SMART GRID TIMING SYNCHRONIZATION METHOD, SYSTEM, DEVICE AND COMPUTER READABLE STORAGE MEDIUM

A smart grid timing synchronization method, a smart grid timing synchronization system, a smart grid timing synchronization device and a computer readable storage medium are provided, which is applied to any synchronization device in a smart grid. The method includes: determining whether a clock frequency of a synchronization device is consistent with a preset fixed frequency, and if not, regulating the clock frequency of the synchronization device to be consistent with the preset fixed frequency. The synchronization device includes a communication device and a central coordinator.
