Fundamental changes can be presently observed in the distribution networks. The number of equipment with power electronic interfaces is growing continuously, while the amount of linear loads decreases. Photovoltaic inverters, electric vehicle chargers and LED lamps are just a few examples. As a consequence of this development, some changes in the importance of individual Power Quality phenomena can be observed. In particular the frequency range 2 – 150 kHz (supraharmonics) got an increasing attention during the last years. Furthermore modern power electronic equipment usually exhibit power-dependent changes in waveform distortion, which is typically correlated with changes in equipment performance (e.g. efficiency). The number of equipment capable to measure Power Quality (e.g. smart meters with Power Quality functionality) and consequently the amount of available measurement data grows vastly. This requires novel approaches for automatic analysis and efficient presentation of Power Quality data. An increasing observability also enables a continuous assessment of the contribution of a customer installation to the Power Quality in the network. Compared to relying only on emission limits calculated in the planning stage this can improve the utilization of networks with respect to Power Quality and avoid unnecessary conservative limitations of customer emission. The panel discusses recent finding and ongoing research activities on the above mentioned aspects and provides a comprehensive overview of the major Power Quality challenges in future electricity networks.
