| 大力发展电动汽车产业是作为缓解化石能源危机的新举措，而其无序充电模式将加剧负荷峰谷差，影响电力系统安全稳定运行。针对上述问题，提出考虑用户充电推移时间的电动汽车有序充放电策略，将剩余电量与相邻时段充放电限制作为约束，建立以负荷均方差与用户费用最小的多目标优化模型，采用带精英策略的快速非支配排序遗传算法(non-dominated sorting genetic algorithm-II, NSGA-II)对上述模型求解，最后得出最优折中解。算例表明，对于不同约束条件下模型都可得出充电最优推移时间，在限制用户充电时间内能够减小负荷峰谷差，同时因分时电价的引入使得用户费用有所降低。 |

| Developing the electric vehicle industry vigorously is a new measure to alleviate the fossil energy crisis, but its disordered charging mode will aggravate the load peak-valley difference and affect the safe and stable operation of the power system. In order to solve the above problems, an orderly charging and discharging strategy for EV considering user charge delay time is proposed. A multi-objective optimization model with standard deviation of load and user cost is established, taking the remaining electricity and charge and discharging limit of adjacent time intervals as constraints. A non-dominated sorting genetic algorithm-II with elite strategy is used to solve the mode. Finally, its optimal compromise solution is obtained. The example shows that the optimal delay time can be obtained by the model under different constraints. The peak-valley difference of load can be reduced within the limited charging time of users, and user cost can be reduced due to the time-sharing tariff. |
