WebA solution towards improving frequency stability and performance in a grid with numerous low inertia DGs/MGs is to fortify the system with virtual inertia. A virtual inertia (VI) system can be established by using an ESS together with a power electronics converter and a proper control algorithm to emulate the required inertia. A schematic of VI ... WebApr 7, 2024 · That is the primary difference between the two – virtual inertia is inherent due to the physics of two interconnected voltage sources whereas FFR will always have a small delay and is reliant on measurement. Why is this important? It depends on how much trouble the grid can get into in that 10 to 100 millisecond delay.
