ORNL Utility Survey

Subject: UFTO Note — ORNL Utility Survey
Date: Wed, 09 Jul 1997 11:49:03 -0700
From: Ed Beardsworth

The Engineering Technology Division at Oak Ridge sent out a survey to a list of utilities recently, with a cover letter from Ed Fox, the division director. Some of you have already seen it, and I have the names of who it was sent to in your companies if you want them.

The stated purpose is to increase utility awareness of ORNL R&D, to obtain feedback on the relevance to utilities of that work, and on priorities for additional R&D. Also, they want stronger ties to utilities and potential users of ORNL work…a goal certainly congruent with UFTO!

Ed Fox can be reached at 423-574-0355, ecf@ornl.gov

The survey is being administered by:

—————————–
1.0 PLANT/EQUIPMENT DIAGNOSTICS AND CONDITION MONITORING
The following technologies provide for monitoring the condition of machinery in service, on-line diagnostics for evaluating faults, plus R&D into effects of machinery aging. The objective is to relate appropriate maintenance or replacement actions to the actual condition of the machine.

1.1 Electrical Signature Analysis (ESA)
Data characterizing electrical currents and voltage waveforms to/from motors, generators and similar devices are obtained and recorded, using non-invasive probes. ORNL-developed analysis techniques are applied to the resulting data, leading to powerful insights into the health and performance of the electrical machine and the system and/or facility in which it is installed. A typical utility application involved the evaluation of transient loads in motor operated valves at a Carolina Power & Light nuclear plant. More recent developments include improved data analysis techniques and methods for the integrated monitoring of complete systems.

Status: Early forms of ESA are being used in a range of industrial applications, including utility power plants. Licensees include B&W/Framatome and ITT Movats/Westinghouse and Public Service Electric and Gas of New Jersey. More recent developments are available for licensing and/or joint development.

Previously aware of this research: _ Yes _ No

Relevance to current needs (please circle):
(Low) 1 2 3 4 5 6 7 8 9 10 (High)

1.2 Non-Intrusive Voltage and Power Factor Monitoring
ORNL is evaluating a series of new technologies for obtaining high voltage (>480V) waveforms and power factors, without contact and without the need for potential transformers. These technologies have significant potential in power quality monitoring applications.

Status: These technologies are in an early stage of development and evaluation. They are available for licensing and/or joint development.

1.3 Check Valve Monitoring
The function and health of check valves are evaluated, using a combination of magnetic and vibration sensors. Lack of adequate function and deterioration can be detected, without the need for removal or disassembly of the component.

Status: This technology has been licensed to several service vendors, including B&W/Fram- atome and ITT Movats/Westinghouse. Consolidated Edison is also a licensee.

1.4 Improved Eddy-Current Material Defect Detection
ORNL is developing a new technology for improved defect detection and imaging in non-magnetic materials. In laboratory tests, cracks in a perforated aluminum plate, located behind a 60 mil solid aluminum plate, are clearly imaged. In addition to aircraft inspection (the initial target for this innovation), steam generator tube inspection is a potential application of this new eddy-current based technique.

Status: This technology is in the early stages of development.

1.5 Effects of Aging in Machinery
ORNL has developed a vast database and associated reports on the effects of machinery aging. Information and expertise are available on the general principles of machinery aging as well as the specific effects of aging on individual components, machines and systems.

Status: The database was developed in support of NRC investigations into the effects of aging on nuclear power stations. It is available in the form of reports at the present time. Work is ongoing to develop methodologies to support condition based maintenance decisions.

—————————–
2.0 PLANT INSTRUMENTATION & CONTROL
ORNL’s capability for conceiving, prototyping and implementing advanced instrumentation and control (I&C) capabilities extends from the I&C support of experimental work throughout the laboratory and from supplying innovative sensor and control technologies to federal agencies, utilities and private industry. The following are examples of related utility applications.

