A Review on Implementation of Vehicle to Everything (V2X): Benefits, Barriers and Measures

Increasing the number of electric vehicles (EVs) is necessary to support decarbonization of energy systems. Although high penetration of EVs brings new challenges to power systems as to provide sufficient energy and capacity for EVs charging, discharging of EVs would be a supportive option for electricity grid operators. Vehicle to everything (V2X) is the capability of EVs to support the grids through the vehicle to grid (V2G), vehicle to home (V2H), vehicle to load (V2L), vehicle to building (V2B) and vehicle to vehicle (V2V) technologies. The V2X technologies accelerate the electrification of the transport sector by creating added values for EVs. This paper provides a review of V2X implementation and the classification of the main benefits, barriers of V2X and possible measures to overcome. An overview of recent V2X demonstration projects worldwide has been presented along with their aims and scopes. Three groups of main benefits (i.e., social acceptance, market benefits, and economic benefits) are identified and discussed. Main barriers for V2X are categorized into four groups (i.e., technical, economic, regulatory, and social) and discussed. The paper also discussed possible measures to overcome the barriers to support successful implementation of V2X.
