“…In practical applications, another matrix called the consequent event matrix (CEM) is used to identify the specific physical components affected in each event. An implementation on the extended Roy Billinton Test System (RBTS) has been presented in [26]. The results clearly show the impact of cyber failures on power grid reliability.…”

“…The results clearly show the impact of cyber failures on power grid reliability. Studies in [25] and [26] mainly focus on the aspect of protection because protection hidden failures are common causes of cascading outages [27], [28]. A similar conditional probability matrix was used in [29] to model the effects of failures in generation rejection schemes, and to determine their impact on optimal system operation.…”

“…Lei et al designed a typical IEC-61850-based protection system incorporating physical and cyber components, and developed the cyber-physical interface matrix (CPIM) which defined the relationship between the cyber subsystems and physical subsystems in terms of failure modes and effects [18]. Then, the concepts were extended from substation to integrated system, and the consequent event matrix (CEM) was established to provide detailed information about affected transmission lines [19]. The applications of CPIM and CEM could decouple the cyber part analysis from the physical part analysis, and provide a more tractable method for CPPS reliability assessment.…”

Conventional power systems are developing into cyber-physical power systems (CPPS) with wide applications of communication, computer and control technologies. However, multiple practical cases show that the failure of cyber layers is a major factor leading to blackouts. Therefore, it is necessary to discuss the cascading failure process considering cyber layer failures and analyze the vulnerability of CPPS. In this paper, a CPPS model, which consists of cyber layer, physical layer and cyber-physical interface, is presented using complex network theory. Considering power flow properties, the impacts of cyber node failures on the cascading failure propagation process are studied. Moreover, two vulnerability indices are established from the perspective of both network structure and power flow properties. A vulnerability analysis method is proposed, and the CPPS performance before and after cascading failures is analyzed by the proposed method to calculate vulnerability indices. In the case study, three typical scenarios are analyzed to illustrate the method, and vulnerabilities under different interface strategies and attack strategies are compared. Two thresholds are proposed to value the CPPS vulnerability roughly. The results show that CPPS is more vulnerable under malicious attacks and cyber nodes with high indices are vulnerable points which should be reinforced.
