The Smart Grid Program develops and demonstrates smart grid measurement science advances to improve the efficiency, reliability, resilience, and sustainability of the nation’s electric grid. The Program portfolio centers on two interacting components: (1) consensus standards and protocols for smart grid interoperability; and (2) measurement science research for future grid capabilities. The former is pursued in collaboration with community organizations like the Smart Electric Power Alliance, interagency groups such as the Smart Grid Task Force, and other industrial, academic, and government sector stakeholders. The NIST Framework and Roadmap for Smart Grid Interoperability, which responds to mandates to NIST from Congress and the Administration, is continuously evolved by the Program and provides the anchor for our standards efforts. An advanced smart grid testbed provides the focus for our measurement science research work. The testbed focuses on future distribution grid operational concepts and is designed to be agile, to accommodate a wide range of experimental and testing configurations, and composable, to enable collaborative use with other testbeds across the country. The program will create partnerships with other groups at NIST to leverage the campus electrical system and other research installations as expansions of our testbed capability and will partner with external organizations such as Department of Energy National Laboratories when their experimental capabilities complement NIST’s own. The research work supports and informs the standards work and together these components enable NIST to promote the emergence of a smart grid for the nation. The NIST-wide Smart Grid Program is coordinated by the Engineering Laboratory (Smart Grid and Cyber-Physical Systems Program Office) and draws on the expertise of the Engineering, Information Technology and Physical Measurement Laboratories.
Objective: To develop and demonstrate advances in measurement science to enable integration of interoperable and secure real-time sensing, control, communications, information and power technologies, in order to increase the system efficiency, reliability, resiliency and sustainability of the nation’s electric grid.
What is the Technical Idea?
The key technical idea is the development of a standards-based reference architecture, with associated interoperability and security requirements, as the foundation for prioritizing and addressing measurement science needs for the smart grid. This architectural framework is described in detail in the NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 1.0, Release 2.0, and Release 3.0, which was published in September 2014. Release 4.0, released for public comment in FY19 and for which final publication will be completed in FY20, includes a significant update to this architectural framework that focuses on the interplay between physical and communications-based interoperability and the requirements for emerging grid architectures. The focus for this work is on changes in the distribution system.
By combining a focus on interoperability with traditional NIST expertise in measurement characterization, NIST will develop the necessary measurement science deliverables, including standards, protocols, models, test methods and research publications to ensure that the performance of the smart grid at the system, subsystem, and end-user levels can be measured, controlled, and optimized to meet interoperability, security, efficiency, reliability, resiliency and other performance requirements. To accomplish this, system-level standardized architectural concepts, data models and protocols integrated with new measurement methods and models will be characterized or developed to sense, control and optimize the smart grid’s new operational paradigm. To improve grid operations, the new technical idea is to develop the measurement science to support real-time monitoring of grid functions through multiple measurement/sensor network systems to produce actionable information for grid operators. New power electronics performance characterization will be developed to evaluate the sources and impacts of power quality distortions on the distribution grid, which will lead to new approaches to power conditioning with new functionalities to support maximize integration capacity for distributed energy resources into the distribution grid. For user-to-grid interactions, the approach will be to model the interaction of complex building systems with the grid in a holistic, integrated manner that considers system and consumer interactions and their impact on energy consumption, comfort, safety, and maintenance.
What is the Research Plan?
The smart grid research plan consists of interrelated projects to advance measurement science to enable the implementation of new smart grid functionality that: improves grid reliability and resiliency; increases asset utilization and efficiency; and enables greater use of renewable energy sources in the grid. The projects are organized into five program thrust areas. These are: a systems-level cross-cutting Measurement Science for Smart Grid System Performance research thrust; three domain-focused research thrusts: Measurement Science for Transmission and Distribution Grid Operations; Measurement Science for Distributed Energy Resources; Measurement Science for User-to-Grid Interoperation; and the Smart Grid National Coordination function within the EL Smart Grid and Cyber-Physical Systems Program Office. The three domain thrusts develop enabling measurement science for robust sensing, power management and communications and intelligence within their domains, and the overarching system-level thrust supports system-level coordination, evaluation and use of these underlying domain capabilities under grid-scale operating conditions and addressing the cross-cutting security, network communications and electromagnetic environment. The smart grid testbed provides a unifying focus and collaboration platform for the team, with a research focus on microgrids. The Smart Grid National Coordination function continues its leadership role in engaging all key stakeholders in the smart grid community to ensure NIST smart grid program deliverables meet their needs.
