In this paper the impact of the protection scheme of converter connected (power electronic interfaced) distributed generation (DG) on power system transient stability is investigated. Two simulation setups are used for this purpose. In the first setup, a small/simple test system is used and the converter connected DG is modelled as a practical three-phase full-bridge Voltage Source Converter (VSC). In the latter, a medium size power system is considered and the converter connected DG is represented as simple PQ-source. In both setups, two possible protection schemes of converter connected DG are studied. The first one disconnects the DG from the power network during a fault while the second one keeps the DG connected.

Nyckelord: converter connected distributed generation (DG), DG protection scheme, power system transient stability
