Protection systems are a critical feature for the proper operation of an electric grid. Protection systems should be able to quickly detect, identify, locate, and isolate the faults within a time frame that prevents damage to grid components and reduces

An Introduction to the NIST Smart Grid Interoperability Framework

June 1, 2021
Avi Gopstein
To address changes taking place in the grid, the National Institute of Standards and Technology (NIST) published an update to its Framework and Roadmap for Smart Grid Interoperability Standards. This fourth release of the Smart Grid Framework addresses

Summary Report on NIST Smart Grid Testbeds and Collaborations Workshops

March 3, 2021
Avi Gopstein, Allen R. Goldstein, Dhananjay Anand, Paul A. Boynton
This report captures feedback from two workshops that NIST conducted to determine the challenges and opportunities in the use and design of Smart Grid Testbeds and Collaborations, which were held April 11, 2019, at the University of Tennessee, Knoxville

NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 4.0

February 18, 2021
Avi Gopstein, Cuong Nguyen, Cheyney O'Fallon, Nelson Hastings, David A. Wollman
NIST's fourth framework informing America's development of the smart grid includes updates to the Smart Grid Conceptual Model, introduces new Communication Pathways Scenarios and an Ontology for the smart grid, provides guidance on cybersecurity practices

Quantifying Operational Resilience Benefits of the Smart Grid

February 9, 2021
Cheyney O'Fallon, Avi Gopstein
Automated systems for network protection, outage management, and restoration enable utilities to maintain service continuity through network reconfiguration even when confronted with a major hurricane. We employ a reduced form approach to evaluate the

Workshop on Smart Grid Interoperability Testing and Certification

January 31, 2020
Cuong T. Nguyen, Avi M. Gopstein
New smart grid architectures, devices, systems, and applications require extensive data exchange, necessitating well-defined interfaces to transfer and translate this data across the grid. Clarifying the protocols and data performance requirements across

Economics of Interoperability in the Context of Smart Grid Architectures

December 16, 2019
Cheyney O'Fallon, Avi Gopstein
Technological change in the electric power sector has progressed rapidly and there now is need for the development and evaluation of new smart grid architectures. This special publication discusses the current conditions of the U.S. electric grid and the

A demonstration of Low Power Wide Area Networking for city-scale monitoring applications

September 25, 2019
Sebastian Barillaro, Dhananjay Anand, Avi Gopstein, Julian Barillaro
Networks of sensors are key components of an Internet of Things. This paper outlines a demonstration of a wireless technology called LoRa/LoRaWAN that may be used to network sensors over a range of several kilometers. LoRa is an example of a Low Power Wide
