Abstract

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.
