Performance evaluation of a hybrid communication architecture using an operational co-simulation platform

Many protocols and communication standard appear in the Substation Automation System (SAS) world. Advanced communication standards a low the exchange of peer to peer information between primary devices in order to accomplish distributed automation application inside SAS. Evaluating the conformity of primary devices towards security and SAS architectures towards required specifications is a non trivial task. For that, we propose a co-simulation approach based on hardware and software in the loop add-on modules. An architecture combining both actual and virtual devices is simulated using this approach and dynamic scenarios are constructed for generating transaction delay performance index. Finaly, we provide an adequate explanation about the Co Simulation outcomes according to the type of real devices and the configuration of dynamic scenarios.
