MICROGRID ANTI NETWORK ATTACK STRATEGY BASED ON DIGITAL TWIN TECHNOLOGY

In order to enhance the reliability of resisting network attack, a microgrid anti network attack strategy based on Internet of things digital twin technology is proposed. The system hosted the controller and sensor to the core of the cloud plot to form the shadow of the Internet of things. The proposed digital twin technology covered the digital replication of physical layer, network layer and their hybrid interaction. In addition, it could detect false data injection and denial of service attacks on the control system. In addition, digital twin technology introduced a constructable active model to provide the interaction between defense mechanism and attack. Experimental results show that the proposed method can effectively suppress cooperative false data injection and denial of service network attacks.
