The invention discloses a pressure test-based method for evaluating the influence of a distributed power supply on a power grid enterprise. The method comprises the following steps of S1, constructinga cost income framework of a power grid enterprise; S2, constructing a cost income model of the power grid enterprise according to the step S1; S3, setting a pressure factor of the distributed powersupply; S4,setting a pressure-bearing variable of the power grid enterprise; S5, constructing a revenue model of the power grid enterprise related to a distributed power factor; S6, giving a reference; S7, calculating the revenue reference value of the power grid enterprise; S8, calculating the revenue maximum value and the revenue minimum value of the power grid enterprise; S9, calculating the maximum value and the minimum value of the revenue change of the power grid enterprise; S10, obtaining the relation between the change of the consumption and storage ratio of the new energy and the revenue change of the power grid enterprise. According to the invention, the power grid enterprise can effectively handle with uncertain conditions, the randomness information and the unknown informationencountered in the development process of the distributed power supply. Meanwhile, the power grid enterprise can comprehensively consider the effective connection between supply and demand resource coordination and source network coordination. The continuous health development of the power grid is promoted.
