AC and DC distribution network with multiple distributed generations is an architectural feature of smart distribution grid in the future. Firstly, basic framework of AC and DC distribution network containing two regions is established. Photovoltaic generation system, direct drive turbines, double-fed wind turbine and the energy storage device are connected to the distribution network according to the capacity and characteristics of various distributed generations. Secondly, the mathematical model and several typical control strategies of AC/DC interface converter are analyzed in detail as well. Finally, the real-time simulation experiments of feeder lines balancing, uninterruptable power supply and energy dispatch based on the above AC and DC distribution network are carried out by using the diversity of converter control strategy and operation mode. Simulation results verify the technology advantages of the distribution network system architecture in terms of receiving various distributed generations.
