摘　　要：随着电动汽车的大规模并网,配电网对新能源的消纳能力大幅提升,但同时充电桩的低安全性、高可及性也进一步降低了配电网网络安全。文章首先提出一种基于一致性算法的分布式能量管理策略,将电动汽车集群视为具有源-荷双向特性的储能设备,以实现完全分布式经济调度。考虑到通信延时下,拒绝服务攻击以及面向电动汽车的新型数据完整性攻击的存在,提出了一种结合隐私保护协议和隔离机制的抗扰控制策略,以实现网络攻击下系统的能量有效管理及经济运行。最后通过算例仿真对比,验证了该加密机制的有效性及控制策略的可行性。Modern power system has developed into cyber-physical system(CPS),which is highly integrated between power network and information network.However,advanced information technology not only improves system performance,but also introduces new security risks.With the large-scale grid-connection of Electric Vehicle(EV)with mobile energy storage equipment,the absorption capacity of distribution network for new energy has been greatly improved.However,the low security and high accessibility of charging piles have further reduced the network security of distribution network.On this basis,a distributed energy management strategy based on consistency algorithm is firstly proposed in this paper,which considers the EV cluster as an energy storage device with source-charge bidirectional characteristics to achieve fully distributed economic scheduling.Considering denial of service attacks and new data integrity attacks for electric vehicles,a disturbance rejection control strategy combining privacy protection protocol and isolation mechanism is proposed to achieve effective energy management and economic operation of systems under network attacks.Finally,the effectiveness of the encryption mechanism and the feasibility of the control strategy are verified by simulation.
