Micro-grids with high renewable penetration have low inertia and it leads to frequency stability problems. Virtual inertia emulation provides active power to system during transient time to improve dynamics frequency stability. In this study, derivative technique is used to calculate the derivative of frequency for virtual inertia emulation. Simulations results confirm that frequency dip occurs in case of contingency and virtual inertia control reduces this frequency deviation. It helps to improve overall frequency stability and prevents unnecessary load shedding.
