Vancouver, British Columbia
16 members and guests signed in - Abur, Baran, Butler, Carneiro, Falcao, Fukuyama,
Jones, Julian, Lee, McDermott, Miu, Mori, Pereira, Schulz, Spare, Yazdi
The minutes from Columbus were approved. Carneiro questioned whether we should
"leave device modeling to others". Baran pointed out that current subcommittee members
are not involved in model development and testing, so the direction should reflect member interests.
Pahwa stepped down as vice chair, to assume chairmanship of another SC. The SC approved
McDermott as the new vice chair and Carneiro as the new secretary.
Baran said the backlog of paper reviews has been cleared; only two remain in our hands.
Carneiro said the response time has improved since the last meeting in Columbus. Baran is
not satisfied that the process has been completely fixed. Papers are not always routed to
the most appropriate SC. This is partly the author’s responsibility, but the SC chairs
should also know when a paper should be sent to another PES entity for a better review.
Baran thinks we should be reviewing some of the papers that go to the Distribution Subcommittee.
Baran wanted to acknowledge Kersting’s outstanding service as the Radial Test Feeders TF chair.
Kersting was chairing a panel session this afternoon and could not attend the SC meeting.
Radial Test Feeders
This TF has been disbanded, but we should still explore the possibility of a CAPS article to
promote use of the test feeders in papers and for vendor benchmarking.
Dugan was not present and no report was given. Schulz mentioned one of her students attended
a Multispeak meeting.
TF on Feeder-level Modeling of DG
The WG approved a new task force with the following scope:
Investigate methods and prepare a paper describing the impact of DG on feeder-level
methods for the analysis of power flow, fault, reliability, and overcurrent protection
system response. Assess the use of transmission system stability methods and models on
distribution systems with DG. Define the data requirements for DG models in feeder analysis.
Identify conditions where more detailed (eg., time-domain simulation) methods must be used
for analyzing feeders with DG. The task force will consider distributed storage devices along
with distributed generation.
McDermott is the TF chair. We need to coordinate with a WG under the Distribution
Subcommittee of T&D, focusing on system impacts of DG. We also need to coordinate with
a WG under the General Systems Subcommittee of T&D, focusing on device models especially
Intelligent System Applications Subcommittee Update
As liaison, Butler reported that a TF of this SC will sponsor a panel session
at the 2002 WPM on “Fundamental Concepts of Intelligent System Applications to
Distribution Services”. They are also preparing a review paper on the same topic.
Butler is the panel session chair.
The subcommittee will sponsor a panel session at the 2002 Winter Power Meeting
in New York, on the topic "Fault Detection, Analysis, and Restoration (FDR)",
to be coordinated by Schulz. Presenters include Schulz (use of outage management system),
Miu (short-circuit modeling), Jones (Web link between SCADA and analysis), and Butler
(shipboard restoration). This should be scheduled for Wednesday morning, or Monday afternoon.
There will be a panel of 6 vendor presenters at the T&D show, covering software
tools for distribution reliability and restoration analysis.
Baran reiterated the tutorial on distribution analysis guidelines as a long-term goal.
He asked WG members to send him contributions or suggestions, as a prod to have an outline
ready to discuss at the 2002 WPM. Jones offered to send material.
PSACE Committee Update
The proposed merger with PSPO is on hold, and the two committees did not meet jointly
Distribution Subcommittee Update
The WG on DR Integration had 37 attending Tuesday's meeting. They plan to develop a
"laundry list" of interconnection issues at WPM 2002, and present a review paper on this
at a SPM 2002 panel session, with followup presenters on specific issues. They will address
DR "out on the feeder", including both radial and network systems. There is no TF breakdown
at this time. Chair is Reigh Walling, Vice Chair is Charles Perry of EPRI-PEAC.
John Redmon said the Lifelong Learning committee plans to record and sell all future
tutorials. Presenters may have to sign away these rights in exchange for an honorarium,
perhaps $500 split N ways. This might be a consideration in planning future tutorials.
Dan Sabin (DSC review coordinator) was advised outside the meeting that he could re-route
analytical papers to DSASC for review. Of course, the whole procedure may be changing anyway.
General Systems Subcommittee Update
The WG on DR Modeling and Analysis has two TFs, one for DR interfaced via power electronics
and the other for "conventional" (synchronous machine) DR. The respective TF chairs are Reza
Irivani and Tom Key. Each TF is still developing a scope. Apparently these will be broken down
by modeling regime - steady state, small signal, large signal, and electromagnetic transients.
