The comprehensive score refers to scoring information on the whole investment project.
Specifically, the terminal determines a scoring index of each investment project aiming at the technical improvement of the power grid, and performs scoring processing on project data of each investment project according to the scoring index to obtain a comprehensive score of each investment project. The project data may be present information of an investment project, project basic data, or the like.
Step S102, screening the investment projects of the power grid technical improvement according to the comprehensive scores of the investment projects and the initial investment sum of the power grid technical improvement to obtain candidate investment project combinations of the power grid technical improvement.

Step S103, updating the initial investment sum according to the total score of the candidate investment project combination and the historical total score of the historical investment project combination of the power grid technical improvement to obtain the updated investment sum of the power grid technical improvement.
Wherein, the historical investment project combination refers to a target investment project combination of a historical time period. For example, the historical investment portfolio may be a target investment portfolio for the last year.
Specifically, the terminal determines whether to increase the initial investment sum or decrease the initial investment sum according to the magnitude relation between the total score of the candidate investment project combination and the historical total score of the historical investment project of the grid technical improvement, and then the terminal obtains the updated investment sum of the grid technical improvement.
Step S104, screening the investment projects of the technical improvement of the power grid according to the updated investment sum to obtain an updated investment project combination.
Specifically, after obtaining the updated investment sum, the terminal may screen out the individual investment items within the updated investment sum again from the investment items according to the screening priority of the investment items, and then combine to obtain the updated investment item combination.
Step S105, carrying out project classification processing on the updated investment project combinations to obtain target investment project combinations for technical improvement of the power grid.
Specifically, the terminal obtains project specialty categories, specialty scales and project level solution problems of the power grid from the project database. And carrying out item classification processing on the updated investment item combination according to the item specialty category, specialty scale and item level solution problem to obtain target investment item combinations of all specialty levels corresponding to the item level solution problem, so that the obtained target investment item combinations meet the requirements of the power grid specialty item levels, and the rationality of the obtained target investment item combinations is improved.
In the processing method of the investment projects for the technical improvement of the power grid, the comprehensive score of each investment project for the technical improvement of the power grid is determined; screening the investment projects of the technical improvement of the power grid according to the comprehensive scores of the investment projects and the initial investment sum of the technical improvement of the power grid to obtain candidate investment project combinations of the technical improvement of the power grid; then updating the initial investment sum according to the total score of the candidate investment project combination and the historical total score of the historical investment project combination of the power grid technical improvement to obtain the updated investment sum of the power grid technical improvement; screening the technically improved investment projects of the power grid according to the updated investment sum to obtain updated investment project combinations; and carrying out project classification treatment on the updated investment project combinations to obtain target investment project combinations for technical improvement of the power grid. By adopting the method, the initial investment sum can be updated by screening out the candidate investment combinations, the updated investment project combinations can be screened out by updating the optimized updated investment combinations, the allocation rationality of the investment sum is improved, the decision accuracy of the technical improvement investment projects of the power grid is improved, and finally, the updated investment project combinations are classified from the professional category of the power grid, so that the target investment project combinations in the professional scale level are obtained, and the decision accuracy of the technical improvement investment projects of the power grid is further improved.
In one embodiment, as shown in fig. 2, step S103, updates the initial investment sum according to the total score of the candidate investment project combination and the historical total score of the historical investment project combination of the grid technical improvement to obtain the updated investment sum of the grid technical improvement, which specifically includes the following contents:
step S201, determining the investment scale adjustment coefficient of the initial investment sum according to the total score of the candidate investment project combination and the historical total score of the historical investment project combination.
Wherein the total score refers to a project score calculated by the composite score of each investment project in the investment project portfolio (such as a candidate investment project portfolio or a historical investment project portfolio).
Specifically, the terminal first determines a total score for the candidate portfolio of investment items and a historical total score for the historical portfolio of investment items. Then, the terminal divides the total score of the candidate investment project combination and the historical total score of the historical investment project combination to obtain an investment scale adjustment coefficient of the initial investment total.
