Grid-Forming Inverter
Also known as: GFM
Inverter capable of establishing grid voltage and frequency autonomously, providing synthetic inertia in low-inertia grids.
A grid-forming inverter can establish a grid voltage and frequency reference autonomously, unlike grid-following inverters which require an existing grid waveform to inject power. Grid-forming capability enables BESS to provide synthetic inertia, fast frequency response, and black-start services — replacing some of what synchronous generators historically provided.
