Towards a Versatile Cyber Physical Power System Testbed: Design and Operation Experience

The present trends in the area of smartgrids indicate that future transmission and distribution systems will heavily rely on digital and on communication technologies to operate. Indeed, the power systems are evolving progressively towards what is denoted as a cyber-physical system. This transition challenges the classical approaches for experimental testing and requires the development of testing platforms for cyber-physical systems able to capture the interactions between physical components, control and monitoring software and the communication infrastructure. This paper presents general considerations and requirements for a cyber-physical testing platform for power systems. The paper provides also examples of a testing platform specifying the characteristics of the major components and a summary of the experience matured in its setup and configuration. Finally, an example of an experiment on a notional smartgrid and the related results are reported.
