**ComEd – Southwire Alliance Develops Novel Fiber Optic Transmission Conductor (FOTC)

In 1999, ComEd began work with Southwire to investigate a new concept to accurately determine the thermal behavior of overhead transmission lines during operation. It is the conductor temperature that dictates the thermal rating and available clearance under a line. However, as of yet no satisfactory method has been developed that measures conductor temperature axially throughout its length as well as radially.

A novel overhead transmission conductor system that uses optical fibers as an integral part of the phase conductor has been developed by ComEd and Southwire (Patent Pending) and placed in service on the ComEd system.

Operational since February 21, 2002, the 138 kV FOTC system uses distributed temperature sensing (DTS) to measure the temperature of the optical fibers that are embedded in the conductor. DTS allows accurate temperature measurement along the entire length of the FOTC line at different locations within the conductor.

Prior to the field demo, the FOTC system was tested and characterized by the NEETRAC {see UFTO Note, 17Jan02} and Oak Ridge National Lab (ORNL). Significant discoveries on the temperature behavior of the transmission conductor under various test conditions were found. For example, the impact of wind on radial temperature drop across a conductor and the impact of solar radiation on a conductor varied significantly from IEEE Std 738 during extreme weather conditions.

Field Trial Installation: The Fiber Optic Transmission Conductor (FOTC) was installed using a special dead-end assembly and an optical insulator. The installation method was the same as a conventional one, except that special care was taken to separate and protect the optical fibers from the conductor at the dead-end location.

The graph shows an example of the temperature data that is available in real-time from the FOTC system. With the FOTC system it is a simple matter to show the temperature of any desired interval lengths of the FOTC line. [graphic: Temperature versus Time Profile of 138 kV FOTC Line]

Utilities have a need to maximize the use of their assets. FOTC provides the medium for utilities to determine the real-time thermal operating limit of a transmission conductor in the most accurate way possible. It also provides the means to transmit data or voice communications. As the utility industry continues to evolve through transmission open access, new innovations such as FOTC will help pave the way to competitive advantage.

~~~~~~~~~~~~~~~~~~

Southwire will pursue the development and commercialization of FOTC under a license from ComEd. A market study is underway, and in particular the partners want to learn more about how much FOTC can increase transmission capacity, and how utilities will judge the merits and value for use on their own systems.

Cleantech Venture Network Issues First Report (See UFTO Note, 26 Jul 2002)

The first Cleantech Investment Monitor was released last week. It reports that investments in “clean” technology companies – ranging from fuel cells to water purification systems exceeded US$500 million in the first half of 2002, more than doubling from Q1 to Q2.. It also lists company investments made during the quarter, and profiles selected companies and investors. Download (27 pages) at:

IEEE 1547 Interconnection Standard Passes Ballot

The IEEE P1547/D10 Draft Standard for Interconnecting Distributed Resources(DR) With Electric Power Systems(EPS) received 90% affirmatives in the ballot that closed September 26, 2002.

Separately, the Standards Board approved new numbers for the three new working groups. Next meeting are in San Francisco October 8-10: (see UFTO Note 09 Sep 2002)

–P1547.1 (formerly P1589) – Draft Standard for Conformance Test Procedures for Equipment Interconnecting DR with EPS
–P1547.2 (formerly P1608) – Draft Application Guide for IEEE Standard 1547 for Interconnecting DR with EPS
–P1547.3 (formerly P1614) – Draft Guide for Monitoring, Information Exchange and Control of DR Interconnected with EPS.

Army Venture Capital Fund

Clearly modeled after the CIA’s In-Q-Tel fund (http://www.in-q-tel.com/), the U.S. Army issued a Broad Agency Announcement (BAA) to solicit proposals for the operation and management of a not-for-profit, Venture Capital Corporation (VCC). The objective is to improve the business relationships between the entrepreneurial community of high technology innovators and the U.S. Army. This is expected to accelerate the transition of innovative technology into the Army by creating greater awareness on the Army’s part concerning commercial technology development and in the entrepreneurial community concerning the Army’s potential as a technology customer willing to accept innovative solutions to its requirements. The focus initially will be on companies and programs developing power and energy technology applicable to the requirements of the individual soldier.

The BAA was issued Aug 29, and the deadline for proposals was just extended from Sept 30 to Oct 15. UFTO will follow this story with great interest. (I am advising a local VC firm who plans to submit a proposal.)

