Minutes
1. Introduction
• David Schlipf starts the meeting with a round call to all AB members in the line at 4:03 pm.
2. State of workshop proposal #1 (floating lidar)
• Julia Gottschall summarizes the state of workshop (WS) proposal #1: ORE Catapult is confirmed
as host. A planning team has been formed (Julia Gottschall, Jonathan Huges, David Schlipf, Ines
Würth and Detlef Stein). Planning telco is scheduled before Christmas to decide on the date and
other issues. Julia thinks that the workshop can be held in February 2016.
3. Presentation of workshop proposal #3 + discussion (rearranged order)
• Since Davide Trabucchi is no longer in the line, Peter Clive presents workshop proposal #3 on
“Wake measurements with lidars” as stated in the Google Docs document.
• David Schlipf raises the question to the AB: How can we address both groups of the people
(First and Second part)? Peter Clive comments: There are a lot of stakeholders to this topic and
there is a need to have a forum to get everybody on the same page and make sure that nobody
is unaware of measurements or opportunities that exist and may serve their objectives.
• Andrew Clifton: Would be very useful and helpful to have such a WS, since wake steering is an
upcoming topic. A roadmap or similar outcome that shows the path from measurements to
model validation would be very useful. Hence, not only Lidar people but also modeling people
should attend. Nicolai Gayle Nygaard: Good idea. Uncertainties should be considered, too.
• No further comments from the AB. David points out to use the Google Docs document for
further questions and comments. Since the feedback from the AB is all positive, since there are
no objections, and since David Schlipf thinks that the proposal is excellent and timely, Davide
and Peter are nominated by David Schlipf to work out the workshop. Peter Clive accepts.
4. State of workshop proposal #2 (lidar-assisted control) (rearranged order)
• Eric Simley summarizes the state of workshop proposal #2: Lidar companies have been
contacted to see if they are able to attend - one confirmed and another is not sure yet. ACC
organizers sound promising to arrange a meeting room.
• Eric Simley asks which day would be the best. Before (Tuesday) or after (Saturday) the
conference (Wed-Fri), or on last day (Friday). Monday (July 4th) is a Holiday in the US. Dhiraj
Arora asks if there is enough material for a 2-day-workshop. Eric answers that this has not been
figured out yet, but it certainly could be stretched to two days, but also focused on one day.
Andrew Clifton adds that one day is probably more popular to the people, than stretching it out
to Saturday and is enough to get people committed. Dhiraj Arora thinks that before the
conference would probably be the better choice, besides the US-Holiday issue. It is agreed on
Tuesday, or possibly Friday, if the Wind Energy sessions are all on the first two conference days.
5. Workshop strategy + discussion
• David Schlipf explains the current workshop strategy: So far this procedure was more based on
invitations. There is no workshop proposal yet for power performance before late 2016. Idea
was to have all workshops before the general meeting in November 2016. How should we
proceed with this issue? Reach out to all participants or just have three workshops (1. WS in
February, 2. WS in July, 3. WS October, and General Meeting in November)?
• Mike Courtney points out that Rozenn Wagner would be very happy to hold a WS around
nacelle lidar power performance and loads in November 2016 or in 2017 (aligned with the
UniTTe project). Instead a more general ground based power performance could be held in the
first year.
• Andrew Clifton’s workshop is not working for power performance.
• David responds that the idea was to have a workshop regarding the new standard around
EWEA (end of Sept. 2016, Hamburg) since it is more industry related. David asks whether DNV
GL is able to provide a WS proposal as indicated by Detlef Stein. Luke Simmons answers: Not
yet, but maybe by the next meeting. Mike asks: What is the point on having a WS on something
just published as a standard? Peter says that there is a lot happening on this topic and already a
lot of experience has been gathered, which might be worth on summarizing and being brought
together on such a WS. Mike says that we have already done this in the first phase. Ioannis
Antoniou asks what is the spirit of the IEA task? Andrew Clifton answers: What we think is
appropriate can be done.
• David summarizes: We should see, if DNV GL is able to propose a WS or someone from the
participants. It is probably also fine, if we don’t have a WS on power performance in the first
year.
6. Presentation of workshop proposal #4 + discussion
• Andrew Clifton presents the idea to read and revise the Ground Based RP document during a
one-day WS to share experiences. End goal after three month: revised documents.
• Mike Courtney supports the idea of revising the document and points out that similar
documents from Measnet and DNV will be published soon and should be compared at the WS.
Andrew is also thinking on replacing the WS with a more living document (something like a
FAQ). Peter Clive says that it is important not to lose user friendliness. Andrew asks whether he
should take further action on how to avoid the WS? David agrees on that and suggests to try
the FAQ version.
• Mike asks what the purpose of the General Meeting (GM) is. David answers that it is the
presentation of the results from the WS and forum for general discussion, similar to the general
meetings in the first phase. Mike asks if a WS could be held in connection with the GM. David
says that this is absolutely possible and that we should keep this in mind.
7. Presentation of workshop proposal #5 + discussion
• Ameya Sathe will leave DTU and has to withdraw his proposal for the time being.
8. AB meeting strategy
• David Schlipf presents the original plan, which was to have only one physical meeting at the GM
and another one to prepare the GM. David asks: Would you mind having a monthly AB
conference call. Andrew Clifton asks why this is useful. David responds that a fixed, monthly
date would help reduce the agenda and have more time for discussions. Andrew supports this
and asks to have the agenda a couple of days in advance. Mike supports to have it more
regularly, since they are well organized and efficient and it is nice to know that they end after
one hour. Nobody disagrees.
• David will organize an AB conference call every second Tuesday of the month.
9. General comments of the AB to the OA
• No general comments from the AB to the OA.
