Impacts of Electric Mobility on the Electric Grid

Abstract

Electric mobility is becoming an option for reducing greenhouse gas emissions of road transport and decreasing the external dependence on fossil fuels. However, this new kind of mobility will introduce additional loads to the power system, and it is important to determine its effects on it. As a direct scenario from DATA SIM FP7 EU project, an application related to electric mobility and its impact on the electric grid from Flanders region is presented in this chapter. The chapter begins with a brief description of the electric transmission network for Flanders region and the electric vehicles energy requirements for different mobility zones in this region, obtained from FEATHERS, an activity-based model. In the following section, the main assumptions that allow estimating the total electricity consumption for each mobility area is presented. Once this total consumption per zone has been estimated, an algorithm to link the mobility areas with the nearest substation is developed. Finally, the impact of charging electric vehicles on the transmission substations is examined.