2.1 Plug-in Compatible Instrumentation and Control Upgrades
ORNL has developed and prototyped a concept in which application-specific integrated circuits (ASIC’s) mounted on a motherboard replace corresponding analog modules originally installed in utility power plants. The simplicity of the individual ASIC’s reduces concern with common mode failures, a current issue with complex software driven systems. The resulting plug-in compatible replacement modules simplify installation and operation, because rewiring is not required and because changes to operating procedures are minimized.

Status: ORNL is supporting EPRI and the Westinghouse Owner’s Group in the advancement of this technology. A prototype safety system module has been fabricated and is currently undergoing testing.

2.2 Accurate On-Line Measurement of High Temperatures
ORNL has developed a technique for continuous in-situ calibration of resistance temperature detectors. The goal is to maintain an accuracy of 0.5% (°F) under actual operating conditions and to extend the range of useful measurement from about 900°K (1200°F), at present, to 1300°K (1800°F). A typical application would be measuring steam temperatures for on-line determination of plant efficiency.

Status: The technology has been developed to a pre-commercial form and feasibility has been established through demonstrations at the Diablo Canyon and Connecticut Yankee nuclear stations, as well as tests in the Kingston Steam Plant (EPRI I&C Facility).

2.3 Solid-State Hydrogen Sensor
ORNL and EPRI are developing a small, solid state hydrogen sensor for nuclear plant containment monitoring. Other utility applications might be in conjunction with hydrogen cooled generators, battery banks, etc.

Status: The sensor is patented and available for licensing. Tests have been conducted in air, nitrogen, argon, steam and transformer oil and for H2 concentrations of 0.5% to 30%.

2.4 Automated Measurement of EMI/RFI
ORNL has developed and used an instrument to monitor and record ambient electromagnetic interference/radio frequency interference (EMI/RFI) in power stations. The system is capable of non-obtrusive, unattended operation over several-month periods.

Status: Available now for licensing or use.

—————————–
3.0 NON-LINEAR TIME-SERIES ANALYSES
The catchy but misleading name “Chaos” has often been associated with a family of advanced non-linear time-series analysis techniques. In reality, these methods allow a degree of order to be
discerned for what otherwise appear to be a series of highly random events. Examples of practical utility applications are provided below.

3.1 Improved Combustion Control
Non-linear analysis can be used to analyze and optimize fossil power plant burners, fluidized bed combustion systems and, potentially, gas turbines for higher efficiency and improved NOx control.
Status: An early application was the characterization of fluid bed combustion systems, where an objective was to avoid unstable operating regimes (e.g., chugging). More recently, the potential of this technology for improving fossil burner control is being developed through a project involving EPRI, ORNL and B&W.

3.2 Failure Prediction
There is a further potential for applying non-linear analysis to advanced machinery diagnostics/ failure prediction (e.g., in turbine-generators). Bearings, in particular, appear to exhibit chaotic behavior in advance of certain failure modes.

Status: Non-linear analysis is being evaluated in conjunction with diagnostics and condition monitoring techniques, such as electrical signature analysis (see above). Westinghouse has expressed an interest in bearing diagnostics.

—————————–
4.0 TRANSMISSION AND DISTRIBUTION

ORNL is developing technologies for automating the control of transmission systems, increasing system capacity and providing an improved understanding of the underlying costs of ancillary services.

4.1 Real-Time System Control
ORNL, DOE and EPRI are developing the technology for real-time monitoring and control of widely distributed transmission systems. This compares with current practice in which responses to disturbances are predetermined on the basis of previously completed analyses. The real-time system will employ an array of monitors, with outputs time-synchronized by satellite clocks. Artificial intelligence techniques will be used to recognize and appropriately respond to disturbances.

Status: This work is in the early stages of development.

4.2 High Capacity Transmission
ORNL has participated in R&D for increasing the capacity of high-voltage transmission lines. Included was testing of a high phase order line, which has the potential for transmitting up to three times the power of a standard single circuit AC line.

