“…The Bayesian attack graph model is used to assess the attack procedure and the likelihood of compromise of the cyber components in smart grid systems with the consideration of uncertainty in cyber-attacks [95]. The attack graph model is useful for the operators to analyze the patterns of sequential cyber topological attacks in identifying the critical cyber-attacks thereby cascading outages can be avoided in the CPPS [283].The attack graph serves various applications like intrusion detection, security defence, network security, and forensic analysis, etc. Overall, it gives a bird's eye view of every attack scenario in CPPS that can lead to a critical security breach.…”

Cyber-Physical System (CPS) is a new kind of digital technology that increases its attention across academia, government, and industry sectors and covers a wide range of applications like agriculture, energy, medical, transportation, etc. The traditional power systems with physical equipment as a core element are more integrated with information and communication technology, which evolves into the Cyber-Physical Power System (CPPS). The CPPS consists of a physical system tightly integrated with cyber systems (control, computing, and communication functions) and allows the two-way flows of electricity and information for enabling smart grid technologies. Even though the digital technologies monitoring and controlling the electric power grid more efficiently and reliably, the power grid is vulnerable to cybersecurity risk and involves the complex interdependency between cyber and physical systems. Analyzing and resolving the problems in CPPS needs the modelling methods and systematic investigation of a complex interaction between cyber and physical systems. The conventional way of modelling, simulation, and analysis involves the separation of physical domain and cyber domain, which is not suitable for the modern CPPS. Therefore, an integrated framework needed to analyze the practical scenario of the unification of physical and cyber systems. A comprehensive review of different modelling, simulation, and analysis methods and different types of cyber-attacks, cybersecurity measures for modern CPPS is explored in this paper. A review of different types of cyber-attack detection and mitigation control schemes for the practical power system is presented in this paper. The status of the research in CPPS around the world and a new path for recommendations and research directions for the researchers working in the CPPS are finally presented.

The expansion of the electric power communication network year by year has enabled a large number of intelligent terminals to be accessed exponentially. Massive intelligent terminals connected to the power communication network have a huge processing demand, which causes a heavy maintenance burden on the equipment of communication networks. In order to solve this problem, this study proposes a flexible communication mechanism based on the device-to-device (D2D) technique for the intelligent terminals to deal with the processing pressure of massive information in the network. This proposed mechanism introduces where and how to use the D2D technique. In this study, this communication mechanism makes terminals give a high priority to transferring the information of important services. The D2D communication model is formulated for this communication mechanism, and the influence of different conditions on the D2D communication is analysed. The D2D communication mechanism is simulated to optimise the existing network indexes, such as traffic and sum of service level.

With the increasingly close coupling between the cyber network and the physical power grid in Cyber Physical Power System (CPPS), the failure of cyber network has become an important cause of blackout. Equipment failure or abnormal operation state will be appeared without alarm in complex cyber network, which brings hidden failures not been diagnosed and dealt with in time. The invisibility and harmfulness of hidden failures pose a significant threat to the safe, reliable, and stable operation of CPPS. The dual hidden cascading failure model for CPPS is proposed to reveal the failure characteristics of CPPS accurately, considering not only the hidden faults in the power grid, but also the hidden failures in the cyber network. With the different coupled relationships between power systems and cyber networks, the cyber network topology with corresponding failure threshold is obtained according to the simulation of the model with different hidden failure rates of cyber network nodes. When the hidden failure rate is lower than the failure threshold, the scale-free topology cyber network coupled mode is adopted between power grids and cyber networks, otherwise the small-world topology cyber network coupled mode is adopted, which can effectively reduce the risk of power system blackouts. The method proposed in this paper is tested by using IEEE-118 power system and its cyber network. The results show that the method is effective.
