摘　　要：本文较为全面地介绍了主动配电网的发展现状和典型应用。针对目前微网仅能单独运行,不能进行网间互动进而发挥分布式电源优势的现状,通过引入直流母线,简化了微网的网间并网,使联合运行成为可能,提出对现有主干配电网具有良好兼容性的主动重组配电网和具有地区性划分特色的配电域概念。通过发挥主动重组配电网的灵活拓扑优势,提高了配电网对分布式电源的消纳能力和运行稳定性,并利用仿真进行了可行性验证和稳定性论证。仿真表明主动重组配电网原理可行,能够切实提高供电稳定性。The development and typical applications of active distribution network （ADN）at present are introduced com- prehensively. Aiming at the problem that micro grids can only run separately and thus cannot function interactively to further bring the advantages of distributed energy resources （DER） into full play, direct current bus is added to simpli- fy the connections between micro grids, which makes a combined operation possible. Moreover, an active recombinant distribution network （ARDN） with the concept of distribution domain, which has a good compatibility to backbones, is proposed. By taking the advantages of ARDN＇ s flexible topology, the consumptive ability of distribution network to DER and the operational stability are improved. Simulations are used to verify the feasibility and stability, showing that ARDN is feasible in principle and it can effectively improve the stability of power supply.
