The invention discloses a cooperative protection matching scheme for an AC/DC hybrid micro-grid. The AC/DC hybrid micro-grid comprises an AC micro-grid, a DC micro-grid and a bidirectional interconnection converter connected with the AC micro-grid and the DC micro-grid, wherein overcurrent protection P1 is adopted by the AC micro-grid; maximum fault current and time ratio-based protection P2 is adopted by a DC line in the DC micro-grid; and a DC voltage change ratio-based protection P3 is adopted by a DC distributed power supply. The cooperative matching relationship of the protection scheme is as follows: when a DC system is broken, the P2 and the P3 act at the moment when a fault occurs, if the P2 or the P3 refuses to move, the P1 acts after a delay for time T1 and a DC fault is cut off; and when an AC system is broken, the P1 acts at the moment when the fault occurs, if the P2 refuses to move, the P3 acts after a delay for time T2, an AC fault is cut off by backup protection of the P1 and the P2 does not act. Compared with the prior art, the cooperative protection matching scheme has the advantages that the action sequence problem of AC side protection and DC side protection can be taken into account, and the rapidity is good and the reliability is high when the fault occurs.
