Recommendations on potential standards changes for distributed wind: driving research via IEA Task 41

Aiming towards recommendation of updates to the standards that concern distributed wind systems, this report addresses ‘small’ wind turbines and associated technology, as well as larger turbines not covered by either the small wind or ‘large’ industrial standards. Via previous and ongoing discussions within the International Energy Agency’s Wind Technical Collaboration Program (IEA Wind TCP) and the current task (IEA Task 41), the need for such updates have been identified. Areas of research to support such updates are outlined, based on the joint experiences and interactions between Task 41 members and industry in IEA workshops. Beyond understanding issues with the existing standard, research is needed to document problems and concerns, and justify potential revisions. In the past, targeted research under the IEA Wind TCP produced results for experts to consider when (re-)writing standards, such as the previous (second) revision of the IEC 61400-2 on small wind turbines; here Task 41 also aims to do so. Finally, potential updates are given, as planned for deliverable 1.1 in the (EUDP funded part of the) IEA Task 41 project.
