Synchronverters or virtual synchronous generators[1][2] are inverters which mimic synchronous generators (SG)[3] to provide "synthetic inertia" for ancillary services in electric power systems.[4] Inertia is a property of standard synchronous generators associated with the rotating physical mass of the system spinning at a frequency proportional to the electricity being generated. Inertia has implications towards grid stability as work is required to alter the kinetic energy of the spinning physical mass and therefore opposes changes in grid frequency. Inverter-based generation inherently lacks this property as the waveform is being created artificially via power electronics.
