IEEE SCC21 P1547 Working Group Meeting Minutes, June 1-3, 2015, Waltham, MA
“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/Treasurer: Charlie Vartanian
The fifth meeting of the P1547 Working Group (WG) was held in Waltham, MA, on June 1-3, 2015, at
National Grid’s Reservoir Woods facility. The targeted outcomes for the meeting were to review the
latest proposed edits for creation of P1547/Draft 2, and receive direction from WG for each subgroup
going forward.
Summary highlights. Each subgroup presented its latest proposed draft edits and other progress since
the last WG meeting. The attendees responded to straw man (show of hand) votes on specific technical
alternatives for text for draft 2, and to provide other direction to the subgroups for next iteration of
draft updates and work going forward. The input and guidance received by the subgroups will be
incorporated into updated edits for creation of draft 2, which will be finalized following this meeting and
then posted to CDT. Subgroups will continue to hold their webinars and telecons, and the P1547
Officers will continue to have telecons to track overall progress. The WG decided on October 27-29,
2015 for the next WG meeting in Tempe AZ; facilities sponsored by Salt River Project (SRP).
Monday, June 1, 2015, day 1
Meeting called to order and intro
The meeting was called to order at 8:30am. Attendees (Attachment A) were welcomed by Tom Basso,
Chair of IEEE P1547. Tom thanked National Grid for sponsoring the meeting facilities. Babak Enyati of
National Grid welcomed the attendees and provided meeting room and building logistics information.
Tom presented the agenda for the meeting (Attachment B slides), received WG approval of the prior
meeting minutes, reviewed planned activity for the next several days, and had the P1547 Officers
introduce themselves.
Tom presented the introductory slides and made a call for potentially essential patents. No potentially
essential patent claims were declared, and no holders of potentially essential patents were identified.
Attendees then introduced themselves and their affiliations.
Charlie reviewed the current P1547/Draft1 document highlighting the subclauses that have been edited
for creation of Draft 1. Results were reported for the online poll on clause 1.3 Limitations, which was an
action item from the February 2015 WG meeting. The poll results call for P1547 clause 1.3:
1) elimination of any specified DER capacity limit, and
2) to not state any representative value for P1547 distribution primary voltage level.
Preview of DRAFT 2 edits and issues for further development
The remainder of Day 1 was spent with each subgroup providing their work status, a preview of the
latest Draft edits, and any issues they will cover in detail tomorrow.

Folder 4, Interoperability, Mark Siira
Mark gave his status update using a presentation. Despite some significant individual efforts by several
team members to develop a draft, a consensus draft was not achieved prior to the meeting, proposed
draft edits for 4.1.6 were not agreed upon at subgroup level. Therefore, no proposed edits were
presented.
Mark presented his slides, and then asked the meeting participants to identify the top three requirements
for the monitoring and control of DER. The floor was opened for comment, and each person was offered
the chance to provide feedback. Recap of key input follows.



DER should report: 1) On or Off Status 2) Energy output, 3) Ability and availability to change
status; additionally:
o recommendation to add expansion to reporting of status. If off, provide the reason. It
could limit ability to come back online, e.g. off due to high line voltage, thermal or other
limit exceeded within DER unit, etc
o agreed with the three above, but also add reporting of monitored line voltage
o output reporting should include both real and reactive power
o numerous other attendees voiced support for these three basic metrics.
Consider communication system operability during abnormal condition. For example, if grid is
offline, can DER communications still work? Is there a minimum requirement to operate during
abnormal conditions?
Whatever requirements are selected, the “deminimus” 3-4 metrics should be identified as
required
In addition to the deminimus, the “nice to have” metrics should be included. In particular in
context of the data/info exchange required to implement specific use cases
Another variation to the three DER report items: in addition to reporting ability to come on line
(return from off to on), report the kW available to come online
Report power factor (note, similar to reporting real and reactive)
The DER should have ability to load operating profiles
Inverters should report operating mode. Current injection or voltage source.
Standard information models should be required. Leave latitude on what is reported, but require
that the information is provided in a common standard format.
Standard communications protocols should be required
NERC CIP must be considered (some group discussion of generalizing vs citing NERC)
MIC must allow for aggregation.
Need an abstraction layer on line side of PCC. Could be multiple entities interfacing with DER.
(analog of aggregation on the DER side).
