Electric vehicles charging under a G2V and V2G approach:The case of the Portuguese power system
There is a growing awareness that the widespread adoption of electric vehicles(EVs),as an alternative to vehicles with internal combustion engines,will add new load to the electricity power systems and will therefore have a significant impact on electricity generation and the stability of the grid.On the other hand,the transition to electric propulsion powered by batteries has the potential to establish a synergistic connection between EVs using vehicle-to-grid(V2G)technology and the electricity grid.Given that vehicles are typically used for transportation purposes for less than 5%of their life time,all-electric vehicles could serve not only as electricity consumers when charging their batteries under a grid-to-vehicle(G2V)approach,but could also play the role of a distributed storage system that enhances the operation of the grid under a V2G approach.In this context,this paper presents a detailed study for the case of the power supply system in Portugal over the period 2010-2030 in order to assess and analyse the potential impact of EV technology adoption on the national grid,taking into account the existing plans for expanding its capacity.To this end,the present work employs the Integrated MARKAL-EFOM System(TIMES)to examine a number of scenarios under varying levels of EVs penetration into the fleet mixture and different charging profiles,namely unregulated charging of G2V passenger cars and night charging of V2G passenger cars.The results obtained highlight the importance of regulating the charging process of EVs and show that the integration of EVs with V2G capabilities into the grid has the potential to deliver significant benefits to the national electricity system in Portugal.
