Electric Vehicle Energy Management

The Canadian counterpart to the American National Standards Institute provides a platform for public comment on its consensus products:

CSA Group Draft Review

The platform provides an intuitive way into a draft standard and a way to comment upon it.

Today we take note of a product farther up the pipeline regarding electric vehicles.  Earlier this year the CSA Group (CSA America Standards Inc.) has given public notice of its intent to develop a new standard to be titled: CSA C22.2 Electric Vehicle Energy Management Systems.  From the ANSI New Project Initiation Notification announcement:

Project Need: CSA Group has been approached by the industry to develop standards and technical requirements for the deployment and safe operations of EVEMS within the Canadian regulatory structure and utility requirements. This project is intended to address this need and the existing gap in the standards required for the operation of EVEMS.

Stakeholders: Regulators, manufacturers, utilities, and industry associations.

With the rapidly growing penetration of Electric Vehicles (EVs), there is an increased demand to develop technology to support the efficient and safe charging of the vehicles with less impacts on the current electrical distribution infrastructure during peak charging times. In addition to managing the demand for electricity, EVs can become energy storage devices for the grid. This possibility raises the need to view EVs and related charging equipment as an Electric Vehicle Energy Management System (EVEMS). An EVEMS is a means of controlling electric vehicle supply equipment loads comprised of any of the following: a monitor(s), communications equipment, a controller(s), a timer(s) and other applicable device(s). Today there is no clear standard or guideline to help define the safe operations of an EVEMS although individual standards exist for some of the components within the EVEMS.

The announcement was filed in February 2019.   CSA Group has only filed formal notification required in ANSI’s due process requirements*.   

The project is on our watch list.  Many research universities are on the receiving end of electric vehicle research projects and also have large campus transportation fleets that are converting to electric vehicles.   Should any public review drafts be released we typically coordinate our response with the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly.

CSA Group consensus products are also on the standing agenda of our periodic Global teleconferences; open to everyone.  See our CALENDAR for the next online meeting.

National Electrical Safety Code

“Malakoff” | Henri Rousseau (1898)

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus  since many campus power systems are larger than publicly regulated utilities.  Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Northeast Community College | Norfolk, Nebraska

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC.   Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle.  Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.

The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry.   We will be using this workspace as the 2022 NESC continues along its developmental path:

IEEE 2022 NESC Workspace

The next step in the NESC 2022 Edition Revision Schedule set for September-October later this year when technical committees meet to respond to public comment.   The next public commenting opportunity will begin 15 January 2021.  

The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee.  The next online meeting is shown on the top menu of the IEEE E&H website:

IEEE E&H Committee

We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences.  See our CALENDAR for the next online meeting.

Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database.   Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute.    The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system.   The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.

Microgrid Systems

“Landscape with a Farm House and Windmill” (1680) / Jacob Isaaksz van Ruisdael

We have always taken a forward-looking approach to the National Electrical Code (NEC) because there is sufficient supply of NEC instructors and inspectors and not enough subject matter experts driving user-interest ideas into it.  Today we start on the parts of the 2020 NEC that cover wiring safety for microgrid systems; a relatively new term of art that appropriates safety and sustainability concepts that have existed in electrotechnology for decades.

Turn to Part II of Article 705 Interconnected Electric Power Production Sources:

Free Access 2020 National Electrical Code

You will notice that microgrid wiring safety is a relatively small part of the much larger Article 705 Content.   There were relatively minor changes to the 2017 NEC in Section 705.50  — but a great deal of new content regarding Microgrid Interconnection Devices, load side connections, backfeeding practice and disconnecting means — as can be seen in the transcripts of Code-Making Panel 4 action:

Code‐Making Panel 4 Public Input Report (692 Pages)

Code-Making Panel 4 Public Comment Report (352 Pages)

Keep in mind that the NEC says nothing (or nearly very little, in its purpose stated in Section 90.2) about microgrid economics or the economics of any other electrical installation.  It is the claim about economic advantages of microgrids that drive education facility asset management and energy conservation units to conceive, finance, install, operate and — most of all — tell the world about them.

In previous posts we have done our level best to reduce the expectations of business and finance leaders of dramatic net energy savings with microgrids — especially on campuses with district energy systems.  Microgrids do, however, provide a power security advantage during major regional contingencies — but that advantage involves a different set of numbers.

Note also that there is no user-interest from the education facility industry — the largest non-residential building construction market in the the United States — on Panel 4.   This is not the fault of the NFPA, as we explain in our ABOUT.

