摘要(Abstract)：

随着信息和通信技术的快速发展，电力系统已发展为信息系统和物理系统深度耦合的CPS（信息物理系统），信息流与电力流的不断交互使电网面临着潜在的网络攻击风险。以PMU（相量测量单元）作为攻防目标，提出一种多阶段低代价FDIA（虚假数据注入攻击）方法。首先，构建虚假数据，确定PMU最优配置，优化攻击范围并量化攻击后果；其次，基于双人零和博弈理论求解纳什均衡点，得到博弈模型的最优攻防策略；最后，在IEEE 30节点系统上仿真，基于单阶段博弈结果，在不同攻击场景下实施多阶段低代价攻击。研究结果表明：低代价线路花费的攻击代价明显偏低，并且对电力系统的稳定运行造成了影响，验证了所提多阶段攻击模型的有效性与适用性。
With the rapid development of information and communication technology, the power system has developed into a cyber physical system(CPS) in which the information system and the physical system are deeply coupled. The constant interplay between data flow and power flow exposes power grid to potential cyber attack risks.The phasor measurement unit(PMU) is taken as the attack and defense target in power system, and a multi-stage low-cost false data injection attack(FDIA) model is presented. Firstly, false data are generated to determine the optimal configuration of PMUs, optimize the attack range and quantify the attack consequences. Secondly, the Nash equilibrium is solved based on the two-player zero-sum game theory to obtain the optimal attack and defense strategies of the game model. Finally, the simulation is performed on an IEEE 30-node system, and the multi-phase lowcost attack is implemented in different attack scenarios based on the results of the single-phase game. The research findings show that the attack cost spent on the low-cost line is significantly low and affects the stable operation of the power system, which verifies the effectiveness and applicability of the proposed multi-stage attack model.
