Intelligent community electric automobile ordered charging system and method

The invention discloses an intelligent community electric automobile ordered charging system and method, comprising: performing distributed data acquisition on a plurality of charging pile terminals; generating load prediction data based on historic data generated by collected data through a load prediction algorithm; comparing generated load prediction data with real load data to form a contrast chart between the load prediction data and the real load data; performing layered scheduling with peak load shifting as a target, and setting the optimal object of a model, wherein during optimal computation, the objective function of the model levels a load curve in order to make the electricity purchasing cost of a charging station lowest; and after obtaining the charging power of a single charging station in each period, issuing an instruction to the charging station, the charging station receiving the instruction of an upper level to guide community ordered charging. The intelligent community electric automobile ordered charging system and method guarantee area electricity safety and stability, and are of important strategic significance in electric power system stability and safety, and economic operation.
