Contribution of synchronous compensators to the stability of inverter-based generation

Abstract

The power system resulting from the energy transition will lack inertia and short circuit strength which affects the stability of inverter-based resources (IBRs) under grid-following control schemes ([1], [2]). Despite the developments in grid-forming control of IBRs, synchronous compensators are being proposed and installed in many power systems to address the aforementioned issues ([3], [4]). This contribution discusses the contribution of synchronous compensators to the converter driven stability of type 3 and 4 wind generators. In addition, their contribution to the damping of inter-area oscillations will be addressed [5].
