论文摘要
随着智能电网通过双向通信的改善,需求响应(DR)由于将非关键载荷从高峰时段转移到非高峰期提供的固有灵活性而引起了重大关注,这可以大大提高网格可靠性并降低能源成本。操作员利用DR来增强运营灵活性并减轻网络拥塞。但是,智能的双向交流容易受到网络攻击的影响。本文研究了DR在安全受限的经济调度(SCED)中的好处,然后研究了当网络攻击以DR信号为目标时,系统脆弱性。本文提出了一个错误的需求响应信号和负载测量注入(FSMI)网络攻击模型,该模型在黑客测量时发送错误的DR信号,以使攻击无法检测到。 IEEE 24总线系统的仿真结果(i)证明了需求响应的省略成本优势,并且(ii)在FSMI攻击下更改需求响应信号时显示了显着的线重载。
With improvement in smart grids through two-way communication, demand response (DR) has gained significant attention due to the inherent flexibility provided by shifting non-critical loads from peak periods to off-peak periods, which can greatly improve grid reliability and reduce cost of energy. Operators utilize DR to enhance operational flexibility and alleviate network congestion. However, the intelligent two-way communication is susceptible to cyber-attacks. This paper studies the benefits of DR in security-constrained economic dispatch (SCED) and then the vulnerability of the system to line overloads when cyber-attack targets DR signals. This paper proposes a false demand response signal and load measurement injection (FSMI) cyber-attack model that sends erroneous DR signals while hacking measurements to make the attack undetectable. Simulation results on the IEEE 24-bus system (i) demonstrate the cost-saving benefits of demand response, and (ii) show significant line overloads when the demand response signals are altered under an FSMI attack.
