Grids Subcommittee
Chairman: Ernst Camm
Vice Chairman: Travis Smith
Secretary: Chris Brooks
Date: July 26, 2010
Location: IEEE PES 2010 Meeting
Minneapolis, MN, USA
Website: grouper.ieee.org/groups/td/renew/
Start Time: 1:05 PM
1. Welcome and Introductions
2. Camm reviewed the scope of subcommittee for benefit of the new attendees.
3. Minutes of New Orleans meeting were accepted.
4. Working Group (WG) reports
Mitch reviewed chief accomplishments.
Mentioned the nine papers that the group generated.
Reported the Wind Power Plant Collector Design tutorial yesterday had 55
attendees.
All presenters donated their tutorial honorariums to the IEEE Foundation:
Fund 1109 - IEEE Power & Energy Society Undergraduate Scholarship
Award Fund.
Mentioned that four new papers were under construction in the group and are
planned for submission this fall.
Encouraged attendees to join the Working Group, which will be meeting after
this meeting at 3pm.
Mentioned that the group will be renamed to add solar to the title of the group
along with wind. This name change will be officially acted on at this PES
meeting.
5. Ernst Camm introduced the first of two special speakers and their
presentations:
(1) - Keith Harley from Georgia Power, Active on the IEEE Subcommittee
managing the 1547 standard on Distributed Generation on Distribution
Systems
 (This presentation is on our renewables subcommittee website)
 Keith presented a high level overview of the current standards and
some new ones in process.
 Briefly the Titles are as follows:
1547 - IEEE 1547 Standard for Interconnecting Distributed
Resources with Electric Power Systems
1547.1 (Conformance test) - IEEE 1547.1 2005 Standard for
Conformance Tests Procedures for Equipment
Interconnecting Distributed Resources with Electric Power
Systems
1547.2 (App guide) - IEEE 1547.2 Application Guide for IEEE 1547
Standard for Interconnecting Distributed Resources with
Electric Power Systems
1547.3 (Monitoring) - IEEE 1547.3 2007 Guide For Monitoring,
Information Exchange, and Control of Distributed Resources
Interconnected with Electric Power Systems
1547.4 (Island System) - IEEE P1547.4 Draft Guide for Design,
Operation, and Integration of Distributed Resource Island
Systems with Electric Power Systems
1547.5 (Guide for >10 MVA) - IEEE P1547.5 Draft Technical
Guidelines for Interconnection of Electric Power Sources
Greater than 10MVA to the Power Transmission Grid
1547.6 (Secondary Networks) - IEEE P1547.6 Draft Recommended
Practice For Interconnecting Distributed Resources With
Electric Power Systems Distribution Secondary Networks
1547.7 (Impact studies) - IEEE P1547.7 Draft Guide to Conducting
Distribution Impact Studies for Distributed Resource
Interconnection
1547.8 (Implementation) - IEEE P1547.8 Recommended Practice
for Establishing Methods and Procedures that Provide
Supplemental Support for Implementation Strategies for
Expanded Use of IEEE Standard 1547.
 More details are in the presentation. The group handling this standard
and others is the “IEEE SCC21 group and their webpage is at:
http://grouper.ieee.org/groups/scc21/ Their full title is: SCC21
Standards Coordinating Committee on Fuel Cells, Photovoltaics,
Dispersed Generation, and Energy Storage
 (This presentation generated some discussion on some unclear
aspects of the current limits and boundaries of this and some other
standards for renewable sources and power plants. Camm asked for
this discussion to be deferred until this subcommittee meeting could
hear about the new working group that is being formed under this
subcommittee, which will have this concern as an objective.)
(2) - Modeling and Grid Integration of Dish-Stirling Solar Power Plants –
Presented by Dustin Howard and Ronald Harley
 (Presentation is on our renewables subcommittee website)
 Ronald Harley, a PhD student at Georgia Tech, reviewed the various
CSP (Concentrating Solar Power) technologies, principally –
line/trough, Fresnel rector, dish type/tower, dish Type/stirling. Power
levels ranged from 3kW to 25kW. An example Arizona plant
consumed 15 acres with 60 stirling disks for 1.5 MW and had an
estimated installed cost of about $3000/kW.
 Ronald also reviewed the operation of stirling engine and its
characteristics. He noted that its best efficiency is about 40%. This
compares to Tower CSP with about 14% efficiency.
 Grid issues were presented as nothing specific, but must meet 661-A.
 (Some informal discussion and questions followed the presentation on
the make-up of a PSCAD model of the plant and on how to deal with
stability issue for a solar plant.)
6. New WG announcement
Camm re-announce this subcommittee’s ID and PW on the IEEE website
at:
grouper.ieee.org/groups/td/renew/
All were encouraged not to share this with anyone outside of the group.
7. Discussion on proposed priority topics for new WG
Camm introduced the new WG and its Scope. Its name will be: Wind and
Solar power Plants: System Impacts and Interconnection Requirements with Tom
McDermott and Luis Vargas as Chairman and Vice-Chairman, respectively.
Scope of the new WG is attached.
Camm encouraged solar experts to please contribute to the WG and this
Subcommittee.
The new working group will first meet in Atlanta in January at the Joint
Technical Meeting and will then report to the subcommittee at next year’s PES
General Meeting in Detroit.
8. Other items - Open Discussion
Camm emphasizes that this group’s goal was to spread knowledge, then
influence standards.
Camm encourage members to go to 1547 meetings to influence it through
balloting. Another member stated that 1547.5 standard was dead that 1547.8
standard will pick it up from where 1547.5 left off.
The group expressed a need for a good general understanding of the
basic technologies and how they are different and how they are the same. Are
they current sources? What are V-I characteristics? Etc.
Group suggested a paper to compare the concerns/modeling between
wind and solar.
The group then discuss the growing confusion over meeting standards
and regulations from FERC, UL, 1547, and others for various sizes of plants and
their locations (such as on transmission vs. distribution).
The group discussed the various control requirements of a unit
and/or an entire plant by FERC, UL and IEEE. Schemes included
controlling vars, PF and/or voltage and how they vary by the size of the
plant and location.
A member commented that voltage regulation by a DG alone on a
distribution feeder could end up fighting the utility’s voltage control, such
as an LTC. It will only work if the DG is interactively and intentionally tied
in with the utility’s voltage control scheme for that feeder.
A member noted that for small renewable plants/sites the control
type was PF and if there was trouble in a unit it was to immediately drop
off the circuit. However, for large wind plants the need to immediately
drop shifted to following a LVRT template before dropping. This lead the
group to express that there is need for better guides and regulation if
renewable development is to continue to grow and flourish. Anti-islanding
capability was also mentioned as being in this mix and how and where it
should be applied.
Camm made the point that these will be the concerns of the new
working group and that the group should influence these various
regulations and standards.
9. Action items
 Establish a liaison with 1547 group done. Keith Harley will fulfill this
role.
 Please let Ernst know if there is other activity and let them know about
us, because this subcommittee is to look at the integration aspects.
10. Next meeting: JTCM (Joint Technical Committee Meeting), Atlanta, GA
January 2011.
11. Adjourned at around 3PM
