IEEE SCC21 P1547 Working Group Meeting Minutes June 26-27, 2014 (Las Vegas, NV)
“P1547 Draft Standard for Interconnection and Interoperability of
Distributed Energy Resources with Associated Electric Power Systems Interfaces”
Chair: Thomas Basso
Vice Chairs: John Berdner, Jim Daley, Babak Enayati, and Mark Siira
Secretary: Charlie Vartanian
The second meeting of the P1547 Working Group (WG) was held in Las Vegas, NV, on June 26-27, 2014.
Thursday, June 26, 2014
The attendees (Attachment A) were welcomed by Tom Basso, Chair of IEEE P1547, and later, attendees
introduced themselves and their affiliations. Attendee affiliations were about equally distributed among
utilities; manufacturers and system integrators; and consultants, test labs, government and national
labs, academia, and general interest. Tom presented the agenda for the meeting (Attachment B slide).
Dick DeBlasio, SCC21 Chair and Chair of IEEE Std 1547-2003, provided some history of 1547
development and talked about IEC consideration of adopting IEEE 1547 as an IEC standard, i.e., a duallogo IEC/IEEE standard. IEC Technical Committee 8 (TC8) was requested to review 1547-2003. Many
IEC/TC8 negative comments on 1547 cited topics that are not in the scope of 1547. IEC/TC8 did not
affirm 1547 as a standard; however, 1547 was published as an IEC Publically Available Specification—a
reference document. It was pointed out that a number of foreign national interconnection standards
are based on individual 1547 clauses and basic 1547 structure. For full revision of 1547, Dick challenged
the working group to be innovative in revising it, especially to address grid modernization with respect
to interoperability and interfaces as designated in the P1547 revised title/scope/purpose. Dick
identified that IEEE requires revision of 1547 by year 2018, but the working group should target a
shorter timeline.
Tom provided background and introductory information on going forward with P1547 full revision
(Attachment B), including building from other 1547 series and IEEE Std 2030 series
experiences/documents. Tom also introduced the P1547 Secretary, and the four P1547 Vice-Chairs
(listed above), having solid expertise ranging from the utility grid, to electricity consumer facilities, to
distributed energy resources and interconnection technologies, and across multiple functionalities
including standards development, testing, and planning and engineering customer-utility level projects.
A number of updated or new draft P1547 inputs were presented by various attendees, starting with the
revised inputs based on P1547 previous meeting (April 2014) initial inputs and feedback. The following
table identifies the subclause or topic and the onsite presenter/discussion leader. That person was not
necessarily the primary author since not all attended this June meeting. The presenters were requested
to take notes for revising the draft inputs. The Annex C identifies all the inputs received for P1547
consideration; some inputs were received prior to meeting and some received onsite. Annex C does not
identify the WG meeting discussion points for revising such inputs. Some inputs in Annex C were not
discussed at this June meeting but are included for completeness and those also need to be considered
for revision by the volunteers in their respective subgroups.
*ACTION. The onsite presenters will coordinate with their respective subgroup toward revising
draft text according to onsite discussions.

R. Walling
Summary notes (more detailed discussion notes
were captured by the presenters)
WG again debated and voted down “DER size
value”; interconnection voltage value proposed
“34 kV” (also, 46 kV) was well received, but not
definitively agreed upon.
Text on interfaces and interoperability might be
useful (e.g., as informative annex); however, it
was not clear how requirements would evolve
from the text as proposed. Definitions should
first be based on IEEE dictionary (including 1547
and 2030). (Chair’s note: Glossary would state
such pre-existing definitions, and clause 3 would
state new definitions specific to P1547.)
Categorizations proposed would need major
redrafting to prove their applicability and
usefulness.
“System-level” test specs and requirements are
still an open topic; perhaps modeling/simulation
might be as deep as P1547 would go,
5.1 – as-proposed text is not needed; add new
text if new test specs and requirements are
drafted in P1547.
New 5.2 not needed as proposed – draft text is
basically informative and much of that is already
covered in 1547.
5.3 (M. Siira) as proposed, that information
should be considered with 5.3 text by D.
Kurthakoti and D. Lovelady.
Ongoing/further discussions needed, e.g., maybe:
not dynamic model/sims?; do transient
model/sims require more than 1547 does for
harmonics?; do not specify/require hardware in
the loop and RTDS?, etc. – subgroup to pursue.
(Chair’s note: might this be included as
Interconnection system planning (maybe new
clause 4 to also include interoperability,
interfaces, modeling/simulation, and other
system-level topics, etc.)?
Ongoing/further discussions needed,

