Abstract-- In recent years, the nature and
complexity of power grids has significantly increased, both in terms of the
interconnection of physical components and the deployment of management tools.
They have also become critically dependent on the supporting communication
infrastructure for control, monitoring, and management. The interconnected power system is thus
becoming one of the largest cyber-physical systems. These additions will add even higher orders of dimensionality
to the already large and complex power systems. This order of complexity,
intended to achieve higher levels of efficiency, flexibility and fault tolerance,
could also be a source of more failures of complex nature that can actually
degrade reliability. On the other hand, almost the entire literature on power
system reliability evaluation is concerned only with the failures of the
current-carrying part of the power grid. The literature on the
reliability of power systems examining the overlaid cyber components and their
mutual interdependence with the current carrying part is almost non-existent.
This presentation will explore the topic of the reliability assurance of cyber-physical
systems and possibly stimulate more research in this area. The current state of
reliability models will be reviewed and some ideas will be offered for creating
a framework for dealing with the power system as an interdependent cyber-physical
system. This will be illustrated by discussing the example of the design of a
substation.
