摘要
随着我国碳中和目标的不断推进和能源转型的加速,电力市场的重要性日益增加,这对虚拟电厂(virtual power plant,VPP)参与电力市场提出了新的挑战与机遇。针对VPP如何优化能量-调频市场竞价策略以实现利益最大化的问题,提出了一种VPP参与能量-调频市场的最优竞价策略研究方法。首先,介绍并分析了日前电力市场机制;其次,基于Stackelberg博弈原理,构建了VPP参与电能量市场和调频辅助服务市场的双层决策模型,其中上层模型以最大化VPP预期收益为目标,下层模型则以最小化系统出清成本为目标;然后,利用(karush-kuhn-tucker,KKT)条件将双层模型简化为一个混合整数线性规划问题进行求解;最后,通过算例分析验证所提出交易决策模型的合理性和有效性。算例表明,VPP通过策略性报价能在市场中获得更多的收益。
With the continuous advancement of China's carbon neutrality goal and the acceleration of energy transformation,the importance of electric power market is increasing,which puts forward new challenges and opportunities for virtual power plant(VPP)to participate in the electric power market.Aiming at the problem of how to optimize the bidding strategy of VPP in energy-frequency regulation(FM)market to maximize the benefits,this paper presents a research method of the optimal bidding strategy of VPP in energy-FM market.Firstly,the paper introduces and analyzes the current electricity market mechanism.Secondly,based on Stackelberg game theory,a bi-level decision model of VPP participating in the power market and FM auxiliary service market is constructed.The upper layer model aims to maximize the expected revenue of VPP,while the lower layer model aims to minimize the system clearing cost.Then,the two-layer model is simplified to a mixed integer linear programming problem by using KKT conditions.Finally,the rationality and validity of the proposed transaction decision model are verified by an example analysis.The example shows that VPP can get more profits in the market through strategic quotation.
