Zusammenfassung:	The invention belongs to the field of electric power system operation and dispatch and relates to a power-grid double-layer optimized dispatching method considering large-scale electric automobile access. Charging and discharging strategies of electric automobiles are researched from two aspects of a power transmission network and a power distribution network, the optimal charging time of the electric automobiles is determined through the power transmission network, further the optimal charging positions of the electric automobiles in the power distribution network are guided, and the load of the power distribution network is centralized on a certain node of the power transmission network, as shown in figure 1. In the power-grid double-layer optimized dispatching method, the coordination effect of wind power, basic load, a thermal generator set and charging and discharging of the electric automobiles is further considered comprehensively, and effective suggestions are proposed for the charging and discharging time and positions of the electric automobiles by means of a model.
