The microgrid contains a large number of inverter based distributed generators, whose operation control and fault characteristics are different from that of traditional synchronous generators. The inverter control mode is analyzed. The simulation model of different operation control modes (grid-connected operation and islanding operation) in the microgrid is established on the DIgSILENT simulation software. The fault characteristics of both side and distribution line side, and the influence of the fault protection under different operation control modes are analyzed and compared, which provides the basis for the protection strategy of the distributed power microgrid.
