The invention discloses a layered and distributed charging and discharging scheduling method and system for an electric power system containing an electric vehicle. The method comprises the following steps: establishing a day-ahead load scheduling model containing the electric vehicle; polymerizing the electric automobile, and introducing into an electric automobile aggregate layer; on the basis of an electric vehicle aggregate layer, generating an aggregate charging and discharging power scheduling instruction according to the upper layer part of the established day-ahead load scheduling model; the lower layer part of the established day-ahead load scheduling model comprises an aggregate layer and a user layer, and the electric vehicle aggregate layer responds to a scheduling instruction and issues a control signal to the user layer, so that distributed solution of charging and discharging scheduling is realized, and a user charging and discharging control result is obtained. The system comprises a model establishment module, an aggregation introduction module, a scheduling instruction generation module and a solving module. According to the method, the defects that aggregation is irreversible and aggregate power solutions are possibly infeasible on individuals in traditional electric vehicle scheduling can be overcome, user privacy can be well protected, and the problem solving and information storage pressure can be effectively relieved.
