Assessment of EV charging strategies and their effect on residential grids using co-simulation

This paper presents results from a co-simulation based study to assess the interaction of electric vehicles (EVs) with the residential electricity distribution grid. The impact of this interaction on the grid as well as on the EV charging objectives is studied. The impact of EV charging strategies on the grid is measured in terms of deterioration of the quality of the grid voltage and overloading of the grid assets. The performance of the charging strategies from EV owner’s perspective is studied using metrics such as delay in charging and average cost of charging. The charging behavior of the EVs has been incorporated using models based on empirical data collected from public chargers in the Netherlands. A modern residential grid with high adoption of renewable resources is simulated using the co-simulation platform Mosaik which enables synchronized simulation of all the grid components along with a possibility to integrate external control signals.
