Abstract

The sophistication and age of electrical power grids throughout the world vary significantly, and they may vary within a country from area to area or electrical service provider to electrical service provider. Additionally, there is an increasing worldwide demand for building an expansive electricity infrastructure. Satisfying the demands for expansion and for upgrading aging electrical power systems, coupled with the advances in communications and information technologies, has stimulated the concept of Smart Grida broad term used to include the application of secure, two-way communications and information technology to electrical power grids. These demands have also driven policy, legislation, and regulation of power systems throughout the world. The U.S. Energy Independence and Security Act (EISA) of 2007 addresses the coordination of the development of a smart grid interoperability framework. Under EISA Section 1305, the Director of the National Institute of Standards and Technology (NIST) shall have the primary responsibility of coordinating the development of that framework, including soliciting input from private organizations, including the National Electrical Manufacturers Association and IEEE. Further, the scope of the interoperable framework shall be flexible, uniform, and technology neutral and align policy, business, and technology approaches in a manner that would enable all electric resources, including demand-side resources, to contribute to an efficient, reliable electricity network. The International Electrotechnical Commission (IEC) has similar interests in evolving their smart grid concepts and established the IEC Standardization Management Board (SMB) Strategic Group 3 (SG 3) on Smart Grid. It was established to advise the board concerning the technologies associated with the Smart Grid and to identify the needs for new international standards. Currently, there are many (national and international) standardization activities related to the development of smart grid concepts. A smart grid standardization roadmap was developed in 2010 by the IEC that is similar to the framework and roadmap developed by NIST. Standards developing organizations (e.g., IEEE)ņusing an open and balanced consensus processņare establishing standards for the Smart Grid building off of the conceptual reference models produced by NIST B17 and others.a IEEE Std 2030-2011 supports EISA, the NIST framework coordination efforts, IEC interests, and additional smart grid applications. It focuses on a systems-level approach to understanding and guidance for interoperability components of communications, power systems, and information technology platforms (see Figure a). This guide views the Smart Grid as a large, complex system of systems and provides guidance to navigate the numerous smart grid design pathways throughout the EPS, loads, and end-use applications. This interoperability standard lays the foundation for the expanding smart grid applications level shown in Figure a, which provides a platform for any number of smart grid applications, i.e., advanced metering infrastructure, plug-in electric vehicles, and other smart grid applications (N). These applications may be supported by additional IEEE 2030 standards.
