Task 25 has published two journal articles on close to 100% renewable (and inverter-based) power systems. The first article lists challenges and potential mitigation measures, and is linked to the Task 25 special collection of journal articles for Wiley’s WIREs. The second article formulates the first recommendations for study methodologies for future system dominated by wind and solar, and is available as open access.