Status: The potential of this technology has been confirmed through the operation of a 1.5 mile test section, sponsored by EPRI, DOE, NYSERDA, NYSEG and ESEERCO. Given the current transition to independent operation of transmission capacity, no follow-on work has yet been identified.

4.3 Cost of Ancillary Services
One challenge in establishing the pricing basis for open access to electrical transmission systems is placing a value on ancillary services (scheduling and dispatch, load following, system protection, VARs, energy imbalance, and real power losses). Initial estimates developed by ORNL range from $1.5-$6.8/MWh, with an average of $4.1/MWh. By contrast, the FERC pro-forma schedule includes an allocation of $1/MWh for ancillary services.

Status: An initial report, based on an analysis of 12 utilities is now available. Follow-on work is recommended to establish a consistent framework for estimates.

5.0 POWER ELECTRONICS
This area includes research in power electronics, which is finding broad applicability in power quality, energy conversion and storage, adjustable speed drives, transmission, links, etc.

5.1 Resonant Snubber Inverter
The Resonant Snubber Inverter (RSI) is a power electronics innovation that employs a special resonant circuit to reduce losses during switching. Tests at ORNL have shown efficiency to be improved by 15 percentage points at half speed and 5 percentage points at rated speed. Elimination of associated voltage spikes reduces voltage stresses (leading to higher reliability), and essentially eliminates electromagnetic interference. Potential uses include power conversion for energy storage devices (e.g., flywheels, ultracapacitors, etc.) and adjustable speed drives.

Status: The RSI is currently being developed at ORNL for a number of specific applications.. The technology is available for joint development and/or licensing.

5.2 Multilevel Converter
The Multilevel Converter is another power electronics innovation that allows synthesis of high voltage waveforms, using capacitors as voltage dividers. Potential applications include DC links, static VAR generators and high voltage variable speed drives, as well as power conversion from renewable energy sources (such as photovoltaic arrays) or battery-fed systems. The ORNL technology eliminates the need for transformers, which are a significant source of cost and energy losses in conventional systems. A problem with capacitor based systems is the tendency to develop an imbalance between voltage levels when real power is being transferred (this is not a problem in static VAR generator applications). The unique contribution of ORNL is a new approach for maintaining the desired voltage balance across the capacitors, when real power is being transferred.

Status: An 11-level (21-level phase to phase) multilevel converter, employing insulated gate bipolar transistors (IGBTs) is working in the laboratory at ORNL. This system is prototypical of a 60kV multilevel converter using gate turn-off thyristors (GTOs).

—————————–
6.0 INFORMATION MANAGEMENT AND OPERATIONS ANALYSIS
This area comprises R&D on information management and operations analysis methodologies which support the management decision process.

6.1 Integrated Operational and Economic Models
ORNL has developed an extensive capability for operations and economic modeling techniques that support the management decision process. Alternative courses of action can be evaluated on a probabilistic basis, taking into account both the likelihood of various outcomes and their technical and economic consequences. Typical examples in which utilities might apply such techniques include evaluating the business potential of a new energy storage device, or determining the likelihood that a nuclear facility would be profitable over its remaining lifetime.

Status: These modeling techniques have been extensively applied. A recent example is a probabilistic assessment (for DOE) of the economic viability of each of the nuclear plants currently operating in the U.S.

6.2 Real-Time Power Scheduling
ORNL developed a “Power Advisor” to guide the operations of the Paducah, KY uranium enrichment plant in response to real-time electric power pricing inputs. The model provides a basis for deciding whether blocks of power at a given price should be accepted or whether it is more cost effective to curtail plant operations. The model includes consideration of the technical limitations of the facility, as well as the economic impact on the product bottom line.

Status: In place and operating at Paducah, KY.

