Campus Outdoor Lighting
“The Starry Night” | Vincent van Gogh
The IEEE Education & Healthcare Facilities Committee has completed a chapter on recommended practice for designing, building, operating and maintaining campus exterior lighting systems in the forthcoming IEEE 3001.9 Recommended Practice for the Design of Power Systems for Supplying Commercial and Industrial Lighting Systems; a new IEEE Standards Association title inspired by, and derived from, the legacy “IEEE Red Book“. The entire IEEE Color Book suite is in the process of being replaced by the IEEE 3000 Standards Collection™ which offers faster-moving and more scaleable, guidance to campus power system designers.
Campus exterior lighting systems generally run in the 100 to 10,000 fixture range and are, arguably, the most visible characteristic of public safety infrastructure. Some major research universities have exterior lighting systems that are larger and more complex than cooperative and municipal power company lighting systems which are regulated by public service commissions.
While there has been considerable expertise in developing illumination concepts by the National Electrical Manufacturers Association, Illumination Engineering Society, the American Society of Heating and Refrigeration Engineers, the International Electrotechnical Commission and the International Commission on Illumination, none of them contribute to leading practice discovery for the actual power chain for these large scale systems on a college campus. The standard of care has been borrowed, somewhat anecdotally, from public utility community lighting system practice. These concepts need to be revisited as the emergent #SmartCampus takes shape.
Electrical power professionals who service the education and university-affiliated healthcare facility industry should communicate directly with Mike Anthony (maanthon@umich.edu) or Jim Harvey (jharvey@umich.edu). This project is also on the standing agenda of the IEEE E&H committee which meets online 4 times monthly — every other Tuesday — in European and American time zones. Login credentials are available on its draft agenda page.

Quantum Computing
Is it a fact—or have I dreamed it—that, by means of electricity,
the world of matter has become a great nerve,
vibrating thousands of miles in a breathless point of time?
—Nathaniel Hawthorne, 1851 | The House of Seven Gables

Today we break form from our normal custom of assessing conceptual movement in stabilized safety and sustainability standards for education settlements and, instead, venture into a domain that will inform nearly everything we do; and with gathering pace.
We begin with the action among the experts in the organizations listed below:
- National Institute of Standards and Technology (NIST):
- NIST’s Post-Quantum Cryptography Standardization: NIST is working on standardizing cryptographic algorithms that are secure against quantum attacks. The goal is to ensure that data remains secure even with the advent of quantum computers. This involves selecting algorithms through an open competition, which began in 2016, and is still ongoing.
- Quantum Information Program: NIST conducts research and develops standards related to quantum information science, including quantum computing, quantum communication, and quantum metrology.
- Quantum Economic Development Consortium (QED-C):
- Formed as part of the National Quantum Initiative Act, QED-C aims to enable and grow the quantum industry in the U.S. It involves various stakeholders, including industry, academic institutions, and government agencies, working together to identify and address standards and other needs to foster a robust quantum ecosystem.
- National Quantum Initiative (NQI):
- Established by the National Quantum Initiative Act in 2018, NQI coordinates efforts across multiple agencies, including NIST, the Department of Energy (DOE), and the National Science Foundation (NSF), to advance quantum information science. This includes the development of standards, infrastructure, and research to support quantum technologies.
- International Standards:
- While primarily international, organizations like the International Telecommunication Union (ITU) and the International Organization for Standardization (ISO) have working groups focusing on quantum technologies. U.S. participation in these groups helps ensure that global standards align with U.S. interests and priorities.
- Federal Agencies and Research Programs:
- The DOE, NSF, and other federal agencies fund research and development in quantum computing, which often includes aspects related to standards and best practices. For example, the DOE’s Quantum Information Science (QIS) Research Centers and NSF’s Quantum Leap Challenge Institutes.
- Industry-Led Initiatives:
- Several industry consortia and companies are actively involved in developing quantum computing standards. Organizations like the IEEE have working groups focused on quantum computing and quantum communications standards.
Overall, the U.S. approach to quantum computing standards is multifaceted, involving federal agencies, industry consortia, academic research, and participation in international standard-setting bodies.

Camilo Suarez – Wilmar Martinez
Department of Electrical Engineering KU Leuven — EnergyVille, Belgium
Ω
Abstract: This paper intends to establish an overall up-to-date review on Fast Charging methods for Battery Electric Vehicles (BEV). This study starts from basic concepts involving single battery cell charging, current and future charging standards. Then, some popular power converter topologies employed for this application are introduced, and finally a summary of the industrial solutions available on the market are presented, as well as the ongoing projects related to the extreme fast charging (XFC) network expansion. Practical insights, considering the current BEV scenario, are employed to get a better understanding of this topic. Special attention is given to the modular design approach, analyzing its advantages and some of the factors that influence the number and size of modules that conform a fast charger solution.