New Model to Analyze Distributed Generation Power Projects

Competitive Energy Insight (CEI) in San Diego is offering a new tool for the evaluation of DG projects, based on a model they developed for utility and other large scale power plants. EconExpert-DG is a financial model for the complete before and after tax financial analysis of DG and “Inside-the-Fence” cogen projects. The model can be used to evaluate and make decisions on virtually any DG Project or Technology, allowing owners, investors, developers and equipment suppliers to better understand the economic benefits and risks of self-generation. A suite of automated sensitivity functions make it easy to evaluate how changes in current project costs or future market conditions will impact their investment decision. The model also includes many automated analysis functions and on-line help features. The User’s Manual can be downloaded from CEI’s website.

CEI’s EconExpert-LP (for Large Power) is a similar tool for Central Power Station and Merchant Power Projects.

A 30 day free trial is offered to qualified parties. CEI’s website provides additional details and can be reached at:

Sag Line Mitigator — EPRI TC proposal

UFTO has been following this story for a long time, and they’ve made tremendous progress. [Summary: SLiM reacts to increasing conductor temperature by decreasing the effective length of conductor in the span. This mitigates the natural thermal expansion experienced by the conductor during high temperature operation. The impact is to decrease line sag during such operations.] For a good overview, download this pdf file:
http://www.misolution.com/SLiM%20Story%20080302.pdf

The initial test program went very well, and now plans are underway for utility demonstrations, under an EPRI tailored collaboration project (open to members and nonmembers of EPRI). The project will evaluate the performance of SLiM on three operating transmission lines, and will provide participating utilities with first-hand information on the operational performance of this new kind of line hardware device.

Digital Hubbub – IEEE Spectrum

Here’s an article that may be useful. It’s in current issue of IEEE Spectrum, and it appears to be available to nonmembers. The accompanying article on the major players is interesting also. (Don’t miss the chart.)

Note this paragraph, buried near the end of the article:
“As cable TV companies, burglar-alarm suppliers, and even power companies negotiate for space inside digital hubs, Whatley foresees a sort of free-for-all to control a raft of functions also tied into the hub. An electric utility could, for example, manage loads more effectively, even turning off an air conditioner during peak periods. The system would also know when homeowners returned from work, so it could bring the house back to a comfortable temperature by the time they walked in the door.”

Are energy industry companies just naive bit players with their attempts to do “gateways” and smart homes? (Note their complete absence from the chart.) Or are utilities in a unique position to pull it off while media and IT giants do battle with each other?

Digital Hubbub

Companies vie to create a single device, or hub, to handle all your home entertainment needs

By Paul Wallich, Contributing Editor

It’s a set-top! It’s a home server! It’s a digital hub! Whatever you call it—a souped-up cable box or a hard-disk recorder with wings—companies know that whoever gets it right will rule the entertainment gateway to the home.

More than a half-dozen companies so far are scrambling for the billions of dollars they hope to reap by offering consumers a single machine to handle their home entertainment needs. The companies agree on what the machine should do: record, archive, and play back video and music, organize digital photo albums, and distribute digital media around the home. Where they disagree is on what shape that machine should take.

For a view of how media companies are organizing to reach the hub in your home,

The Largest Players Rule the Media Playground
By Steven M. Cherry, Senior Associate Editor

The top media companies increasingly do a lot more than create content. The 12 companies shown here deliver content via cable systems and the Internet. They also have investments in makers of personal video recorders (PVRs) and set-top boxes and suppliers of video on demand.

Consider the former Moxi Digital, builder of a personal entertainment hub that can play DVDs and CDs and can function as a PVR and a set-top box. Moxi’s investors, before Vulcan purchased it, included AOL Time Warner, Vulcan, and Scientific-Atlanta. Vulcan also owns Digeo, another hub maker, with which Moxi was merged.
see CHART:
http://www.spectrum.ieee.org/WEBONLY/publicfeature/jul02/mediaf1.html

Eight of the companies listed—AOL Time Warner, Comcast, Disney, GE, Liberty Media, Sony, Viacom, and Vulcan— were investors in ReplayTV before it was bought by SonicBlue. TiVo, an up-and-coming PVR maker, has attracted hefty investments from almost all major media companies.

