Frequency Synchronization Control of Cyber-Physical Power System Based on Pinning Synchronization Control

Based on the latest research on existing cyber-physical power system, aiming at the problem that existing frequency control strategies that take into account operational uncertainties cannot achieve overall consideration of the entire system. A pinning synchronization control method is proposed based on the backstepping sliding mode control theory and adaptive control theory in this paper. Firstly, a pinning control model with external disturbance is given. Secondly, in order to achieve the pinning synchronization control of system, the synchronization controller is designed based on the backstepping sliding mode control. Finally, considering that the boundaries of uncertainties can't be directly obtained, an adaptive backstepping sliding mode synchronization controller is designed to achieve the frequency synchronization of cyber physical power system. The simulation of IEEE30-bus and IEEE39-bus cyber-physical power system verify the correctness of the proposed method.
