used for offshore resource assessment and power curve verification purposes. These experts stated that LiDAR technology had over the years fully proven its ability to provide wind measurements as reliably as met masts. They also claimed that LiDARs are faster, easier and much cheaper to deploy, enabling significant development and operational cost reductions.
At a seminar hosted by Leosphere at the Offshore Wind Conference 2017, top wind measurement experts explained that years of successful LiDAR validation campaigns and strong competitiveness have led industry leaders to choose this technology over met masts for offshore wind feasibility studies as well as power curve verification tests.
“Experience has taught us that the uncertainty levels offered by LiDARs are at least on par with those offered by met masts. Although we still encounter performance misconceptions surrounding LiDAR technology, it is now hopefully a mere question of time before the industry as a whole recognizes this technology, and IEC standards are adapted accordingly,” explained Anders Thoft Marcussen, Head of Measurements at DONG Energy and chairman of the London LiDAR Seminar. In practice, the use of nacelle mounted LiDARs is already frequently required in the turbine supply agreement for power curve verification testing, even if LiDAR measurements are not yet covered by IEC standards.
Met masts cannot compete with LiDARs on cost in the offshore market. On the Beatrice Offshore Wind Farm Ltd (BOWL) project, a 588MW 84 turbine offshore wind farm off the North East coast of Scotland, the wind measurement campaign was carried out without the use of a met mast. BOWL chose instead to install two vertical profiler LiDARs which enabled them to start the measurement campaign much earlier and without the significant costs associated with installing an offshore met mast. After 12 months of LiDAR wind measurement the project had the essential data needed to help achieve financial close on this £2.6 billion offshore project.
For an offshore project developed by RES, the installation of a met mast, estimated at €12 million, was ruled out in favour of a single fixed LiDAR, coupled with two floating LiDARs. The fixed LiDAR, installed on a nearby lighthouse, and the floating LiDARs located at points across the wind farm zone, enabled the company to secure reliable, bankable data adding millions of euros to the project value in addition to the millions in cost savings and the elimination of the health and safety risks associated with large met mast installation.
“LiDARs have become a reliable, robust measurement system that ultimately delivers the high-quality data to minimise uncertainty and risk while maximising value. The prevailing view among experts is that the future of resource assessment is short masts coupled with LiDAR for onshore, and for offshore probably just the LiDAR. Today, LiDARs are commercially ready and already used in major projects around the world. It’s a trend that is going to continue both offshore and onshore, even in complex flow sites,” concluded Alexandre Sauvage, CEO of Leosphere.
About the LiDAR User Experience session: “Sharing LiDAR practices from financing to performance verification”
At the Offshore Wind conference 2017 in London, Leosphere brought its community together, offering a unique opportunity for users to challenge their views and learn about the potential offered by LiDAR technology, quickly becoming a standard in offshore.Major offshore wind energy players have shared their experience on a wide range of applications, from energy yield assessment to contractual power performance testing.

PRESS RELEASE: A Long Range Scanning Windcube in use for Artic climate study
A Leosphere Windcube 100S is currently being operated by KOPRI (Korea Polar Research Institute) for Arctic atmospheric boundary layer (ABL) wind measurement, as required research activity for weather and climate prediction project of KOPRI.
KOPRI is the one and only organization in South Korea which is dedicated to operate research infrastructures at Polar Regions. In January 2016, KOPRI launched the “KPOPS” (Korea Polar Prediction System) project, where the main objectives are to better understand Arctic climate and to improve prediction of weather and climate in mid-latitude regions.
“It is now well known that Arctic is suffering climate change and climate of the Arctic affects mid-latitudes deeply. So we are very eager to understand what’s going on in the Arctic and want to improve climate model to better predict weather/climate in Korea” says Sang-Jong Park, KOPRI senior research scientist in charge of observational study in the KPOPS project.
The KPOPS project also involves Seoul National University (SNU), Pohang University of Science and Technology (POSTECH), Gwangju Institute of Science and Technology (GIST), Florida State University (FSU), and takes place in the Artic Dasan station in Ny-Alesund, Svalbard archipelago, Norway.
In this project, the Windcube 100S is collecting wind data on a continuous basis to understand 3D characteristics of the ABL of the Arctic. The second objective is to study the interaction of the ABL and Arctic clouds to understand their life cycle.
The Leosphere Windcube was chosen for the KPOPS project because of its demonstrated ability to profile the ABL with a good data availability and quality, and for the limited required maintenance, even when deployed outside in very harsh environmental conditions like those observed in Ny-Alesund.
The Windcube 100S is being successfully operated since mid-October at the Arctic Dasan station, not far from another Leosphere Windcube operating since 2013 by the German Alfred Wegener Institute (AWI). The first measurements gathered during the 2016-2017 winter will be compared with the AWI Windcube data.

