IEEE Smart Grid is an initiative launched by IEEE to help provide expertise and guidance for individuals and organizations involved in the modernization and optimization of the power grid, better known as the "smart grid". IEEE Smart Grid encompasses an array of activities, including development of new smart grid-related standards, best practices, publications, and conferences and educational opportunities.[1]
History
IEEE's involvement in the emerging smart grid reaches back to its development of power and energy standards.[2] In 2007, the Energy Independence and Security Act (EISA) was signed into law by President George W. Bush. EISA directed that under the auspices of the US Department of Energy (US DOE), the National Institute of Standards and Technology (NIST) be tasked with the development of a framework including protocols and model standards for information management to achieve interoperability of smart grid devices and systems. In Title XIII, Section 1305(a)(2) of EISA, IEEE was named as one of the Standard Setting Organizations (SSOs) whose work would be vital in the development of standards for NIST's Smart Grid Interoperability Framework.[3] As part of the first phase of NIST's Smart Grid Interoperability Framework, 16 initial standards were offered for adoption, including three developed by IEEE: C37.118, IEEE 1547, and IEEE 1686-2007.[3]
In May 2009, IEEE announced the launch of a new smart grid effort targeted to the power engineering, communications, and information technology disciplines. The first project in this effort, titled "The IEEE Standard 2030 Guide for Smart Grid Interoperability of Energy Technology and Information Technology Operation with the Electric Power System (EPS) and End-Use Applications and Loads" (IEEE 2030) established a knowledge framework for understanding and defining smart grid interoperability of the electric power system with end use applications, setting the stage for future smart grid-related standards.[4]
In January 2010, IEEE launched the first phase of IEEE Smart Grid, a new global initiative designed to bring together the organization's broad array of resources to provide expertise and guidance for those involved in Smart Grid worldwide.[5] Later that year, IEEE published inaugural editions of two new publications, cross-discipline archival journals entitled IEEE Transactions on Smart Grid,[6] and IEEE Transactions on Sustainable Energy.[7]
Current work
IEEE's approach to the smart grid is to view it as a large "System of Systems" wherein individual smart grid domains based on the NIST Smart Grid Conceptual Model are expanded into three layers: Power and Energy, Communications, and IT/Computer. IEEE considers the Communications and IT/Computer layers to be enabling infrastructure for the Power and Energy layer.[8]
IEEE Smart Grid Portal
As part of the first phase of IEEE Smart Grid, IEEE unveiled the IEEE Smart Grid Portal in January 2010.[5] As originally designed, the site served as an online clearinghouse providing smart grid-focused news, information, commentary, videos, and event information for a broad audience including business and industry, academic, and government users, as well as consumers. The portal is also home to the initiative's monthly digest, the IEEE Smart Grid Newsletter.[9]
The IEEE Smart Grid Portal was relaunched in September 2011. The redesigned site included improved search capabilities and other new features, such as a broader selection of video interviews and Q&A's with industry experts, business leaders, and researchers. It also facilitated greater user access to approved and in-development IEEE smart grid standards and an expanded conference calendar.[10]
Standards
IEEE continues to work closely with NIST on its standards roadmap and conformance testing/certification framework[11] for the smart grid. The organization also collaborates with other global standards bodies to effectively facilitate standards coordination and to ensure the intensifying smart grid movement’s success.
There are more than 100 standards that have been approved[12] or in development[13] relating to the smart grid. Among the broad number of systems and technologies addressed by these standards are broadband over power line, cyber security, distributed energy resources, Distributed Network Protocol (DNP3), and Greenhouse gas emissions credits, among others.
