Low carbon technologies integration in smart low voltage network

The impacts of Low Carbon Technologies (LCTs), with emphasis on Electric Vehicles (EVs) and Heat Pumps (HPs), on the low voltage (LV) network were analyzed. The United Kingdom (UK) has a legally mandated policy concerning reduction of greenhouse gasses (GHGs) emissions. Therefore, the integration of LCTs especially EVs and HPs at the LV network is expected to increase in the drive to reducing the GHGs emissions. Future uptake scenarios, adapted from the National Grid studies, of EVs and HPs were developed for the LV network under study. Gridlab-D, an agent based power system simulation software, was employed to model a real urban LV network. The model was run for four different scenarios considering seasonal load profiles and projected EVs and HPs uptakes for each of the year 2020 and 2030 respectively. The results were analyzed in terms of transformer loading, voltage profiles of the feeders, and the ampacity loading of the cables for the different scenarios for the year 2020 and 2030 respectively.
