Reserved project optimization method based on contribution degrees of power grid effects

Abstract

The invention discloses a reserved project optimization method based on contribution degrees of power grid effects. The method comprises the steps of S1, comprehensively collecting power grid reservedproject quantitative evaluation related data information, and establishing a reserved project evaluation index system based on the power grid effects; S2, according to the evaluation index system inthe step S1, analyzing and obtaining a quantitative calculation method for indexes; S3, performing calculation according to the evaluation index system and the quantitative method in the previous step, and by applying a principle of combining subjective and objective weights, determining a weight calculation method for the indexes in comprehensive contribution degree calculation; S4, according toa weight calculation formula in the step S3, carrying out single target optimization by adopting a particle swarm algorithm, and determining optimal weights; S5, according to the optimal weights in the step S4, calculating comprehensive contribution degrees of reserved projects, and carrying out dynamic sorting on the reserved projects by considering the influence on other reserved projects aftercompletion of the reserved projects in combination with the investment of the reserved projects, thereby completing the optimization of the reserved projects.

Description

technical field [0001] The invention relates to a method for optimizing a power grid project, in particular to a method for quantitatively evaluating and optimizing a reserve project based on the contribution degree of power grid performance. Background technique [0002] The marketization of electricity and the gradual deepening of the reform of the power enterprise system, the volatility of new energy power generation and the diversification of the main body of the external transmission project, coupled with the problems of large investment scale and long recovery time of the original power grid construction project, make the status of economic factors in decision-making At the same time, new features such as the complexity of decision-making factors, the increase of uncertain influencing factors and the diversification of decision-making subjects all pose new problems and challenges for the construction evaluation decision-making of power grid reserve projects.

AI Technical Summary

Problems solved by technology

[0005] First, under the influence of traditional thinking, only the feasibility and necessity analysis from the perspective of technology and safety is emphasized for power grid construction projects, and the analysis from the economic perspective is relatively diluted;

[0006] Second, there is a lack of analysis of uncertain influencing factors in the process of power grid project construction, as well as quantification of these influencing factors;

[0007] Third, the evaluation content and methods and dynamic optimization management of the power grid construction project reserve library need to be further improved;

[0008] Fourth, there is a lack of investment optimization portfolio research on the simultaneous implementation of multiple projects in the entire regional power grid

[0009] At present, the research on project evaluation mainly focuses on the post-evaluation work of projects that have been put into operation using methods such as fuzzy hierarchical analysis, expert scoring, and quantitative analysis of indicators. After the completion of the function and effect on the entire power grid, it is unable to provide technical support for the storage of reserve projects and inclusion in the investment plan
