This paper discusses the modeling and dynamic performance of a gas microturbine used as a distributed generator (DG). The model is valid for transient studies and includes speed, temperature, and 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 Simscape Electrical of MATLAB/Simulink. Steady-state and transient performance analyses are carried out for validating the methodology applied and the components used.