IEEE 1547 Interconnection Working Group

IEEE SCC21 Working Group
(P1547 Draft Standard For Interconnection)
31 Jan -1 Feb 2002, Arlington, VA.

Held in conjunction with the DOE Distributed Power Program Review [covered in a separate UFTO Note]

Officially established by IEEE Standards and integrated into SCC21, the P1547 project was launched 4/99, and the Working Group (WG) has been on a fast track ever since to get a standard written and accepted by stakeholders in a wide-open consensus process. Relentlessly, meetings have been held 4-6 times a year, around the country.

Complete documentation of 1547 activities can be found at:
http://grouper.ieee.org/groups/scc21/1547/archives/

An excellent overview and current status as of last Oct can be found in a paper by Dick DeBlasio in the proceedings of the IEEE T&D Expo 2001 (Atlanta). [I have the pdf.]

In the last year, Draft #7 was voted on in March, and #8 by a ‘recirculation’ ballot in October. The voting showed interesting patterns; in particular utilities were divided right down the middle. Other constituencies are clearly in favor. There were two huge flurries of email among WG members debating various points, one just before the Oct ballot, and again just before this meeting. The goal now is to complete Draft #9 and to have a successful ballot on it.

Chairman Dick DeBlasio’s introductory remarks* and charge to the group outlined a key source of the problem–a long list of issues which are most likely not appropriate to deal with in a Technical Standard are nonetheless being brought up repeatedly. People with reservations about impacts on the grid, penetration levels, contractual issues, etc etc. continue, sincerely or otherwise, to raise and debate these issues in the WG. There was also a red herring over a minimum vs. maximum standard — opponents claimed that once enacted 1547 could only be made less restrictive and not more — the truth is that IEEE standards invariably undergo revision time and again, before the ink is dry. A cynic might wonder how much of this concern is sincere, how much is due to misinformation, and how much is simply raw tactics to block DG.

Another complicating factor for the 1547 effort–it is the very first case under IEEE’s newly introduced “open balloting”. This means that any IEEE member can jump in fresh to the process and cast a vote without having been involved in previous discussions. Standards committees have long endured repeat dialogues covering ground that’s been dealt with before, but ballots with anyone able to vote is much more problemmatic.

* This agenda document has the remarks which explain the approach:
http://grouper.ieee.org/groups/scc21/1547/archives/agendas/Agenda20020131Ext.pdf
* Also see the middle section of Dick’s presentation to the DPP meeting:
http://www.eren.doe.gov/distributedpower/ReviewAnnual01Pres/0102_deblasio.pdf

New Working Groups

IEEE Standard making recognizes the difference between “shall” and “should” and “may”, and produces three types of documents: Standards, Recommended Practices, and Guides, which reflect these different levels of influence. As many of the issues being piled on to 1547 are more appropriately dealt with the second or third type rather than the first, two new working groups have been established and a third has been proposed. The idea is to strip out of 1547 anything that belongs in a different document, e.g. procedures, applications guidance, safety, etc. (In sheer size, 1547 drafts began at over 500 pages; it’s been shrinking but it’s still far above a length appropriate to a IEEE Technical Standard.)

– IEEE SCC21 P1589 — Draft Standard for Conformance Tests Procedures For Equipment Interconnecting Distributed Resources With Electric Power Systems
– IEEE SCC21 P1608 — Draft Application Guide For “IEEE Draft Standard 1547 Interconnecting Distributed Resources With Electric Power Systems”
– Potential new SCC21 PAR for DR communication/control

(P1589 is also a Standard, but it separates issues of testing from the Standard itself. The numbering may be changed to 1547.1, 1547.2 and 1547.3, to reinforce the association among them.)

After DeBlasio’s opening remarks, the opening session of the WG meeting continued with presentations on the new initiatives. Each of these new working groups are recruiting members at the present time.

P1589 (1547.2) Standard on conformance testing will specify the types of tests to be done to demonstrate compliance with 1547.1, in particular at the factory producing equipment and at commissioning. (It would not deal with post-installation testing, which is a matter between business parties involved in a particular setting.) Contact Jim Daley, 973-966-2474, jdaley@asco.com

P1608 (1547.3) Guide is to facilitate use of 1547, by providing characterizations of DG technologies. The development of this document will draw on dozens of existing resources, including 1547 resource materials, the 1001 IEEE standard for storage technology done in the 80’s (and withdrawn in ’98), various state procedures, utility handbooks, and other materials from EEI and EPRI. Contact Dick Friedman, 703-356-1300, nrf@rdcnet.com

New Comm/Control (1547.3) Guide will cover equipment and systems for both remote on onsite monitoring and control of DG, supporting a wide variety of transactions among any DG stakeholders. It will include CHP and coordination with building or enterprise energy management systems. Contact Frank Goodman, 650-855-2872, fgoodman@epri.com

Back to Draft-Writing

The rest of the first session saw the start of a difficult process of reviewing Draft #8, section by section, going over suggested changes, and deciding which materials could be moved into one or the other of the new documents. It recalled the old saying about laws and sausages, with the added fun of wordsmithing by (very large) committee.

