Measurement-based determination of static load models in a low voltage grid

Abstract

The paper presents the results of determining parameters of an exponential load model at the low voltage side of a transformers. The input data was generated by continuous measurements in the resolution of one second over the period of one year. The identified parameters are clustered by different times of the day and weekdays. The found parameters are finally compared to parameters in the literature. Further research steps are discussed by presenting a combined approach for determining a ZIP model based on an exponential model. A future goal will be the usage of measurements currently available by smart metering applications which is discussed in the paper.
