The Total Harmonic Distortion (THD) is, among other parameters, one key factor to describe the power quality of a low voltage distribution grid (LVDG) as shown in the EN501601 standard. As part of the Green Access project, a measurement campaign was initialized to obtain data from several transformer substations with focus on voltage stability and voltage quality. In a second step, the gathered data is used to evaluate the impact of the THD on grid-connected power electronics .
