Abstract

As a major DSO in France, Enedis is interested in assessing the Grid impact of high development of Electric Mobility of different ranges and in various areas: rural or urban. For this purpose, this paper establishes a methodology for DSO to predicatively assess the peak electric power required at different locations in a transport network under various charging strategy hypothesis. The analysis uses publicly available data from existing transport networks.A high charging power may impact the grid at the vicinity of depot or opportunity charging stations. This impact may trigger expensive connection costs and potential reinforcement expenses on the distribution network. Statistical tools were created to provide an estimate of the absorbed electric power throughout a normal operation day. Uncertainties around the exploitation of urban transport networks were taken into account.Simulation on three networks across France proved that an overnight charging could have a significantly reduced impact when compared to an opportunity charging on these specific cases of study. Furthermore, a power control strategy enforced at a depot could help further mitigate its impact through a substantial reduction of its peak power. Results also showed that the use of a gathering of opportunity charging stations have a lower impact on the electrical grid thanks to a better control of bus operational stochastic effects.
