The invention discloses an AC/DC (Alternating Current/Direct Current) hybrid modularized microgrid network structure based on hybrid energy storage and a networking method of the structure. The AC/DC hybrid modularized microgrid network structure based on hybrid energy storage is characterized in that a back-to-back converter is connected in parallel to a grid-side converter and a microgrid-side converter by use of a DC bus, the AC side of the grid-side converter is connected to a large power grid orderly through a filter circuit and an isolation transformer, and the three-phase AC output end of the microgrid-side converter serves as an AC bus via an LC filter circuit. The AC/DC hybrid modularized microgrid network structure based on hybrid energy storage has the advantages that the modularized packaging of loads of a plurality of types and distributed power sources of a plurality of types in the AC/DC hybrid microgrid is realized and the modularized microgrid initiatively joins in the dispatching operation of the large power grid as an independently controllable power source/load unit, and moreover, due to reasonable design of the hybrid energy storage system structure and the connection manner thereof, seamless switching of two modes of grid connection and island becomes the natural attribute of the modularized microgrid without complex control algorithm.
