Research on FDIAs localization and traceability techniques for substation networks

Abstract

With the wide application of ubiquitous sensing， real-time communication and precise control technologies in power grids， intelligent substations are enhancing their state sensing and business decision-making capabilities. Meanwhile， the data may be invaded by cyber-attacks and become untrustworthy， thus imperiling the safe operation of power system. This paper constructs the target and method of substation fake data injection attacks （FDIAs） from the attacker's perspective. It analyzes the attack positioning， game and traceability strategy from the defender's perspective. The cyber attack and defense cases for the substation information network show that the proposed attack tracing algorithm can effectively detect the hidden attack behavior and localize and trace cyber attacks on substations.
