摘要

综合能源系统分布式经济调度日益依赖通信网络，其信息安全面临严峻威胁。现有研究多局限于防御者视角，缺乏对隐蔽性经济攻击的先验认知，难以实现主动防御。为此，从攻击者视角提出一种面向储能与负荷的最优协同攻击策略，旨在探明系统安全底线、以攻促防。首先，构建电 - 热 - 气系统经济调度模型并设计完全分布式求解算法。其次，利用储能与负荷的防护薄弱性，设计三阶段协同攻击框架。通过前两阶段隐蔽的数据完整性攻击与第三阶段适时引入的拒绝服务攻击相配合，迫使系统收敛至经济性显著劣化的可行运行点。理论推导了 DoS 攻击的最佳启动时机。仿真表明了该策略在满足系统物理约束的前提下使系统总经济效益从 3462.9 元降至 2786.1 元，造成约 19.54% 的经济损失，并通过不同 DoS 攻击时刻的对比进一步验证了最优 DoS 攻击时刻与前两阶段数据完整性攻击时序的一致性。研究证实了深入剖析攻击机理是构建针对性防御体系的关键前提。

Abstract

The distributed economic dispatch of integrated energy systems is increasingly dependent on communication networks

making its information security vulnerable to severe cyber threats. Existing research is mostly limited to the defender's perspective

and lacks priori understanding of stealthy economic attacks

making proactive defense difficult to achieve. To address this issue

this paper proposes an optimal coordinated attack strategy for energy storage systems and loads from the attacker's perspective

aiming to identify the security boundary of the system and promote defense through attack analysis. First

an economic dispatch model for an electricity-heat-gas integrated energy system is constructed

and a fully distributed solution algorithm is designed. Subsequently

a three-stage coordinated attack framework is designed by taking advantage of the protection weakness of energy storage systems and loads. By combining stealthy data integrity attacks in the first two stages with a timely introduced denial-of-service (DoS) attack in the third stage

the system is forced to converge to a feasible operation point with significant economic deterioration. The optimal triggering time of the DoS attack is deduced theoretically. Simulation results show that

while satisfying all physical constraints

the proposed strategy reduces the total economic benefit of the system from 3462.9 RMB to 2786.1 RMB

resulting in an economic loss of approximately 19.54 %. Furthermore

comparisons under different DoS attack timings verify the consistency between the optimal DoS attack timing and the scheduling sequence of the first two-stage data integrity attacks. This study confirms that an in-depth understanding of attack mechanisms is a key prerequisite for building targeted defense systems.
