摘要:

智能电网的设想是通过利用消费者和运营商之间的双向通信渠道,显着提高能源消耗的效率。例如,运营商可以适时地利用能量需求的延迟容限,以便随着时间的推移平衡能量负载,从而降低总运营成本。然而,这个机会也伴随着安全威胁,因为电网变得更容易受到网络攻击。在本文中,我们研究了这种恶意网络攻击对简化设置中电网能效的影响。更确切地说,我们考虑一个简单的模型,其中智能电网消费者的能量需求被拦截和改变的主动攻击者之前,他们到达的运营商,谁配备了有限的入侵检测能力。我们制定的运营商和攻击者所面临的优化问题,并提出了几个调度和攻击双方的策略。有趣的是,我们的研究结果表明,与促进智能电网的成本降低相反,增加能量需求的延迟容忍度可能会使攻击者迫使系统增加成本。这突出了需要精心构造和强大的入侵检测机制在运营商。

英文摘要:

The smart grid is envisioned to significantly enhance the efficiency of energy consumption, by utilizing two-way communication channels between consumers and operators. For example, operators can opportunistically leverage the delay tolerance of energy demands in order to balance the energy load over time, and hence, reduce the total operational cost. This opportunity, however, comes with security threats, as the grid becomes more vulnerable to cyber-attacks. In this paper, we study the impact of such malicious cyber-attacks on the energy efficiency of the grid in a simplified setup. More precisely, we consider a simple model where the energy demands of the smart grid consumers are intercepted and altered by an active attacker before they arrive at the operator, who is equipped with limited intrusion detection capabilities. We formulate the resulting optimization problems faced by the operator and the attacker and propose several scheduling and attack strategies for both parties. Interestingly, our results show that, as opposed to facilitating cost reduction in the smart grid, increasing the delay tolerance of the energy demands potentially allows the attacker to force increased costs on the system. This highlights the need for carefully constructed and robust intrusion detection mechanisms at the operator.
