Abstract

This paper presents the impact of different control settings of the power electronic converter of distributed generation (DG) units on the transient stability of a small power system. A two-bus double circuit power system is used for this purpose. A converter-interfaced DG unit, which is modelled as a three-phase full-bridge IGBT Voltage Source Converter (VSC), and a conventional synchronous generator are connected to the system, and a three-phase balanced fault is applied at one circuit of the system. Three control settings are implemented for the converter-interfaced DG unit during the actual disturbance: automatic disconnection of the unit, staying-connected and delivering constant active power, and staying-connected but with a current limiter. The systems transient stability is assessed by looking at the behavior of the rotor speed of the synchronous machine by using two stability indicators: the maximum rotor speed deviation and the duration of the oscillation.
