"REopt: Evaluating the Reliability of Energy Components and Systems” by Dr. Jeffrey Marqusee
The performance of backup power systems ranging from building tied emergency generators to complex microgrids depends on the reliability of the individual DERs used to provide power during a grid outage. Almost all analysis of microgrid performance today ignores the inherent reliability of the DERs. The reliability of DERs has a significant impact on a microgrid’s performance, specifically the probability of providing power to support critical electric loads during an extended outage. The National Renewable Energy Laboratory (NREL) and the Army Corps of Engineer’s Power Reliability Enhancement Program (PREP) have reviewed, analyzed, and modeled multiple large empirical DER reliability data sets. This effort provides a robust set of parameters for modeling the reliability of emergency diesel generators, natural gas engines and turbines, combined heat and power systems, solar photovoltaics, wind turbines, and energy storage systems. Furthermore, NREL has developed a computational efficient and accurate methodology for factoring realistic DER reliability into assessing the performance of a microgrid. This approach is publicly available through the latest release of NREL’s REopt tool which optimizes Integrated energy systems for cost and resilience. This webinar will review the issue of reliability and energy resilience. It will define how to quantify the reliability of different DERs and what performance can be expected. Examples will be shown of the impact of DER reliability and energy resilience. An overview of the new REopt capability will be provided.
“A Holistic Approach to DoD Base-Level Non-Tactical Vehicle Electrification” by Mr. John Halliwell (EW21-7578)
EPRI has completed a study of a holistic approach to electrification of NTVs used on DoD bases. Focus has been on developing methods to accurately catalog existing NTV populations, operational cycles, and fueling needs. The project looked at developing methodologies for assessing the NTV data quality, potential data sources for operational data, techniques to estimate NTV operations where quantitative data were lacking, and methods to translate existing fueling and operations data into electrified NTV electrical power and energy needs estimates. This presentation will focus on project results highlights.
Speaker Biographies
Dr. Jeffrey Marqusee is an emeritus at NREL and an independent consultant on energy technologies and resiliency. He previously served as a senior research advisor at NREL where he provided strategic guidance for NREL’s national security work, advised DoD’s energy technology programs, and conducted research on energy resilience, microgrids, and energy storage. Prior to joining NREL, he served as a Chief Scientist at Noblis, a nonprofit science, technology, and strategy organization. He has over 20 years of government leadership in research, technology development, and policy aimed at making the DoD a more sustainable and effective organization. At DoD, he served as the Executive Director of the Strategic Environmental Research and Development Program and the Environmental Security Technology Certification Program. Before joining DoD, Dr. Marqusee worked at the Institute for Defense Analyses, Stanford University, the University of California, and the National Institute of Standards and Technology. He received a bachelor’s degree in chemistry from Cornell and a doctoral degree in physical chemistry from the Massachusetts Institute of Technology.
Mr. John Halliwell is a Senior Technical Executive and team member in the Electric Transportation Group of EPRI in Knoxville, Tennessee. John’s main area of focus is infrastructure development for plug-in electric vehicles. He joined EPRI in 2007 and has been active in the electric transportation space since 2008. Mr. Halliwell is the current co-chair of the SAE Hybrid-EV Committee, former chair of the SAE J1772 Electric Vehicle Conductive Charge Coupler Task Force, and former co-chair of the SAE AE-7D Aircraft Energy Storage and Charging Committee. His recent focus has been developing compliance and testing processes for electric vehicle charging systems. Mr. Halliwell has broad experience in design and application of electronic circuits and electronic systems in instrumentation, controls, embedded systems and power supplies. He holds bachelor’s and master’s degrees in electrical engineering from the University of Tennessee.
