Abstract: Automatic demand response（ADR） is the latest implementation in Energy Internet, and how to achieve it for electric vehicle（EV） charging and discharging helps to improve the response. In this work, an ADR method for EV charging and discharging was proposed to achieve supply-demand coordinated optimization（SDCO-ADR）. Taking the customer charging demands and distribution system load profile into account, the proposed method seeks to achieve the maximum consumers’ profit and lower load fluctuation by conducting the ADR project with the incentive-based and price-sensitive demand response. On this basis, the automatic decision model for consumers’ response willingness was built considering their mentality and the risk which takes the conditional value at risk as the measurement index, to realize automatic demand response for EV charging and discharging in distribution system. With a local distribution network as the test system, simulation results indicate that supply-demand coordinated optimization is achieved under the proposed method, the average annual earnings per vehicle can be improved greatly, and load variance and peak load can be reduced effectively.