NOAA buys WINDCUBE Scanning Lidars from Renewable NRG systems
Renewable NRG Systems, a designer and manufacturer of decision support tools for the global renewable energy industry, announced today the recent sale of two WINDCUBE 200S 3D Scanning Doppler Lidars to the National Oceanic and Atmospheric Administration (NOAA).
WINDCUBE 200S Lidars incorporate advanced techniques to measure the wind components on a large scale for short term campaigns or long term operations to reduce wind flow modeling uncertainties, understand physical phenomena such as wakes, and improve wind forecasting. They are able to perform a full 3D mapping of the atmosphere to provide remote measurements of wind speed, direction, turbulence, and boundary layer height.

Improving the energy efficiency of wind turbines: Launch of the ANR SmartEole project on wind turbine control technologies
The SmartEole project has just been launched following the French National Research Agency (ANR) call for projects on the theme “The energy efficiency of processes and systems”. This project is aimed at improving the energy production efficiency and lifespan of wind turbines via the development of innovative control solutions.
One of the major challenges for the development of the wind power sector is reducing the cost of the energy produced. The implementation of advanced wind turbine control systems represents one of the levers to optimize performance and achieve production gains.
Scheduled to last three and a half years, the SmartEole project is being led by PRISME, a laboratory of the University of Orléans, working alongside three research partners, IFP Energies nouvelles (IFPEN), Le Laboratoire de Mécanique de Lille (LML–CNRS //University of Lille 1 // Ecole centrale de Lille // Ecole nationale supérieure d’arts et métiers de Lille) and the Laboratoire d’analyse et d’architecture des systèmes (LAAS-CNRS), along with two industrial partners, Maia Eolis and Avent Lidar Technology.
SmartEole will lead to the development of control techniques designed to improve the operating conditions of wind turbines. The challenge is to integrate sensor systems (particularly Lidar) capable of accurately detecting incoming wind speed, direction and intensity. By measuring incoming wind, it will be possible to implement real-time control strategies to optimize nacelle and blade orientation. By anticipating the optimum orientation of the wind turbine via the measurement of incoming wind, the mechanical constraints placed on the structure (mast and blades) are significantly reduced, thereby decreasing maintenance costs and increasing the lifespan of the structure. SmartEole also aims to underpin this strategy with innovative concepts, making it possible to reduce mechanical fluctuations for shorter characteristic times via an active flow control system
on the blades.
The control technologies developed within the project will thus be deployed on several scales – the blades, the turbines and the wind farm as a whole – and will form the focus of a range of research, from fundamental research conducted at lab scale up to full-scale demonstration in real conditions.
Two types of experimentation are planned:
– full-scale testing on a Maia Eolis wind farm using control strategies developed by IFPEN with Avent Lidar Technology sensors.
– wind tunnel measurements in facilities operated by LML and PRISME laboratories, with validation of control strategies developed by LAAS-CNRS and PRISME.

