Multi-satellite clock sources-based time synchronization for power devices is widely utilized to satisfy the requirement of high-accuracy synchronization in distribution grids. Optimal route selection is necessary to ensure small time synchronization errors to perform accurate time synchronization. In this paper, we formulate an optimization problem for accurate time synchronization of power device with multiple satellite clock sources. The objective is to minimize the cumulative sum of both local and transmission synchronization through route selection optimization. An intelligent route selection algorithm is proposed to solve it and achieve active adjustment for time-varying grid topologies. Simulation results demonstrate that the proposed algorithm has excellent performance in time synchronization error.
