The invention discloses an electric vehicle cluster control method and system, and the method comprises the steps: obtaining the travel data of an electric vehicle, and building a behavior characteristic model of the electric vehicle according to the travel data of the electric vehicle; calculating an operation domain of the electric vehicle participating in the power grid auxiliary service based on the behavior characteristic model; and controlling the electric vehicle cluster to respond to the power grid change auxiliary service demand according to the operation domains of all the electric vehicles. According to the technical scheme, the operation domain of the electric vehicle is determined by determining the behavior characteristic model of the electric vehicle, the available capacity of the electric vehicle cluster can be determined, the output stability of the electric vehicle cluster can be improved by responding to the power grid change auxiliary service requirement based on the operation domain, unnecessary loss of a power battery can be avoided, and the power utilization rate is improved. And the aging cost of the power battery can be reduced.

    本发明公开了一种电动汽车集群控制方法及系统,方法包括:获取电动汽车出行数据,根据电动汽车出行数据,建立电动汽车的行为特性模型;基于行为特性模型,计算电动汽车参与电网辅助服务的运行域;根据所有电动汽车的运行域,控制电动汽车集群响应电网变化辅助服务需求。本发明所提供的技术方案通过确定电动汽车的行为特性模型确定其运行域,可明确电动汽车集群的可用容量,进一步基于运行域响应电网变化辅助服务需求可提升电动汽车集群的出力稳定性,同时可避免动力电池的非必要损耗,有助于动力电池老化成本的降低。
