Operational Resilience Metrics for a Complex Electrical Network
The Electrical Distribution Network is a Critical Infrastructure which plays a primary role in citizen life. Resilience is a relevant property to be achieved as it allows the network to withstand all types of perturbations affecting its functions and allowing to provide its service with continuity. Resilience comes out from a combination of a number of specific properties related to both intrinsic network technologies and to operator’s management skills. This work reports on the results obtained by using a model for estimating Resilience applied to a real network (the electrical distribution network of the city of Roma) which accounts for most of the parameters influencing the effective resilience of the network. Results confirm that the model can appropriately handle a real network and provide valuable insights to electrical operators.
