Différentes approches ont déjà été utilisées pour modéliser les infrastructures critiques ainsi que leurs interdépendances en vue de leur sécurisation. Elles permettent de caractériser les systèmes critiques interconnectés afin de faciliter l'analyse de risques et la définition de méthodes et de mécanismes locaux et globaux de sécurisation efficaces. Cet article présente un état de l'art des méthodes adaptées à la modélisation des réseaux électriques et à leur dépendance aux systèmes TIC associés. Nous présenterons des approches basées sur la théorie des réseaux (ou systèmes) complexes, sur des outils spécialisés communicants (co-simulateur), sur des agents, sur les réseaux de Petri ou sur l'utilisation des BDMP (Boolean logic Driven Markov Processes.

ICT have enabled improving the control of the power grid and by consequence the reliability and the flexibility of these systems. Presently, ICT are a key aspect in the smart grids development. Today’s power systems depend on ICT. However, these technologies

Failure in oneinfrastructure may cascade on others. ... To illustrate, the effects of a faulty router in the telecommunication network that cascade in the electrical infrastructure are presented. ...

The focus is especially on the electric network management applications. The steps of this procedure are illustrated in a case study based on an industrial simulation tool performing technical operating tasks in distribution utilities. The obtained criticality hierarchy in our use case is correlated

ICT have enabled the improvement of the power grid control and by consequence the reliability and the flexibility of these systems. Presently, ICT are a key aspect in the smart grids development. Today's power systems depend on ICT. However, these technologies can fail and are also exposed to threats that can affect their functioning and the operation of the power system. Therefore, it is very important to consider both interconnected infrastructures (electrical power grid and its information and communication system (ICS)) in the modeling, design and security analysis of electrical power systems. In this paper, we present simulation results illustrating correlations between the electric network state and the ICS state.
