| Abstract: | An underfrequency load shedding(UFLS) strategy is proposed for an islanded microgrid.The characteristics of different distributed energy resources are summed up and a dynamic microgrid simulation model is developed that is composed of the wind turbine-driven doubly-fed induction generator(DFIG),photovoltaic,fuel cell,microturbine,storage battery and local controller.The frequency control scheme of an islanded microgrid is explored and the relationship between the rate of frequency change,inertia constant an... |
