N2 - Virtual friction (VF) is a technique for stabilizing a grid comprising virtual synchronous machines (VSMs). The idea is to apply a torque to the virtual rotor of each VSM, proportional to the deviation of the rotor frequency from the center of inertia (COI) frequency of the grid. VF can be used to decouple frequency damping from frequency support. Theoretical stability results exist for a well known simplified grid model, the network reduced power system model. These show that under certain conditions, VF can stabilize a grid of VSMs. We investigate the region of attraction (ROA) of the stable equilibrium point of such a grid employing frequency droop and VF and show that VF can make such a system more robust to disturbances and increases the ROA.