DER should receive permissive signal that it is OK to connect to EPS. DER should provide a
feedback signal indicating if it is online. DER should also provide operating metrics in its feedback
signal.
Reiterated need for standard info models and comms protocols
Guidelines on frequency of the communication exchange by the DER. Should the frequency
correlate to capacity: infrequent for small systems, all the way to near real time for very large
systems?
Provide some guidance on minimum required physical comms infrastructure
Comment was made that 1547.1a Clause 5 provides guidance on minimum comm requirements
in context of testing.
Mark outlined the folder 4 approach to keeping the requirements and the most important supporting
content in the body of 1547, and placing informative and useful info in an informative Annex to 1547.

Folder 5, Special Interconnections, Charlie Vartanian
Distribution secondary networks
Charlie displayed the proposed edits that Mike Coddington and his Networks subgroup have
developed for Draft 2. Charlie highlighted that the latest edits combine those requirements
common to both Secondary and Spot networks, and that the subclause specific to those network
scenarios are intended to just include requirements specific to both spot or secondary networks.
The edits were identified as being posted on CDT, and WG was invited to review them and
provide Mike feedback.

Intentional islands
Leo gave a presentation on this topic. The presentation included his subgroup’s latest redline
edits for 1547 Draft 2. Leo posed the following questions and facilitated group discussion in
response,
Should unintentional island subclause be expanded. Should other means of implementing
Intentional Islanding be considered in the revision. WG consensus was yes, for considering this
within Leo’s activity/team.
Should the standard use the term microgrid versus intentional island? No clear consensus on
terminology, but consensus that this is a question his team should address. One caution on
extending scope of 1547 to “community” microgrids, that generally include a portion of the EPS in
the defined island.
Additional discussion posed the idea that modeling and simulation may be an option to
supplement physical testing of an island for interconnection impacts and compliance
Jens B. recommended that the next WG meeting include an agenda item on the topic of Modeling
& Simulation.
Chair prompted discussion of other special interconnection topics that have been identified, but are
not currently being addressed. These include energy storage and grid-interactive EV’s.
Taylor Hollis volunteered to facilitate a study group on the topic ES. The plan is to start this work
within the Special Interconnection Folder. The initial questions include – is ES adequately covered in
1547, if not what pursuits are recommended.
Folder 2, General Requirements, Voltage Regulation, Babak Enayati
Babak displayed the “clean” version of his subgroup’s proposed edits for Voltage Regulation. The
clean and redline edits for Voltage Regulation are posted on CDT. Babak and Aminul then
provided a preview of the material for the detailed working session planned for tomorrow during
the Day 2 meeting.
Folder 3, General requirements, Response to abnormal conditions, John Berdner
Jens Boemer and John provided an overview of the work by the Folder 3 subgroup. A summary
presentation from slides was given by Jens, to provide broad overall status using ‘green yellow
red’ light rankings. The slides are posted on CDT, file “01_IEEE P1547_SubGroupIII_Clause4
2_Overview on progress_2015-06-01_FINAL (JSB).pdf”.
One highlighted issue was the need to coordinate the Categories (XYZ and I, II, III) across the
Folder 2 V-Regulation edits and the Folder 3 ride through edits to 1547.
The day 1 meeting was adjourned at 4:45pm.
Tuesday, June 2, 2015, day 2
Meeting called to order and intro
Day 2 to of the meeting was called to order at 8:30am. Babak welcomed the attendees to National Grid.
Minutes—P1547 Meeting, June 1-3, Waltham

Charlie covered admin items. He noted the changes for tomorrow’s Day 3 agenda: addition of 1) review
Folder 4 proposed Draft 2 edits and 2) opening discussion of the Energy Storage topic, to be facilitated
by Taylor. Modified agenda shown in Appendix B below. The WG was also given advance notice that
we’d have a straw poll tomorrow to choose dates for our next working group meeting, this fall at Salt
River Project (SRP), Arizona. The admin items ended with an invitation for new attendees to introduce
themselves, and request for everyone to initial the sign in sheet, each day.
The remainder of the Day 2 was used for detailed discussion of proposed edits and open issues for
Folder 2’s Voltage Regulation, and Folder 3’s Ride Through topics.
Folder subgroup discussion of proposed draft 2 edits
Folder 3, General requirements, Ride through, John Berdner
John, Jens and Reigh co-presented an overview of their draft edits and framed several open issues in
need of WG feedback.
