Regarding the intermittent nature of wind and photovoltaic resources, an AC-linked micro grid scheme based on wind/PV/hydrogen production and hybrid energy conversion system is proposed in this paper. An overall control strategy is designed to coordinate power flows among the different energy sources and storage units. The models of hybrid energy system and coordinated control strategy are verified by electromagnetic transient simulation using local weather data and load demand, which is conducive to operate wind power and photovoltaic efficiently.
