Impact analysis of electric vehicle price mechanism on load demand response of distribution network

In recent years, with the vigorous development of global green energy, the popularization and deepening of electric vehicles are more and more rapid. Because of its “source-load” characteristics, electric vehicles will bring opportunities and challenges to the operation of the power grid. As the intermediary between distribution network and EV, aggregator participates in load demand response by centralized and orderly dispatching EVs. The enthusiasm of EV users to participate in demand response is related to their profit. This paper establishes EV users' profit model, aggregator's profit model and users' satisfaction model. The pricing factors that may lead to changes in EV users' profit and satisfaction are analyzed in detail. The simulation results show that the changes of electricity pricing standard, policy award/penalty and service fee will affect EV users' profit, aggregator's profit and aggregators' demand response ability, so as to help establish a reasonable pricing mechanism.