They worked from both their summary presentation slides and their proposed Draft 2 edits, prepared
for this meeting, and made edits directly during this interactive session. The initial file showing the
latest proposed edits for Voltage and Frequency Ride Through is posted on CDT, file “D IEEE P1547D1_Input from F3 GR2-Clause 4 2_EndConfCall-May14.docx”.
The floor was opened for questions and comments from the WG meeting attendees. The following
recaps key points the co-presenters noted on the easel board sheets.
 Question was asked “what is the reference voltage?” Presenters pointed out that 1547 doesn’t
designate the reference (RMS, highest phase, etc. and, at this point neither does the revision.
This remains an open issue for consideration if a reference is needed and what it should be.
Post-meeting note: see 1547 clause 4.2.3 Voltage -- The protection functions of the
interconnection system shall detect the effective (rms) or fundamental frequency value of each
phase-to-phase voltage, except where the transformer connecting the Local EPS to the Area EPS
is a grounded wye-wye configuration, or single-phase installation, the phase-to-neutral voltage
shall be detected. When any voltage is in a range given in Table 1) …
Meeting feedback on reference voltage options for P1547 full revision included:
o line-line/3-phase
o RMS/fundamental
 positive sequence
o Most severe phase
o Crest voltage
o Average of three phases, with ground phase restriction (circulating current for 3 wire,
neutral return for 4 wire system) possibly incorporated
 Need to clear up default “setting” values being equated with “clearing times”
o Comment for WG – consider one harmonized table for minimum trip and ride through
 Some DER can’t sustain max P at lower frequency. May need to include consideration of power
vs frequency limitations
o Co-presenters highlighted that the subgroup has not yet gotten into operational details.
but, an operation aspect could consider an allowable derate during system frequency
excursion events
 Need to correct typo in default settings for UV2 in category Z
Minutes—P1547 Meeting, June 1-3, Waltham
Page 4
 The word “must” should be changed to “shall” in the several category X, Y, and Z tables. Per
IEEE Standards’ terminology.
Jens led discussion of category X, Y, and Z. Expanded on the presentation slide which gave a
qualified characterization of the three Categories,
X, minimum for base level reliability that all DER should meet
Y, is more stringent and addresses bulk system ‘NERC’ type reliability requirements
Z, is even more stringent, and addresses aggressive distribution scenarios like high PV
penetration
Action item. Folder 3 subgroup’s meeting revised voltage ride through and frequency ride
through draft 2 edits to be sent to the WG secretary within 3 weeks following the meeting.
Folder 2, General Requirements, Voltage Regulation, Babak Enyati
Babak and Aminul co-presented an overview of their draft edits and framed several open issues in need
of WG feedback. Aminul led discussion on proposed Draft 2 edits for Voltage Regulation. The initial file
showing the latest proposed edits for Voltage Regulation is posted on CDT, file “Draft Input for Voltage
Regulation section in the 1547 Full Revision_ver28_ 05222015_Clean Version.docx”.
The floor was opened for questions and comments. The following recaps key points and results of
several ‘show of hand’ polls.
 Show of hands affirmed to remove “lifespan” from opening statement in 4.1.2.1.
o Follow-on discussion led to significant edits to the opening statement; captured as
redlines to the initial draft 2 edits.
 Feedback was requested on need for addressing tolerance in context of voltage regulation
requirement.
o Tolerance was intentionally left out of 1547
o 1547.1 (test procedures) addresses tolerance per manufacturer’s stated specification
o An attendee stated IEC standards do address (mandated values?) tolerance
 A show of hands indicated preference for using the “points” graphical form rather than equation
form for showing the VAR response/characteristic curve for each respective mode (27 votes for
points format, and 10 votes for equation format).
 Inputs were requested on the draft values for the ‘points’, V1, V2, Q1, Q2, etc.. The input was
discussed and any changes to proposed edits were made as “redlines” to the starting proposed
draft 2 edits for V-regulation. The discussion was extensive. Decision was made to use part of
Day 3 to continue the V-Regulation discussion.
The day 2 meeting was adjourned at 4:45pm.
Wednesday, June 3, 2015, day 3
Meeting called to order 8:30 a.m. and intro.
