Modeling and simulation of microturbine generation system for simultaneous grid-connected/islanding operation

Recently, global attention to distributed generation (DG) is increasing due to their potential advantages and merits. Between various sources, microturbines (MTs) as one of the most reliable have a significant contribution in this regard. This paper is presented dynamic modeling of a microturbine generation (MTG) system with a new passive filter topology. MTG configuration is consists of a permanent magnet synchronous generator (PMSG), an AC/DC rectifier, a boost converter, a DC/AC inverter and a remover ripple circuit (RRC) which is operated in isolated and grid-connected mode simultaneously. Using the boost converter and RRC filter is a new and efficient method for microturbine operations. Simulation study is carried out in MATLAB/Simulink and results show fast dynamic and desired performance of proposed structure.
