Asymmetric Information in Military Microgrid Confrontations—Evaluation Metric and Influence Analysis

Abstract

Due to the wide integration of information technology in equipment and weapons, a stable and reliable power supply has become one of the pivotal factors in modern warfare to achieve victory. As a critical infrastructure to provide continuous energy supply during long-duration electrical outage, military microgrid always suffers fierce attacks from the enemy. In order to improve the defense effect, a lot of investigation has been made into resource allocation, Distributed Generator (DG) distribution, network reconfiguration, and so forth. Nevertheless, the information gap between defender and attacker has not been considered in the literature. Therefore, this paper is intended to highlight this information mismatch to appeal for community attention and evaluate its capability to improve defensive performance. Firstly, a novel assessment metric is proposed to identify the level of asymmetric information. Then, an Attacker-Defender (AD) model is developed to describe the zero-sum game between two opposite agents, which is subsequently tackled with dual theory and big-M method. Finally, three cases ranging from 6-bus to 57-bus are utilized for numerical experiments to analyze the influence of asymmetric information on military microgrid confrontation. Results on various levels of attack strength validated the effectiveness and significance of asymmetric information in eliminating the attack damage and improving the defensive performance.

Future National Energy Systems, Energy Security and Comprehensive National Defence

“…From Scenario 0, three near-future scenarios are developed: Scenario A, B, and C. Scenario A is a near future where local or microgrid solutions have been progressively implemented in private homes, public buildings, farms, small communities, and military installations, e.g., Kumar et al [31], Pérez et al [32], and [2]. The capability for local and private wind, solar, and bioenergy production has in Scenario A increased so that these sources locally in many areas contribute to 30% of the peace-time energy consumption.…”

“…NATO defines "resilient energy supplies" as one of a nation's seven baseline requirements [1]. In research, this dependence is addressed at the component level, e.g., in relation to military microgrids [2,3] and infrastructure protection coordination [4]. However, constructive suggestions for how to develop energy security, taking national defence into consideration, are limited.…”

Defense Installation Energy Resilience for Changing Operational Requirements

“…Although civilian customers may be unhappy with the inconvenience of power interruptions, the potential consequences of a civilian power outage are relatively low compared to those of defense installation outages. Due to national security requirements for resilient electrical power supply on defense installations, consumer interest in locally resilient power supply, and renewable energy goals, there have been many recent publications demonstrating microgrids as a successful and practical electrical resilience measure [3,12,[15][16][17][18][19][20][21][22][23][24][25].…”

Multistage Attack–Defense Graph Game Analysis for Protection Resources Allocation Optimization Against Cyber Attacks Considering Rationality Evolution

“…Jiang et al. have evaluated the capability and effectiveness of asymmetric information in mitigating the attack and improving the defense performance (Jiang, Huang, & Zhang, 2020). Dynamic analysis of information diffusion has been considered (Jiang et al., 2014).…”

“…Zeng studied a Stackelberg game under asymmetric network structure information to reveal the effectiveness of disclosing false information, where the defender has complete information while the attacker only obtains topology information disclosed intentionally by the defender (Zeng, Ren, Li, Liu, & Chen, 2019). Jiang et al have evaluated the capability and effectiveness of asymmetric information in mitigating the attack and improving the defense performance (Jiang, Huang, & Zhang, 2020). Dynamic analysis of information diffusion has been considered (Jiang et al, 2014).…”
