Do you know the difference between Virtual Inertia and Fast Frequency Response? (pv-magazine-australia.com)
Virtual inertia is a fundamentally different mechanism to fast frequency response (FFR). (pv-magazine-australia.com)
The internal frequency/speed of the grid forming inverter doesn't change instantaneously when the grid frequency changes, just like a spinning mass, it takes time to speed up or slow down - it has inertia (which is settable unlike a physical mass). (pv-magazine-australia.com)
Synchronous machines provide inertia when the grid frequency is higher or lower than the frequency/speed of its spinning mass. (pv-magazine-australia.com)
The frequency will fall or rise much quicker if there is less inertia in the system, making this technology and virtual inertia as a service more and more critical moving forward. (pv-magazine-australia.com)
