Analysing effective lighting devices impact on power quality and electric grid efficiency by means of FBD-power theory

Currently the impact of high efficient lighting devices such as compact fluorescent lamps (CFL) and light emitting diodes (LED) is an important concern for the electrotechnical community. This paper makes a contribution towards determining the impact of these devices on electric grid power quality and efficiency, proposed by means of applying FBD-power theory to the currents absorbed by CFLs and LEDs. An analysis of the waveform distortion regarding the standard IEEE 519 and efficiency detriment quantification are presented.
