The invention discloses a layered and distributed electric vehicle charging and discharging scheduling method and system based on an electricity price signal. The method comprises the following steps: establishing a day-ahead electric vehicle charging and discharging scheduling model of an electric power system; converting the day-ahead electric vehicle charging and discharging scheduling model of the electric power system into a series of sub-problems to obtain a distributed charging and discharging scheduling mechanism based on price response; the convergence of solving the scheduling problem is improved; and aggregating the electric vehicles, and obtaining a layered and distributed electric vehicle scheduling mechanism. The system comprises a model building module, a model conversion module, an improved solving method module and an aggregation module. The invention provides two types of signals, namely an electricity price signal of system scheduling and a charge and discharge control signal of an aggregate, establishes an electric vehicle layered distributed scheduling method by separating target functions and constraints corresponding to a generator set and an electric vehicle, and forms a scheduling method conforming to a current electricity market construction trend. And a corresponding solving algorithm is provided, so that the convergence is effectively improved, and the operation cost of the power system is reduced.
