摘　　要：随着直流技术的发展,直流配电网以其电能质量好、传输效率高、方便各类分布式电源接入等优点,成为区域性配电的新选择。文章提出了一种应用于楼宇、适于分布式电源接入的新型直流配电方案,建立了包含风电、光伏、燃料电池等新电源组成的直流配电网结构,在Dig SILENT软件中对分布式电源进行建模,通过仿真对比了并网状态下和非并网状态下储能系统的作用,并分别在系统正常工况下和发生故障时,分析储能系统在直流微电网中的重要影响,结果证明该方案有效可行。With the rapid development of DC technology, the DC power distribution network,which is characterized with good power quality,efficient transmission and easy for various kinds of distributed power supplies to access to the grid,etc,becoming a new choice of regional distribution. This paper proposes a new type of DC distributed power scheme which can be used in buildings and suitable for distributed power supplies to access to the grid. The configuration of distribution network system contains fuel cell,PV,wind power generation and some other distributed generations simulated by using the DIgSILENT/PowerFactory 15.1. Comparing the function of energy storage system between the status of grid connection and disconnection and in normal working condition and failure condition of system, showing that the energy storage system is important to micro DC-Grid. And simulation results demonstrate the effectiveness of proposed scheme.
