    Abstract: AC / DC hybrid distribution network is a development trend in the future because it has advantages of both AC distribution network and DC distribution network. Introduction was made to the structure and operation characteristics of AC/DC hybrid distribution network in Suzhou industrial park.Combined with the actual grid structure, the operation principle and the operation mode etc features of AC/DC hybrid distribution network, the coordinated control methods of AC/DC hybrid distribution network in the industrial park were given under three conditions, including normal operation, failure condition and grid-connected/islanded transition.The proposed control strategy is beneficial to improve power supply capacity, to raise power supply reliability and to enhance power quality, which realizes multi-point synchronization and grid-connected/islanded flexible transition and achieves rapid fault isolation and self-healing, with very strong generalization performance.
    Key words: AC/DC hybrid distribution network; grid structure; control method; grid-connected/islanded transition
