On the project

The project is focused on the development of new algorithm to quantify the flicker severity from voltage measurements in electricity distribution grids. The present flicker severity metric was developed decades ago. It estimates the irritation of human observer by the light flicker of a reference incandescent lamp. The algorithm was optimized with respect to disturbances generated by arc furnaces and adapted to the limited computational capabilities in the past. Recent fundamental changes in terms of lamp types (e.g. light emitting diode based lamps), common disturbance sources (e.g. photovoltaic installations) and instrumentation capabilities raise concerns about the suitability of the present algorithm. This project identifies the most common disturbance patterns in present electricity grids caused by modern power electronic equipment, how human observers are irritated by them considering modern illumination systems and develop new lamp and observation-irritation models. Based on such holistic analysis, a novel algorithm to evaluate flicker disturbances in modern electricity grids is developed.
