This topic includes news on individual projects, publications and other NWTC activities.

The Wind Plant Optimization and Systems Engineering Newsletter series from the National Renewable Energy Laboratory (NREL) Wind Energy Systems Engineering Initiative highlights current system approaches to the wind energy research, design, engineering, and development. Each quarterly edition provides short overviews of the integrated, interdisciplinary, and holistic work that is happening in this field. The wind industry community increasingly recognizes the need for a systems approach, and this newsletter serves to support stakeholders who engage with this important work.

First Quarter, Fiscal Year 2014 (Edition 2) is available here http://www.nrel.gov/wind/systems_engineering/news.html.

We are happy to announce the release of the new nwtc.nrel.gov website, which replaces much of the old wind.nrel.gov website. The new website is still used for NREL/NWTC’s sharing of software and data with the wind engineering community, but sports a more modern, flexible, and easier-to-navigate interface. The new website also resolves a fundamental complaint with the previous website—that user information had to be entered separately with every download. You can browse the new website without logging in, but most downloads now require registering for an account and logging in with a username and password. While registration is now required for most downloads, the software and data are still free and open source.

Please note that most of the software and data available on the new website are the same as what was available on the old website, but the formatting and organization have changed. We are working to redirect all the old links, but if you find one that doesn’t work, please use the new search feature in the upper left on the new site. In addition to the CAE tools that already exist, a new class of tools has been added as part of the new Wind-Plant Integrated Systems Design and Engineering Model (WISDEM) suite. These new models include design, sizing and cost tools as well as the overarching WISDEM software which integrates them together. Look for a more detailed announcement about the new models in the near future.


Hello everyone,

Registration for the 3rd biannual workshop on wind energy systems engineering is now open! Please register on the workshop website here:
nrel.gov/wind/systems_engine … _2015.html
Note that there is a discounted registration fee before December 15th, 2014.

This year’s workshop features an exciting line-up of speakers on the topic of integrated system analysis and design of wind turbines and plants. The full agenda is can be found here:
nwtc.nrel.gov/system/files/Draf … 102014.pdf . We hope you will join us!

Also, there will be a poster session and we are currently accepting abstracts. Please submit your <250 word abstract and short biography to systems.engineering@nrel.gov .

Please distribute to those who you think may be interested, and please contact me if you have any questions.

Registration is now open for the 4th bi-annual Wind Energy System Engineering Workshop, that will be held in Roskilde Denmark, September 13-15 2017. The event is jointly hosted by the Department of Wind Energy at the Technical University of Denmark (DTU Wind Energy) and the National Renewable Energy Laboratory (NREL). See conferencemanager.dk/SEworkshop2017 to register and for additional details.

           The first workshop in December 2010 was a success in catalyzing interest in this important topic among participants from industry, the national laboratories and academia.  The second and third workshops in January 2013 and 2015, respectively, with more than 100 participants each, demonstrated the significant growth in interest from the research and industry community surrounding systems engineering for wind energy and integrated approaches to wind turbine and plant design.  At this fourth workshop, DTU Wind Energy and NREL will be hosting the workshop in Europe to encourage participation from European wind energy systems engineering practitioners and interested parties.  This year’s theme will be on exposing interactions in the system and exploring how different wind energy stakeholders addressing them in new, integrated and innovative ways. 

September 13-14 - Talks from invited speakers:

           Keynote talks from
                    Anders Bavnhøj Hansen, Energinet
                    Hanne Johansen, Vestas
                    Peter Fuglsang, Siemens Gamesa Renewable Energy

           Sessions on:
                    Challenges and Uncertainty Facing Today’s Wind Energy Systems
                    System Design Methods, Tools and Processes
                    Integrated Design for Wind Energy Systems in Practice

Poster Session - September 13th

           All the speakers are invited, but that does not mean you cannot present your work. We will be hosting a poster session in the evening on the first day. This is a great opportunity to network and showcase your work. All participants are welcome to prepare posters on their work in wind energy system engineering. If you want to present a poster please send a brief abstract to [workshops@windenergy.dtu.dk](mailto:workshops@windenergy.dtu.dk).

Software Tutorials - September 15th

           There are many excellent tools for wind energy system engineering. Tutorials will be provided for many of these tools on the last day. This is an excellent opportunity to get hands on experience and meet with the developers behind these projects. The following tools will be demonstrated:

           FUSED-Wind - DTU/NREL collaboration
           HAWTOpt2 / Topfarm - DTU Wind Energy
           WISDEM - NREL
           Cp-Max - TU Munich

           For more details and registration please see [workshops@windenergy.dtu.dk](mailto:workshops@windenergy.dtu.dk).

Dear All,

The NWTC Information Portal (nwtc.nrel.gov) has crashed and is no longer available. There was already a plan in place to decommission the site and put much of the same content on nrel.gov/wind, but the NWTC Information Portal crashed before the new site could be brought online. The NWTC Information Portal currently redirects to: nrel.gov/wind/nwtc.html. Rest assured that the content from the NWTC Information Portal has been archived. The new site should be online soon, within a few weeks.

In the meantime, please access NREL’s open-source tools from github:
OpenFAST and related pre- and post-processors from github (github.com/OpenFAST).
WISDEM (github.com/WISDEM)
FLORIS (github.com/nrel/floris)
SOWFA (github.com/NREL/SOWFA)
Exawind, including Nalu-Wind and amr-wind (github.com/Exawind)

If there is content from the NWTC Information Portal that you need before the new site is up, please let us know (and be specific).

FYI: This NWTC discussion forum is also in the process of being decommissioned and replaced. I’ve been assured that the 15-year history will be maintained in the new forum. The new forum should come online later this summer.

Best regards,

Dear All,

Related to the previous announcement regarding the decommissioning of the NWTC Information Portal, my public site where I’ve been sharing files has also been taken down. I’ve now transferred these files to a shared read-only directory on Google Drive.

So, for any link on this forum directed to:

the new link is now:
drive.google.com/drive/folders/ … sp=sharing

(the subdirectories and files are unchanged).

Best regards,

Dear All,

The replacement for the old NWTC Information Portal is now available at: nrel.gov/wind/nwtc.html. This is mostly an archive of older software and documentation that is not actively being developed through github.

Best regards,

Dear All,

A new site that will replace this forum is coming soon. The new site will include the existing forum content and users, but will not be based on php. Expect some downtime beginning Friday, January 21, 2022 while we get things ready. More information will be forthcoming.

Best regards,

Dear All,

Welcome to the NREL’s Discourse-Based Wind & Water Forum! This forum is used to support the software and data provided by NREL’s wind and water programs.

This forum replaces the old php-based NWTC forum previously hosted at NWTC - Index page. All content and users from the prior forum have been ported from the old to the new forum, but the new forum supports a more modern format and functionality.

Best regards,
