“Power quality describes all aspects, which relate to the voltage and current waveforms present in the electrical power system such as frequency, phase and amplitude.
Distributed renewable electricity generation and novel electronic equipment have in common that they are often interfaced by means of converters, which are electrical devices based on power electronic components with nonlinear current and voltage characteristics. On the one hand, converters themselves contribute to a poor power quality, whereas on the other hand they are very sensitive to it.
In my research, I am dealing with the described so-called “paradox of power quality”, in which I analyse how and to what extend e.g. flexible industry load equipment can contribute to an enhanced power quality. In other words, I want to use converters already connected to the electrical power system in order to improve poor power quality within the grid.”
