Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2029.

Abstract

This NSF project aims to develop new optimization methods for operating the electric power grid reliably and economically with a high penetration of inverter-based resources (IBRs). IBRs are rapidly replacing synchronous-generator-based power plants as energy sources. These IBRs introduce new frequency stability challenges because they lack rotational inertia and respond to disturbances differently from synchronous…
