This paper pointed out that microgrid, an important part in consisting of intelligent grid, was an effective form to realize active power distribution in intelligent grid, giving the structural schematic diagram of the typical topology. Analysis was made to its system con- figuration and operation characteristics, the control theory of intelligent microgrid summarized and discussed to divide the control strategy into grid-following and grid-forming control two categories, each of which included interactive and non interactive control thinking with clear definition and determinant standard. This paper raised the microgrid control strategy in the future. Key words: int
