This session addressed the key issues that need to be resolved in the grid on the way of the massive necessary transition to electric vehicles.
An increase in electric mobility and the accompanying charging infrastructure will have a large impact on the network notably in the medium and low voltage parts. Primarily fast charging infrastructure will be connected directly to medium voltage networks.
When referring to electric vehicles on the road, people normally refer to cars, while a big importance shall be given also to public transportation and to electric trucks.
Running vehicles on electricity instead of fossil fuels shifts energy requirements from petrol stations to power systems. A wide uptake of electric vehicles will increase electricity demand on an electricity network that is already constrained at certain times of the day in certain areas of Europe. The increasing digitalisation of infrastructure already enables smart management of the grid, hence the management of charging points. This makes “smart charging” possible: charging at the most convenient time for the electricity grid and at the lowest cost for the consumer. Moreover, bidirectional-charging infrastructure offers the opportunity to use the electric car fleet as a source of grid flexibility during shortages. The directive on common rules for the internal market in electricity, which builds upon provisions of the Energy Efficiency Directive, aims to provide a coherent framework for demand response that enables smart charging, gives consumers incentives to charge at off-peak times and gives distribution system operators the ability to actively manage the grid.
Despite these opportunities, analyses also reveal that an increasing electric vehicle penetration heavily affects the operation of the energy sector and integration of electric vehicle demand poses very diverse challenges on the management of power system at local, national and European level depending on the respective status of the energy system.
Up to 2030, only local grid congestions due to peak loading of the grid need to be considered. Due to energy efficiency gains, electricity consumption in the EU is likely decreasing faster than the rate of electrification. Therefore, the start-off for electric vehicles market introduction seems to be practically feasible. However, for specific areas with fast charging infrastructure, high concentrations of electric vehicles like city centres or pollution regulated city districts a grid re-enforcement needs to be taken into account.
