Poul Heegaard/Jonas Wäfler: Towards a new Dependability Model for Smart Grids

Future smart grid services have the potential to increase the reliability of the power delivery by making use of underlying ICT services. However, including ICT may create interdependencies and introduce new possible faults and failures which may partly reduce the benefits again.

In our talk we will present our approach to modeling the interdependencies between ICT and the power grid. Our model is based on the Fault-Error-Failure model known from ICT dependability analysis and includes error propagation for ICT errors.
