Application of Graph Data Mining Method in Distribution Network Economic Evaluation

In this paper, a hierarchical economic evaluation index system for distribution network is established. The various indicators of the distribution network and the correlation between the distribution network in order to form is proposed. Substructure discovery algorithm is used to. To avoid falling into local optimum, efficient global search capability of particle swarm is applied to substructure algorithm optimization. Finally, an example demonstrates the reasonablity and effectivity of the substructure found algorithm applied into distribution network economic evaluation. Optimization speed with particle swarm algorithm is fast. This study have practical significance to network planning.