Two Windcube 100s Scanning Wind Lidars installed for The Norcowe measurement campaign at FINO1
With good support from FINO operator FuE FH Kiel, scientists from CMR this week successfully completed the first installation phase for the offshore boundary layer experiment at FINO1, OBLEX-F1. Two Windcube 100s scanning wind lidars from LeoSphere and a RPG HATPRO microwave temperature profiler are now operational and connected to the FINO1 network, providing online data access, remote monitoring and control of the instruments.
Deployment of the oceanographic instrumentation is planned for the first week of June with the research vessel Håkon Mosby from IMR. In the same timeframe, we will proceed with the second installation phase at FINO1 for the DCF sonic turbulence meters and breaking wave camera system. The meteorological and oceanographic measurements will run in parallel until the fall, when the oceanographic measurement buoys will be recovered. The meteorological measurements for OBLEX-F1 at FINO1 will continue until June 2016.
The FINO1 Measurement campaign, OBLEX-F1
NORCOWE is starting up an extensive offshore measurement campaign at the German research platform FINO1 close to Alpha Ventus wind farm. The campaign will take place from May 2015 to June 2016, and is carried out by CMR and UIB in close cooperation with the other Norcowe partners, FuE-Zentrum FH Kiel, Fraunhofer IWES, RAVE and ForWind. Benny Svardal at Christian Michelsen Research is responsible for the project management.
The key purpose of the campaign is to improve our knowledge of the marine boundary layer stability, air-sea interaction and offshore wake propagation effects. The collected observational data will be used to validate and improve numerical models and tools for i.e. weather forecasting, marine operations, power performance and wind farm layout. Additionally the campaign scope will cover research on motion correction techniques for floating sensor platforms.
In order to provide unique datasets for the study of boundary layer stability in undisturbed offshore conditions, we will perform simultaneous measurements of wind, temperature and humidity profiles in the MABL. By employing microwave radiometer and lidar remote sensing technology, we are able to map the boundary layer conditions continuously up to an altitude of 1000m. To investigate the atmospheric stability around the wind farm, as well as the interaction of the Alpha Ventus wind turbines with the atmosphere and each other, NORCOWE plan to install two scanning lidar systems and a microwave-radiometer on the research platform. This is the first time that such an instrument is installed at on offshore location. Both the Lidar systems and the radiometer are able to perform continuous measurements up to an altitude of 1000 m.
In addition to the meteorological measurements from the FINO 1 platform, and the floating lidar buoy measurements provided by IWES, oceanographic instruments will be deployed near FINO1 for a shorter period. This instrumentation, mounted on bottom frames, submerged buoys, and the autonomous SailBuoy, will monitor wave statistics, surface currents and turbulence in the upper oceanic mixed layer. The collection of these data is crucial for studying air-sea exchange processes, which are known to influence the structure of the vertical wind profile and the atmospheric stability.
The deployed instrumentation will provide a highly versatile data set for investigation of the offshore wind profiles, wind shear and turbulence intensity as a function of atmospheric stability in and around the wind farm. The gathered data opens for the investigation of the structure, extension, dynamics and persistence of single turbine wakes and the near farm wake of Alpha Ventus.

FLiDAR completes fast, cost effective, accurate and safe offshore wind measurements for Mainstream Renewable Power
FLiDAR have completed the onsite wind measurements at the Neart Na Gaoithe offshore wind farm being developed by Mainstream Renewable Power.
Neart Na Gaoithe, a 448MW wind farm located in the North Sea off the East coast of Scotland, has recently been awarded a Contract for Difference (CfD) by the UK government.
The FLiDAR floating LiDAR buoy provided on-site wind measurements and resulted in a considerable development time and cost saving compared to a traditional meteorological mast.
The unit is now decommissioned and undergoing post validation at the ORE Catapult offshore met mast.
Reinhardt Stevens, General Manager of FLiDAR said “We are delighted to have delivered high availability and accurate wind data in such a short time to our client and congratulate Mainstream Renewable Power on being awarded the CfD.”
David Sweenie, Project Manager of Neart na Gaoithe said “Mainstream recognized the innovative approach of FLiDAR from an early stage, bringing accurate wind data at low cost in a short delivery window.
The data provided by FLiDAR has contributed to the great successes of Neart na Gaoithe so far. “ The FLiDAR technology has been developed by 3E, global renewable energy consultancy and software provider, and Offshore & Wind Assistance (OWA), the subsidiary of marine contractor Geosea. The FLiDAR equipment consists of an industry standard Mobilis buoy equipped with a state-of-the-art buoy-adapted LEOSPHERE WINDCUBEv2 LiDAR held in a passive mechanical stabilisation system. It has previously been tested and validated against fixed met masts in the North Sea and in Irish Sea (as part of the UK’s Carbon Trust Offshore Wind Accelerator programme). The performance has been analysed and validated by third parties and has been proven to deliver wind data with accuracy equivalent to standard offshore wind measurements.

Standalone LIDAR measurements now included in the latest revision of the German TR6 WRA guideline
Since September 22nd the latest revision of the German TR6 guideline for Wind Resource Assessment entered into force.
The objective of these Technical Guidelines for Wind Turbines (known since 1998 as FGW Guidelines) is to present measuring methods allowing the determination of reliable and comparable data for the wind power market, based on state-of-the-art technology. The measurement methods described will serve as best practice for Wind Resource Assessment campaigns in Germany.
Remote sensing made its entrance in the latest revision as an authorized site assessment method under two conditions:
– a device verification test, similar to anemometer calibration, should be conducted every two years by a third part
– and the remote sensing device should undertake a classification test, which the WINDCUBE v2 has already successfully passed (report available upon request).
The guideline now requires 12 consecutive months of measurement, with a minimum data availability of 80%. This represents a major breakthrough for remote sensors now officially recognized by industry leaders as bankable and reliable measurement devices for your wind power development projects.
Only available in German today, an English release of the guideline is expected in the coming months. For more information, please consult : http://www.wind-fgw.de/TR.html
