Abstract

Smart grids are key enablers for creating sustainable energy systems. On the other hand, they introduce a grid management challenge as power grids become more complex and dynamic. Evolving power grids towards smart grids requires combining electric energy technology with communications and information technology. In a distributed network, time synchronization is often one central question. This paper studies limitations of utilizing the widely used Network Time Protocol (NTP) in current 4G cellular networks for smart grid management. As a specific contribution, an improved, NTP based clock adjustment algorithm is proposed to provide more accurate timing information. Finally, the paper studies capabilities of emerging 5G cellular networks to further improve accuracy of timing provided to user equipment (UE).
5G网络中基于网络时间协议的智能电网测控设备定时
智能电网是创建可持续能源系统的关键推动者。另一方面,随着电网变得更加复杂和动态,它们给电网管理带来了挑战。电网向智能电网发展需要将电力能源技术与通信和信息技术相结合。在分布式网络中,时间同步通常是一个中心问题。本文研究了当前4G蜂窝网络中广泛使用的网络时间协议(Network Time Protocol, NTP)在智能电网管理中的局限性。作为一个具体的贡献,提出了一种改进的基于NTP的时钟调整算法,以提供更准确的定时信息。最后,本文研究了新兴5G蜂窝网络的能力,以进一步提高提供给用户设备(UE)的授时精度。