Public input for the 2023 National Electrical Code is due September 10th.

We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones.  Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.

Subversion®

“Mapping the Apache Software Foundation” / An Antic Disposition

Many units on the business side of the education industry directly employ a larger software staff than all the electricians, HVAC mechanics and plumbers combined.  Software staff must continually “maintain” enterprise software to keep information flow steady, secure and interoperable with other platforms.

Software upgrade versioning is an essential part of producing that result.  At a fine-grained level, revision control is used for keeping track of incrementally different versions of information, whether or not this information is computer software.   Software action is tracked using two different software versioning schemes—internal version number that may be incremented many times in a single day, such as a revision control number, and a release version that typically changes far less often, such as semantic versioning or a project code name.

In late April 2020 the Apache Software Foundation recently released an updated version of its open source consensus product — Subversion 1.14.0-rc2 — that gets this done.  It is a pre-release; a milestone to encourage wider testing and feedback from intrepid users and maintainers.  Testing action results are reported nightly at the link below:

Subversion Nightly Tarballs

Because this consensus product is open source, stakeholders can enter and leave the community at any time.   We encourage software experts with sensitivity to cost constraints to become involved in the Apache consensus product development process.   We always encourage direct communication:

Getting Involved with Apache Subversion and the Community

We keep all software consensus products on the standing agenda of our Information & Communications (ICT) technology teleconferences.   See our CALENDAR for the next online meeting; open to everyone.

As ANSI’s United States Technical Advisory Group Leader, the International Committee on Information Technology Standards must manage review drafts originating from Geneva. The IEC develops its consensus products in relatively smaller parcels which means that public review drafts tend to be released in batches of 10 to 100 at a time. Hard to keep up with but we try; focusing on consensus products incorporated by reference into codes, standards and regulations at the state and federal level.   A broad overview of INCITS ICT standards setting activity is linked below:

INCITS Public Groups Area

From our vantage of nearly 25 years representing the education facility industry in the global standards system, INCITS ranks high on our list of accredited standards developers who do the best job seeking user-interest participation in their standards suite*.  And, like other accredited standards developers, it struggles to find them.   The global standards system has an oversupply of Producer and Conformance interests and scant participation by the User interest (See our ABOUT).

For this reason, we collaborate closely with the Institute of Electrical and Electronic Engineers, the world’s largest professional organization for the world’s most transformative technologies.  Every 12 hours our algorithm picks up commenting opportunities relevant to the business side of the education industry and redirects them to the subject matter experts in the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones.

This much said, we always encourage direct participation in INCITS standards setting activity and in its administrative role as the US TAG to ISO/IEC Joint Technical Committee 1.   CLICK HERE to get started on your own.

We meet several times a month on ICT and International standards.   See our CALENDAR for the next online meeting; open to everyone.

Operation of Electrical Installations

1893 World’s Columbian Exposition / Chicago*

The United States National Committee of the International Electrotechnical Commission (USNA/IEC) seeks new participants and, above all, a Technical Advisory Group Administrator to administer United States stakeholder participation in a new International Electrotechnical Commission (IEC) standardization project described below:

Standardization in the field of broad (general) principles of operation of electrical installations. These operating instructions are intended to ensure that all operation of and work activity on, with, or near electrical installations can be carried out safely. These are electrical installations operating at voltage levels from and including extra-low voltage up to and including high voltage.  These electrical installations are designed for the generation, transmission, conversion, distribution and use of electrical power. Some of these electrical installations are permanent and fixed, such as a distribution installation in a factory or office complex, others are temporary, such as on construction sites and others are mobile or capable of being moved either whilst energised or whilst not energised nor charged.

The US education industry has both an academic and a business reason for participating in the development of this consensus product.   Many colleges and universities have power generation and distribution facilities that are larger than many regulated utilities.  The academic side of the education industry has an interest in keeping pace with the ideas running through this product, for instructional purposes and also to compete for electrical power research projects.

Individuals who are interested in becoming a participant or the TAG Administrator are invited to contact Adelana Gladstein, Program Manager – International Policy, USNC/IEC, at agladstein@ansi.org as soon as possible.

We collaborate with the Institute of Electrical & Electronic Engineers on standardization projects like this; typically the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones.  We also maintain all IEC standardization projects on our Global teleconferences.  See our CALENDAR for the next online meeting; open to everyone.
