Both the sources and solutions to the problems with harmonics and low power factor associated with energy-efficient discharge lamps (e.g. fluorescent or sodium) are described. An assessment of the performance of electronic ballasts, with relation to power factor and harmonics and the impact of...

The aim of this paper is to provide an assessment of the state-of-the-art technologies that can be used for monitoring and evaluating demand-side management (DSM) programs. Additionally, we point out research, development, and demonstration projects where implementation can contribute to a more...

Electricity demand is growing rapidly in Brazil. More efficient use of electricity is cost effective, will reduce the need to construct costly new power plants, have positive environmental impacts, and provide other benefits. It is technically and economically feasible to reduce projected...
