The invention relates to a vehicle-station-network multi-level energy management and transaction method based on distributed robust optimization, and the method comprises the steps: firstly constructing a double-layer deterministic model with the maximum interests of a plurality of subjects as a target between a power distribution network operator and a plurality of charging stations aggregated with electric vehicles; then, a double-layer Wasserstein distribution robust model with the purpose of maximizing respective benefits of multiple subjects is constructed between a power distribution network operator and the multiple charging stations aggregated with the electric vehicles; and finally, a dual principle is adopted to convert a double-layer max-min problem into a double-layer max problem, then KKT, the dual principle and a large M method are combined to convert the double-layer max problem into a single-layer mixed integer second-order cone programming model, a solver is utilized to solve, and the effectiveness of the proposed model is proved through example simulation, so that effective management of multi-element subjects in the active power distribution network is realized, new energy is fully consumed, and the power distribution network performance is improved. The EV demand response capability is effectively mined, and the network security is ensured.
