摘要
多能流调度利用信息技术打破了传统能源系统间的壁垒,构建了高效、互补的供能体系。然而,能源系统间大量测控数据的传输也加剧了其遭受网络攻击的风险。为深入探究综合能源系统(IES)中虚假数据注入攻击(FDIA)潜在的攻击模式,提出一种面向分布式调度的电-气协同FDIA建模方法。该方法考虑了IES中电力和燃气不同管理主体的影响,建立了分布式双层规划模型,并结合交替方向乘子法设计了双层嵌套分布式求解框架,保护了各主体数据隐私。采用凸松弛技术将燃气系统中Weymouth方程转化为易于处理的凸约束形式,便于模型的高效求解。在IEEE 39节点和比利时20节点互联的电-气IES中进行测试,结果表明协同FDIA的破坏效能可通过耦合设备在系统中传播,导致系统近70%的负荷被强制切除。分布式求解算法可在有限迭代步数内收敛,与集中式方法的相对误差控制在1.4%以内,所提方法为分析分布式架构下IES中的FDIA攻击模式提供了有效工具。
Multi-energy flow scheduling utilizes information technology to break down the barriers between traditional energy systems,thereby forming an efficient and complementary energy supply system.However,the transmission of a large amount of measurement and control data between energy systems also increases their risk of being subjected to cyberattacks.To clarify the potential attack patterns of false data injection attacks(FDIA)in integrated energy systems(IES),a distributed schedulingoriented modeling method for coordinated FDIA in the electricity-gas system was proposed.This method considered the influence of different management entities of electricity and gas in the IES,and established a distributed bilevel programming model.Additionally,it designed a bilevel nested distributed solution framework by integrating the alternating direction method of multipliers,protecting the privacy of data from each entity.Meanwhile,convex relaxation techniques were used to transform the Weymouth equation in the natural gas system into a tractable convex constraint form,facilitating the efficient solution of the model.Tests were conducted in an electricity-gas IES interconnected with the IEEE 39-bus and the Belgian 20-bus systems.The results showed that the destructive effect of the coordinated FDIA could be transmitted through coupling devices in the system,forcing the system to shed nearly 70%of the load.Meanwhile,the distributed solution algorithm could converge within a limited number of iterations,and the relative error compared with the centralized method was controlled within 1.4%.The proposed method provides an effective tool for analyzing the attack patterns of FDIA in IES under distributed architectures.
