“…In [184], reactive power synchronisation was proposed, fitted with a saturation trigger ability for the voltage controller's anti-wind, and facilitated a low-voltage ride-through using reactive power sags, while current saturation was used for current protection. In [185] a current limitation and post-fault synchronisation stability method was proposed, using the direct voltage control of a lead-lag filter, based droop-controlled GFM, to operate under balanced and unbalanced grid conditions and a current-control loop, whose threshold was activated at the inception of a fault to limit the current and ensure that post-fault synchronisation was guaranteed.…”

Changes are being implemented in the electrical power grid to accommodate the increased penetration of renewable energy sources interfaced with grid-connected inverters. The grid-forming (GFM) control paradigm of inverters in active power grids has emerged as a technique through which to tackle the effects of the diminishing dominance of synchronous generators (SGs) and is preferred to the grid-following (GFL) control for providing system control and stability in converter-dominated grids. Therefore, the development of the GFM control is important as the grid advances towards 100% inverter-based grids. In this paper, therefore, we aim to review the changing grid scenario; the behaviour of grid-connected inverter control paradigms and major GFM inverter controls, including their modifications to tackle low inertia, reduced power quality, fault-ride through capability, and reduced stability; and the state-of-the-art GFM models that are pushing the universality of GFM inverter control.

“…LVRT capability is generally evaluated for PV systems in the laboratory via LVRT test units [ 11 ]. In grid integrated renewable energy resources, LVRT capability is evaluated to keep converter connected with the grid during temporary fault as well as for transient stability and smooth resynchronisation when fault is cleared [ 14 ].…”

“…Multiple solutions have been proposed to generate the current references under the GFM control scheme such as the conventional dual loop, the virtual impedance or the use of a Quasi-Static Electrical Model (QSEM) (also referred to as the virtual admittance) with the use of the QSEM proving to be the most stable solution 11,12 . Moreover, recent works have shown that it is possible for GFM controls to handle large disturbances events without requiring a current loop 13 . Therefore, investigating the necessity and the impact of the current control on GFM schemes becomes a valid question, which, to the knowledge of the authors, hasn't been sufficiently addressed in the literature.…”

The increasing penetration of power-electronics interfaced resources brings new challenges regarding the small-signal stability of power systems. To address this issue, grid-forming controlled converters have emerged as an alternative to their conventional grid-following counterparts. This paper investigates the mechanisms behind converters driven stability and quantifies the stabilizing effect of grid-forming controls. The linearized state space model of different combinations of control strategies is analyzed in a multi-infeed system considering various operating points. Through a parametric sensitivity study and an examination of the participation factors of key eigenvalues of the linearized models, it is confirmed that grid-forming controls contribute to system stabilization. Moreover, this paper demonstrates that this stabilizing effect varies significantly depending on the specific grid-forming control implemented: whether a current control loop is used or not, notably impacts stability.
