Reliable Routing Optimization for Cascaded Faults in System Protection Communication Private Network

With the rise of the energy Internet industry and the large-scale access of renewable energy to the power grid, the AC/DC hybrid grid pattern and power structure have changed profoundly, and the grid structure has become more complex. To ensure the safe, reliable, efficient and stable operation of the grid, the concept of system protection has emerged. Optimization study of reliable routing of cascading faults in system protection communication special network. This paper establishes a power network-communication network dependent network model for the impact of power grid cascading faults on the reliability of system protection dedicated network. Considering the importance of power network and communication network nodes, a reliable routing optimization method for system protection communication network cascade faults is proposed. Simulation results show that the route optimization method is effective and efficient, and it is mainly applied in the environment of system protection network cascading fault.