Over the next day and 1/2, significant progress was made, with lots of material removed from the Technical and Test sections and the appendices, for inclusion in 1589 and 1608. A “strawman” for Draft #9 is set for the writing committee to tackle in the next two months. (It was also announced that there will be some adds and drops to the writing committee roster.) A full WG meeting in June will, it is hoped be followed soon with the ballot.

There is a requirement at DOE for “peer review”, so we’re seeing many of these meetings throughout the year. Last fall there was one for Distributed Energy Resources Program (DER), which includes the Distributed Power Program. (This confusing bit of terminology will be cleared up soon with a name change of the latter to something more accurately reflecting the focus on integration of DR in power systems, not DR itself.) OPT is the new entity formed last year to pull together a number of activities from across EREN.

Here is the line-up of these groups on the org chart:
– DOE
– EREN — Efficiency and Renewable Energy
– OPT — Office of Power Technologies
– DER — Distributed Energy Resources Program
– DPP — Distributed Power Program [name to change]

Presentations- Introductions and Overviews

Bob Dixon, head of OPT, opened the conference, commenting that September 11 is the main driving force in Washington. Energy security is a high profile part of it, which translates into redoubled interest in DG.

Bill Williams, IEEE-USA government liaison, outlined the many bills in Congress that deal with interconnection at both the bulk and DG level. He also noted that FERC has opened a rule-making for interconnection under 20 MW. (see below).

Richard Brent, Solar Turbines, pleaded the manufacturers’ concerns about there being different policies at every utility, in every state–sometimes different within the same utility. Many of these practices are still based on utility systems and technology of long ago.

Patricia Hoffman, head of DER, commented that just as with any infrastructure, the energy system needs to advance and evolve. One of the roles of DOE is to help bring consistency.

Joe Galdo, who leads the DPP Program, explained DPP’s mission to remove barriers to DG that arise from technology and regulation. The goal is to reduce installation cost, delay and hassle. The strategy is reflected in the array of projects supported, from the IEEE 1547, to system integration, interconnection and control, to institutional and regulatory barriers. A list of subcontracts awarded to date appears at:

Presentations – Technical Interconnection Standards and Testing

— First up, Dick DeBlasio gave an update on IEEE 1547. See separate UFTO Note on the Working Group meeting.

— Murray Davis of Detroit Edison reported on a study of penetration limits for DG on a distribution feeder. This ranks very high on the list of concerns about widespread deployment of DG. (Davis started with a quick aside that there would be no limit if grids were isolated–he’s submitted a paper to IEEE about this.) They did detailed modeling of two actual feeders using ASPEN and the Distribution WorkStation, and then modeled the impact of various amounts of DG placed at various locations. The striking conclusion, at least for these two particular feeders and for the two variables considered, is that DG penetration (or stiffness ratio, i.e. the amount of the DG compared to the size of the feeder) had no predictive value for when problems (e.g. over/under voltage) would arise. The line length, circuit particulars, and DG device sizes were far more significant. A feeder could accommodate as much as 10 times more total DG if it comes as many small units instead of 1 big one.

— NRECA has an aggressive program to support its members to do fuel cell demonstrations, with training, handbooks, databases, and a users group. Coops view DG as “a solution, not as a problem”. Together coops represent the largest “single” utility in the country, with 34 million customers in 46 states. The handbook will be available on the DOE website in the near future, and many more resources are available only to members of NRECA.
Contact Ed Torrero, 703-907-5518, ed.torrero@nreca.org

— DUIT — Distributed Utility Integration Test – This project is to come up with a plan, including a facility, to do testing of the interaction of DG with the electric system. A key element is the selection of a site or sites for the facility. To that end, a number of sites around the country at utilities and universities were evaluated as candidates. In addition, the Nevada Test Site received particular attention, in view of the extensive inventory of pre-existing buildings and equipment. (The NTS study came up with a conceptual design of a large “pole field” to be used to simulate actual distribution feeders. Rows and rows of utility poles could be patched together to provide everything from a single 30 mile feeder to countless different configurations.) (The DER Test Facility at NREL, which evaluates performance of DG interconnection systems, became operational Dec’01)
Contact Joe Iannucci, Distributed Utility Associates, joe@dua1.com, 925-447-0604.

