| 摘要: |
| 在电动汽车（EV）行驶统计规律的基础上，提出EV智能接入模式下的微网优化调度模型，微网调度机构根据不同EV用户需求、可再生能源功率、其他负荷功率以及EV充放电过程需满足的约束，给出包括EV在内的微网内所有设备的运行策略。该模型可利用CPLEX软件求解。以14节点微网系统为例，分别对EV随机充电模式、错峰充电模式以及智能接入模式下的微网调度运行进行优化，结果表明，智能接入模式下的EV作为分散式储能单元，与微网内集中式储能元件协调配合，发挥移峰填谷的作用，更具经济性。 |

| Abstract: |
| Based on the statistical regularity of EV（Electric Vehicle） driving，a model of optimal microgrid dispatch in smart EV integration mode is proposed and solved by CPLEX，with which and according to the requirements of EV owners，the power of renewable energy and other loads，and the constraints of EV charging／discharging，the microgrid dispatch organization generates the optimal operating strategies for all devices in microgrid，including EVs. As an example，the dispatch of a 14-bus microgrid is optimized in random EV charging mode，off-peak EV charging mode and smart EV integration mode respectively. Results show that，EVs can be economically used in smart integration mode as the distributed energy storage devices to coordinate with the centralized energy storage devices in microgrid for load shifting. |
