The power electronics interfaces of distributed generation units in microgrids usually employ droop control for defining their active and reactive power injections. The voltage and current control loops can be implemented in different ways, presentin

2014 16th International Conference on Harmonics and Quality of Power (ICHQP).
Traditional analysis of waveform distortion assumes balanced and steady-state conditions. However, due to the widespread use of power electronics, non-linear loads and a multiplicity of harmonic-producing loads, power signals are becoming increasingl

2014 16th International Conference on Harmonics and Quality of Power (ICHQP).
Traditional harmonic distortion analysis assumes balanced and steady-state conditions. Moreover, harmonic components are often associated with certain sequences (positive, negative or zero). However, in reality unbalance causes the existence of all s

This paper presents laboratory results on the behavior of time-varying harmonics caused by an electronic converter under a voltage sag and load variations in order to demonstrate the validity of digital time-frequency decomposition methods. A filter

The modular multilevel converter (MMC) is based on the cascaded interconnection of half-bridge switching sub-modules. It features modular characteristics that allow its expandability while providing high quality voltage and current output waveforms a
