Towards an Efficient Simulation Approach for Transmission Systems with ICT Infrastructures

With the transition towards a smart grid, Information and Communications Technology (ICT) infrastructures play a growing role in the operation of transmission systems. Cyber-physical systems are usually studied using co-simulation. The latter allows to leverage existing simulators and models for both power systems and communication networks. A major drawback of co-simulation is however the computation time. Indeed, simulators have to be frequently paused in order to stay synchronised and to exchange information. This is especially true for large systems for which lots of interactions between the two domains occur. We thus propose a self-consistent simulation approach as an alternative to co-simulation. We compare the two approaches on the IEEE 39-bus test system equipped with an all-PMU state estimator. We show that our approach can reach the same accuracy as co-simulation, while using drastically less computer resources
