Problems solved by technology

In addition, the development and continuous application of gray theory, fuzzy mathematics and set pair analysis have broadened the thinking of multi-attribute decision-making, and produced many methods such as gray relational decision-making method, gray situation decision-making method, fuzzy comprehensive evaluation method, fuzzy analytic hierarchy process and so on. Attribute decision-making methods, such as the fuzzy comprehensive evaluation method, are widely used in the actual comprehensive evaluation, but this method has the following shortcomings: 1) The membership function is difficult to determine, and the subjective randomness is strong, which increases the decision-making process. 2) The selection of fuzzy operators is difficult, and many fuzzy operators cannot make full use of known information, and their objective applicability is weak

Abstract

The invention relates to a two-stage decision-making optimization method and system for a power network project, which is characterized in that the method comprises the following steps of analyzing factors influencing the sequencing of the power network project, and constructing an evaluation index system for the sequencing of the power network project; according to the evaluation index system ofpower grid project optimization ranking, establishing the power grid project optimization ranking model based on matter-element extension; according to the optimal sequencing model of power grid projects, selecting the power grid projects that meet the requirements of corresponding evaluation indexes, and obtaining the basic information of the selected power grid projects; according to the goal ofpower grid development, establishing the auxiliary decision-making model of power grid development based on Weingartner in advance, and determining the constraint conditions of power grid project; according to the pre-established auxiliary decision-making model of power network development and the screened power network items and their basic information, the optimal power network items or the combination of power network items based on the power network investment quota are determined. The method and the system can be widely applied in the decision-making optimization field.

Description

technical field [0001] The invention relates to a two-stage decision-making optimization method and system for a power grid project, belonging to the field of decision-making optimization. Background technique [0002] The power industry is a pillar industry in modern society. All production activities in modern society are inseparable from stable power supply and support. The main links of the power industry include power generation, transmission and distribution, and the power grid undertakes the task of power transmission and distribution. It involves investment, construction and operation and maintenance of a large number of projects. Power grid projects require a huge amount of investment, and the investment payback period is long and there are many uncertain factors, so it is difficult to obtain income in the short term. However, the investment decision-making of power grid projects affects the long-term stable operation of power grid enterprises. Therefore, how to rea...
