Consequences of Energy Efficiency Measures Implementation to Buildings' Electrical Systems

Different consequences of energy efficiency measures implementation, in low voltage installations, have been presented and analyzed. Especially, impact of energy inefficient light sources replacement by efficient lamps, and addition of variables speed drives to existing induction machines have been examined. The mentioned impacts have been analyzed on a small low voltage radial distribution network by harmonic power flow calculations. Nonlinear loads were modeled upon laboratory measurements of different compact fluorescent lamps and variable speed drives and harmonic analysis of respective current-voltage waveforms. In addition, impact of variable speed control on refrigeration machines and pumps has been examined and the results presented.
