Abstract: As a mobile energy storage facility, electric vehicles can enhance the stability of power system through vehicle network coordination. With the rapid development of electric vehicles, how to design the business model of electric vehicle charging and discharging has become an urgent problem that needs to be solved. In view of this, this paper designed two business models for EV aggregators, including their sole participation in spot market and joint participation in spot market and auxiliary service market. At the same time, considering the influence of electricity price uncertainty and battery capacity decay, economic calculation and multi-factor sensitivity analysis were carried out for the above-mentioned two models. Case study shows that the EV aggregators′ joint participation in spot market and auxiliary service market is economically better than their sole participation in spot market. Finally, based on the research results, the paper designed a business scheme for electric vehicle aggregators participating in the electricity market.

Key words: electric vehicle aggregator, spot market, ancillary service market, electricity price uncertainty, capacity decay