— Certification Lab Pilot — EPRI-PEAC’s project is to define a path to “certified grid-compatible DER”. They’re writing an accreditation plan and an interconnection handbook. The effort includes actual testing of interconnection standards. For details, see the pdf download^^^, and:

Contact: Tom Key, 865-218-8082, tkey@epri-peac.com

— UL Standard for DG – Underwriters Lab is developing a standard for testing DG equipment, combining appropriate safety requirements with interconnection requirements from IEEE 1547, to produce a DG ANSI Standard that can be used to evaluate utility interconnected DG products for both electrical safety and utility interconnection to address the needs of Electrical AHJs and Utility Interconnection Engineers. This document will be UL 1741, The Standard for Inverters, Converters and Controllers for Use In Independent Power. Contact Tim Zgonena, UL, 847-272-8800 ext. 43051, timothy.p.zgonena@us.ul.com

Presentations – Codes and Regulations

— Regulatory Policy Options for DG — The Regulatory Assistance Project (RAP) is a non profit that educates and helps state regulators with electric utility regulation. With DOE funding they’re developing a series of issue papers and prototype standards documents for states to use as templates or starting points for DG interconnection, emissions, etc. One interesting observation: RAP suggests that restructuring can actually works against DG, when wholesale markets (ISOs) don’t offer payment for demand reduction, and distribution-only companies become more susceptible to revenue loss. The website has a wealth of material. Of particular interest, policy papers on DG and Electric System reliability, cost methodologies, customer value, and “Accomodating DG in Wholesale Markets”. Particularly note the Draft of a “Model DG Emissions Rule” which is getting a lot of comment. DOE is looking for more input from industry.

Contact: Cheryl Harrington, 207-582-1135, rapmaine@aol.com

— DG and FERC – Dan Adamson has done a detailed report on FERC’s role in DG, including policy directions and numerous cases that have come up over the last 10 years or more. Expect increasing complexity and litigation. Adamson believes that FERC has the authority to assert jurisdiction over interconnection of DG no matter how small, if it involves wholesale transactions, but not retail or self-generation. Last October, FERC announced an ANOPR on generation interconnection. On 11 January, consensus drafting groups submitted a lengthy filing, with big disagreements between transmission owners and small generators. A new strawman proposal was due Feb 1. Expect a NOPR for comment soon; FERC hopes to issue a final rule later this year. Even if FERC does get jurisdiction, they don’t have the staff expertise or resources to regulate at the distribution level, and will likely look to the new RTOs do handle the details. States will still have a big role in any case. And, many bills are before Congress; how they’d interact with FERC’s efforts needs to be watched closely. (There is a case before the Supreme Court that may decide much of this issue.

A detailed report will be made available soon on the DOE/DPP website. See more information at:

[Sign up for FERC’s “intranet” to see more details. Of note–most utilities’ participants seem to be in transmission or regulatory affairs… is your DG effort in the loop?]

— Local Permitting – This presentation gives a sobering picture of the situation at the local level. There are over 44,000 independent building inspection jursidictions. It can take 10 years or more to get a new technology mentioned in codes, and even then it is up to states which vintage of a code it wants to use. (For example, Nevada still uses the 1978 Electrical Code!?) Most Fire and Building inspectors have little or no experience or understanding of hydrogen, methanol, fuel cells, etc. so developers can have a tough time. DOE is sponsoring an Education and Outreach effort, doing workshops around the country for local inspectors and state officials.

Naruc Adopts Resolution Endorsing Development of Model Interconnection Agreements and Procedures

Washington, February 13, 2002
The Board of Directors of the National Association of Regulatory Utility Commissioners (NARUC), this week at the NARUC 2002 Winter Meetings in Washington, D.C., endorsed the development of model interconnection agreement and procedures under the direction of its Committees on Electricity, Energy Resources and the Environment and Finance and Technology. Reiterating its support for open access to the nation’s electricity grid, and the importance of distributed energy resources to our energy future, NARUC noted in is resolution (attached) that:

– Coordination among the States could improve the consistency of treatment so important to the efficient integration of distributed energy resources; and

– Increased national consistency would lower entry barriers and enhance business economic efficiency, and,

– The ready availability of NARUC developed model agreements and procedures will aid in balancing those concerns; and the preparation of model interconnection agreement and procedures by NARUC could provide significant support and

– Efficiencies to those States which have yet to address the challenges of distributed energy resources, and the consideration, adaptation or adoption of such models could provide material assistance in achieving the coordination among the states called for by previous resolutions.

