False Data Injection Attacks Against State Estimation in Smart Grids: Challenges and Opportunities

Static-State Estimation has been a key function of electric power grids for almost 50 years. During that time, power system engineers have been depending on it to monitor and control power networks, optimize power flow, and perform contingency analysis. State Estimation has always been vulnerable to cyberattacks targeting the availability and integrity of the grid. Nowadays, with the rapid expansion of ICT integration into power systems towards a Smart Grid, this cybersecurity threat is even more pronounced. In order to prepare for the new cybersecurity challenges brought upon by Smart Grids, this paper serves as a concentrated summary of the research on stealth false data injection attacks against Static-State Estimation.
