The capability of a grid-forming inverter fundamentally lies in its ability to establish and regulate voltage and frequency within a power system. This core function requires tracking predefined dynamic objectives despite grid disturbances and parameter uncertainties.
This letter proposes that the extreme grid-forming ability of inverters is limited by their dc-side, ac-side, circuit topology dynamics, but not control.
Grid-following inverters have already been widely used for integrating wind and solar energy into power grids due to their simple control structure, their mature PLL technology, and their feature of operating at a determined current (matching the maximum power point or dispatch point of the resource).
In other words, the grid-forming inverter is required to synchronize to an ideal current source and the grid-following inverter to an ideal voltage source, without inner-loop dynamics and grid impedance. The synchronization dynamics are as described by Si and Sv in (a4) and (b4) in Fig. 6.
From Eqs. (3.14) and (3.15), it can be seen that if there is no control delay, that is, Gd (s) = 1, then whether using grid voltage proportional feedforward or full feedforward, the inverter output impedance increases, especially when using grid voltage full feedforward, the inverter output impedance tends to infinity.
When the virtual impedance matches the grid impedance, the system has sufficient stability margin, and the current flowing into the grid will not oscillate. At this time, the impact of the grid-connected inverter on the PCC voltage is minimal.
