Impairment Aware Spectrum Allocation Algorithms for Time Synchronization in Substation Elastic Optical Network

In many special scenarios, substations of the grid require precise time synchronization. The paper cites research that highlights the significant impact of channel launch power on OSNR value. It proposes optimizing the traditional spectrum allocation algorithm by considering various channel launch powers. This optimization aims to enhance the determinacy of the transmission path and ensure reliable time synchronization performance in the power grid. These algorithms aim to enhance the determination of the transmission path and ensure the time synchronization performance of the power grid. They achieve this by adding time stamps of transmission delay and ensuring the timely arrival of time-stamp slots, all based on deterministic network technology. Simulation results demonstrate the effectiveness of these algorithms in improving time synchronization performance in the power grid.
