US-based technology association the Institute of Electrical and Electronics Engineers (IEEE) this week released a new publication – a compendium of featured articles from recent issues of the IEEE Smart Grid Newsletter.
The magazine introduces the IEEE Smart Grid Domains and Sub-Domains created by IEEE Smart Grid members.
Each of the 32 articles in ‘Smart Grid: The Next Decade’ is categorised into its appropriate IEEE Smart Grid sub-domain.
Dr. Massoud Amin, chair of IEEE Smart Grid, chairman of Texas Reliability Entity and director/professor at the University of Minnesota, explains: “The compendium is comprised of already developed foundational intellectual property of IEEE Smart Grid with participation of all stakeholders, now categorised into highly pertinent and flexible domains that provide value to the global community.”
Smart grid domains
The IEEE Smart Grid Domains and Sub-domains were created by IEEE Smart Grid experts and built upon the National Institute of Standards and Technology (NIST) conceptual model.
The 3.0 version of the NIST smart grid standards released in September 2014 views smart grids as ‘cyber-physical systems’ – hybridized systems that combine computer-based communication, control, and command with physical equipment to yield improved performance, reliability, resiliency, and user and producer awareness.
Dr Ebrahim Vaahedi, chair of the IEEE Smart Grid Publications Committee and senior director at Open Access Technology International, said the smart grid domains and sub-domains allow smart grid contributions and activities to be combined into specific areas for better understanding of the activities and their correlations.
Mr Vaahedi said: “Introducing these IEEE Smart Grid Domains and Sub-domains provides a new and fresh way of looking at all things smart grid. It’s a categorization that has never existed anywhere in the world.”
The domains are virtually categorised for IEEE members and the global community on the relaunched web portal, which provides content from IEEE Smart Grid, as well as IEEE and IEEE Xplore.
IEEE smart grid standards
One of IEEE’s newest releases of smart grid standards was in July 2015 with the launch of a new version of IEEE 80, a Guide for Safety in AC Substation Grounding.
The guide provides new equations to determine the current capabilities of bi-metallic materials that can be used in ground grids.
A new annex presents benchmarks that compare the IEEE equations with commercially available software.
The changes defined in IEEE 80-2013/Cor 1-2015, IEEE Guide for Safety in AC Substation Grounding – Corrigendum 1 have been incorporated into IEEE 80-2013.
Richard Keil, chair of the IEEE 80 Grounding Working Group, said: “The newest changes to the guide are intended to enhance the users’ overall knowledge of ground grid design and provide more detailed information to design a ground grid that applies anywhere in the world.”
IEEE 80, initially issued in 1961, proposes safe grounding practices for the design of mainly outdoor AC substations—either conventional or gas-insulated—for electric distribution or transmission and generating plants.
In some instances, IEEE 80 methods also can be applied to grounding of indoor AC substations.