6.3 Performance Indicators
The performance indicator methodology developed by ORNL is an operations management process for filtering and organizing the vast amounts of data generated in a complex management environment. The key objective is to focus management attention on activities that have the most influence on organizational goals, such as economic return, operational efficiency, safety, etc. The process starts with the selection of key performance indicators. These individual measures of performance are subjected to additional analysis and weighting, resulting in composite indices representative of overall performance, analogous to a stock market index. Feedback mechanisms are included to optimize information flow and to respond to organizational changes over time.

Status: Currently employed by DOE for managing the DOE occupational safety and health program.

—————————–
7.0 UTILITY/CUSTOMER TECHNICAL SUPPORT
The following research areas would potentially support both utility and utility customer technology support needs.

7.1 Electric Machinery Analysis
ORNL has developed an improved motor equivalent circuit model to more accurately estimate the operating characteristics of electric motors. Input to this computer-based tool can start from name plate data and increased accuracy can be obtained with supplemental calibration measurements (e.g, speed and current). Once calibrated for a given machine, the method can be used to accurately predict loads, currents, efficiency, etc. As a result, the need for additional monitoring instrumentation may be reduced in some cases.

Status: The model is complete and available through the DOE Motor Challenge Program

7.2 High Temperature Thermography
Techniques developed by ORNL offer improved capability for accurately measuring high temperatures. Using emissions from thermographic phosphors, temperatures can be measured over a wide range (cryogenic to 1600°C [2900°F]) and without the need for physical contact.

Status: This technology has been applied to several industrial processes. Initial applications have included the first stage vanes of turbine engine gas generators and the surface of steel exiting a molten zinc bath in a galvanizing process.

7.3 Electric Machinery Test Facility
ORNL has developed a flexible and well instrumented Electric Machinery Test Facility. The current capacity is 100 hp, but is now being expanded to 700 hp. During testing, loads can be varied over a wide range. Input voltage and currents can also be varied to simulate various operating demands, as well as a range of power quality situations (e.g., voltage imbalances, harmonics, etc.)

Status: The Electric Machinery Test Facility is a National User Facility available for use by private sector entities for testing and qualification of motors, generators and related components at nominal cost.

7.4 Pump Test Facility
ORNL recently commissioned a Pump Test Facility, with a design capacity of 100 hp. The configuration of the facility is highly flexible in terms of flow configuration, installed components and provisions for instrumentation and monitoring.

Status: The Pump Test Facility is a National User Facility available for use by private sector entities for testing and qualification of pumps and related components at nominal cost.

7.5 Buildings Technology Center
ORNL is actively involved in developing technologies to improve the efficiency of buildings and installed equipment. The Buildings Technology Center (BTC), established at ORNL in 1994, includes a large scale climate simulator and a hot box for testing components (walls, windows, etc.), as well as facilities for testing equipment (e.g., heating and air conditioning).

Status: The BTC is a National User Facility available for use by private sector entities for testing and qualification of building components at nominal cost.

========================================================

Secretary of Energy Advisory Board Task Force on Electric System Reliability Minutes of First Task Force Meeting January 16, 1997

J.W. Marriott Hotel Washington, D.C.

1.0 Opening Remarks and Perspectives

The first meeting of the Secretary’s Task Force on Electric System Reliability was held on January 16, 1997, in the J.W. Marriott hotel, Washington, D.C. Robert Hanfling, Chairman, Secretary of Energy Advisory Board (SEAB) opened the meeting at 8:30 am with a brief welcome to the members and an introduction of the Task Force Chairman, Philip Sharp (the Chairman).

The Chairman thanked the members for agreeing to participate on the Task Force and expressed his respect for the work they do in “keeping the lights on.” He recalled the major electrical outages in the West last summer as painful reminders of what happens when the lights do go out. He called attention to the great changes taking place now in the electric power industry (e.g., participants, demands, economic incentives) and stressed that one of the main goals of this Task Force was to make sure that reliability did not get lost in the transition. He then introduced Deputy Secretary of Energy Charles B. Curtis.

