摘要
"碳达峰、碳中和"目标和新型电力系统构建促进新能源不断发展,对于储能设施提出更高需求.在此背景下,在对风电场进行储能配置时,考虑定价机制下利用共享经济模式对储能进行配置优化,并探讨计及风电出力不确定性对储能配置方案的影响.首先,基于主从博弈制定价格,提出一种以共享储能运营商为领导者,以各风电场为跟随者,并最大化各主体利润的共享储能优化配置模型;然后,针对风电出力波动,引入基于矩信息的分布鲁棒优化方法构建机会约束以描述不确定性,采用矩信息完善模糊集以降低模型保守性,通过切比雪夫不等式将各风电场模型重构为混合整数二阶锥规划模型以便求解;最后,通过中国西北地区某实际风电场数据进行算例分析,结果表明,所提优化配置模型能够减少冗余投资,促进储能参与配置并应对实际风电波动.
Abstract
The goals of carbon peaking and carbon neutrality and the construction of new power system have promoted the continuous development of new energy resources,while bringing along higher demands for energy storage.When configuring energy storage for wind farms in the power system,the shared economic model is used to optimize the configuration of energy storage with consideration of the pricing mechanism,and the impact of wind generation uncertainty on the energy storage configuration scheme is discussed.Firstly,based on the Stackelberg game for determining the price,a shared energy storage optimal configuration model is proposed,in which the shared energy storage operator is the leader,wind farms are the followers,and the profit of each participant is maximized.Then,to address the fluctuations of wind power output,a moment information-based distributionally robust optimization method is introduced to construct chance constraints to describe uncertainties,where the moment information is used to complete the ambiguity set to reduce the conservatism.The wind farm model is reconstructed into a mixed integer second-order cone programming model through Chebyshev inequality for solution.Finally,case studies are conducted based on the actual wind farm data in Ningxia,and the results show that the proposed optimal configuration model can reduce redundant investment,promote energy storage to participate in configuration and address the actual wind power generation fluctuations.
