The invention belongs to the technical field of electric power system operation optimization and control, and particularly relates to a user load directrix-based demand response method considering electric vehicle network access. The method comprises the following steps: step 1, acquiring charging parameters of an electric vehicle, and simulating charging characteristics of the electric vehicle; 2, acquiring parameters of the whole network, and obtaining data such as fixed load and day-ahead predicted new energy output in the system; step 3, carrying out a group of random sampling on the charging characteristics of the electric vehicle, and respectively calculating all load directrixes; step 4, performing error calculation on the calculated group of load directrix, and if the error is smaller than a set threshold value, taking the average value of the group of data as the load directrix; otherwise, returning to the step 3 for recalculation; 5, evaluating the response effect of the user, and determining respon
