INTRODUCTION

Energy is being transmitted over greater distances. The further energy is transferred, the harder it is
to maintain constant voltage on the transmission system and the higher the losses. Delivering
energy over greater distances requires greater reactive support and could lead to voltage instability.
It is necessary to look into ways of assessing the extent of the energy losses and discuss developing
technologies that can reduce the loss and improve energy efficiency.


The objectives of this panel are to share experience and knowledge in:

Developing technologies to reduce energy losses in power generation, transmission and
distribution and electric power conversion systems
Reducing energy consumption in the residential and commercial sectors
Employing information technology systems to increase the efficiency of energy used in
processes and buildings; and
New techniques and algorithms for loss assessment and control.

Through case studies, worked examples and open discussions, delegates will have the
opportunity examine energy loss reduction in all areas of energy use (utility, industrial,
commercial, and residential).
Areas of opportunity include:

Automatic generation control
Load management
Flexibility AC Transmission Systems in reducing Energy Loss
