Smart grid standards: progress today (and more on the way)


By: SGN Staff

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."

"IEEE is continually updating its standards and developing new standards to address the needs of utilities around the world as they integrate new technologies and upgrade their systems to meet current and future operational and service objectives for smart grids," according to Bill Ash, strategic program manager for the IEEE Standards Association. "These latest IEEE standards activities underscore the importance for new standards to support the growth and evolution of the smart grid industry globally."


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.
