“…Furthermore, the literature includes many studies– that address this problem in complex systems, many of which cover the domain of power grids, which represent typical CPSs. In power grids, it has been proven that they have a higher rate of occurrences with effects such as electrical instability and large blackouts –. The work of Babalola et al prevents cascading failures in the smart grid by leveraging a multi‐agent system and an algorithm based on mathematical combinations to re‐dispatch the power from the generators in case of multiple contingencies.…”

The mathematical combinations used by the system's algorithm in case of fault occurrences are selected based on empirical historical economic dispatch data.…”

Summary The complexity of cyber‐physical systems (CPSs) opens up several challenges regarding the assurance of high levels of reliability. Therefore, we need to develop a new data quality analysis and new CPS components/subsystems for the detection, isolation, recovery, and prevention of failures and intrusion events. Furthermore, we have to develop new reliability assessment models and metrics in order to properly evaluate CPSs. Agent technologies, through their characteristics such as autonomy, social ability, reactivity, and proactivity, have the potential to address these challenges and requirements. We propose a multi‐agent based solution, namely ReliaCPS, for detecting and preventing the failures of the system components of CPSs. We also use a case study of a CPS for monitoring ambient parameters to evaluate the performance of the proposed approach. Our results indicate improvements in terms of reliability metrics (32.69% for the mean time between failures and mean time to failure, 50% for the mean time to repair and 0.94% for reliability function over time).

“…As for how to effectively model critical infrastructures with interdependent relationships, Rinaldi established the interdependent network system using dynamic simulation and identified the range of cascading security operation [7]. According to the complex relationship between the power system and the rapid processing data network, Cai et al established an interdependent network model to analyze the complex effects caused by cascading failures [8]. The modern society relies on the complex network of critical infrastructure 2 Journal of Electrical and Computer Engineering systems (such as power networks, telecommunication networks, transportation networks, and water supply systems).…”

Recent studies have shown that random nodes are vulnerable in interdependent networks with simple coupling. However, relationships in actual networks are interrelated and complex coupling. This paper analyzes the vulnerability of interdependent scale-free networks with complex coupling based on the BA model. The results indicate that these networks have the same vulnerability against the maximum node attack, the load of the maximum node attack, and the random node attack, which explain that the coupling relationship between network nodes is an important factor in network design.

“…Researchers have noted that demand-side resources should be considered when determining the priority of power loads, although no specific method was given. With the development of ICT [18], a high-speed, reliable, and secure data communication system now provides support for better observability and controllability of an entire power system, making it possible to use active power loads to respond to a UFLS process.…”

Abstract:The construction of a cyber physical system in a power grid provides more potential control strategies for the power grid. With the rapid employment of intelligent terminal equipment (e.g., smart meters and intelligent appliances) in the environment of a smart grid, abundant dynamic response information could be introduced to support a secure and stable power system. Combining demand response technology with the traditional under-frequency load shedding (UFLS) scheme, a new UFLS strategy-determining method involving intelligent appliances is put forward to achieve the coordinated control of quick response resources and the traditional control resources. Based on this method, intelligent appliances can be used to meet the regulatory requirements of system operation in advance and prevent significant frequency drop, thereby improving the flexibility and stability of the system. Time-domain simulation verifies the effectiveness of the scheme, which is able to mitigate frequency drop and reduce the amount of load shedding.
