Abstract

The coordination of various terminals in the power grid requires time consistency. If there is an error in time synchronization, it will cause time misalignment and difficulties in grid data analysis. Due to the existence of massive terminals in the power grid, the existing time synchronization technology cannot be applied to the big data scenario for multi-source grid. Mobile Edge Computing (MEC) effectively combines Internet of Things (IoT) and mobile network technologies to achieve a more flexible time distribution mechanism and more accurate edge-side time synchronization accuracy. MEC and Precision Time Protocol(PTP) are applied to time distribution for the power grid in this paper. And a high-precision time distribution mechanism based on MEC for multi-source power grid is described in this paper. Simulation results show that the time synchronization accuracy can be improved by using MEC for time distribution.

基于MEC的多源电网高精度时间分配机制研究

电网中各终端的协调需要时间一致性。如果时间同步出现误差，就会造成时间错位，给网格数据分析带来困难。由于电网中存在海量终端，现有的时间同步技术无法应用于多源电网的大数据场景。移动边缘计算(MEC)将物联网(IoT)和移动网络技术有效结合，实现更灵活的时间分配机制和更精确的边缘时间同步精度。本文将MEC和精确时间协议(PTP)应用于电网的时间分配。提出了一种基于MEC的多源电网高精度时间分配机制。仿真结果表明，采用MEC进行时间分配可以提高时间同步精度。
