Chairman Baran welcomed all the attendees which was followed by
introductions.
A membership list was circulated to record attendance and to make
changes. Also, it was announced that DSA subcommittee has a web page
which can be accessed from the IEEE PES web page.
Minutes of the Winter 98 meeting were approved.
FUTURE ACTIVITIES:
Baran asked members to provide suggestions regarding panel sessions
and other activities, such as tutorials. Available software products
was suggested as a topic for panel session. This will include
presentations by software vendors based on analysis of test feeders.
The analysis could include power flow, fault calculations, reliability,
transients, and harmonics. Probabilistic methods and distribution
system analysis methods were also suggested as topics for a panel
session. McDermott agreed to organize a panel session on distribution
system analysis methods.
TEST FEEDERS:
Kersting made a short presentation on his previous paper on test
feeders. He mentioned that the main purpose of the test feeders has
been for load flow and fault calculations. He outlined some of the
shortcomings of the existing test feeders as well as proposed changes.
Proposed changes include rounding-off loads to integer values, expansion
of system to include additional switches and ties to adjacent feeders,
modification of transformer models, and modification of regulator model.
Other items for possible inclusion are dispersed generation, secondary
systems, and load allocation. He asked members for suggestions.
Christie mentioned that standard distribution reliability systems
have information on protection systems. Therefore, it will be useful to
include data on protection devices to allow reliability
calculations.
Zhu said that results should be included for bench marking. Further,
he wanted inclusion of GIS data to create the original system. He also
expressed an interest in inclusion of protective device data.
Baran suggested that models should be provided with the results
because component models are not standardized.
Hermann mentioned that loads are not static but have stochastic
characteristics. He also said that assumptions for removal of neutral
wire should be defined.
Zhu mentioned that in some applications multiple feeders are needed
instead of single feeders.
This was followed by some more discussions. It was felt that load
modeling is a complex issue and is a separate topic by itself. This
could be addressed in a future panel. Also, it was suggested that
issues for modeling components could be addressed in a panel.
Kersting said that he will work on the test feeders and provide
information to the members.
PRESENTATION:
Stephen S. Miller made a presentation on Data Dictionary
