The invention relates to an electric vehicle ordered charging and discharging control method based on a Lagrange distributed algorithm, and belongs to the technical field of new energy. The method comprises the following steps: S1, establishing ordered charging and discharging boundary conditions of an electric vehicle cluster; S2, establishing a power grid side and user side optimization objective function; S3, establishing a scheduling constraint condition of the electric vehicle cluster; S4, continuously updating the Lagrange multiplier to obtain an optimal solution; and S5, achieving orderly charging and discharging scheduling of the regional electric vehicle cluster. According to the strategy, by adjusting the charging and discharging time periods of the electric vehicle cluster, the electric vehicles can be dispatched to achieve peak load shifting, and the electric vehicles obtain reasonable benefits. The control strategy provided by the invention can ensure that the driving demand of an electric vehicle user is not influenced while the electric vehicle participates in the V2G, and the popularization of the V2G technology is facilitated.

    本发明涉及基于拉格朗日分布式算法的电动汽车有序充放电控制方法,属于新能源技术领域。该方法包括以下步骤:S1:建立电动汽车集群有序充放电边界条件;S2:建立电网侧及用户侧优化目标函数;S3:建立电动汽车集群调度约束条件;S4:通过不断更新拉格朗日乘子,获得最优解;S5:实现区域电动汽车集群有序充放电调度。本发明所提策略通过调整电动汽车集群的充放电时段,既能调度电动汽车实现削峰填谷,又可确保电动汽车获取合理收益。本发明提出的控制策略可确保电动汽车在参与V2G的同时,不影响电动汽车用户的行驶需求,有利于V2G技术的推广。
