چکیده :

Using communication networks and processing units in physical infrastructures has led to a new generation of systems which is known as Cyber Physical Systems (CPSs). These systems have several applications in different fields such as transportation networks, industrial control processes, water distribution systems, power systems, and etc. As it is shown in the literatures, CPSs are vulnerable to cyber-attack and physical attack in their communication channels and physical infrastructures, respectively. In this study, we will propose an observer which is used to detect false data injection attack in the turbine governor and load frequency controllers systems in the power systems. Then, a bank of attack isolation observers (AIOs) are proposed for identifying the location of the attacks in the generator buses. The numerical simulations on the IEEE 39-bus system show the feasibility and effectiveness of the proposed approach.
