This paper discusses the modeling and the dynamic performance of a gas microturbine used as a distributed generator (DG). The model is valid for transient studies and includes a speed control, a temperature control and an acceleration or fuel control. The microturbine system consists of a gas microturbine engine, a permanent magnet synchronous generator (PMSG), a three-phase rectifier bridge and a three-phase voltage source inverter (VSI) for connecting to the electric distribution grid.  The detailed modeling approach is accomplished by using SimPowersSystems of MATLAB/Simulink. Steady-state and transient performance analysis are carried out for validating the methodology applied and components used.
