International audienceThis paper investigates system safety within a control perspective. We adopt model pre-dictive control for our safety investigation and consider a microgrid system as case study. We study the satisfaction of consumer demands under different faulty scenarios, and different controllability and observability conditions. By simulations, we show the feasibility of investigating safety in relation to control properties of the system. approach by numerical simulation to show and investigate the role and effects of observability and controllability properties on system safety

AbstractIn this work, we propose a multi-perspective framework of analysis of critical infrastructures (CIs) with respect to supply service, topology and controllability. The framework enables identifying the role of CI elements and quantifying the consequences of scenarios of multiple failures, with respect to the different perspectives considered. To present the analysis framework, a benchmark network representative of a real gas transmission network across several countries of the European Union (EU) is considered. The information extracted from such analysis can help us to identify the critical elements and how the properties of the network are affected by failures, and to propose corresponding improvements for CIs.The findings of this paper demonstrate the interest of considering several perspectives in the analysis of CIs for providing useful information for ensuring their safe and reliable operation.
