Simposio Internacional sobre la Calidad de la Energía Eléctrica - SICEL

Utility restructuring, technology evolution, public environmental policy, and expanding power demand are providing the opportunity for micro-turbines to become important energy resources. In order to investigate the ability of micro-turbine units in distribution systems, new simulation tools are needed. This paper presents a dynamic model for microturbines. The novelty of this paper is the use of the controlsoriented model of a permanent magnet synchronous generator.  Furthermore, a realistic voltage source inverter with current band hysteresis control is included to simulate the micro-turbine system. The micro-turbine model is implemented in simulation software, and proved in grid-connected mode for several loading sequences. The impact of high penetration levels of microturbines plants in a typical distribution feeder is discussed too.
