含有分布式光伏的配电网分区及主导节点的选择

分布式光伏在配电网中的渗透率越来越高,电压集中控制变量维数多、控制过程复杂等问题促进了电压分区控制研究的发展。考虑到电压分区控制中主导节点选择的指标单一,首先基于电气距离的凝聚层次聚类算法对配电网进行聚类分区;然后综合考虑技术性指标和经济性指标,采用基于目标相对占优策略的粒子群算法对主导节点选择的多目标模型进行求解;最后通过改进的IEEE33配电网算例来仿真验证该分区方法的有效性和主导节点选择的合理性。

Distribution Network Partition and Dominant Node selection with Distributed Photovoltaic

With the increasing permeability of distributed photovoltaic in distribution network, the dimension of voltage centralized control variables is many, and the control process is complex,which promotes the development of voltage zoning control. Considering that the index of dominant node selection in voltage partition control is single, this paper first classifies the distribution network based on the condensed hierarchical clustering algorithm of electrical distance, and then considers the technical index and economic index synthetically, and then adopts the particle swarm optimization algorithm based on the relative dominance strategy of the target to solve the multi-objective model of the dominant node selection. Finally, the effectiveness of the partition method and the rationality of the selection of dominant nodes are verified by an improved IEEE33 distribution network example.