Deputy Secretary Curtis thanked the members for interrupting busy schedules and expressed his hope that the work of this panel will be useful for present and future generations. He observed that the industry is irreversibly committed to restructuring and stressed the need to assure that reliability is afforded its proper place for consideration in the evolving change. He commented that with the continued economic growth and development in our country, blackouts are debilitating to our economy and becoming even more so. The Deputy Secretary offered seven specific challenges to the Task Force:

-Although the bulk electric power system has functioned well under a sense of voluntarism, thanks largely to the North American Electric Reliability Council (NERC) and its regional councils, will voluntarism be sufficient to assure reliability under the new paradigm?

-Are federal authorities adequate and are they properly lodged in the right agencies (e.g., DOE, FERC)?

-Given the advances which have taken place in industry technology, operational procedures and training, which permit the system to be operated closer to the margins, are we asking operators to do more than is reliably possible?

-Given the evolving changes in economic incentives which underpin the industry, is the industry likely to continue to invest wisely and adequately in R&D?

-Given that the concept of an independent system operator, in one form or another, is under strong consideration in many states, is that concept necessary and sufficient for maintaining a secure and reliable system?

-Is the balance between federal/state regulations proper, and is it possible that the states could do more to assure reliability?

-Given that the 105th Congress intends to focus sharply on electricity restructuring during this session and that the Administration will likely submit legislation this year, what are the recommendations of this Task Force?

2.0 Task Force Member Introductions

Following these remarks, the Chairman asked each of the 18 present and three telecommunicating members of the Task Force to introduce themselves, briefly describe their background and describe any areas in which they felt their expertise might be especially helpful to the group.

3.0 Institutional Reliability Issues

The Chairman then introduced Mr. Michehl Gent, President, North American Electric Reliability Council (NERC), to discuss institutional reliability issues. Mr. Gent briefly described the three interconnections and noted that the regions, now numbered at ten, initially were formed by the people in each region to address the unique needs of that region. There was no intent then to make them similar since there was no thought of sending power from Minneapolis to Florida. As a result of changes, both those which have taken place already and those anticipated, the regions are becoming more alike in terms of their electric power planning and operations. He recalled events leading to the formation of NERC in 1968 after the northeast blackout of Nov. 9, 1965, and described its three primary objectives; to establish standards, measure performance, and ensure compliance. Of special note, he thought, were actions taken by NERC to adapt to evolving changes in ownership and access. By way of example, he noted that membership on the Board of Trustees had increased to 34 with representation by all segments of the industry, and also that the number of organizations with observer status had increased. Mr. Gent then introduced Don Benjamin, NERC’s Director of Operations, to discuss some of the specific activities underway within the industry to assure reliable operations in the new environment.

Mr. Benjamin highlighted a number of current initiatives, in areas of: operational security; transmission use; operating standards, interconnected operations services; and, actions to address major outages in the West last summer. He concluded with a summary statement of goals for a reliable electric system which can accommodate the marketplace by:

-operators having the “big picture” at all times; -analyzing transactions before they are consummated; -ensuring compliance with NERC policies; -establishing a program of system operator certification; and, -defining requirements for interconnected operations services.

Mr. Benjamin described in some detail NERC’s previous approach to operational security in which interconnected but nearly autonomous systems have operated through about 150 control areas established so as to be able to operate so that problems are contained within the area and do not pass beyond the boundaries. He indicated that goal is becoming more difficult to achieve on a control area basis with the increased role of market entities and open access. To supplement the control centers, the industry is moving toward security coordinators, fewer in number at twenty-two, with responsibilities to perform security analysis based on interchange schedules, coordinate emergency operations (e.g., transmission overload relief, load reductions), manage the interregional security network, and develop operating policies as may be needed. In terms of status, he advised that regional security plans are in place, coordinators exist and will have their first meeting in February, and that necessary databases are known and in preparation.

