A grid-forming inverter operating in Virtual Synchronous Machine (VSM) mode emulates the behavior of a synchronous generator by establishing the grid’s reference voltage and frequency. In doing so, it contributes virtual inertia and damping to stabilize frequency and voltage while facilitating power sharing among inverter-based resources.
In the grid-connected inverter, the associated well-known variations can be classified in the unknown changing loads, distribution network uncertainties, and variations on the demanded reactive and active powers of the connected grid.
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
