The focus of this work is a long term investigation of PV-infeed, load and voltage data. The paper presents results based on series of measurements in a low voltage grid over nearly three years. The measured values are recorded for each of the three phases every minute. Based on this data, profiles are generated for the PV-infeed and the load of different customer types. The maximum voltage drop of the winter and summer scenario is simulated based on the generated profiles for three years (2014 to 2016). This approach was validated in a former thesis with the data over one year. The objective of the analysis is the investigation of differences in range, frequency and course of time of measured data as well as the simulated values.
