A modeling approach for dependability analysis of smart distribution grids

The distribution grids are among the most critical infrastructures which integrates advanced control and communication technologies atop of power systems. This paper presents a comprehensive modeling framework suited to study the resiliency and dependability of the next generation distribution grid. It focuses on revealing insight in the complex interaction and dependencies between the ICT based control system and the power- grid. It looks into the role of automation and new technologies in future distribution grids. The objective is through a quantitative assessment to identify vulnerabilities and to study alternative design principles and architecture of the automated distribution grids. The modeling framework is general and modular based on a stochastic activity networks using the Mobius tool. For illustration, a case study is included at the end.
