Proposal of a Compact Outdoor Medium/Low Voltage Substation for Energy Communities

Paper in proceeding, 2021

Energy transition toward smart grids with deep impact of renewables, energy storages and EV charging systems will increasingly promote the establishment of energy communities that own portions of the electricity grid. The energy communities will consist of clusters of multi-unit buildings and or single residential units aggregated sharing a common or multiple medium and low voltage (MV/LV) electrical substations. The size and impact of the location of these MV/LV substations can constitute a barrier especially for highly urbanized contexts where it is very complicated to provide technical spaces inside buildings for large technical systems like transformers, MV switchgears, etc. The idea of this work consists of developing a compact outdoor MV/LV substation to reduce the overall dimensions and to make the execution modularized to facilitate management and maintenance.
