Synchronization and time distribution in communication networks for time-sensitive distributed operational applications in the power grid

Modern automation applications in the power system require accurate time coherence between the constituents of the system which are increasingly distributed across the grid and still need to operate synchronously as if they were concentrated at one point. The communication network is on the other hand increasingly migrating towards packet switched and store-and-forward operation, introducing uncertainty into the behavior of the data exchange. Achieving an adequate distribution of time information across the communication network without introducing an inappropriate absolute delay remains a major task in the design of telecommunication networks for operational usage.

This working group aims to assess time distribution and frequency synchronization requirements and solutions for synchronizing power system automation applications.
