IEA Standards Virtual Meeting
April 13, 2021
This virtual meeting focused on IEC standards and how to identify and jointly conduct research that will be the technical backstop used by future standards-making experts. The National Renewable Energy Laboratory is leading one effort to improve the quality of aeroelastic modeling efforts and find new methods to validate these aeroelastic models with loads measurements. There is a general preference to develop aeroelastic models instead of using the Simplified Loads Models specified in IEC 61400-2. Further refinement of research challenges for IEC 61400-2 were documented in the draft “Recommendations on potential standards for distributed wind driving research via IEA Task 41.”
Winter 2021 Virtual Meeting
February 9, 10, and 18, 2021
Task 41 has switched from a Fall/Spring to a Summer/Winter task meeting schedule. This change was initiated with the February 2021 virtual task meeting. Task 41 members and guests attended three sessions: Cost Modeling and University Research Collaboration (Session 1, February 9), Distributed Wind in Evolving Electricity Systems (Session 2, February 10), and Wind Resource Assessment and Obstacle Monitoring (Session 3, February 18).
More than 30 experts participated from 12 countries. Guests included Task 26 (Cost of Wind Energy) to discuss cost modeling.
Session 2 was devoted to understanding definitions such as hybrid power plant and hybrid power system, highlighting ongoing work in Denmark and the United States, and identifying synergistic activities such as blackstart studies, development of distributed wind turbine models, and dynamic models. Google Jamboard was used to capture input on several topic areas.
Session 3 focused on the challenges of understanding distributed wind resources and included discussions of:
- The U.S. Department of Energy-funded Tools Assessing Performance (TAP) project, whose objective is site-specific understanding of obstacle influence on distributed wind turbine performance
- Austrian measurement results for building-mounted small wind turbine assessment
- Danish approaches to resource assessment and terrain modeling based on the Fence experiment, using LiDAR to understand impacts of wind blockages.
New University Research Collaboration on Distributed Wind Technologies
November 24-26, 2020
Under the auspices of the International Energy Agency (IEA) Wind Technology Collaboration Programme (TCP) Task 41 – Enabling Wind to Contribute to a Distributed Energy Future, members are launching a pilot project to facilitate global distributed wind research. This effort is open to participants with wind turbine design research expertise. A key element to enable the wider use of distributed wind energy is continuing to lower its life cycle cost. The distributed wind community is looking for opportunities to not only down-scale large wind turbine design that may be appropriate for distributed wind turbines but also to up-scale small wind turbine design with a goal of matching the pace of cost reductions seen in other renewable energy technologies.
We are aware of several leading university professors and graduate students currently researching distributed wind turbine designs and features. We are hoping to expand the number of technical papers and journal articles pertaining to distributed wind turbine design, laying the groundwork for a better understanding of future industry-wide cost reduction opportunities. In today’s virtual environment, there are new opportunities to collaborate, share research results, and build international academic rapport.
We are planning virtual meetings in the 2020-21 academic year to discuss distributed wind research needs identified by the distributed wind industry. It is hoped that will allow enough time for spring 2021 students to identify capstone, scoping, and trade-off studies to be conducted. In June 2021, IEA Wind TCP Task 41 will orchestrate a virtual symposium so that all students can share their results. Industry experts may provide verbal feedback, if requested.
Our goals are to:
- Begin to build global collaborative research targeted at expanding the volume of distributed wind research results.
- Build a platform for more students to engage their minds in distributed wind technologies and produce capstone projects, technical papers, journal articles, and theses highlighting research results that are important to securing a cleaner energy future that is applicable around the globe.
- Provide an opportunity for a global community to present research findings through an annual virtual symposium.
- Share relevant research topics for distributed wind energy development.
- Facilitate feedback from industry and Task 41 experts on research findings.
Fall 2020 Virtual Meeting
October 20-22, 2020
Task 41 members held three 2-hour meetings over October 20, 21, and 22, 2020 to discuss distributed wind research collaboration opportunities with a focus on grid integration, hybrid systems, downscaling and innovation, and specific country research activities. Task members from Taiwan Institute of Economic Research, Inner Mongolia University of Technology, Technical University of Denmark, and the National Renewable Energy Laboratory presented their current research activities. Participants shared great dialog and ideas. Task 41 plans to meet again virtually in February 2021.
