technical content as at June 2008
SESSION 1
NETWORK COMPONENTS
Scope
Session 1 deals with all aspects related to the components used in the
electricity distribution networks. Many electricity distribution network
assets are expensive and built to provide service over a long life span.
There is increasing focus on the optimisation of the use of these assets
throughout their complete life cycle from design through installation,
operation and maintenance to end of life management. The components include;
cables, overhead lines, primary and secondary substations, transformers,
switchgear plus their control, protection and monitoring systems. Also
included are new active power electronics devices. The session is also
intended to cover standardisation, environmental aspects, ergonomics,
component reliability and the safety of both operating staff and third
parties. The session will also provide an overview of the state of the art
component design and proposals for future components.
Both
the manufacturing and the maintenance of network components is a major issue
for suppliers, electricity distribution companies and major energy users.
This session is an opportunity for these parties and manufacturers to share
their objectives.

SESSION 6
DISTRIBUTION NETWORK AS
ELECTRICITY MARKET PLACE AND IMPACT OF REGULATION
SCOPE
This session deals with
changes in the role of the electricity distribution companies. The
electricity distribution network can provide a common marketplace for
consumers and small-scale power producers. Such a market may call for
intelligent demand response actions based on market price, energy saving,
and efficiency goals. These processes will involve new business models as
well as new technical solutions and include new organisational structures
and administrative routines, new solutions for customer gateway, automatic
meter management systems and commercial IT system tools. The regulation
principles and models are issues of great importance and will influence,
inter alia, the pricing of the distribution service, the quality of supply,
and commercial quality. The changes in the business environment include
enhanced asset management strategies, organisational restructuring, and
consequential improvements in operating efficiency. In addition, there are
many new management issues that arise from the rapid change in focus from
technology to business development. This session provides an opportunity to
compare recent practices and review future directions.
