Abstract

The invention discloses a method for predicting the operation and maintenance cost of a distribution network based on a genetic algorithm and a support vector machine. The relationship between the operation and maintenance cost of the distribution network and influence factors is difficult to be expressed in a linear manner. The method comprises the steps that 1) genetic algorithm analysis is performed on influences factors of the operation and maintenance cost of the distribution network, that is, training parameters of a distribution network operation and maintenance cost prediction model are determined by using the genetic algorithm; 2) a support vector machine distribution network operation and maintenance cost prediction model is built, that is, the support vector machine is used to act as a prediction model for the operation and maintenance cost of the distribution network by using a property of infinitely approaching to the nonlinear continuous function relationship of the support vector machine on the basis of the genetic algorithm; and 3) the operation and maintenance cost of the distribution network is predicted based on the genetic algorithm and the support vector machine. According to the method, the operation and maintenance cost of the distribution network can be estimated accurately and reasonably, and power grid enterprises are facilitated to effectively manage and control the operation and maintenance cost of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power grid operation cost management, and relates to a method for predicting distribution network operation and maintenance costs based on a genetic algorithm and a support vector machine. Background technique [0002] The operation and maintenance fee of distribution network is an important part of the investment of power grid enterprises. In order to formulate the best investment strategy, it is necessary to accurately and reasonably estimate the operation and maintenance fee of distribution network. However, the operation and maintenance fee of the distribution network is affected by various factors such as society, economy, policy, and resources, and the mechanism of each factor is complex, which makes it difficult to express the relationship between the operation and maintenance fee of the distribution network and the influencing factors in a linear manner. Contents of the invention [0003] The te...
