Time synchronization is the key to many Smart Grid (SG) applications for real-time operation necessary to make the Smart Grid highly robust and resilient to disturbances.

SCADA needs to monitor and react to real-time conditions of the grid.  Wide Area Measurement Systems gather data information from substations depending on precise time stamps for each measured value.

Up to the microsecond time stamp accuracy must be correlated and analysed.

IEEE 1588 power profile precision time protocol (PTP) in power system protection, control, automation and data communication is rapidly becoming a global standard for synchronizing clocks and phases through the power grid substations and energy generation facilities.
