A timing impairment module for electrical synchrometrology.

October 31, 2019
Author(s)
Dhananjay Anand, Marc A. Weiss, Kishan Shenoi
Accurate time is frequently cited as an enabling requirement for precisely coordinated control systems used in the electrical power system. Methods and technologies to evaluate the impact of impaired time accuracy on these control systems are frequently

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

September 25, 2019
Author(s)
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

Compositional models for power systems

September 8, 2019
Author(s)
Dhananjay Anand, Blake S. Pollard, Spencer J. Breiner, John S. Nolan, Eswaran Subrahmanian
The problem of integrating multiple overlapping models and data is pervasive in engineering, though often implicit. We consider this issue of model management in the context of the electrical power grid, as it transitions from centralized generation with

Cybersecurity Framework Smart Grid Profile

July 9, 2019
Author(s)
Jeffrey A. Marron, Avi M. Gopstein, Nadya Bartol, Larry Feldman
The Smart Grid Profile is an initial attempt to apply risk management strategies from the Framework for Improving Critical Infrastructure Cybersecurity (Cybersecurity Framework) to the smart grid. The Profile provides cybersecurity risk management guidance

A NIST Testbed for Examining the Accuracy of Smart Meters under High Harmonic Waveform Loads

May 7, 2019
Author(s)
Richard L. Steiner, Michael P. Farrell, Shannon Edwards, Thomas L. Nelson, Joni Ford, Sumaiyah Sarwat
Household and industrial electrical energy measurements are advancing into a Smart Grid stage, using solid-state watthour meters with communication capability, called Smart meters. As electrical products become heavily based on solid-state designs, such as

NIST Transactive Energy Modeling and Simulation Challenge Phase II Final Report

May 3, 2019
Author(s)
David G. Holmberg, Martin J. Burns, Steven T. Bushby, Avi Gopstein
The NIST Transactive Energy (TE) Modeling and Simulation Challenge for the Smart Grid (Challenge) spanned from 2015 to 2018. The TE Challenge was initiated to identify simulation tools and expertise that might be developed or combined in co-simulation

Using Distributed Agents to Optimize Thermal Energy Storage

March 14, 2019
Author(s)
Amanda Pertzborn
The Intelligent Building Agents Laboratory (IBAL) at the National Institute of Standards and Technology (NIST) will be used to develop and evaluate advanced control systems for commercial building heating, ventilation, and air conditioning (HVAC)

Interoperability Analysis Tool for IEC 61850-9-2 Standard-based Merging Units

February 18, 2019
Author(s)
Yuyin Song, Gerald J. FitzPatrick, Kang B. Lee, Avi M. Gopstein
Interoperability test and plugfest provide a congenial environment to test and assure interoperability of power grid devices helping to achieve equipment plug and play. However, interoperability analysis and evaluation are very time-consuming and error

Performance Assessment of Smart Meter Traffic over LTE Network Using SDR Testbed

February 18, 2019
Author(s)
Amirshahram Hematian, Wei Yu, David W. Griffith, Nada T. Golmie
In the smart grid, a variety of smart meters will be deployed to support diverse services, such as energy distribution management, grid monitoring and management, and the integration of renewable energy resources. On the power distribution side, regular

NIST Smart Grid Interoperability Test Tools

February 8, 2019
Author(s)
Dhananjay Anand, Kevin G. Brady, Yuyin Song, Cuong T. Nguyen, Kang B. Lee, Gerald J. FitzPatrick, Allen R. Goldstein, YaShian Li-Baboud
The National Institute of Standards and Technology (NIST), participated in the Universal Communication Architecture International User Group (UCAIug) Interoperability (IOP) Test Event on October 14-19, 2017 in New Orleans, Louisiana. The objective of the

A Calibration of Timing Accuracy in the NIST Cyber-Physical Systems Testbed

December 18, 2018
Author(s)
Marc A. Weiss, YaShian Li-Baboud, Dhananjay Anand, Kevin G. Brady, Paul A. Boynton, Cuong T. Nguyen, Martin J. Burns, Avi M. Gopstein
We propose a general methodology for assessing the time accuracy and uncertainties and report results from a project to calibrate timing in the NIST CPS and Smart Grid Testbeds. We measured clock synchronization accuracy and stability as well as latencies
