Quick Take: Here are five more standards that have just been added to the IEEE's smart grid collection, which now numbers more than 100. But even more important than these current offerings is news on what IEEE plans to do next – namely, to start standardizing distribution automation terminology and protocols. As the IEEE points out "the terminology and descriptions... have previously not been standardized, which makes it difficult to develop specifications for these functions."
It is vitally important to get more DA apps in our "apps stores." This effort from IEEE should be a big help. - By Jesse Berst
The latest smart grid standards he referred to include:
· Standard for Electric Power Systems Communications – Distributed Network Protocol (DNP3): This standard specifies the DNP3 protocol structure, functions and interoperable application options for operation on communications media used in utility automation systems. It revises an earlier standard by updating protocols for dealing with and mitigating current and emerging digital cyber security threats that could affect communications systems used in smart grids and other systems, including power, water, and energy systems.
· IEEE Guide for Electric Power Distribution Reliability Indices: The guide defines distribution reliability nomenclature and indices that utilities and regulators can use to describe the reliability of distribution systems, substations, circuits and grid sections – and it defines factors that affect the calculation of the indices. It revises a previous standard in that it includes new indices that can be used now and in the future on smart grid and other distribution systems, and it updates definitions.
· IEEE Standard for Utility Industry Metering Communication Protocol Application Layer (End Device Data Tables): This standard includes common structures for encoding data that is sent over advanced metering infrastructure and smart grids. It can be used to transmit data between smart meters, home appliances, network nodes that use the IEEE 1703™ LAN/WAN messaging standard and utility enterprise collection and control systems. This standard also is a revision.
· IEEE Guide for Automatic Reclosing of Circuit Breakers for AC Distribution and Transmission Lines: Also a revision, this standard describes automatic reclosing procedures for transmission and distribution line circuit breakers, and establishes the benefits of automatic reclosing. It also addresses the considerations utilities must take into account when applying automatic reclosing technologies for proper coordination with other transmission and distribution system controls.
· Guide for Smart Distribution Applications: A standards development project more than a typical standard, this guide will categorize and describe applications that are being considered part of smart distribution system development and distribution management systems for smart grids. It will categorize applications, describe their critical functions, define their most significant components and provide examples.
The smart distribution application guide is intended to be a living document that will evolve and grow as smart distribution technologies and applications change.
