This paper presents a load frequency control (LFC) strategy incorporating a dynamic secure event trigger mechanism (DSETM) to address the challenges posed by DoS attacks in power systems where electric vehicles (EVs) participate in frequency regulation. In the context of Vehicle-to-Grid technology, EVs-based frequency regulation is integrated into the traditional LFC framework, aiming to reduce the reliance on conventional generators and enhance system flexibility. To mitigate the adverse effects of DoS attacks and alleviate communication congestion within the system’s transmission channels, an adaptive law with an adjustable triggering threshold is proposed. This law dynamically adjusts the number of transmitted data packets based on real-time system conditions, thereby minimizing the impact of DoS attacks while optimizing communication efficiency. The proposed method is applied to a 39-bus power system, which is divided into two interconnected areas. Simulation results demonstrate that the method effectively enhances system stability and outperforms traditional low-frequency compensation techniques in terms of operational efficiency.

摘要

This paper presents a load frequency control (LFC) strategy incorporating a dynamic secure event trigger mechanism (DSETM) to address the challenges posed by DoS attacks in power systems where electric vehicles (EVs) participate in frequency regulation. In the context of Vehicle-to-Grid technology, EVs-based frequency regulation is integrated into the traditional LFC framework, aiming to reduce the reliance on conventional generators and enhance system flexibility. To mitigate the adverse effects of DoS attacks and alleviate communication congestion within the system’s transmission channels, an adaptive law with an adjustable triggering threshold is proposed. This law dynamically adjusts the number of transmitted data packets based on real-time system conditions, thereby minimizing the impact of DoS attacks while optimizing communication efficiency. The proposed method is applied to a 39-bus power system, which is divided into two interconnected areas. Simulation results demonstrate that the method effectively enhances system stability and outperforms traditional low-frequency compensation techniques in terms of operational efficiency.
