Dynamic modeling and control design of microturbine distributed generation systems

Distributed generation draws increasing attention because of the energy shortage and environmental protection considerations. Furthermore, distribution power generation can improve the power system stability and reliability, providing the local power supply economically. Microturbine based power generation has many applications in distributed generation. In this paper, a mathematical model of a microturbine distributed generation system connected to the utility grid is presented. Two back-to-back power converters are connecting the synchronous generator to the grid. The models of microturbine, synchronous generator, and back-to-back power converters are presented and the corresponding control methods are analyzed and designed. The model is developed in MATLAB and simulation results are shown to verify the system performance.
