The invention discloses a distributed electromobile regulation system and method facing an electric energy service platform. The system is suitable for regulating electromobiles connected to the powerdistribution network, and comprises a coordination module, an evaluation module and a monitoring module; the monitoring module is in communication connection with the electromobiles; the coordinationmodule generates information of the power distribution network according to a load prediction result and characteristics of the power distribution network, and sends the information of the power distribution network to the evaluation module; the evaluation module receives the information, issued by the coordination module, of the power distribution network and charging information reported by themonitoring module, calculates a charging parameter according to the information of the power distribution network and the charging information, and issues the charging parameter to the monitoring module; and the monitoring module collects charging characteristic information of the related electromobiles and charging behavior information of related users, mixes the charging characteristic information with the charging behavior information into the charging information, reports the charging information to the evaluation module, generates a charging priority list on the basis of the charging parameter issued by the evaluation module, and regulates the corresponding electromobiles according to the charging priority list.
