The invention provides an electric vehicle charging and discharging strategy generation method in a V2G mode, and relates to the technical field of V2G. The method comprises the following steps: S1, taking a single electric vehicle as an object, on the basis of meeting the charging and discharging requirements of the electric vehicle, considering the charging and discharging price so as to enable the economy of the single electric vehicle to be optimal, and generating the charging and discharging power of each electric vehicle in each scheduling period; s2, all the electric vehicles in the transformer area serve as objects, the charging and discharging power, generated in the S1, of each electric vehicle in each dispatching time period is verified and corrected, the charging and discharging power finally executed by all the electric vehicles meets the transformer area charging and discharging capacity constraint, and the corrected charging and discharging power of each electric vehicle in each dispatching time period is obtained; and replacing the charging and discharging power generated in S1 with the corrected charging and discharging power. According to the method, the charging and discharging power of the electric vehicle can meet the charging and discharging capacity constraint of the transformer area, the charging and discharging requirements of the electric vehicle are met, and the charging and discharging economy is improved.
本发明提供一种V2G模式下电动汽车充放电策略生成方法,涉及V2G技术领域。方法包括:S1:以单辆电动汽车为对象,在满足电动汽车充放电需求的基础上,考虑充放电价格以使单辆电动汽车的经济性最优,生成各电动汽车在各调度时段的充放电功率;S2:以台区所有电动汽车为对象,对S1生成的各电动汽车在各调度时段的充放电功率进行校验修正,使所有电动汽车最终执行的充放电功率满足台区充放电容量约束,得到各电动汽车在各调度时段修正后的充放电功率,并使修正后的充放电功率替换S1生成的充放电功率。方法能够使电动汽车充放电功率满足台区充放电容量约束,同时满足电动汽车的充放电需求、提高充放电的经济性。
