The primary function of a grid-forming inverter in a tidal energy plant connecting to a weak grid is to independently establish and maintain a stable voltage and frequency at the point of connection, enabling the tidal plant to operate reliably and contribute to grid stability even when the grid itself has limited capacity or is prone to voltage and frequency fluctuations. A grid-forming inverter actively creates the AC voltage waveform rather than simply synchronizing with an existing grid voltage. This is crucial in weak grids, which are characterized by low short-circu....