In response to a question (Cavanagh) of whether the new security system can handle tens of thousands of transactions/hour, Mr. Benjamin noted that: “We’ll have to. We probably can’t today…but we’re closer today than we were 5 years ago. With computer technology…it should be possible. Multi-regional models handle the flows and will be updated continuously. They will be able to reflect, ideally, what is really happening in the system.” Mr. Budhraja stressed the big difference between physical and financial transaction systems noting that the number of generators and points of consumption will not change, while financial transactions can number in the thousands.

The Chairman asked the status of the models NERC uses to monitor security and was informed by Mr. Benjamin that they have existed and been kept current for years. What is not in place yet is the ability of the operators to access those models in real-time. That capability is undergoing development right now. Once real-time access is possible by all operators, they can test a transaction real-time and, if it is feasible, conclude it.

4.0 Technical Reliability Issues

The Chairman then introduced Dr. Karl Stahlkopf, Vice President, Power Delivery, Electric Power Research Institute (EPRI), to discuss technical reliability issues. After a brief review of differences between design objectives for the system and the way it is being operated today, Dr. Stahlkopf moved on to discuss the causes of and lessons from last year’s major outages in the West.

After a brief background review of the record heat and unusual power flows which preceded the August 10 outage, Dr. Stahlkopf described its chronology. He then summarized the basic causes of the outage as follows:

-systems were stressed; -not enough reactive support/control in the area; -initiating conditions not studied before; -operators did not know system was insecure; -no one had the “big picture”; and, -reliability impact of maintenance not understood.

As far as lessons learned, Dr. Stahlkopf said he did not believe restructuring was a factor in the outage; rather, the system simply was stressed due to hot weather. On the other hand, he did believe that financial incentives were a factor (i.e., cheap hydro-power in Northwest); they caused flow patterns which were unusual for that time of year and, coincidently, had not been studied. Regarding lack of reactive support in the Western System Coordinating Council (WSCC) at that time, Dr. Stahlkopf noted ongoing studies by NERC and EPRI aimed at determining whether this is a chronic problem.

On the subject on maintenance impacts on reliability, Dr. Stahlkopf noted that BPA had increased their vegetation maintainance budget because of a wetter and hotter than normal growing season but questioned whether, in a competitive market, financial disincentives would exist to cause utilities to try and limit their expenditures on maintainance. Members of the Task Force agreed that this aspect must be addressed.

Dr. Stahlkopf moved on to a discussion of technology improvements that might help avoid such an occurrence in the future. He mentioned three major improvements as being Flow Actuated Control Thyristors (FACTS), Static Compensator (STATCOM), and Unified Power Flow Controller and summarized the likely contributions to reliability of each. One member of the Task Force (Budhraja) commented that all of these devices contribute to getting more out of the installed system and observed the obvious reliability implications. He questioned whether the industry should also be thinking about adding to transmission systems so they don’t have to be operated so close to their limit.

After brief discussions of the Wide Area Measuring System (WAMS), an operations data system, and several EPRI initiatives targeted on maintenance, Dr. Stahlkopf concluded that near-term technologies may improve reliability in four areas: operating tools; transmission system “agility”; monitoring and communications; and, reducing maintenance costs reliably.

5.0 State Reliability Issues

The subject of state reliability issues was addressed by the Honorable Duncan Kincheloe, Commissioner, Missouri Public Service Commission. Mr. Kincheloe said that, while states have historically engaged in regulating the power industry, can establish standards for voltage regulation, govern service priorities for restoration and curtailment, and can set standards for reserve margins, they now face prospects of diminished success in regulatory actions and need new mechanisms to look at reliability. In this regard, he suggested several areas which may warrant further consideration.

-in the area of generation and supply, he acknowledged that: past assurance of rate-based adjustments (by states) to cover investments in capacity may have undergirded utilities’ willingness to invest; and, whereas local distribution companies had responsibilities to restore service in past emergencies as a consequence of franchised territories, this may no longer apply in a competitive future.

