基于快速搜索与发现密度峰值聚类算法的含有分布式光伏的配电网电压分区协调控制

Voltage Partition Coordinated Control of Distribution Network With Distributed Photovoltaic Based on CFSFDP Algorithm

  • 摘要: 随着大量分布式光伏并入配电网,重要负荷节点电压越限的紧急情况更容易发生,这对当前潮流状态下电压控制的快速性提出了更高的要求。考虑电压集中控制方式控制过程复杂且传统的分区方法耗时较长等问题,首先以节点间的综合电压灵敏度为基础计算节点电气距离,根据电气距离构建节点相似度矩阵,并采用快速搜索与发现密度峰值聚类算法对配电网进行快速分区;然后考虑本地光伏独立调压能力的不足,提出了一种先无功后有功的电压分区协调控制策略;最后通过IEEE33配电网算例的仿真结果验证了该分区方法的快速性和电压分区协调控制策略的有效性。

     

    Abstract: With a large number of distributed photovoltaic power integrated into distribution network, the emergency of important load nodes the voltage exceeds the limit is more likely to occur, which puts forward higher requirements for the rapidity of voltage control by the current power flow calculation. Considering the complicated control process of the centralized voltage control and the traditional time-consuming partition method, the electrical distance of load nodes is calculated firstly according to the comprehensive voltage sensitivity, and the node similarity matrix is constructed based on the electrical distance. The distribution network is partitioned rapidly by using the algorithm of Clustering by fast search and find of density peaks(CFSFDP). Then in view of insufficient voltage regulation capacity of local independent photovoltaic source, the coordinated voltage partition control strategy is proposed considering reactive power and active power successively. Finally, the simulation results of the IEEE 33 nodes distribution network verify the rapidity of the proposed method and effectiveness of the voltage partition coordinated control strategy.
