摘要
针对规模化灵活性资源的管理需求,提出了一种内近似约束空间整合的灵活性资源集群响应方法。首先,建立储能、温控负荷和电动汽车充电桩的通用模型,并通过紧凑型约束空间描述其响应特性。其次,采用一种基于内近似与闵可夫斯基和的约束空间整合方法,实现对多个灵活性资源响应特性的整体描述。然后,采用一种灵活性资源集群的双层响应方法,既可利用整合后的等效模型形成集群的整体响应策略,又可根据个体特性和整体特性的映射关系,直接得到群内各个灵活性资源的响应策略。最后,通过仿真验证了所提方法的有效性。
To meet the management requirements of the massive flexible resources,a flexible resource cluster response method based on the inner approximate and constraint space integration is proposed in this paper.First,the response characteristics of the energy storage,the thermostatically controlled load,and the electric vehicle charging piles are described based on the general energy storage model,and then formulated by a compact constraint space.Second,an inner approximate and Minkowski sum-based constraint space integration method is used to describe the overall response characteristics of the multiple flexible resources.Furthermore,a two-layer response strategy of the flexible resources is proposed,which not only provides an overall response strategy for each cluster,but also realizes the detailed response strategy for each flexible resource according to the mapping relationship between the individual and cluster characteristics.Finally,simulation results are employed to demonstrate the effeteness of the proposed method.
