udPerformance Evaluation of Fuel Cell and Microturbine as udDistributed Generators in a Microgrid ud

摘要

This paper presents dynamic models of distributed generators (DG) and investigates uddynamic behaviour of the DG units within a microgrid system. The DG units include micro udturbine, fuel cell and the electronically interfaced sources. The voltage source converter is udadopted as the electronic interface which is equipped with its controller to maintain udstability of the microgrid during small signal dynamics. This paper also introduces power udmanagement strategies and implements the DG load sharing concept to maintain the udmicrogrid operation in standalone, grid-connected and islanding modes of operation. The udresults demonstrate the operation and performance of the microturbine and SOFC as uddistributed generators in a microgrid. ud udKeywords: Microgrid, Distributed Generation, Microturbine, Fuel Cell