Friday, June 27, 2014
Questions and Comments from the Attendees were Solicited by Chair
 A VRT and FRT presentation by Mike Behnke was brought up by an attendee as a resource for P1547
(Behnke, June 2010 presentation to the LA PES Chapter on the topic of 1547 that included LV and UF
Ride Through curves graphed against 1547 unintentional islanding limit)
*ACTION - C. Vartanian will request Behnke’s permission to post presentation for the WG.
 International Standards information related to ride through was discussed. Such information will be
compiled (not copyrighted information from Standards themselves, but other material that
references or includes information from these standards)
*ACTION - Bob Nelson will provide information to WG Secretary to post for the WG.
 Discussion on ride through limits resulted in WG recommendation that the volunteers drafting ride
through requirements should document a more rigorous and quantified basis for the limits.
Participant commented that EPRI is working on this topic, and that EPRI’s work would be available to
P1547. Chair commented that EPRI’s work, and all other relevant inputs, should be pursued for
submittal to the WG.
P1547 Subgroup Logistics
Chair distributed a subgroup volunteer sign-up sheet for WG participants who want to actively
contribute, for them to list the clauses for which they are interested in joining a topical subgroup. Near
the end of the meeting, the signup sheet showed about 30 individuals volunteered for various
subclauses or topics.
*ACTION - Chair will compile sign-up inputs into a master list and request participants to verify
their participation, and request working group members who are not in attendance if they wish
to volunteer to actively contribute in which areas.
Subgroup operations were discussed that they should debate topics and bring draft proposals back to
full working group. The subgroups should document their key meeting/discussion information, e.g.,
schedule, agenda, attendance, and summary note of decisions and outcomes. The subgroup should
attempt to establish “their” consensus on proposed text or concepts focused on a topic, but it is
understood that alternative positions are likely. IEEE Staff, Justin Caso, would be a point of contact to
set up WEBEX’s for subgroup working sessions.
Justin Caso gave a preview of the Central Desktop website for the 1547rev WG. After the Desktop is
populated with baseline P1547 information, P1547 Chair and Secretary will provide such Desktop
background to the WG for P1547 document development.

Open Floor Discussion of P1547 Revision Consideration
Participants were invited by the Chair to bring up additional specific 1547 clause concerns or topics they
think is a revision priority, provide short rationale, and proposal or approach, if possible.
 Clause 5.4.2 Cease to energize p.15. Jim Daly expressed concern that the next-to-last sentence has
potential to create a hazardous condition. Doable in the lab, but questionable if it can be performed
in field. Recommends removal. No specific subgroup proposed or assigned for resolution.
 1547 clause 4.2.3 Voltage. The contention is that the parenthetical information on single-phase is
widely misunderstood.
*ACTION – Ride through subgroup to consider and provide their proposed draft text/resolution.
 1547 clause cited 4.2.4 Frequency. It was stated the frequency table 3 default setting of 62 Hz is
above the limit in other standards. It was recommended revising to a value that is consistent with
other standards.
*ACTION – Ride through subgroup to consider and provide their proposed draft text/resolution.
 1547 clause 4.2.4 Frequency. Frequency table 2 has potential conflict on clearing times.
Recommend revising respective clearing times to 300 seconds each.
*ACTION – Ride through subgroup to consider and resolve.
 1547 clause 4.4 Islanding. Participant proposes full review of both the intentional and unintentional
islanding subclauses; proposes consideration as to revising specification of “2” seconds.
o Mark Siira commented that Marcelo Algrain had provided proposed language potentially
useful to describing intentional islanding. Mark gave an overview of Marcelo’s input
(Appendix C) as consideration to address intentional islanding in the P1547 revision.
o Participant commented that black start could be included in a subgroup working on
intentional islanding.
o Participant commented that consideration be given to using portions of IEEE 1547.4 (and
possibly revised) for input to P1547.
 1547 clause 4.1.1 Voltage regulation. Aminul Huque commented that voltage support functionality
extends beyond ride through. For example, the use of VARs under normal conditions for voltage
regulation. A new subgroup was proposed to investigate Voltage topic for requirements and
functionality under normal conditions. Aminul volunteered to lead this subgroup/subtopic.
o An example was stated of how a mandatory requirement for voltage regulation might look
(versus vs. guidance or permissive text). It was suggested the subgroup could draft values
for which, within certain stated conditions, a minimum power factor (+/- VAR range) would
be required.
 1547 clause 4.3.2 Limitation of flicker induced by DR. Participant posed question “Is THD worth
revisiting?” Similarly, it was suggested revisiting the revised IEEE Std 519. Another participant
commented that 519 is a “recommended practice” and not a standard. Participant also
recommended consideration of using by-reference IEEE Std 1453 for flicker. Recommended
formation of a subgroup for this topic.
 EPS specific P1547 requirements and specifications. Meeting participant proposed consideration of
alternate limit ranges for island and weak electric power systems.
An example stated was the possibility for an island system, that P1547 either require or
allow parameter settings that may be outside the P1547 base limits; then, when
implementing P1547, it would not be necessary to obtain approval from the authority
having jurisdiction (AHJ) for exception to base limits in P1547 requirement(s). It was stated
that getting an exception under existing implementation processes hampers some
interconnections on island systems.
There was discussion on the pros and cons of adding multiple “independent” tables
addressing special cases for detailed sites and conditions (e.g., specific EPS characteristics).
Minutes—P1547 Meeting, Las Vegas, June 26-27, 2014


