摘　　要：随着配电网中分布式电源的渗透率不断提升,传统配电网正逐步向主动配电网转变。主要考虑工业聚集区需求响应特性,研究含高渗透率分布式电源的工业聚集区配电网扩展规划问题。首先,分析工业聚集区的能量供需特性;其次,计及工业聚集区功能块的需求响应特性,构建含高渗透率DG的配电网扩展双层规划模型(其中:上层规划层用于确定DG的配置容量、地址以及网络的扩建和增容;下层运行层考虑了风电、光伏发电多种复杂运行场景的组合,并考虑了工业聚集区参与需求响应的运行约束);最后,采用某地20 kV实际配电网(工业聚集区)62节点系统,验证了该方法的有效性。With the increasing permeability of distributed generators(DG)in the distribution network,the traditional distribution network is gradually transforming into the active distribution network.This paper studies the expansion planning of distribution networks in industrial agglomerations with high penetration of distributed power sources,mainly considering the demand response characteristics of industrial aggregation districts.Firstly,the energy supply and demand characteristics of industrial districts are analyzed.Then,considering the demand response characteristics of functional blocks in industrial districts,a two-layer planning model of distribution networks with high permeability DGs is formulated.The upper planning layer is used to determine the capacity and the address of DGs as well as the capacity expansion and new construction of the distributed network.The lower operating layer considers the combination of wind power and photovoltaic power generation in a variety of complex operation scenarios,and models the operation constraints of industrial districts participating in the demand response.Finally,a 62-node system of a 20 kV actual distribution network(industrial districts)is used to verify the effectiveness of the proposed method.
