论文摘要
COVID-19的大流行通过强迫关闭并改变了全球互动的方式来影响我们的社会。关于对电网的影响，它在全球的能源需求大幅下降。最近的研究表明，由COVID-19锁定与大型可再生能源产生相结合的低需求条件导致了极低的惯性网格条件。在这项工作中，我们检查了攻击者如何通过执行针对低率电力系统中数十万IOT IOT连接的高战斗负载来损害数十万IOT连接的高战斗负载来利用这些{场景}来引起不安全的网格操作条件。我们的研究重点是分析COVID-19缓解措施对美国区域传输运营商（RTO）的影响，制定了针对具有低惯性条件的传输系统的合理且现实的最小制LAA，并评估了这些大型LAA的可能性。理论和仿真结果基于WSCC 9-BUS {和IEEE 118-BUS}测试系统。结果表明，对手如何通过针对低惯性系统中的脆弱负载总线来引起重大频率干扰，并提供有关如何考虑生成调度的可再生能源的时间波动，影响了网格对LAAS的脆弱性。
The COVID-19 pandemic has impacted our society by forcing shutdowns and shifting the way people interacted worldwide. In relation to the impacts on the electric grid, it created a significant decrease in energy demands across the globe. Recent studies have shown that the low demand conditions caused by COVID-19 lockdowns combined with large renewable generation have resulted in extremely low-inertia grid conditions. In this work, we examine how an attacker could exploit these {scenarios} to cause unsafe grid operating conditions by executing load-altering attacks (LAAs) targeted at compromising hundreds of thousands of IoT-connected high-wattage loads in low-inertia power systems. Our study focuses on analyzing the impact of the COVID-19 mitigation measures on U.S. regional transmission operators (RTOs), formulating a plausible and realistic least-effort LAA targeted at transmission systems with low-inertia conditions, and evaluating the probability of these large-scale LAAs. Theoretical and simulation results are presented based on the WSCC 9-bus {and IEEE 118-bus} test systems. Results demonstrate how adversaries could provoke major frequency disturbances by targeting vulnerable load buses in low-inertia systems and offer insights into how the temporal fluctuations of renewable energy sources, considering generation scheduling, impact the grid's vulnerability to LAAs.
