Stochastic Method for Generating Residential Household Energy Models of Varying Income Level and Climate Zone for Testing Energy Fairness

September 26, 2023
Hannah Covington, Brian Woo-Shem, Chenli Wang, Thomas Roth, Cuong Nguyen, Hohyun Lee
Interest in residential energy management necessitates fairness testing of energy technology and policy developments. Considering income level is particularly important because increased utility bills put low-income households at higher risk of economic

Impact of Dynamic Prices on Distribution Grid Power Quality

August 16, 2023
David Holmberg, Thomas Roth, Farhad Omar
Dynamic price signals may provide a way to support integration of customer distributed energy resources (DER) into the electric grid and to help manage DER flexibility to support distribution system and bulk grid needs. Use of DER flexibility includes peak

Reusable Network Simulation for CPS Co-Simulations

May 9, 2023
Himanshu Neema, Harmon Nine, Thomas Roth
Cyber-Physical Systems (CPS) require seamless integration of physical and computation components through communication networks. They often contain sub-systems from different physical domains (e.g., electrical, mechanical, and electronic) that must

Comparing Economic Benefits of HVAC Control Strategies in Grid-Interactive Residential Buildings

May 1, 2023
Brian Woo-Shem, Kaleb Pattawi, Hannah Covington, Patrick McCurdy, Chenli Wang, Thomas Roth, Cuong Nguyen, Yuhong Liu, Hohyun Lee
Energy consumption in buildings continues to rise with increased deployment of energy-consuming equipment such as Heating, Ventilation, and Air Conditioning (HVAC) amid a growing world economy. Renewable energy is projected to comprise a majority of the

Integrating Multiple HLA Federations for Effective Simulation-Based Evaluations of CPS

June 28, 2022
Thomas Roth, Wenqi Guo, Chenli Wang, Himanshu Neema, Anirban Bhattacharjee
Cyber-Physical Systems (CPS) are complex systems of computational, physical, and human components integrated to achieve some function over one or more networks. The use of distributed simulation, or co-simulation, is one method often used to analyze the

Integrated Sensor Data Processing for Occupancy Detection in Residential Buildings

February 22, 2021
Chenli Wang, Jun Jiang, Thomas Roth, Cuong Nguyen, Yuhong Liu, Hohyun Lee
Based on the data from U.S. Energy Information Administration (EIA), the total annual energy consumed by buildings in the United States has increased by 325% over the past 70 years. Many commercial buildings utilize a building management system (BMS) and

The UCEF Approach to Tool Integration for HLA Co-Simulations

July 15, 2020
Thomas P. Roth, Christopher W. Lemieux, Martin J. Burns
Cyber-Physical Systems (CPS) are complex systems that require expertise from multiple domains in their design, implementation, and validation. One cost-effective technique for validation of CPS is the integration of two or more domain-specific simulators

EXPPO: EXecution Performance Profiling and Optimization for CPS Co-simulation-as-a-Service

June 10, 2020
Yogesh Barve, Himanshu Neema, Zhuangwei Kang, Hongyang Sun, Aniruddha Gokhale, Thomas Roth
A co-simulation may comprise several heterogeneous federates with diverse spatial and temporal execution characteristics. In an iterative time-stepped simulation, a federation exhibits the Bulk Synchronous Parallel (BSP) computation paradigm in which all

IEEE 1451 Smart Sensor Digital Twin Federation for IoT/CPS Research

May 6, 2019
Yuyin Song, Martin J. Burns, Abhinav Pandey, Thomas P. Roth
Cyber-physical systems (CPS) are smart systems that include engineered, interacting networks of physical and cyber components. The Institute of Electrical and Electronics Engineers (IEEE) 1451 defines a set of open, common, network-independent

UCEF 1.0.0-ALPHA Kickoff Workshop: Workshop Report

April 9, 2019
Martin J. Burns, Thomas P. Roth
This report summarizes the results of a workshop held at NIST on July 27, 2017. The goal of this workshop was to introduce participants to the newly constructed Universal CPS Environment for Federation (UCEF). Over 40 attendees were provided with the UCEF

Universal CPS Environment for Federation (UCEF)

January 16, 2018
Martin J. Burns, Thomas P. Roth, Edward R. Griffor, Paul A. Boynton, Janos Sztipanovits, Himanshu Neema
NIST, in collaboration with Vanderbilt University, has assembled an open-source tool set for designing and implementing federated, collaborative and interactive experiments with cyber- physical systems (CPS). These capabilities are used in our research on


June 28, 2017
Thomas P. Roth, Yuyin Song, Martin J. Burns, Himanshu Neema, William Emfinger, Janos Sztipanovits
Cyber-physical systems (CPS) are smart systems that consist of highly interconnected networks of physical and computational components. The tight integration of a wide range of heterogeneous components enables new functionality and quality of life
