Scheduling method and device for electric vehicle charging and discharging stations

The invention provides a scheduling method and device for electric vehicle charging and discharging stations. The method includes obtaining a current power grid load value; judging whether the current power grid load value is greater than or equal to a preset power grid load upper limit value or not; if the current power grid load value is greater than or equal to a preset power grid load upper limit value, outputting discharge signals used for indicating discharge of electric vehicle batteries. Therefore, the electric vehicle charging and discharging stations can charge and discharge the electric vehicle batteries according to the power grid load condition, peak clipping and valley filling for the power grid load are facilitated and power grid scheduling difficulty at load peaks is reduced. 种电动车储换电站的调度方法及装置，所述方法包括：获取当前电网负荷值；判断所述当前电网负荷值是否大于或等于预设电网负荷上限值；如果所述当前电网负荷值大于或等于所述预设电网负荷上限值，则输出用于表征控制所述电动车电池放电的放电信号。实现了电动车储换电站根据电网负荷情况进行充放电，有利于对电网负荷削峰填谷，减轻了电网调解负荷高峰的难度。
