Electric Power Systems (EPS) become more and more critical for our society, but evaluating dependability and performability measures of such systems is a highly chal- lenging task.

Significant dif- ficulties to analyze EPS are posed by the very high com- plexity of these infrastructures and by the tight coupling be- tween them.

Abstract
Electric Power Systems (EPS) become more and more critical for our society, but evaluating dependability and performability measures of such systems is a highly chal- lenging task. Existing EPS are composed by two complex and tightly cooperating infrastructures: the Electric Infras- tructure (EI) for the electricity generation and transporta- tion to final users, and its Computer-based Control System (CCS), introduced in addition to existing SCADA systems and devoted to control the dynamics of EI and to trigger the reconfigurations in emergency situations. Significant dif- ficulties to analyze EPS are posed by the very high com- plexity of these infrastructures and by the tight coupling be- tween them. Moreover, the complex interactions between such infrastructures make harder or just practically impos- sible both to analyze the overall system and to decompose it to focus on each single infrastructure. There is also a lack of well-established theories, models and tools support- ing them, since studies on these topics are at an early stage of development. The European project CRUTIAL1, started on January 2006, aims to improve the studies in this field, with explicit focus on interdependencies between EI and the rest of the surrounding environment, in particular CCS. CRUTIAL also addresses new networked CCS systems for the management of the electric power grid, focusing on the issues arising from connection of artefacts controlling the physical process of electricity transportation to corporate networks (intranets) and to Internet.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
