The integration of new sources of energy like wind power, solar-power, small-scale
generation, or combined heat and power in the power grid is something that impacts a lot of …

With the advent of new electricity production modes, power electronics, LED lamps and
underground cables, new types of disturbances will appear, including an increase in …

This paper discusses two power-quality aspects of LED lamps: harmonics and flicker.
Measurements have been performed of 24 different LED lamps: the harmonic current …

This paper reports the issues and challenges behind the proposal to include interharmonic
limits in the next revision of the IEEE Standard 519 as discussed within the interharmonic …

In recent years, several countries have adopted measures aimed at improving the efficiency
of energy usage and reducing energy costs. One initiative has been to encourage the use of …

A new generalized lamp model capable of simulating a lamp's luminous flux in the time
domain is presented. Reference is made to low power lamps (up to 25 W). The generalized …

The flickermeter described in International Electrotechnical Commission (IEC) Standard
61000-4-15 is widely used to quantify the voltage flicker level in practical applications. The …

This paper presents a tunable flicker meter based on a generalized lamp model that is able
to account for lamp technologies different from incandescent. The generalized lamp model is …

The replacement of incandescent lamps with more energy-efficient lighting technologies has
a direct influence on the way flicker is measured. The International Electrotechnical …

This paper discusses two aspects of the impact of windparks on the waveform distortion in
the power system: emission and resonances. The paper gives a general overview of the …
