摘要
可再生能源配额制与现货市场建设的并行推进引起风电发电商、光伏发电商及储能电站(风光储)联合参与现货市场的交易决策发生变化。通过构建双层交易决策模型,对可再生能源配额制下风光储联合参与日前电能量及调频辅助服务市场的交易决策进行求解分析。模型上层以风光储总利润最大化为目标,同时考虑到风光储的内部调控,求解风光储最优交易策略;下层实现日前电能量和调频辅助服务市场的联合出清及绿色证书市场的清算。通过库恩-塔克(Karush-Kuhn-Tucker,KKT)条件、强对偶定理等方法将双层模型转换为混合整数线性规划问题进行求解。最后,通过算例验证了所提模型的有效性。结果表明:所提框架与模型能够优化风光储报量报价决策;可再生能源配额制的引入丰富了风光储的套利手段,风光储内部调控更加活跃;风光渗透率及配额制考核权重的变化对风光储的交易决策有重要影响。
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.
