Because of severe uncertainty of renewable energy, how to tackle the deviations between the actual outputs and bid outputs becomes one of the most sensitive issues in day-ahead electricity markets. A joint planning and operation strategy of renewable energy producer and electric vehicles aggregator is capable of reducing the deviations. In this paper, a stochastic Cournot equilibrium model of the electricity market is proposed. Based on the oligopolistic competition theory, a virtual power plant including renewable energy producer and electric vehicles aggregator bids in a cooperative mode to participate in the market competition. Moreover, trading priority of renewable energy is considered to ensure the market fairness. This model is solved by the mixed complementarity method. Results show that renewable energy producer bids more profitable as well as alleviating the outputs deviations.