The DOE DPP program has previously support state commissions in their efforts to address the new challenges presented by integrating distributed generation into their energy system, and has been supporting this new initiative. The issue was timely at NARUC because of the FERC’s ongoing inquiry into developing a national rule setting forth interconnection procedures and a standard agreement for FERC jurisdictional interconnections, typically at the transmission level. Some controversy may develop where both state commissions and FERC assert jurisdiction of interconnection issues at the distribution level.

2001 IEEE T&D Expo

Atlanta, 30 Oct – 2Nov 2001

This was a large event, with over 9,000 attendees, 500 exhibitors, and 150 technical papers. Sponsored by the IEEE Power Engineering Society, it focuses strictly on T&D technology, though a number of special panel sessions dealt with big picture questions.

A great deal of information is still available online at:
http://www.ieeet-d.org/
Using the buttons on the left side, “Conference” goes to a complete program listing, and “Exposition” to the exhibitor list, complete with urls for most companies. The technical papers were published on a CD.

–Opening Session

Teddy Püttgen, PES President Elect, opened the conference with the comment that electric utilities continue to be “technology enabled” rather than “technology driven”, but that is changing. Allen Franklin, CEO of the Southern Co, explained that the spinoff of Mirant enables SoCo to focus specifically on the southeast. with its vertically integrated companies, competitive generation, and new services. He sees transmission as the hottest issue, e.g. in Congress. John Rice of GE Power sees big promise in digital networking of generation and T&D. David Stump of ABB expressed a similar vision, applying ABB’s corporate-wide “Industrial IT” strategy to the utility industry. Based on the experience in the UK, Ian Davis of National Grid talked about the need for incentives for T&D investment, efficiency and performance, leading to an emphasis on asset management. Franklin came across as a very traditional utility executive, when he dismissed fuel cells, quoting “30 years ago fuel cells were almost ready. They still are.”

–SuperSession- Deregulation

The presentions were far ranging and exhaustive, and it would take many pages to give the full flavor. Charles Stalone (former FERC commissioner) took a long time to explain the issues before Congress, to strike the right balance between free markets and protections against market power abuse. David Jermain, Anderson Consulting, gave an entertaining review of the history of California’s debacle– based on a very faulty design, state officials made it much worse once things began to unravel. (I have his powerpoint presentation which he kindly sent, along with an ok to share it selectively.) Mark Rossi (Barker, Dunn & Rossi) reviewed utility deregulation around the world. Many countries are doing it, some quite successfully, though no-one gets it right at first. Richard Tabors (Tabors, Caramanis & Assoc) discussed regulation of generators, and pointed out that price volatility is intrinsic to any commodity market–it’s the journalists who renamed it “spikes” in the case of electricity. Finally Paul Addison (SolomonSmith Barney) said that customers really care about total price, not the profits of individual players. Service penalties and bonuses are needed if there is to be any incentive for investment in T&D.

–“How to Become a 3rd World Utility”
In a panel session on T&D Reliability, Jim Burke of ABB outlined 10 steps to reducing reliability.
1. Eliminate experienced engineers; replace with young ones who won’t stay.
2. Don’t participate in standards setting.
3. Lose control over generation and transmission
4. Replace things only when they fail; keep for 50 years or more til there are no spare parts.
5. Buy on price (first cost). Don’t pay for quality.
6. Eliminate R&D
7. Reduce manpower and budgets
8. Overload equipment thus increasing failure rates.
9. Lose control over daily activities–overdo outsourcing.
10. NIMBY – no new T&D but not no growth

NEETRAC R&D Focused on Power Delivery

While at the IEEE T&D Expo last November, I had the opportunity to meet folks from the National Electric Energy Testing, Research and Applications Center, a not-for-profit at Georgia Tech which focuses exclusively on power delivery technology, including (the integration of) storage and distributed generation. (See below* for a list of services provided–clearly a very practical “nuts and bolts” approach.)

