Synthesis of LV load models for MV networks fast transient studies

This paper presents two techniques to obtain LV load models adapted for fast transient studies in MV networks. The first LV load model is based on CIGRE recommendations for harmonic impedance calculus while the second LV load model follows the analysis of the recorded waveforms in time and frequency domains. The results of the proposed models in ATP-EMTP environment are verified against the measured voltage and current waveforms.
