Robust Optimization Method of Communication Network to Improve Resilience of Cyber-Physical Power System
Modern power systems that rely on advanced information technologies are typical cyber-physical systems (CPSs). The cyber-physical power system (CPPS) not only has the coupling between energy flow and information flow at the business level
but also has a high-degree coupling characteristic between the physical network and the power communication network at the network topology level due to the utilization of optical fiber composite overhead ground wire (OPGW)
which has the risk of cross-space cascading failures. To improve the resilience of CPPS
an information flow correlation load index considering the cyber-physical coupling and a correlation load index of the communication network are defined based on the proposed information flow and power communication network models. Then a robust optimization method for the communication network oriented to the resilience of CPPS in extreme scenarios is proposed. The proposed method allocates critical information to reliable links at the transmission network level of communication networks
so as to improve the resilience of CPPS in the extreme scenarios. The actual example system based on Guangdong power grid of China verifies the effectiveness of the proposed method. This method has been initially applied to a prototype system for Guangdong power grid.
