"A Study on the Pricing of Network
Services"
G.
B. Shrestha
Abstract
Transmission costs, both operations costs
and the investment costs, were incorporated as a part of the total system cost
in the electricity rate making in the traditional ways of power system
operation. Although several methods of allocating transmission charges have
been proposed and are in use in practice today, a theoretically rigorous basis
for incorporating transmission charges is yet to be established.
This talk focuses on the study conducted to
compare two marginal cost based transmission pricing methods, which can be
directly incorporated into the energy dispatch models. In both the proposed
methods direct transmission costs (embedded cost) as well as re-dispatch cost
(out-of-merit generation cost) caused by network losses and network congestion,
are accounted under a unified model. One method employs Power Transfer
Distribution Factors (PTDF) to model network related details. The second method
utilizes modified DC power flow techniques to represent the network. The merits
and de-merits of the two approaches are discussed using the results obtained for
a simple 3-node network, and the modified IEEE 24-bus Reliability Test System (RTS).
Speakers’
Biography
Govinda Bol Shrestha was born and raised in Kathmandu Nepal.
He received B.E.(Honors) degree in Electrical Engineering from Jadavpur
University (India) in 1975, MBA from University of Hawaii in 1985, MS in
Electrical Power Engineering from Rensselaer Polytechnic Institute, New York in
1986, and Ph.D. in Electrical Engineering from Virginia Tech, USA in 1990.
His industrial experience spans over wide ranging activities of
electric utility companies. He worked for Nepal Electricity Corporation looking
after the operation and maintenance of distribution systems (1975-76). He was
involved in the design and construction of transmission lines and substations,
rural electrification and micro hydro plants (1976-1979) when he worked for the
Department of Electricity, Nepal. During 1979-1983, he worked through various
stages of Kulekhani hydro-electric project including planning and contract
administration coordinating a number of international financing agencies,
consultants, and contractors.
After graduate studies, he continued in the academic field by
joining Virginia Tech as a Research Associate in 1990. He joined Nanyang
Technological University, Singapore in 1992 where he is an Assoc. Professor at
present. He has taught courses covering wide ranging topics in power systems
and has supervised a number of post-graduate students. His current research
interest include power system operation and planning, power markets, and
Flexible AC Transmission Systems. He has authored a number of publications in
these fields.
Dr. Shrestha has provided consulting services to power related
companies in ASEAN and has conducted numerous short-courses for training power
engineers in the region – Indonesia, Malaysia, Singapore.
Dr. Shrestha
is a Senior member of IEEE and served as the Chairperson of IEEE Power Chapter
Singapore (1999-2001).
