Problems solved by technology

At present, a multi-objective model is often established for the decision-making problem of power transmission and transformation projects. Since there are too many objective functions in the comprehensive decision-making model of power transmission and transformation projects, and some objective functions need to be satisfied first, the common multi-objective optimization algorithm is very difficult. It is difficult to solve such a problem
At present, most of the literature solves by simplifying the mathematical model and using multi-objective optimization algorithm, but this will inevitably lead to incomplete evaluation results, which will affect the implementation of actual projects.

Embodiment

[0047] The effectiveness of the method of the present invention is verified by simulation calculation using a power grid in a supply area as an example. The original system contains 20 nodes and 3 generators (rectangles). Among them, the letters A to F represent the nodes of the 500kV voltage level, and the numbers 1 to 15 represent the nodes of the 220kV voltage level. The supply area originally had a 500kV substation (node ​​A) and three 1000MVA main transformers with a low capacity-to-load ratio, and when one main transformer is lost, part of the load will be lost, and the power supply capacity is insufficient, so the transformer capacity needs to be increased. In view of this, the project considers to choose to expand the A substation (with the newly built node B 220kV switch station) or build the B substation. See Table 1 for information about the new line selected. For the original topology see image 3 .

Abstract

Disclosed is a power transmission and transformation engineering project establishment decision-making method based on two-phase double-layer multi-target optimization. The method is based on an indicator model during actual complex electric power system power transmission and transformation engineering project establishment decision-making, problems are divided into two phases, i.e., project establishment and decision making, each indicator of security I type is taken as a target function of a lower layer multi-target model, such indicators as security II type, economy, environmental friendliness, adaptability, compatibility and the like are taken as the target function of an upper layer multi-target model, under the condition that the lower layer multi-target model is satisfied, the upper layer multi-target model is optimized, mutual iteration is performed on the upper layer multi-target model and the lower layer multi-target model, and an optimal power transmission and transformation engineering construction scheme is obtained, such that the problem of too many indicators of the security I type which need priority satisfaction is well handled and effectively solved.

Description

technical field [0001] The invention relates to a two-stage double-layer multi-objective optimization-based decision-making method for power transmission and transformation projects, and belongs to the technical field of power system planning. Background technique [0002] With the rapid development of my country's economy and the continuous expansion of the power system, people's requirements for the safety, reliability, and quality of power supply are also increasing. It is bound to require a large number of power transmission and transformation projects to be invested in the construction of the power grid. In response to the demand for power grid construction, a large number of power transmission and transformation projects are reported every year. Some of these projects are needed for power grid construction, and they can solve a certain defect of the power grid, but the other part is unnecessary, or the reported scheme is not optimal, and needs to be replaced with a bet...
