DG Update

Has DG (distributed generation) gone quiet, or mainstream, or both?  Meanwhile, the DOE program has not done well in the proposed budget.  Congressional earmarks are taking up so much money that DOE is forced to cancel some ongoing DG applications projects.

 Here are some developments and updates.

Distributed Utility Integration Test Facility

The Distributed Utility Integration Test (DUIT) is the first full-scale, integration test of commercial-grade, utility grid interactive Distributed Energy Resources (DER) in the U.S.  DUIT addresses a key technical issue: electrical implications of operating multiple, diverse DERs at high penetration levels within a utility distribution system.  DUIT’s test plan is intended to focus on grid interaction, integration and aggregation issues, not on DER technology itself. 

After an exhaustive study of program goals and alternative sites, DOE selected the facilities at PG&E’s Modular Generation Test Facility in San Ramon, CA as the home of the new DUIT Facility.  Pre existing buildings, labs and professional staff helped make the choice, along with the adjacent test substation and high-current yard.  The site held an official opening ceremony in August 2003.

The facility offers a realistic yet controlled laboratory environment, enabling  testing of normal and abnormal operational conditions without interfering with a customer’s electric service. DG equipment at the site is commercially available and all on loan to the project from the vendors:  Inverters, rotating machinery, and generation and storage devices. DUIT provides a full-scale multi-megawatt implementation, testing and demonstration of distributed generation technologies in a realistic utility installation.

Utilities may want to take note that DUIT will be confirming and testing to the newly passed IEEE 1547 Interconnection standard, which is expected to be adopted by a large number of state regulators and legislators. Similarly, for California, DUIT will  be testing to the Rule 21 document.

To inquire about prospective DUIT project participation, technical specifications, test plans, project plans or the DUIT white paper, contact the DUIT Project Team.  Reports will be issued by CEC and other sponsors beginning this Summer, and information will be available on the DUIT website:

IEEE 1547 Update

As you know, "IEEE 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems" was approved by the IEEE Standards Board in June 2003. It was approved as an American National Standard in October 2003. (available for purchase from IEEE:      http://standards.ieee.org

SCC21 develops and coordinates new IEEE standards and maintains existing standards developed under past SCC21 projects. These include the original 1547, along with the four spinoff efforts.

> P1547.1 Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems (EPS)  (draft standard)

> P1547.2 Draft Application Guide for the IEEE 1547 Standard

> P1547.3 Monitoring, Information Exchange, and Control of Distributed Resources Interconnected with EPS (draft guide)

> P1547.4 Design, Operation, and Integration of Distributed Resource Island Systems with EPS  (draft guide)

#1 and 2 have drafts out to their working groups for review.  #1 expects to be ready for ballot early in 2005.
#3 has just completed a draft.
#4 has just been approved as a new initiative, and will be organized over the coming summer.

Complete information is available at:
   http://grouper.ieee.org/groups/scc21/wg.html

The next meeting of the IEEE 1547 series working groups will be April 20-22, 2004 in San Francisco. The P1547.1, P1547.2, and P1547.3 working groups will meet concurrently 8 a.m. to 5 p.m. each day. Working groups will be meeting separately – no plenary session is planned.  Details at:

PG&E DG Interconnection program

PG&E held a Distributed Generation (DG) Workshop last December 10. The free event provided PG&E customers and the DG community with practical information on how to navigate the various Electric Rule 21 application and interconnection review processes – from initial application through to permission to parallel with PG&E’s electric distribution system. The focus of the workshop was to communicate PG&E’s internal DG processes and interconnection technical requirements to the DG community. (For details on California’s Rule 21, see:
  http://www.energy.ca.gov/distgen/interconnection/california_requirements.html)

PG&E has set up an entire cross-company team to deal with all aspects of DG interconnection in a coordinated way.  They appear to be very committed to low hassle, low cost, minimum time for DG projects. A great deal of information about PG&E’s program, (including the 117 page powerpoint from the workshop) is available at: http://www.pge.com/gen

       ———CALIFORNIA RULE 21 ——-
CPUC:  http://www.cpuc.ca.gov/static/industry/electric/distributed+generation/index.htm
CEC:    http://www.energy.ca.gov/distgen/index.html

After passing Rule 21 in Dec 2000, California PUC established, and the CEC coordinated, a working group of all DG stakeholders. Electric Rule 21 Working Group meetings have been held about once a month since mid 2001.  The purpose is to establish procedures and work through issues to simplify and expedite interconnection projects.  (Agenda and minutes are at:
http://www.energy.ca.gov/distgen/interconnection/work_group.html)

  California Interconnection Guidebook
  Publication # 500-03-083F
  PDF file, 94 pages, 1.1 megabytes) online November 13, 2003.
  http://www.energy.ca.gov/distgen/interconnection/guide_book.html

The Guidebook is intended to help a person or project team interconnect one or more electricity generators to the local electric utility grid in California under California Rule 21. Rule 21 applies only to the three electric utilities in California that are under jurisdiction of the California PUC: PG&E, SCE, and SDG&E. The Guidebook is written as an aid to interconnection in these utility areas. It may also be useful for interconnection in some municipal utility areas with interconnection rules resembling Rule 21, principally Riverside, SMUD, and the LADWP.

IEEE 1547 Interconnection Working Group

Subject: UFTO Note – IEEE 1547 Interconnection Working Group
Date: Sat, 16 Feb 2002

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:

* Also see the middle section of Dick’s presentation to the DPP meeting:

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.
