An electric vehicle charging and discharging method considering user weight flexible demand response comprises the steps that an electric vehicle user selects an optimization weight; the user considers two options of charging cost and charging speed according to the battery state of an electric vehicle; according to the weight selected by the user, whether rigid demand response or flexible demand response is involved is determined, if the selected charging speed weight is large, the rigid demand response is selected, and otherwise, the flexible demand response is selected; according to the selected demand response mode, an objective function is constructed, an optimal charging control coefficient is obtained, and charging is started. Different demand responses of electric vehicle charging and discharging are considered, rigid and flexible demand responses are analyzed, an objective function is established based on charging and discharging cost, constraint conditions are established in combination with limitation of charging and discharging power, finally, the peak-valley difference of a load curve and TSOS are reduced by 84%, and the variance of the load curve is reduced by nearly 100%.

    一种考虑用户权重柔性需求响应的电动汽车充放电方法,包括电动汽车用户选择优化权重:用户根据电动汽车电池状态考虑充电费用和充电速度两个选项,做出权重选择构建柔性需求响应充放电模型:根据用户选择的权重:确定参加的是刚性需求响应还是柔性需求响应,若选择充电速度权重大,则选择刚性需求响应,反之,则选择柔性需求响应;提出充放电最优策略:根据选择的需求响应模式,构建目标函数,得出最优充电的控制系数,开始充电。本发明考虑电动汽车充放电不同的需求响应,分析刚性、柔性需求响应,基于充放电成本建立目标函数,结合充放电功率的限制建立约束条件,最终得出负荷曲线峰谷差与TSOS降低了84%,负荷曲线方差降低了近100%。
