“…There is also focus on the disruption of specific common attacks in the smart grid. Game theory based defense strategies against DoS attacks are proposed which use Nash Equilibrium to maintain dynamic stability in an attacked system [125,126]. Minimizing the effects of jamming attacks is also studied through a modified version of contract network protocol (CNP) as a negotiation protocol among agents [127].…”

The integration of sensors and communication technology in power systems, known as the smart grid, is an emerging topic in science and technology. One of the critical issues in the smart grid is its increased vulnerability to cyber threats. As such, various types of threats and defense mechanisms are proposed in literature. This paper offers a bibliometric survey of research papers focused on the security aspects of Internet of Things (IoT) aided smart grids. To the best of the authors' knowledge, this is the very first bibliometric survey paper in this specific field. A bibliometric analysis of all journal articles is performed and the findings are sorted by dates, authorship, and key concepts. Furthermore, this paper also summarizes the types of cyber threats facing the smart grid, the various security mechanisms proposed in literature, as well as the research gaps in the field of smart grid security.

“…Yi et al [33] presented a DoS attack scenario that lowers packet delivery rate by 10-20% in the AMI network. Srikantha et al [27] considered the effect of a DoS attack on the power system. Hahn et al [13] introduced a security model to represent privilege states and evaluated viable attack paths in the AMI network.…”

“…The simulation work in [30] only included a 3-generator system, which is small to fully understand the impact of these attacks on real power systems. The communication network is not considered in quantifying the cyber-physical system impact in [19] and [27]. Hahn et al [12] described a cyber-physical testbed.…”

The Smart Grid (SG) is vulnerable to cyber-attacks due to its integration with a variety of information, communication and control technologies. If undetected by deployed security systems, cyber-attacks could damage critical power system infrastructure and disrupt service to a very large number of energy customers. In particular, cyber attackers could hijack the smart grid by injecting malicious commands. To provide insight into these concerns, we propose an approach that develops a new tool for the real-time Cyber-Physical Security Assessment (CPSA) of malicious control commands that target physical SG components. The tool is able to detect and protect the system against known Trojans (such as BlackEnergy). It also efficiently and effectively monitors the health of the power system in real-time and detects the presence of malicious commands. The security analysis of our approach includes a look at three system-generated metrics: system susceptibility, access points, and threat capability. The performance analysis includes a look at the system overhead, scalability, accuracy, robustness, and execution and response time. Our proposed approach was tested on a 42-bus power system with 24 substations. The developed tool could be extended and used by power system operators to assess and mitigate the impact of cyber-attacks on the smart grid.

“…A DoS attack is launched by attackers whose aim is to cause lack of service availability, e.g., a power outage affecting customers and distribution system operators alike. For a distribution grid with a networked control system, DoS attacks can take many forms [16]. For instance, the attacker can flood the communication network with useless requests to exhaust the network resources and thus suspend the exchange of messages carrying control signals.…”

Incorporating information and communication technology in the operation of the electricity grid is undoubtedly contributing to a more cost-efficient, controllable, and flexible power grid. Although this technology is promoting flexibility and convenience, its integration with the electricity grid is rendering this critical infrastructure inherently vulnerable to cyberattacks that have potential to cause large-scale and farreaching damage. In light of the growing need for a resilient smart grid, developing suitable security mechanisms has become a pressing matter. In this work, we investigate the effectiveness of a model-free state-of-the-art attack-detection method recently proposed by the cybersecurity community in detecting common types of cyberattacks on voltage control in distribution grids. Experimental results show that, by monitoring raw controller and smart-meter data in real time, it is possible to detect denial of service, replay, and integrity attacks, thus contributing to a resilient and more secure grid.
