Distributed power supply site selection method based on hierarchical clustering method

Abstract

The invention provides a distributed power supply site selection method based on a hierarchical clustering method, and the method comprises the steps: obtaining an equivalent circuit of a power distribution system, and calculating the network loss incremental rate of each node in the power distribution system and the static voltage stability of each node through the equivalent circuit; normalizing the network loss incremental rate of each node and the static voltage stability of the power distribution system; forming the sensitivity characteristic of each node by using the network loss incremental rate of each node and the normalization result of the static voltage stability; performing clustering operation on all the nodes and the corresponding sensitivity features to obtain a clustering result; and selecting the installation position of the distributed power supply according to a clustering result. According to the method, the clustering analysis thought is introduced in the site selection process of the micro-grid distributed power supply, the limitation that the distributed power supply site selection process based on an intelligent optimization algorithm is prone to falling into local optimum, low in efficiency and the like is avoided, and the uniformly-distributed and effective distributed power supply installation position can be efficiently obtained through the method.
