Item Performance of microturbine generation system in grid perturbation condition(2013) Nayak, S.K.; Gaonkar, D.N.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. © 2013 IEEE.Item Power management of hybrid fuel cell and microturbine based DG system in utility connected mode(Institute of Electrical and Electronics Engineers Inc., 2014) Nayak, S.K.; Gaonkar, D.N.The distributed generation (DG) with fuel cell and microturbine generation (MTG) system is an emerging approach to provide a quality power in the distribution network though the renewable and nonrenewable energy resources. Thus, interconnection of fuel cell MTG based DG system to the distribution network has to withstand several grid issues. This paper presents the hybrid operation of fuel cell and MTG based DG system in utility interconnected mode. The hybrid DG system includes a solid oxide fuel cell (SOFC) and MTG system with DC link based air and fuel flow control strategy to limit their output power. The hybrid SOFC and MTG system are integrated at common at common DC link and is delivered to grid through the power electronics interfacing. The model of hybrid DG system with SOFC and MTG system is presented using Matlab/Simulink environment and it performance has been studied through the simulation. © 2014 IEEE.
