It's pretty easy to get inverters attached to a battery to act like "virtual inertia", in fact this kind of service to the grid is an area where they massively outcompete traditional turbines (providing far better frequency stability for lower cost). This concern is a complete non-issue if you have even a small fraction of the storage that a renewable grid needs.
- rocqua 4y agoThat works for stabilizing power levels. It doesn't do much for stabilizing the frequency of the grid.
- rcxdude 4y agoIt does both (while there's still spinning generators on the grid, those are exactly the same thing because of how the generators work. When there aren't any on the grid, they are in principle seperate, but the inverters will still use the frequency as a signalling mechanism, since it's a very robust means of controlling a system as large and complex as a grid).
