【 摘 要 】

In this paper, the benefit model of energy saving and emission reduction for electric vehicles and fuel vehicles are established, the situation of energy consumption and carbon emission between the two sides were comprehensively analyzed. Then, the reliability model of distribution network was established. Based on the theory of peak-valley time-of-use electricity price and V2G market regulation agreement, the reliability of connecting electric vehicles to distribution network is evaluated accordingly. The results show that the energy consumption of electric vehicles is much lower than fuel vehicles and the economy is better. For example, according to 2017 data, more than 130,000 electric vehicles in Beijing can save up 70,000 RMB per kilometer during peak hours. Reasonable connection of electric vehicles to power distribution network can effectively reduce carbon emissions and has remarkable environmental protection effect. Compared with disorderly charging of electric vehicles, V2G market with peak-valley time-of-use electricity price can obviously improve the stability of the system.