-in the area of Federal regulation, he said: if Congress legislates retail competition, states must have authority to demand evidence of experience at providing service/reliability for new market entrants; and, if Congress legislates a (minimum) reliability standard, states would want the responsibility to assure compliance-according to historical roles- and the authority to tighten the standard, if desired.

He concluded with his opinion that states are very much in the transmission regulation business but have major concerns (with the Federal Energy Regulatory Commission (FERC)) with the issue of jurisdiction over unbundled retail power.

After the lunch break, the Chairman announced his intention to open the floor for public comment, followed by a return to member discussions on Mr. Kincheloe’s presentation.

During the public comment period, one observer rose to discuss the use of direct current on the bulk power system and noted that it is on the increase. His consulting company has been advising customers to “move away from the grid” toward more reliance on direct current and he hoped that the Task Force would consider this evolving trend in the industry.

There being no further comment by the public, the Chairman returned to discussions on Mr. Kincheloe’s presentation. During the discussion that followed, a question was raised (Holden) regarding the status of the federal/state transaction “debate. Mr. Kincheloe answered that FERC has asserted jurisdiction over certain unbundled components which heretofore had been within the purview of the states (e.g., retail transactions involving some component of the transmission system). Under the unbundling, FERC has now asserted jurisdiction.

In another area, a question was raised (Dragoumis) as to whether there have been any attempts to establish state compacts (i.e., agreements between two or more states) to set reliability rules and standards. The Chairman noted that states may propose to Congress the approval of compacts, and Congress usually approves them. The problem is that it is unlikely for states to propose compacts on very complex issues because it is so difficult for them to agree on the details.

One member (Meyer) questioned how states would be likely to handle suppliers who have, say, only one generator and whether they would require 100% reserve. While this was considered unlikely, it was also the case that the state probably wouldn’t want to impose very stringent requirements either because the suppliers would be likely to withdraw from doing business in their state….and that would affect the level of competition.

Another member (Flaim) stressed the likely need for different levels of reliability in different places but acknowledged that state-wide, regional or national reserve margins is a problem.

The experience of four years ago with the shutdown of the District of Columbia, including the Secretary of Energy’s call for industry change to avoid such events in the future for the nation’s capital, was cited by one member (Dragoumis) as an example of an action that easily might have required physical changes to the electric system outside the District. This was posed as a clear question of oversight responsibilities and a need for proper incentives.

6.0 Task Force Work Plan Development

In response to the Chairman’s request for specific suggestions of issues to be considered by the Task Force, the members identified and discussed the following:

-Vikram Budhraja noted that, while the system is comprised of generation, transmission and distribution components, 80-90% of the disruptions take place on distribution systems but 70-90% of the expenses are directed to the transmission system. He said that problems on the interconnected grid are simply unacceptable but acknowledged that those issues involve jurisdictional questions.

-Rich Sedano said he believed that generation may need to be parsed into the ancillary services expected with that generation.

-Earl Nye urged the Task Force not to ignore either distribution or generation but to focus instead on the integrated, interconnected grid. He expressed his belief that the market will provide…over time but that, unfortunately this is an instantaneous business. No one expects 100% reliable power everywhere all the time.

-Jose Delgado noted that there is a definite time dimension to the issue of reliability and questioned whether an ISO will have to balance generation and load…instantaneously. Load management, he thought, will be done as a result of market decisions.

-In response to a question by Mark Bonsall as to whether the ISO will be able to accomplish the load/generation balances, Vikram Budhraja stressed that a system cannot be run without doing that. The real question, he thought, involves both who will pay for the service and the consequences when the ISO does have to take action to balance the system.

-Theresa Flaim questioned whether a scoping document was needed to focus the deliberations, possibly grounded in the physical system, possibly on the basis of time. She felt the need to do a basic scoping before attempting to address issues like “what legislation is needed.” She suggested an initial attempt to define the dimensions of reliability.

