针对电网信息物理系统（cyber physical system,CPS）遭受虚假数据注入攻击（false data injection attack,FDIA）致使电网发生大规模停电的问题，提出一种电网CPS配置测量保护装置防御FDIA的防御-攻击-防御三层优化模型。上层防御模型考虑通信路由传输约束，辨识测量保护装置的配置位置；中层攻击模型考虑通信路由传输风险，辨识FDIA导致电力系统负荷损失费用最大化注入最坏攻击位置；下层运行模型根据上层和中层辨识出的配置和最坏攻击位置决策调度电力系统安全运行。最后，通过算例仿真分析，结果表明，所提模型能够有效提高通信路由的抗干扰能力，提升电网CPS的韧性。
Abstract：The cyber physical system(CPS)of power grid suffers from false data injection attack(FDIA),which leads to large-scale power outages. Aimed at this problem,a defense-attack-defense tri-level optimization model for the defense against FDIA is put forward,which is based on the CPS of power grid with the installation of measurement protection devices. In the upper-level defense model,the communication routing delivery constraints are considered to identify the installing location of measurement protection devices. In the middle-level attack model,the communication routing delivery risk is taken into account to identify the worst attack location for the power system that maximizes the load loss cost. According to the installation and the worst attack location identified by the upper-and middle-level models,the dispatching decisions on the safe operation of the power system are determined by the lower-level defense model. Finally,simulation analysis is performed on examples,and results show that the proposed model can effectively improve the anti-interference capability of communication routings and the resilience of the CPS of power grid.
