Distribution Network Operator Pricing Mechanism Considering Electric Vehicle Demand Response Characteristics

With the increasing number of electric vehicles, their charging demand is growing, and the lack of reasonable guidance causes the distribution grid load to overrun its limits, which in turn causes load overheating and other security risks. Based on this background, this paper first clarifies the demand response mechanism of the distribution grid, analyzes the way EVs respond to the time-sharing tariffs and incentive prices of the distribution grid, and establishes a framework for the interaction between the distribution grid and EV aggregators. Second, the cost model of the distribution grid and the revenue model of the EV aggregator are established, and the respective interaction variables are clarified. Finally, the effectiveness of the distribution grid pricing mechanism proposed in this paper, which takes into account the load response characteristics of EVs, is verified through an arithmetic example.
