ScorePlus: An Integrated Scalable Cyber-Physical Experiment Environment for Smart Grid

Abstract—Smart Grid is a complex cyber-physical system that modernizes the traditional electric power infrastructure by sensing, control, computation and communication. Validating the functionality, security and reliability of Smart Grid applications within such a system requires the modeling and emulation of both power networks and communication networks, as well as the interactions between them. In this paper, we present the design, implementation and evaluation of an integrated scalable cyber-physical experiment environment for Smart Grid, called ScorePlus. Compared with previous related works, ScorePlus fills the gap by: 1) Creating and integrating both software emulator and hardware testbed, such that they all follow the same architecture and interface, and the same Smart Grid application program can be tested on either of them without any modification; 2) Providing remote access to the hardware testbed such that users can configure physical devices of the hardware testbed through Internet; 3) Supporting scalable distributed experiments such that multiple software emulators and hardware testbeds running at different locations are able to connect and form a larger Smart Grid system.
