A review on the suitability of virtual inertia strategies for the next generation of low-inertia power systems

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Modern power grids are increasingly challenged by the lack of inertia caused by the high penetration of renewable energy sources (RES). This low inertia leads to reduced frequency stability and greater vulnerability to disturbances. To address this issue,
