摘要
未来大量数据的智能电网应用场景对通信协议提出了严格的要求。IEC 61850是关于电力系统内通信的标准，定义了支持智能电网的技术的最低要求。考虑到新的场景及其需求，支持组播通信可以满足时间限制。当前基于TCP/IP架构的网络技术在支持网络内多播方面存在局限性。ETArch (Entity Title Architecture)是一种基于SDN的网络架构，能够满足多播等需求，本文在此基础上提出ETArch- sg，以支持未来智能电网的通信需求。通过实验方法，将ETArch-SG与当前的TCP/IP体系结构进行了比较。我们的研究结果表明，与IP组播相比，ETArch-SG可以以更低的延迟配置IED，并以更好的性能通信pmu，达到IEC 61850的时间限制。
ETArch-SG - A SDN-based Architecture to Support the Communication Requirements of Future Smart Grids
The future use of smart grid scenarios with massive amounts of data poses stringent requirements to the communication protocols. IEC 61850, the standard regarding communication within power systems, defines the minimum requirements by the technology supporting smart grids. Considering the new scenarios and their requirements, support to multicast communication can fulfill the time constraints. Current networking technologies based on the TCP/IP architecture have limitations to support multicast inside the network. Based on the Entity Title Architecture (ETArch), an SDN based network architecture, capable of satisfying requirements such as multicast, this work proposes ETArch-SG to support future smart grid communication requirements. By using an experimental approach, ETArch-SG was compared to the current TCP/IP architecture. Our results demonstrate that ETArch-SG can configure IED with lower latencies and communicate PMUs with better performance when compared to IP Multicast, reaching the IEC 61850 time constraints.
