Abstract
Stability analysis of conventional power systems relies on established modelling practices and tools. Among them, a popular approach exploits the impedances at given buses computed after deriving the power flow solution of the grid typically modelled in the dq-frame. However, in modern grids, this approach is hindered by the presence of elements formulated in the abc-frame, such as inverter-based resources, which make the grid a hybrid system. This paper proposes a novel efficient and versatile tool, directly implemented at simulator level, that allows computing impedances even in these cases.
