This one is for the power geeks!
As the energy transition proceeds, and grids have to accommodate more and more inverter-based generators like wind and solar systems, how will grid operators maintain system inertia? For that matter…what if we start operating grids without inertia?
One way to manage it is through “grid-forming inverters,” which can generate the necessary signals for conventional grid-following inverters and thus mimic the operation of synchronous generators.
In this episode, we “turn it up to 11” and speak with a researcher who has been exploring these questions at the University of Colorado in Boulder and at the National Renewable Energy Laboratory (NREL), who explains how these resources might work at high penetrations of renewables on power grids, and what kinds of additional research are still needed to transform the grid to one that is friendly to inverter-based resources (or IBRs).