NEETRAC grew out of the R&D Center that Georgia Power transferred to Georgia Tech in 1996, with all its staff and large facilities. Since then, the program scope and constituency have been broadened. The fulltime staff now exceeds 30, in addition to faculty and students who work with them. NEETRAC has access to all kinds of expertise and facilities across the entire school. They are ISO-9001 certified.

Sometimes it’s easier to start with an explanation of what something is not. NEETRAC is not a research management organization. Work is done in-house, and almost nothing is subcontracted out. They are not a funding agency. There is no technology watch function, except as part of scoping studies at the front end of projects. As the name says, they do testing, research, and applications.

Membership includes 23 major utilities (including 3 current UFTO participants, TXU, Xcel, and Exelon) and manufacturers. This number is expected to rise to 25 this year; they will stop at 30. Most pay $105K/year (much larger companies pay more).

Half of this money goes into “baseline projects”, which are selected and overseen by the Management Board. Forty-seven such projects have already been done, for a total cost of $4.2 million — on or below budget. Each project has a technical advisory committee, which usually meets by teleconference. There is a total commitment to the idea that members are to determine project content and program direction.

The other half of the money is placed directly into individual proprietary projects for the individual members (IP is very carefully protected). There is also about $1 million/year in contract research performed for other (nonmember) clients.

A new program of “Focused Initiatives” will offer non-members the chance to participate, though at 2.5 times the member cost. The proposal for the first such Initiative will appear in July, for Cable Diagnostics. NEETRAC already is doing a lot of work (for its members only) on Cables, including a test facility with cables with known defects. Vendors are invited to test and demonstrate their equipment. There are similar programs for other components.

Sandia’s PV News: IEEE Interconnection Standard For Utility-Intertied Photovoltaic Systems Is Approved

An IEEE-sponsored working group has developed an interconnection standard that will simplify the process of interconnecting photovoltaic systems with an electric utility. Photovoltaics (PV) is a solar-electric technology that uses solid-state solar cells to convert solar energy to electric energy. Not only does this standard vastly simplify PV interconnection, but it is the first IEEE standard of its kind for allowing utility interconnections of non-utility-owned distributed generation equipment. The unique aspects of this standard include tightly-defined requirements for the interconnecting hardware that can be tested by an independent test laboratory such as Underwriters Laboratories. This removes former barriers to PV use throughout the country.

John Stevens, Sandia National Labs, chaired the working group, which included about 25 members representing the utility industry, the PV industry, PV inverter manufacturers and PV researchers. The effort was sponsored by IEEE Standards Coordinating Committee 21 (SCC21). It required a little over three years from initial announcement of the project to final approval by the IEEE Standards Board. Its value is that it provides a standard that PV interconnection hardware can be designed to, thus removing the requirement for specialized hardware for different utility jurisdictions. The standard includes very specific requirements for systems of up to 10kW, but it covers systems of all sizes. The IEEE PV interconnection standard, identified as IEEE Std 929-2000, is known informally as IEEE 929.

The standard actually applies to the PV inverter, the device that converts the PV dc energy into utility-compatible ac energy. Similar inverters are used in other distributed generation systems such as fuel cells and microturbines. Many of the requirements for interconnection that are described in IEEE 929 might also be adopted for these other technologies.

IEEE 929 provides guidance for operating voltage and frequency windows, trip times for excursions outside these windows, requirements for waveform distortion, as well as defining a non-islanding inverter. An important parallel effort was performed at Underwriters Laboratories where a test procedure, UL 1741, was written that will verify that an inverter meets the requirements of IEEE 929.

In support of the IEEE 929 process, several development projects were completed at Sandia that addressed interconnection issues. The performance of several inverters operating in parallel when a utility line is de-energized was characterized to better understand the potential for unintended operation during a utility outage (“islanding”). A control scheme was developed to assure that islanding doesn’t happen. A test was developed to allow testing of single inverters to identify the presence, or lack, of an adequate anti-islanding scheme. Several specific tests were performed at the request of some electric utilities to examine such issues as ferroresonance with inverters under fault conditions and response of inverter protection schemes to the non-sinusoidal waveforms that are sometimes associated with abnormal conditions on utility systems.

This working group was an outstanding example of people with different backgrounds working together toward a common goal — simplifying the interconnection procedure. IEEE SCC21, which is chaired by Dick DeBlasio of NREL, has sponsored numerous PV-related standards since its inception in the late 1970s.