Abstract: With the advent of Solid State Lighting came a renewed interest in the study of flicker. Potential effects include brightness enhancement, but also discomfort, ocular fatigue, phantom and stroboscopic effects. Both IEEE and IEC developed new metrics, but at the time of writing no firm consensus has been reached. Yet previous lamp studies in the Laplace laboratory showed that various flicker phenomenon are present on different lamps, but this feature is not documented. This paper focus on flicker changes w.r.t. applied voltage. The Indonesian power grid network is indeed characterized by large voltage variations; our purpose is to detect which lamps may exhibit too elevated flicker levels during out of nominal excursion and map such behavior with other electrical characteristics.

Peeking Inside the Black-Box_ A Survey on Explainable Artificial Intelligence (XAI)
Amina Adadi & Mohammed Berrada
Ben Abdellah University Morocco
ABSTRACT: At the dawn of the fourth industrial revolution, we are witnessing a fast and widespread adoption of artificial intelligence (AI) in our daily life, which contributes to accelerating the shift towards a more algorithmic society. However, even with such unprecedented advancements, a key impediment to the use of AI-based systems is that they often lack transparency. Indeed, the black-box nature of these systems allows powerful predictions, but it cannot be directly explained. This issue has triggered a new debate on explainable AI (XAI). A research field holds substantial promise for improving trust and transparency of AI-based systems. It is recognized as the sine qua non for AI to continue making steady progress without disruption. This survey provides an entry point for interested researchers and practitioners to learn key aspects of the young and rapidly growing body of research related to XAI. Through the lens of the literature, we review the existing approaches regarding the topic, discuss trends surrounding its sphere, and present major research trajectories.

How Engineers are Strengthening the Electrical Power Grid
How does the electrical grid respond to a crisis?
If the power goes out after a thunderstorm, utility crews are on the job within hours to restore service and get the lights back on. Most electric utilities in the U.S. have a reputation for reliability and recovery from situations like this. It has been noticed as planners began thinking about increased natural disasters brought on by population migration patterns, manmade interference due to malicious cyber-attacks, and the instability brought about by adding large quantities of renewable energy.
At North Carolina State University, The Future Renewable Electric Energy Delivery and Management (FREEDOM) Systems Engineering Research Center was created through funding from the National Science Foundation in 2008 to modernize the electrical grid to accommodate sustainable energy, such as wind and solar power. The Freedom Center has been involved in developing online tools for assessing vulnerabilities to address cyber-physical security called distributed grid intelligence. The hope is that smart microgrids with sensors embedded throughout the system might be more resilient to failure and easier to bring back online and large multi-state electric grids. But the emerging smart grid, together with distributed renewable energy such as rooftop solar, presents a new set of challenges to resilience. The Smart Grid involves more distributed energy down to the home level. That kind of penetration adds a level of vulnerability to a cyber threat. Engineers will certainly have to pay attention to that as the grid gets smarter.
Designing, Installing, Operating, and Maintaining Microgrids

The National Electrical Contractors Association develops a suite of consensus standards titled National Electrical Installation Standards (NEIS) that meet the intent of the National Electrical Code (NEC); particularly where the NEC asserts that an installation be constructed in a “neat and workmanlike manner”. The scope of the original undertaking, begun in the early 1990’s with University of Michigan as an early adopter, has since expanded into operation and maintenance standards; and more recently into design, installation, operating and maintaining integrated systems such as microgrids*.
Some electrotechnology professionals struggle with the notion of a “microgrid” — a trendy term of art for an integrated system of interactive and distributed power sources that many large research universities have had for decades in their district energy plant. There are some noteworthy operational differences, however; as a trend toward local power storage accelerates and education facility leaders are under pressure to prove the they have a Smart Grid (even if they already have one). None of the #SmartCampus conceptions for expansion of microgrids into individual buildings, or regions on campuses, will ever pay for themselves we cannot operate and maintain many of them economically (when set against the operational economics of the electrical supply delivered by the university district energy plant). The university-affiliated medical research and healthcare delivery campus may be a proof-point, however.
The NECA documents are used by construction owners, specifiers, contractors and electricians to clearly illustrate the performance and workmanship standards essential for different types of electrical construction. Because the NEC is intended to be primarily a wiring safety standard, the NEIS suite is referenced throughout the National Electrical Code. Electrical shop foremen and front line electricians take note.

Because the proposed change is relatively minor editorial/grammatical change, we will not comment on it but encourage other user-interests in the education facilities industry (electric shops, engineering managers, etc.) to at least become familiar with the NECA suite of standards and to incorporate them by reference into their standard practice guides for electrical trades.

*Most seasoned electrical power professionals recognize that many large research universities with district energy systems that generate in parallel with a public utility have, for decades, operated with all the essential characteristics of a microgrid (save for the political “buzz”). On-site power storage for telecommunication and mission critical facilities have been in place for decades; so has back up on-site generation. Scaling these known sources to provide normal power to a single building, or groups of buildings, is an essential difference, however. Electrical engineering expertise and judgement is needed to determine the optimal balance between a smart distributed resource (such as a microgrid) and a central resource from an existing district energy system. An array of microgrids on a large research university campus will have a cost associated with of installing, operating and maintaining them.
