Abstract

The invention discloses a high-voltage power distribution network project dynamic selection method based on network analysis. The method comprises the steps: constructing a network model; finishing the calculation of each index on the basis of network analysis, and evaluating the current situation of a power distribution network and project requirements; determining the most preferential project by combining spatial distribution and topological relation of each to-be-selected project; and finally, updating the current situation of the power distribution network according to a project selection result according to a dynamic planning thought, and carrying out a new round of evaluation and selection. The method considers the influence of the project under construction and the arranged project on the power distribution network, can avoid the investment repetition, and has important reference value for actual planning work.

Description

technical field [0001] The invention belongs to the technical field of distribution network construction, and in particular relates to a dynamic selection method for high-voltage distribution network projects based on network analysis. Background technique [0002] The optimization of distribution network construction projects belongs to the problem of operations research. Considering the multi-level, multi-attribute and multi-objective of the problem, the evaluation method is generally used when comparing and selecting multiple projects. The relevant research on evaluation methods mainly focuses on three aspects: establishing the index system, determining the weight of each index and establishing a mathematical model. [0003] There are many comprehensive methods that can be used in the evaluation field, including expert consultation Delphi method (Delphi), analytic hierarchy process (AHP), fuzzy comprehensive evaluation method, data envelopment analysis (DEA), artificial n...
