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.

<p>This paper investigates the mechanisms behind converters driven stability and the stabilizing effect of grid-forming control. The study is carried out by analyzing the linearized state space model of different combinations of controls in a multi-infeed system at various operating points. By conducting a parametric sensitivity study and analyzing the participation factors of key eigenvalues of the linearized models, it is confirmed that grid-forming controls bring a stabilizing effect to the system. Moreover, this paper will demonstrate that this effect varies significantly with the considered grid-forming control: whether a current control loop is used or not significantly impacts stability.</p>

To insure a stable and reliable operation of the existing and future grids, it is important to study the stability of the power electronic based converters' controls which can replace synchronous generation. Most existing studies use a Thévenin equivalent model of the grid to test the grid following controls. The present article demonstrates the limits of these studies. An alternative setup is proposed and is shown to provide more insight into the underlying mechanisms of the grid following control behaviour in weak grids, using a linearized state space model. These insights are exploited to propose further improvements to the control. These improvements are shown to extend the stability of the control while reducing the interactions among converters.
