Abstract

This research demonstrates the potential contribution of synchronverters with virtual friction to the damping of inter-area oscillations and the enhancement of the transient stability of a power system. Virtual friction creates additional torque acting on the virtual rotor of the synchronverter, which is equivalent to viscous friction being present between this synchronverter and the virtual rotor of another (usually remote) synchronverter or bus bar. This function is realized by creating communication lines between synchronverters in different areas of a power system and expanding the synchronverter algorithm. Our study is based on simulations in PSS/E for an IEEE benchmark two-area network.
