摘　　要：以城市交通中的电动汽车充放电网络这一典型的信息物理系统为应用背景,提出移动微网的概念。分析了电动汽车路面无线充放电的移动微网特点,并研究了其典型的体系结构。基于电动汽车无线充放电网络和交通网络特点,建立了移动微网的分析模型。研究了移动微网优化运行的改进差分进化算法,考虑电动汽车行驶中充放电及交通信息,可实现对节点功率正常、紧急及故障情况下的优化控制。仿真结果表明:移动微网正常运行时,通过电动汽车移动电能实现节点间20%以上的功率转移,提高20%左右太阳能消纳量,故障情况下根据电动汽车可用移动储能容量最大限度实现对配网重要负荷的支撑。The electric vehicle charging and discharging network in the city traffic system is regard as a typical Cyber Physical System. On the basis of this application background, we put forward a concept of mobile microgrid. The mobile microgrid may be established on the basis of electric vehicle wireless charging and discharging on the road, the characteristics of which are analyzed. Then the typical architectures are researched. Based on the characteristics of electric vehicle wireless charging and discharging network as well as traffic network, a mathematical analysis model of mobile microgrid is established. Moreover, the improved differential evolution algorithm of mobile microgrid optimization operation is studied, which can realize the optimization control of normal, emergency, and fault model, with the electric charge and discharge information and traffic information. The simulation results show that more than 20% of power is transferred between the nodes by electric vehicles, and amount of solar power generation absorption is increased by about 20% in normal mode. According to the available mobile power storage capacity, mobile mocrogrid may provide great support for import load in fault mode.
