ÉVALUATION DU RISQUE POUR LA SÉCURITÉ DES RÉSEAUX ÉLECTRIQUE FACE AUX ÉVÉNEMENTS INTENTIONNELS

Abstract : Power systems are critical infrastructures which are highly interconnected and highly interdependent on other basic infrastructures on which basic human activities depend. Due to this relevance, the electrical sector has been and will continue to be a target of terrorist groups. The ability to deal with these terrorist situations depends on the anticipation capacity, the reflection in times where there is no crisis and the operational management of the owners of the utilities. Therefore, contingencies resulting from terrorism must be taken into consideration when assessing security. This thesis presents a method based on the evaluation of risk, which enables operators and planners to assess the power system security with regard to possible terrorist acts. By using probabilistic inference and theory of possibilities, we consider the uncertainty associated with the dynamic of terrorism as well as the uncertainty associated to load and generation forecasting. We attempt to take into account potential cyberattacks on the communication system of the power system, which can affect the security as a whole. The methods are validated with test systems, taking as example terrorist attacks on the Colombian electrical infrastructure.
