Multi Time ScaleModeling fortheControl Design of a Grid Connected Micro TurbineGenerator by Power Electronic Converters

Inthispaperanequivalent continuous modelof powerelectronic converters isusedtodesign adynamic modelof anentire gasmicroturbine generation system. Itisshownthatthe obtained modelisinteresting foranalyzing thedynamic behavior oftheentire system andfordesigning thecontrol strategy ofAC andDC electrical quantities. Inordertocontrol thepowerflows a dedicated modelisdesigned todescribe energyvariations in storage elements (inertia, DC capacitor bus)andvarious losses. Thenwe demonstrate thatthismodelissufficient todesign the control system oftheentire powergeneration system, meanwhile theturbine, thepermanent synchronous generator andthegrid connected converter. Theproposed global modelissimulated with thehelpofMatlab-Simulink7m,
