| 摘要: |
| 为提高配电网的经济性和电压水平，从网络拓扑结构角度，建立主次级配电网架。基于勒贝格公式的K-means聚类方法对供区进行最优分块，并引入等效负荷点概念；主级网架生成中构建考虑负荷节点和分布式电源出力的时序模型，运用场景削减技术抽取场景并赋予权重，采用雨刷摇摆搜索算法构造花瓣式网架结构；以等效负荷点为电源点构建辐射状次级网架，并以失负荷总量最小为目标为各区加设联络，以降低线路投资，提高系统可靠性。算例分析表明所提构建方法合理且有效，主次网架结构具有较低的建设投资、较高且稳定的电压值和较小的网损。 |

| Abstract: |
| In order to improve the economy and voltage profile of distribution network，the primary and subordinate distribution networks are built from the aspect of network topology. The K-means clustering method based on Lebesgue formula is used for the optimal partition of power-supply area and the concept of equivalent load point is introduced. The time-sequence model considering load nodes and DG（Distributed Generation） outputs is built for the construction of primary network，the scenario reduction technology is applied to extract the scenarios and assign the weights，and the wiper-swinging search algorithm is adopted to construct the petal-like primary network. The radial subordinate network is constructed with the equivalent load points as the power sources，and the tie lines are designed with the minimum total load loss as the objective to decrease the investment and improve the system reliability. Case analysis shows that，the proposed method is rational and effective；the constructed network structure needs less investment，achieves higher and stable voltage and has less network loss. |
