Assessing Effects of Cyber-Attacks on Smart Grids through Power Grid and Communication Co-Simulation

The transition to renewable energy sources has led to the development of smart grids, which integrate advanced metering infrastructure and communication networks to enhance grid management. However, this evolution also introduces new cyber-attack surfaces. This paper presents a co-simulation tool designed to assess the impact of cyber-attacks on smart grids by simulating both power grid and communication components. Focusing on false data injection attacks, the tool evaluates the effects of manipulated measurement data on state estimation and grid stability. Initial results demonstrate the tool’s capability to identify vulnerabilities and inform the development of robust security measures for future smart grid control systems.
