Power distribution network planning effect evaluator based on stacked auto-encoders

Abstract

The invention relates to a stacked auto-encoder-based power distribution network planning effect evaluator, which comprises the following steps of: 1, sorting common power distribution network planning effect indexes, and distinguishing according to two dimensions of power supply reliability and investment benefit; 2, constructing a power distribution network planning effect index system based on correlation degree, and selecting an index with the strongest correlation degree as a power distribution network planning effect index by calculating the correlation degree between a power distribution network planning index and power supply reliability and economic benefits; 3, generating a large number of planning scheme samples in MATLAB simulation software, and calculating a power distribution network planning effect result under a given condition; 4, training and generating a power distribution network planning effect evaluator to realize rapid evaluation; the method has the advantages that the planning effect result is quickly obtained, the optimal planning scheme is obtained, and the problems that a traditional model calculation method is large in supporting data volume and difficult to apply in practice, so that the planning effect index mainly depends on experience calculation, and the planning decision requirement cannot be met are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of distribution network planning, and in particular relates to a distribution network planning effectiveness evaluator based on a stacked autoencoder. Background technique [0002] As power companies gradually shift their construction centers to the construction of distribution networks, distribution network planning has become a key link in the safe, reliable, and economical operation of power grids. The analysis of distribution network planning effects is a core part of distribution system evaluation. A reasonable and practical distribution network planning effectiveness evaluation index system can become an important basis for the feasibility of planning schemes, and is of great significance to the authenticity and data validity of distribution network planning effectiveness analysis. Urban medium-voltage distribution network Due to the characteristics of complex structure and large amount of basic data, ...
