Problems solved by technology

However, when the AHP method performs a pairwise comparison, if the information is incomplete, the judgment will be uncertain, resulting in a large deviation in the solution accuracy.
The second category is the research on distribution network investment allocation under the constraints of a certain investment amount, which involves multi-objective optimization problems

Embodiment 1

[0114] see figure 1 , a decision-making method of a three-level distribution network investment decision-making system, the decision-making system includes an investment scale decision-making module, an investment direction decision-making module and an investment project decision-making module;

[0115] The decision-making method is based on the data of the State Grid Corporation of China's distribution network from 2014 to 2017 on the operating data of 11 prefectural companies in a province and the year-end summary statistics as the basic data, and the distribution network of the province in 2018 is set The total investment is 18 billion yuan, and the statistics and calculation software are MATLAB and SPSS. Follow the steps below:

[0116] Step 1. Establish an evaluation index system for distribution network investment effectiveness, and divide each index in the system into three categories: positive index, negative index, and moderate index. The index system includes power ...

Abstract

A decision-making method for a three-level distribution network investment decision-making system. The investment scale decision-making module first uses the Logistic growth model to fit the relationship between the comprehensive score of the distribution network construction status and the cumulative investment amount, and predicts the target annual electricity consumption of each region , using a polynomial to fit the relationship between electricity consumption and cumulative investment, to obtain the corresponding cumulative investment, and then carry out regional optimal configuration of distribution network investment according to the cumulative investment, and then the investment direction decision-making module takes the result of regional optimal configuration as distribution network Investment constraints, according to the importance of each investment project attribute to the construction of the distribution network, optimize the configuration of the project attributes, and then use the optimal configuration results of the project attributes as the attribute investment constraints in the investment project decision-making module, and determine the distribution network according to the comprehensive evaluation results of each investment project Investment project optimization model, and finally select the project. This design not only ensures the integrity, coordination and network of distribution network investment, but also conforms to the actual project.

Description

technical field [0001] The invention belongs to the field of distribution network automation, and in particular relates to a decision-making method for a three-level distribution network investment decision-making system. Background technique [0002] In recent years, with the rapid growth of my country's national economy, the demand for electricity in the whole society has continued to increase, and the investment in power grid companies has also continued to increase. Issues of focus. However, at present, problems such as unreasonable capital allocation and poor investment balance of prefecture-level power grid companies in China's provincial-level power grid companies are common. There are problems with arrangements and so on. There is a lot of room for improvement in the investment efficiency of the distribution network. A complete and reasonable distribution network investment decision-making system is very important for power grid enterprises to achieve intensive and...
