IEC TR 62357-200:2015（E）适用于电力系统中的信息交换，包括但不限于变电站、控制中心、维护中心、能源管理系统、基于同步相的电网稳定系统、大容量发电、分布式发电（可再生能源）、储能、负荷管理。它解决了从Internet协议版本4（IPv4）迁移到Internet协议版本6（IPv6）时遇到的问题。它描述了迁移策略，包括对应用程序、通信堆栈、网络节点、配置、地址分配、网络安全和相关管理的影响。本技术报告考虑了IEC 61850框架中的许多协议的向后兼容性，并展示了相关概念，以及必要时从IPv4到IPv6的迁移路径。

IEC TR 62357-200:2015(E) applies to information exchange in power systems including, but not restricted to, substations, control centre, maintenance centre, energy management systems, synchrophasor-based grid stability systems, bulk energy generation, distributed energy generation (renewables), energy storage, load management. It addresses the issues encountered when migrating from Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6). It describes migration strategies, covering impact on applications, communication stack, network nodes, configuration, address allocation, cyber security and the related management. This Technical Report considers backward compatibility and show concepts as well as necessary migration paths to IPv6 from IPv4 where necessary, for a number of protocols in the IEC 61850 framework.
