A spectral clustering method of taking the space topology relationship and the voltage data dependency of the power network into consideration
The voltage is one of the important criteria for the evaluation of the electric energy quality,as well as the sign of reflecting the reactive power balance and reasonable distribution electric power system.Distributed voltage control is a kind of fast and effective controlling method.To deal with the complicated conditions of the divided boundary,this article leads into the concept of the temporal and spatial boundary constraint set,putting forward the method of spectral clustering partition of the boundary constraint set.Firstly,the way of obtaining the distributed numbers is given specific to the electric power net.Then,the voltage time series analysis is carried on the base of the space relationship.Betweenness,degree and other complex internet and intranet concept have been brought in to evaluate the importance of node,the definition of the partition degree has been made through the data visualization.Dividing the boundary node into whirlpool node and isolated node,dealing with them separately.When the voltage fluctuation takes place,the reason can be made clear,the prediction about chain fluctuation spreading tendency will be made and the regulation and control scheme will be given.Application in some provinces electric power net system has saved the computing time and improved the response speed.
