Electric Power Systems are critical infrastructures that provide vital services for the human activities; assessing their dependability is thus an high priority task. This paper presents an ad-hoc simulator for the evaluation of depend- ability and performability measures in Electrical Power System (EPS). Our stochastic model is composed by sepa- rated and simple submodels of the dynamics of the two sub- systems composing EPS: the Electrical Infrastructure and the Computer-based Control System. By providing explicit modeling of the interdependencies between the main sub- systems, the impact on the dependability and performabil- ity of the cascading or escalating failures can be analyzed. Some preliminary analysis on a case study are also shown. Acknowledgments: This work is partially supported by the EC projects 0275123 CRUTIAL and 026746 ReSIST.

Abstract
Electric Power Systems are critical infrastructures that provide vital services for the human activities; assessing their dependability is thus an high priority task. This paper presents an ad-hoc simulator for the evaluation of depend- ability and performability measures in Electrical Power System (EPS). Our stochastic model is composed by sepa- rated and simple submodels of the dynamics of the two sub- systems composing EPS: the Electrical Infrastructure and the Computer-based Control System. By providing explicit modeling of the interdependencies between the main sub- systems, the impact on the dependability and performabil- ity of the cascading or escalating failures can be analyzed. Some preliminary analysis on a case study are also shown.
