Construction and Application of SDON in the Power System based on Cyber-physical integrated model

Software-defined optical network (SDON) can provide a reliable and flexible communication network for smart grid operation, for which an SDON construction method based on the cyber-physical model is proposed. First, the collaboration of the control and data center of the optical transmission system is considered as the interdependence of the cyber-physical model, and physical and logical entities are identified In this regard, the physical fiber network relies on the operation of the control center for proper operation, while the information control network relies on the data center for the flow of control and signaling messages. Then, in order to improve the resilience of SDON control, a multi-agent communication test for the distribution networks is proposed. Simulation experiments show that the proposed SDON construction method is more resilient to transmit large amount of packets than similar methods in the static optical layer and dynamic optical layer.
