Abstract :
This paper proposes a novel converter configuration as a power electronic interface between a high-speed micro-turbine generator and a utility distribution system. The converter system includes a three-level voltage-sourced converter that is connected in a back-to-back configuration to a two-level converter. A space vector modulation based switching strategy is employed to control the converter system. A comprehensive mathematical model is developed for the three- to two-level converter based micro-turbine generator system. The developed model is used to decouple the multi-input multi-output converter controller to multiple single-input single-output subcontrollers. Performance of the overall micro-turbine based generation system is evaluated based on time-domain simulation studies in the PSCAD/EMTDC software environment
