摘　　要：充分调动用户侧负荷资源参与需求侧响应成为解决高比例新能源电力系统供需平衡的有效途径之一。然而,用户侧负荷响应在容量与时域上的不确定因素导致难以有效量化评估其响应能力。为此本文提出一种基于二叉树的台区需求响应建模与聚合调控潜力评估方法。首先,提出配电台区群多时间尺度需求侧响应的三阶段云边协同调控策略;然后,根据用户侧负荷响应的时序特性,提出基于二叉树的需求侧响应响应特性表征方法,建立配电台区需求侧响应聚合模型,采用隶属度参数表征需求侧响应群体响应的不确定性;最后,通过仿真算例验证了方法的有效性。The full mobilization of customer-side load resources to participate in demand response has become one of the effective ways to solve the supply-demand balance of high percentage new energy power systems.However,the uncertainties in the capacity and time domain of the customer-side load response make it difficult to effectively and quantitatively assess its response capability.Therefore,a binary tree based demand response modeling and aggregation regulation potential evaluation method for seismic stations is proposed.First,a three-stage cloud-side cooperative regulation strategy is proposed for the multi-timescale DR of the distribution station group.Then,based on the time-series characteristics of the customer-side load response,a binomial tree based DR response characterization method is proposed;a DR aggregation model is established for the distribution station area,and the uncertainty of the DR group response is characterized by the affiliation parmeter.Finally,the effectiveness of the method is verified by simulation cases.
