Wind Energy, Volume 29, Issue 11, November 2026.ABSTRACT Offshore wind power, like other variable renewable electricity sources, requires variation management strategies (VMS) to address demand–supply imbalances in the electricity system. From a functional perspective, VMS that can absorb excess electricity are particularly well suited to wind power, which exhibits strong temporal variability.
