“…Data measured before 2016 corresponds to measurements made with a 2.5 kVA amplifier, while lamps measured in 2016 were connected to a 15 kVA amplifier. The amplifiers were compared in [13], showing that both amplifiers are adequate for the characterization of low frequency emission.…”

Measurements have shown that the harmonic currents emitted by lamps with electronic ballast depend on the circuit topology and the existing supply voltage distortion. This paper quantifies the impact of supply voltage distortion on the harmonic and supraharmonic current emission of individual Light Emitting Diode (LED) lamps and compact fluorescent lamps (CFL). It also characterizes several Power Quality (PQ) parameters when those lamps are connected to pure sinusoidal waveform.

“…In spite of being very effective and precise, AFs are seldom used in the practice due to the cost of this technology when compared to passive filters. A second drawback of AFs is that their operation requires a very accurate measurement of load and/or grid harmonic currents, which is not always possible due to limitations in the instrumentation accuracy and availability of meters [9].…”

Due to the high number of photovoltaic (PV) inverters installed, in some regions of the UK the power generated under peak conditions exceeds the transmission system capacity limits. With the aim to mitigate this condition and operate the grid within its design limits, utilities curtail PV output power, thus causing financial loss for the PV system owners and limiting the use of the installed components. The control system proposed in this paper allows using the PV inverter as an Active Filter (AF), when the output power is curtailed, thus improving the system power quality and exploiting the installed MVA. A novel contribution is the description of a harmonic derating coefficient which limits harmonic current injection based on the fundamental current generated by the inverter. The proposed application fits within the scope of the smart grid, where multi-functional inverters can be controlled by utilities to improve grid operating conditions.
