Embodiment Construction

[0021] Below in conjunction with specific embodiment the present invention is described in further detail:

[0022] A method suitable for evaluating the weight of factors affecting power grid planning decision-making, the steps are as follows:

[0023] (1) Obtain the impact factor through the Delphi method

[0024] The Delphi method uses back-to-back communication to consult the forecast opinions of the members of the expert group. After several rounds of consultation, the forecast opinions of the expert group tend to be concentrated, and finally a conclusion close to the actual situation is made. The Delphi method is based on systematic procedures and adopts the method of anonymous expression of opinions, that is, team members are not allowed to discuss with each other, do not have horizontal contact, and can only have relationships with investigators. Fill in the questionnaire repeatedly and gather the opinions of the questionnaire completers. Consensus and collection of op...

Abstract

The invention discloses a method suitable for evaluating weights of factors affecting power network planning decision-making. The steps are as follows: (1), obtaining influence factors through a Delphi technique method, and according to the understanding of each expert in the factor affecting power network development decision-making, determining each specific factor affecting the decision-making in a power network planning process; (2), through a two-dimensional matrix method, defining the influence probability grade, the influence value grade, the influence grade and the attention grade of each influence factor in step (1), and defining different values for different grades; and (3), for the values corresponding to the influence probability grade, the influence value grade, the influence grade and the attention grade of each influence factor, through a Borda sequence value method, calculating the Borda value of the influence factor, and sequencing the Borda value of each influence factor so as to finish weight calculation. The method provided by the invention realizes conversion of qualitative analysis of the factors affecting the power network planning decision-making into quantitative calculation, and is more scientific and more reasonable.

Description

technical field [0001] The invention relates to a decision-making method in the field of grid planning and construction, in particular to a method suitable for evaluating the weight of factors affecting grid planning decision-making. Background technique [0002] In the process of power grid planning, the methods commonly used now are: [0003] (1) Analytic Hierarchy Process (Analytic Hierarchy Process referred to as AHP) [0004] This method is a decision-making method that decomposes the elements that are always related to decision-making into goals, criteria, programs, etc., and conducts qualitative and quantitative analysis on this basis. Its disadvantages are that this method cannot provide new solutions for decision-making, the data statistics are large when there are too many indicators, and the weight is difficult to determine. [0005] (2) Principal Component Analysis [0006] This method hopes to use fewer variables to explain most of the variables in the origin...