-Matthew Holden questioned the group’s assumptions regarding the composition of the electric system 10 or 20 years out. That is, whether we expect to be operating under a new gee-whiz electric system, better but in many ways similar to the present system, or that we don’t know what the system of the future will look like.

-In addition to the components of generation, transmission, and distribution, Jose Delgado advised the group not to lose sight of load and institutional issues as possible factors of reliability.

-Alden Meyer suggested the use of scenario analysis to better frame the issues. He thought it would be extremely helpful to be able to advise policy-makers on the likely consequences to reliability of moves in one direction or another.

-Vikram Budhraja cautioned against the use of structural models (e.g., California, Niagara) citing a fundamental change in paradigms. Under the present system, customers have no choice. In the new environment, customers do have a choice. That is a fundamental and powerful distinction. He thought that producers will have more freedom to enter and leave the marketplace and that the electric grid is a unified network; it does not recognize individual ownership.

There being no further comments by the Task Force, the Chairman briefly summarized the accomplishments of the meeting, thanked the members for their attendance and active participation, and adjourned the meeting.

O’Leary and CEOs meeting re Reliability

Subject: UFTO Note – O’Leary and CEOs meeting re Reliability
Date: Thu, 17 Oct 1996 12:04:53 -0700

On September 7, during the EEI CEO Meeting in Chicago, there was an invitation only luncheon of DOE Secretary Hazel O’Leary and a number of utility industry CEOs. EPRI was present as well. The issue was reliability of the power system, and unconfirmed reports are that basically the message was “you fix it, or DOE will”. (Echoes of 1965?)

Nothing has appeared in the press that I’ve seen, and DOE (Office of Policy) has nothing in writing to offer yet. Apparently, DOE is considering a proposal to create a new task force under the SEAB (Strategic Energy Advisory Board).

From: Ed Beardsworth

RP8501-02 “Transmission Dispatch and Congestion Mgt. System” Basically to write spec for computer applications an ISO will need for scheduling, dispatch, costing, etc.

I’d mentioned this project in passing to Graham Siegel the other day, and got more details about it today. The Draft Final Report is due in to project manager Ali Vojdani in a week or two. I don’t know when it will be published. (Please don’t call Ali and tell him I told you!)

Funded by core, so apparently any epri member can have it.

Bernie Pasternak, AEP, was rep on utility advisory committee from Midwest ISO. All regions were represented.

UFTO TECH NUGGET

ENERGY STORAGE ASSOCIATION

The Utility Battery Group has now been renamed as the Energy Storage Association (ESA). The name change reflects a broader view to encompass flywheels, smes, and other energy storage technology. This year’s chairman is Chuck Ward of Oglethorpe Power.

The next meeting is scheduled at Amelia Island (30 miles from Jacksonville, Florida) for November 11-13, coinciding with an EPRI/Oglethorpe meeting on power quality. The technical agenda will focus on power electronics, and include a tour of th PQ2000 Battery Storage Project in Homerville GA.

You should very seriously consider joining ESA if you haven’t already, as a very effective way to keep informed and in the loop of developments in the rapidly emerging field, especially as it relates to UPS, power quality, and the prospect of real customer side storage. Currently, it is $1000 for a company membership, which also covers meeting registration fees.

The Executive Director is Jon Hurwitch, of Switch Technologies, Bethesda MD, 301-951-3231, fax 301-951-3235.

CREAM2 Test Case Free to EPRI Members

For members of the the SSOS business unit of EPRI (to be renamed GOP — Sorry, I have no idea what these initials mean) — Power Systems Research is doing the new version of EPRI’s CREAM model (renamed EPRI-PWR), and needs member utility volunteers for a free test run on your system or part of it. CREAM evaluates supply reliability of a power system, taking into account both generation and transmission outages, providing a consistent framework for analyzing transmission access and wheeling issues, establishing marginal cost prices at bus level, and analyzing tradeoffs between generation and transmission reinforcements.
