Contribution of Voltage Support Function to Virtual Inertia Control Performance of Inverter-Based Resource in Frequency Stability
Inertia reduction due to inverter-based resource (IBR) penetration deteriorates power system stability, which can be addressed using virtual inertia (VI) control.There are two types of implementation methods for VI control: grid-following (GFL) and grid-forming (GFM).There is an apparent difference among them for the voltage regulation capability,
