The Role of Electric Vehicle Charging Technologies in the Decarbonisation of the Energy Grid

Vehicle-to-grid (V2G) has been identified as a key technology to help reduce carbon emissions from the transport and energy sectors. However, benefits of this are best achieved when multiple variables considered in process charging discharging an electric vehicle. These include vehicle behaviour, building demand, renewable generation, grid intensity. It is expected that transition mobility will add pressure grid. Using batteries vehicles storage send back during high-demand, carbon-intensive periods impact introducing minimise system. In paper, authors present method propose V2G control scheme integrating one year historical datasets, aiming towards reduction through increased local consumption energy, offset demand low intensity periods, peak battery. The study included assessment strategic location number chargers support fleet five make integrate vehicle-to-grid without impacting current service provision. found proposed helped average per kilowatt (gCO2/kWh) simulation scenarios, despite charging. For instance, tested scenarios reduced 223.8 gCO2/kWh with unmanaged 218.9 using V2G.