A show of hands poll was taken on 1) WG availability and 2) preference for the dates of the next working
meeting. An attendee confirmed October sponsorship by the Salt River Project (SRP), Tempe AZ. Poll
results affirmed the dates for our next meeting as October 27-29, 2015.

The remainder of the day was used for: an activity status update by folder 6 Testing; continuation of
detailed discussion of proposed edits for folder 3 Voltage regulation and folder 4 Interoperability; and to
discuss next actions.
Folder 6, Testing, Jim Daly
Jim’s status report was that active work to create testing related revisions to 1547 are waiting
on the ride through and voltage regulation requirements being firmed up. He recommended
waiting until there is 95% confidence that content for those requirements are fixed, before
working on the associated testing requirements.
Jim’s outlook is that the several modes of voltage regulation in the folder 2 subgroup’s draft
edits can be supporting by testing. For ride through, that is outside of the scope of the current
1547. However, Jim shared the view and WG added comments that other means of compliance
can be achieved through design validation, simulation, or other testing of subsystems (e.g.,
communications, controllers).
Jim reported that IEEE 1547.1a was published (March 2015). He reviewed the portion of
1547.1a addressing Voltage regulation and shared his observation that the last mode of voltage
regulation listed in 1547.1a-2015 subclause 5.13 is not covered by the draft 1547 edits from
folder 2 Voltage regulation subgroup. The description of this mode in 1547.1a is “Where the
reactive power output of the EUT changes with respect to real power output, the manufacturer
shall specify the response characteristics.” This information was offered for folder 2 subgroup
and wider WG to consider the need for coordinating content on the voltage regulation modes.
Jim’s final update item was that this is his last Working Group meeting that he attend based on
travel considerations. He could participate in live meetings if held in closer proximity to him,
e.g., IEEE headquarters area (Piscataway N.J.). He would continue to participate via webinars.
Folder 2, General requirements, Voltage regulation, Babak Enayati
Babak and Aminul continued their detailed review of their draft edits, took feedback, and
incorporated these into edits during the meeting. The changes were captured as redline edits to
the draft 2 inputs prepared for the meeting.
Action item. Folder 2 subgroup’s meeting revised Voltage regulation Draft 2 edits will be sent to
the WG Secretary within 3 weeks following the meeting.
Folder 2 and folder 3 integration; coordinating revision content between Voltage regulation
and Ride through
Jens led the discussion on behalf of both folder 2 and folder 3 subgroup leads. He outlined the
discussion around the following set of bulleted issues:




Names and meaning of categories, e.g. I, II, II, and X, Y, Z
Voltage measurement
Voltage reference
Terminology of control functions
This discussion concluded with WG consensus that the folder 2 and folder 3 categories should
use consistent labeling and meaning. Per show of hand votes, the labeling will conform to
Roman numeral numbering, i.e. category I, II and III.
Minutes—P1547 Meeting, June 1-3, Waltham
Page 6
ACTION ITEM –Folder 2 and 3 subgroups will provide the WG a recommendation on the common
meanings for Category I, II, and III.
Folder 4, Interoperability, Mark Siira
Mark notified the WG that his team held an ad-hoc breakout, and created a version of proposed
Draft 2 edits for subclause 4.1.6. Mark then displayed and introduced the Folder 4 Draft 2 edits.
These initial edits focused on the body of the standard, e.g. 4.1.6 as the normative text. There is
significant informational content proposed for an informative Annex that will cover background
e.g., on IEEE 2030 interoperability and other relevant standards development organizations
resources that address interoperability and related topics including security.
The discussion was opened up for WG feedback, with Mark, Wayne Stec and Frances Cleveland
facilitating the group discussion. Several changes were made to the initial draft text. These were
captured as redline edits by both Mark and Frances.
Action item. Folder 4 subgroup’s meeting revised interoperability Draft 2 edits will be sent to
the WG Secretary within 3 weeks following the meeting.
New WG study topic, Energy Storage (ES), Taylor Hollis
Taylor opened this discussion by posing a question to the WG as to whether ES needs to be
addressed in 1547. Tom pointed out that energy storage is cited in the definition of DR in 1547.
From 1547-2003, ““distributed resources (DR): Sources of electric power that are not directly connected
to a bulk power transmission system. DR includes both generators and energy storage technologies.”
