Distributed Resilient Self-Triggered Cooperative Control for Multiple Photovoltaic Generators Under Denial-of-Service Attack

This article considers the distributed resilient cooperative control for photovoltaic generators (PVs) suffered from two types of denial-of-service (DoS) attack, where the global DoS attack jams all the communication channels and the distributed one jams each of the channels independently. The proposed control method realizes the fair utilization of all PVs, and restore the active power flow across certain transmission line and the voltage of the critical bus to their reference values. The self-triggered mechanism is introduced to ensure the control performance under the DoS attack and reduce the data flow in the communication network simultaneously. In addition, the parameter selection guidance for the resilient control method with fluctuation range, triggering frequency, and stabilization time is provided. The effectiveness of the theoretical result is verified by simulation.
