The invention relates to the technical field of flexible direct-current power transmission, and particularly provides an electric vehicle group aggregation charging and discharging control method and device, and the method comprises the steps: classifying electric vehicles, and determining an energy accumulation boundary and a charging/discharging power boundary corresponding to the types of the electric vehicles; and substituting the energy accumulation boundary and the charging/discharging power boundary corresponding to the type to which the electric vehicle belongs into a pre-constructed aggregation model to perform constraint control on the charging and discharging power of the electric vehicle group. According to the technical scheme provided by the invention, the electric vehicle group aggregation model considering the charge and discharge energy loss is established from the perspective of energy accumulation, and then the charge/discharge power schedulable boundary and the energy accumulation boundary of the electric vehicle group aggregation model are described, so that the calculation and communication burden can be reduced; a corresponding charge and discharge control algorithm may be supported to determine charge and discharge behavior of a single electric vehicle.

    本发明涉及柔性直流输电技术领域,具体提供了一种电动汽车群聚合充放电控制方法及装置,包括:对电动汽车进行归类,并确定电动汽车所属类型对应的能量累积边界和充/放电功率边界;将所述电动汽车所属类型对应的能量累积边界和充/放电功率边界代入预先构建的聚合模型对电动汽车群的充放电功率进行约束控制。本发明提供的技术方案,从能量累积视角建立考虑充放电能损耗的电动汽车群聚合模型,进而刻画电动汽车群聚合模型的充/放电功率可调度边界和能量累积边界,能够减少了计算和通信负担,可支撑相应的充放电控制算法以确定单体电动汽车的充放电行为。
