Abstract

There is disclosed herein methods for synchronizing clocks in power grid devices. A method performed by a clock-leader unit comprises receiving an indication of a new clock signal for a plurality of clock-follower units to follow, for use in synchronizing clocks of the plurality of clock-follower units, and sending an instruction to the plurality of clock-follower units to calibrate based on the new clock signal. The method then comprises obtaining a confirmation that the plurality of clock-follower units has completed calibration and, in response to obtaining the confirmation, sending an instruction to the clock-follower units to follow the new clock signal. By co-ordinating the transition of clock-follower units to following the new clock signal, a synchronization of time operations between the clock-follower units can be better maintained.
