The replacement of synchronous generators with Inverter-Based Resources (IBRs) has drastically reduced the total rotational inertia of power systems, leading to rapid frequency fluctuations and high Rate of Change of Frequency (RoCoF) during disturbances. This paper investigates advanced Virtual Inertia Emulation (VIE) and frequency support strategies. We present the design of a Virtual Synchronous Generator (VSG) control framework that mimics the kinetic energy release of physical rotors. A comparative performance evaluation is conducted between conventional droop control and self-synchronized VIE strategies. Simulations performed in a modified IEEE 9-bus system demonstrate that the proposed adaptive virtual inertia control improves the frequency nadir by 35% and reduces RoCoF by 42% under severe load contingencies.
