#8. Smart Grid Cyber Physical Security

The important backbone of the Smart Grid is the cyber/information infrastructure, which is primarily used to communicate with different grid components. Smart grid is a complex cyber physical system containing a numerous and variety number of sources, devices, controllers and loads. Therefore, smart grid is vulnerable to the grid related disturbances. For such a dynamic system, disturbance and intrusion detection is a paramount issue. This work presented a Simulink and Opnet based co-simulated platform to carry out a cyber-intrusion in a cyber-network for modern power systems and smart grid. The IEEE 30 bus power system model was used to demonstrate the effectiveness of the simulated testbed. The experiments were performed by considering Distrubuted Denial of Service (DDoS) and tampering the communication signal type cyber-attacks. Different disturbance situations in the considered test system were considered and the results indicated the effectiveness of the proposed co-simulated scheme.

A portion of that work was presented in The 10th Annual Cyber and Information Security Research (CISR) Conference will be held at the conference center at Oak Ridge National Laboratory and published by the ACM.