One comment was that implementation practice is up to AHJ requiring the standard.
Another commenter stated the possibility to form a subgroup on island and microgrid
systems (see 1547 clause 4.4).
Screens in P1547 and DER project implementation. A participant proposed establishing P1547
screens similar to the FERC SGIP screens or some of the PUC screens that specify criteria for
characteristics and settings that allow fast-track implementation. Other participant stated the
perspective that 1547 is used as a screen itself—for example, CA Rule 21—and is therefore not
appropriate for establishing screening processes within P1547. Another viewpoint was that fasttrack screens are defined from a (power) system perspective, and are not applicable to equipment
requirements. For example, fast-track screens based on % renewable penetration for circuit; or fasttrack size limits based on power system owner defining threshold below which impacts are known
to be minimal for their specific system.
Technology neutrality in P1547. Participant posed general question – do we break from technology
neutrality? (Chair’s note: this is a recurring topic; see previous minutes – maintain neutrality as
much as practical).
Consensus was that the P1547 would generally maintain technology neutrality. Subgroups
may find and debate where they would propose differentiation based on technology, but
the general approach is to keep as technology neutral as practical. If warranted, technology
differentiation should be as broad as possible, based on fundamental differentiations.
Testing requirements is one example in 1547-2003 where technology differentiation is
stated.
P1547 new or crosscutting topics. The following lists topics that do not explicitly fall under 15472003 clauses. These topics can be pursued by new subgroups and as the ideas within the specific
topics are discussed, draft text should be established for WG consideration.
o Interoperability (e.g., build from IEEE 2030)
o Short Circuit Behavior
o Loss of Load Behavior
o Voltage Support (under both normal state, and “beyond ride through” for abnormal
conditions)
o Power Quality extensions (active filtering, interphase balancing. Could be a permissive
versus a “shall” technical finding).
Next Actions
Chair will circulate subgroup volunteer lists to individuals who signed up. Chair will also request WG
members not present if they wish to volunteer to actively participate in what subgroup(s).
Next meetings were discussed.
 IEEE workshop on full revision of P1547.1 was discussed that tentative plans were being pursued
for the August-September timeframe.
UPDATE: Workshop meeting is being planned for October 1-2, 2014, IEEE headquarters area (save

IEEE Style Example Word Usage
“Shall” indicates mandatory requirements (shall equals “is
required to”).
“Should” is used to indicate a recommendation
(should equals “is recommended that”). Should indicates that
among several possibilities one is recommended as particularly
suitable, without necessarily mentioning or excluding others; or,
should indicates a certain course of action is preferred but not
necessarily required.
“May” is used to indicate a course of action permissible within
the limits of the standard (“may equals is permitted to”).
“Can” is used for statements of possibility and capability,
whether material, physical, or causal (“can equals is able to”).
“must” is deprecated and shall not be used
when stating mandatory requirements; must is used only to describe
unavoidable situations.
(b) use of the word “will” is deprecated and shall not be used when
stating mandatory requirements; will is only used in statements of fact.15