Taylor refined his point to pose the question whether or not 1547 content adequately covers
potential unique interconnection aspects of energy storage. The WG feedback was mixed, thus
indicating need for facilitated discussion to better frame the concerns of the working group related
to interconnecting energy storage to an EPS.
Taylor volunteered to lead this initial study/framing effort, and asked for expressions of interest in
this contributing to this topic. Taylor passed around a sign-in sheet to gather names and emails
of interested WG members.
Action item – Folder 5 Special interconnections subgroup will provide an initial forum for Taylor
to explore the topic further. By the next WG meeting (October 2015), Taylor will report the
outcome of this evaluation of need to address potential unique interconnection aspects of ES in
this P1547 revision, and if warranted make recommendations on action to revise 1547 for energy
storage.
Next actions and other issues
IEEE 1547.1a (published March 2015): rise time footnote in Annex A.6
Bryan Lydic provided information on the need for potential clarification or correction in the
footnote related to Figure A.6 in IEEE 1547.1a. The figure, related text and footnote from
1547.1a are copied below.
Minutes—P1547 Meeting, June 1-3, Waltham
Page 7
Figure A.6—Graphical representation of power variation test
using step-wise ramp function with n = 4
The 1547.1a related text and footnote related to figure A.6 reads,
“… tr is the rise time of the test signal (tr = t0 – ti)54.
When the step-wise ramp function conflicts with a design characteristic or settings of
the EUT, an alternative method that is agreeable to the manufacturer and the testing
agency may be used.
Footnote 54 reads: “The rise time tr shall be less than the smaller of 1 cycle or 1% of the
settling time of the device for the function under test.”
The issue is that this duration of rise time can result in step-change outputs that exceed device
stability limits. Brian recommends evaluation of a better rise time range, and then update of
1547.1a to reflect the improved range.
Jim Daly pointed out that if this is an error, that the IEEE has a procedure to identify the error,
and publish the revision (e.g., corrigenda needed to correct an error).
Tom requested that 1547.1a should be scrutinized to consider if any errors, or omissions from
the balloted version may exist in the published version.
Action item – Tom invited this WG to send him input on any perceived errors in 1547.1a and
recommended revised text.
Proposed new subgroup on unintentional-islanding and other topics proposed for specific
efforts
Minutes—P1547 Meeting, June 1-3, Waltham
Page 8
John Berdner proposed formation of a subgroup to address unintentional-islanding. An initial
effort of this new team would be to scope the effort of revisions specific unintentional-islanding.
A set of subject matter experts has already been discussing that formation. It has been under
Leo Casey as a lead and he may call for additional WG members interested in addressing the
topic of unintentional-islanding within the 1547 revision.
Action item – Leo to add unintentional-Islanding within his existing subgroup coverage of overall
islanding, within Folder 5 Special interconnections.
Action item – WG members interested in working on unintentional-islanding with Leo should
email their expression of interest to both John Berdner and Leo Casey.
Soft start and reconnection, voltage impacts
Brian proposed that the WG should specify soft start and reconnection as a topic for
consideration. WG discussion concluded with the topic earmarked for evaluation within Folder
7 Power quality (PQ), which is being led by Babak Enayati.
Action item - Babak requested WG members interested in PQ topics email him their expression
of specific PQ interest.
Smart Inverter Functions Information
Frances Cleveland gave a presentation from California’s Smart Inverter Working Group (SIWG)
Phase 3 Activity. This includes a listing of both the basic and advanced inverter functions
identified in CA’s industry stakeholder forum. She recommends that the P1547 voltage
regulation and ride through modes be assessed against the SIWG 7 core (Phase 2) functions and
advanced (Phase 3) functions identified by the SIWG. A PDF copy of the presentation is posted
on CDT, file name “SIWG Phase 3 Advanced DER Functions May 28, 2015 v2.pdf”.
NEXT ACTIONS
Tom recapped the meeting and highlighted some action items:
Action item – Each Vice Chair to send final proposed redline edits (from Draft 1 to Draft 2) to the
WG Secretary, after incorporating the input from this WG meeting. Due date is June 22
Action item– Secretary will consolidate each folder subgroup edits into the new 1547/Draft 2, which
will be the working version for ongoing consideration and the next WG meeting baseline.
Action item – WG Members email any feedback on IEEE 1547.1a to Tom.
Meeting adjourned at 4:40PM, Wednesday June 3, 2015.
