Load-following performance analysis of a microturbine for islanded and grid connected operation

Modeling, simulation and performance analysis of a microturbine (MT) generator (MTG) system is carried out in this paper. The MTG system is consisting of a MT coupled with a synchronous generator. The proposed model incorporates power, speed and voltage controller for maintaining constant speed and voltage under variable loading condition. Modeling and simulation tasks are performed in MATLAB-SIMULINK platform for different loading conditions under isolated and grid connected modes. Performance study of the MTG system is carried out with and without both speed and voltage controller. It is observed from the simulation work that the MTG along with speed and voltage controller performs quite well under load disturbances, thereby, renders its suitability as a viable option for playing a key role as distributed generation for both isolated and grid connected mode of operation.
