Petri net-based voltage control strategy under false data injection attack

With the increase in connectivity and automation of smart grids, the scale and complexity of them has multiplied, which increases the opportunities for cyber-attacks in smart grids. For the problems where the power system cannot be detected in time and the corresponding measures cannot be taken in time, this paper proposes a voltage control strategy based on Petri nets and event triggering mechanism. The time and probability of success of an attack can affect the assessment of its consequences. In order to understand the influence of attack on power system, the corresponding modeling method based on Petri nets is given. Adding event trigger mechanism to the voltage control strategy using on-load tap-changer can effectively control the voltage fluctuation of power system in time.
