PROJECT DESCRIPTION
This research seeks to facilitate analysis of the reliability and survivability achieved by smart grids.  To this  end,  we have proposed  an analytical reliability  model and  a survivability analysis  method  that capture  the  effect of impairments originating  from both  physical and  cyber components,  as well as the  effect of cyber-physical  interdependencies among these components.   We investigate the  use of simulation-based fault  injection  to instantiate the  model with failure data.   We aim to categorize  and quantify  dependencies in the  smart  grid and analyze the  impact  on reliability  of introducing additional interdependencies.  A pending  case study  investigates  the  effect of physical  and  cyber improvements on overall  reliability  of the  smart  grid, and  demonstrates that flawed cyber infrastructure can  result  in lower reliability  than  that of a conventional  power grid with less advanced  control.  Additional detail on the project is available at  web.mst.edu/~sendecomp
