Simulating the communication of commands and signals in a distribution grid

The report presents the simulation of communication scenarios involving one area control centre and a set of substations inside a distribution grid of the Electrical Power System. In such scenarios, the communication is affected by threats different from those under exam in [1, 2]; in particular, here, we consider the denial of service attack to the communication network, and the temporary internal failure of a subset of substations. The scenarios have been modeled and simulated in form of Stochastic Activity Networks (SAN); the goal is the evaluation of the impact of the threats, on the communication reliability.
