The invention belongs to the power grid black start method technical field and relates to a DG startup and operation characteristic comprehensive evaluation method. The method includes the following steps that: designing a DG startup and operation characteristic comprehensive evaluation index system; calculating the objective weight of each evaluation index; calculating the subjective weight of each evaluation index; calculating the comprehensive weight of each evaluation index; and calculating the relative nearness degree of each evaluation index. According to the method of the invention, a subjective evaluation method and an objective evaluation method are combined, so that the shortcomings of a single method can be eliminated; DG startup characteristics and DG operation characteristicsare comprehensively evaluated; the role of DG in the black start process of a power grid is rationally utilized; and decision making references can be provided for the reasonable arrangement of the start time sequence of the DG in the black start process and the selection of the primary reference sources of the black start of a micro power grid.
