【Abstract】 The general situation of distributed generationis presented. The reduced-order model of fuel cell for stabilityanalysis of a grid-connected fuel-cell power plant, includingthe voltage control and power control circuits, is described. Amicro-scale gas turbine engine involves four parts, i.e., a gasturbine, a permanent-magnet alternator, a three phase bridge ofrectifiers and a DC/AC power inverter. According to thedynamic characteristics and interrelation, a dynamic model ofmicro-scale gas turbine engine suitable to transientcharacteristics analysis and power system simulation isestablished.更多还原
