Considering the needs of electric vehicle owners, electric vehicle aggregators, and dispatching agencies, based on the charge-discharge characteristics of electric vehicles, a dual-level management model for electric vehicle aggregators and dispatch agencies based on demand response was established. According to factors such as battery life, controllable state, state of charge, economic effect, etc., four kinds of electric vehicle control order indicators and comprehensive judgment indexes are proposed. On this basis, taking the user travel requirements and other factors into account, an aggregation control strategy for electric vehicles based on index ranking is proposed. The simulation example based on the business district verified the rationality and effectiveness of the aggregation strategy.
