The invention relates to the technical field of new energy electric vehicle charging and discharging, in particular to an electric vehicle emergency supporting capacity characterization and decision-making method and device in a disaster scene, electronic equipment and a storage medium, and the method comprises the steps: constructing an electric vehicle charging and discharging model, and optimizing the electric vehicle charging and discharging model through a normal distribution parameter simulation method; and performing secondary optimization on the electric vehicle charging and discharging model based on the consumption data and the power market output error in the power distribution network system, and inputting the electric vehicle and new energy output parameters into a second optimized electric vehicle charging and discharging model to obtain a final electric vehicle aggregator charging and discharging decision. The method comprises the following steps: performing flexible feasible region accurate modeling by combining battery types and residence time parameters of the electric vehicle in different scenes, constructing a two-stage stochastic optimization model, and measuring and calculating the consumption condition of each new energy system in a power distribution network system. The economical efficiency and the toughness of the power system are improved, and the power imbalance degree of the power distribution network is reduced.
