Performance of microturbine generation system in grid perturbation condition

The distributed generation (DG) with microturbine generation (MTG) system is an emerging approach for providing a quality power in the distribution network. Thus, interconnection of MTG system into the distribution network has to withstand several grid issues, such as, balanced voltage dip, unbalanced voltage, voltage swell and many more. This paper presents the performance of MTG system in utility interconnected mode along with consideration of grid perturbation. The developed model of MTG system includes a microturbine as a prime mover, permanent magnet synchronous generator (PMSG) and power electronics interfacing circuit for grid interface. The performance of MTG system is analyzed in grid connected mode along with grid disturbances developed in Matlab/Simulink environment. The programmable voltage source is used to inject the grid disturbance.
