Virtual Synchronous Machine

VSM. Equipment that includes a DC/AC converter controlled to mimic a conventional synchronous machine.

virtual synchronous machine (VSM) (p15)

A virtual synchronous machine is a piece of equipment that includes a DC/AC power electronic converter (PEC) controlled to mimic and, in some cases, to surpass the dynamics and behavior of a conventional synchronous machine (SM) through the inherent synchronization mechanism of SM.

virtual damping (p15)

The damping effect that is implemented through a control function.

virtual impedance (p15)

The impedance that is implemented through a control function.

virtual inertia (p15)

The inertia that is implemented through a control function to emulate the physical inertia of an SM
