Problems solved by technology

A single project evaluation can only focus on the experience and lessons of the project itself, and the promotion of evaluation conclusions is limited, and it is not suitable for raising the level of macro control to reflect investment results
The evaluation conclusions are mostly applicable to the "review" of the project, and have limited guidance for the next investment decision-making
In addition, the parameter indicators of the project and equipment in the basic data cannot be connected, which affects the objectivity and accuracy of the evaluation conclusion
The one-time fixed time-point evaluation conclusion has limitations, and cannot objectively reflect the operating efficiency and benefits of the entire project cycle, and cannot dynamically explore the changing law of investment effects

Embodiment 1

[0063] This embodiment proposes a simulation method for precise investment decision-making in power grid projects based on full-element data mining.

[0064] In this embodiment, firstly, all elements of influencing factors are mined from macro, meso and micro levels, and a large number of factors that may affect power grid investment are screened out. Combining macro factors and meso factors, system dynamics is used to establish an investment scale prediction model , and modify the investment scale according to the grid income coefficient. At the same time, the grid project investment evaluation index system is established based on micro-factors, and the grid reserve project is evaluated. Then, with the investment scale as the constraint, the genetic algorithm is used to optimize the grid project investment, so as to realize the precise investment of the grid project. The software tools involved mainly include EXCEL, Vensim and Matlab.

Abstract

The invention discloses a power grid engineering accurate investment decision simulation method and system based on total element data mining, and solves the problem that a decision result is not accurate enough due to the fact that factors considered by a traditional investment decision simulation technology are not comprehensive. According to the method, a Frisch comprehensive analysis method isadopted, multi-level full-factor influence factor mining analysis is performed from macroscopic, mesoscopic and microscopic aspects, an investment scale prediction model is established by utilizing system dynamics in combination with macroscopic factors and mesoscopic factors, and the investment scale is corrected according to a power grid income coefficient. A power grid project investment evaluation index system is established according to microcosmic factors, a power grid reserve project is evaluated, then power grid project investment optimization is performed by adopting a genetic algorithm with the investment scale as a constraint, and the method can be used for future power grid project investment decision making and provides technical support for accurate investment of power gridprojects.

Description

technical field [0001] The invention relates to the technical field of auxiliary decision-making for power grid engineering investment, in particular to a simulation method and system for precise investment decision-making in power grid engineering based on full-element data mining. Background technique [0002] From the perspective of the macro situation, although my country's economy still has downward pressure, it is relatively controllable. The focus of macroeconomic regulation has shifted from pursuing economic growth to emphasizing the quality of economic growth, and the economic structure has continued to be optimized. In response to the downward pressure on the economy, the state has issued a series of major decisions and deployments centering on stabilizing growth, promoting reform, adjusting structure, and benefiting people's livelihood. Under the current situation of continuous fluctuations in electricity consumption, the state requires increased investment in pow...
