“…To ensure the safe and stable operation of the CPPS system and avoid the occurrence of chain failures, the system should have the ability to self regulate and reduce system losses. There have been numerous publications on the performance indicators of regulation methods and strategies for the study of CPPS cascading failures and system regulation mechanisms [7][8][9]. To maintain the power balance and stability of the power system, disconnecting a portion of the load from the grid is called load shedding.The load shedding operation of the power grid is an important means to ensure the safe and stable operation of the power grid [10,11], and the value of the load power change caused by the load shedding operation is called the load shedding amount.…”

With the development of power technology and communication technology, the power grid and power communication network have become interdependent and closely coupled. The load shedding operation of the power grid is an important means to reduce the occurrence of chain faults and ensure the safe and stable operation of the power grid. Based on the transmission of load control services in the communication network, this paper establishes a model for a dual-network coupled cyber physical power system (CPPS). Considering communication edge faults, the associated load capacity of the communication edge and the expected load loss of the power grid are defined. On this basis, the paper proposes a complete information zero-sum game mechanism called “defense attack defense” for communication edge failures, which takes the expected loss of load from the power grid as the benefit. The paper studies the optimal attack and defense game strategies and provides the algorithm implementation process for the three stages of the game. Considering the bandwidth capacity of the communication edge, this paper uses the Dijkstra algorithm or k shortest paths (KSP) algorithm with the cost factor of the communication edge as the weight to plan the main and backup communication channels for multiple load control services. The simulation results show that the game mechanism proposed in this paper can effectively reduce the expected load loss from the power grid and improve the stability of the CPPS.

This paper presents a framework for integrated cyber-physical security propagation study within critical infrastructures (hospitals use case). The framework includes an ontology for the semantic modeling of cyber-physical security. The impact propagation approach relies on propagation rules inferring the cascading effects of security incidents occurring in hospitals. An impact score module allows evaluating impacts' severity, considering implemented protection measures. This work is part of the European project SAFECARE, which provides a set of tests and demonstration sessions in partnership with 3 hospitals in Europe. During these tests, we measured effectiveness and efficiency metrics, as well as end users' satisfaction feedback. Experiments performed on real attack scenarios, show high effectiveness rates and a common agreement from end-users about the added value of the solution to enhance risks analysis practice and increase hospitals mitigation strategies efficiency.
