The parallel promotion of renewable portfolio standards(RPSs)and spot market construction leads to changes in the transaction decisions of wind power producers,photovoltaic producers,and energy storage power stations jointly participating in the spot market.This paper constructs a bi-level transaction decision-making model to solve and analyze the transaction decisions of wind/photovoltaic/energy storage jointly participating in the day-ahead energy and frequency modulation auxiliary service markets under RPSs.The upper level of the model solves the optimal transaction strategy of wind/photovoltaic/energy storage with the goal of maximizing the overall profit by considering the modulation within wind/photovoltaic/energy storage.The lower level realizes the joint clearing of the day-ahead energy and frequency modulation auxiliary service markets and the clearing of the green certificate market.Then,by using Karush-Kuhn-Tucker(KKT)conditions,the strong duality theorem,and other methods,the bi-level model is recast into a mixed-integer linear programming problem to be solved.Finally,an example is given to verify the effectiveness of the proposed model.The results show that the proposed framework and model in this paper can optimize the bidding strategies of wind/photovoltaic/energy storage.The introduction of the RPSs enriches the arbitrage means of wind/photovoltaic/energy storage,and the modulation within wind/photovoltaic/energy storage is more active.The changes of wind/photovoltaic penetration level and ratio of RPSs have an important influence on the transaction decisions of wind/photovoltaic/energy storage.