The investment scale adjustment coefficient can be calculated by the following formula: investment scale adjustment factor = total score of candidate portfolios/(historical total score of historical portfolios).
Step S202, the initial investment sum is adjusted through the investment scale adjustment coefficient, and the updated investment sum of the technical improvement of the power grid is obtained.
Specifically, the terminal performs weighting treatment on the initial investment sum through the investment scale adjustment coefficient, and takes the result obtained by the weighting treatment as the updated investment sum of the technical improvement of the power grid.
The updated investment sum can be calculated by the following formula: updated investment sum = initial investment sum x investment scale adjustment factor.
As can be seen from the calculation formula of the investment scale adjustment coefficient, when the total score of the candidate investment project combination is higher than the historical total score of the historical investment project of the technical improvement of the power grid, the investment scale of the technical improvement of the power grid is increased, namely the updated investment total is larger than the initial investment total; when the total score of the candidate investment project combination is smaller than the historical total score of the historical investment project of the technical improvement of the power grid, the investment scale of the technical improvement of the power grid is reduced, namely the updated investment sum is smaller than the initial investment sum.
In this embodiment, the investment scale adjustment factor of the initial investment sum is determined by the total score of the candidate investment project portfolio and the historical total score of the historical investment project portfolio; and the initial investment sum is adjusted through the investment scale adjustment coefficient to obtain updated investment sum of the technical improvement of the power grid, and the investment sum is accurately adjusted according to the actual change condition of the total score by combining the historical total score and the total score of the current candidate investment project combination, so that the obtained updated investment sum is more accurate, and the configuration rationality of the investment sum is improved.
In one embodiment, in the step S103, before updating the initial investment sum according to the total score of the candidate investment project portfolio and the historical total score of the historical investment project portfolio of the grid engineering improvement, the method further includes: obtaining comprehensive scores of all candidate investment projects in the candidate investment project combination; and carrying out weighted average treatment on the comprehensive scores of the candidate investment projects to obtain the total score of the candidate investment project combination.
Specifically, the terminal may obtain a composite score for each candidate investment item within the candidate investment item portfolio; the comprehensive scores of the candidate investment projects are weighted and averaged, and then the terminal obtains the total score of the candidate investment project combination; similarly, the terminal may perform a weighted average process on the composite scores of each of the historical investment items in the historical investment item portfolio to obtain a historical total score for the historical investment item portfolio. If the historical total score is stored in the historical investment project combination in the past, the terminal can also directly inquire to obtain the historical total score.
In practical applications, the total score of the candidate investment projects can also be calculated by the following formula: total score of candidate investment project portfolio = Σ (single project investment x composite score of candidate investment projects)/(Σ single project investment).
In this embodiment, by obtaining a composite score for each candidate investment item in the candidate investment item portfolio; and carrying out weighted average processing on the comprehensive scores of the candidate investment projects to obtain the total score of the candidate investment project combination, and reasonably acquiring the total score of the candidate investment project combination and the historical total score of the historical investment project combination, so that the terminal in the subsequent step calculates an investment scale adjustment coefficient based on the total score and the historical total score, thereby realizing the updating of the initial investment total.
In one embodiment, the step S101 is to determine a comprehensive score of each investment project of the grid technical improvement, which specifically includes the following contents: carrying out scoring mapping treatment on item data of each investment item through an item scoring mapping model to obtain single scores of each investment item; and fusing the single scores of the investment projects to obtain the comprehensive score of each investment project.
The project score mapping model is a model for mapping and obtaining single scores of investment projects according to project data of the investment projects. A single score refers to the score of an investment item in a single evaluation dimension.
Specifically, the terminal trains and obtains a project scoring mapping model according to comprehensive scores, evaluation dimensionality and scoring scores, scoring weights and project data of the historical investment projects. And the terminal inputs the project data of each investment project into a project scoring mapping model so as to obtain a single score of each investment project under each evaluation dimension according to the project data of each investment project by the project scoring mapping model. The terminal fuses the single scores of the investment projects, and can directly add all the single scores or can weight the single scores according to the score weight so as to obtain the comprehensive scores of the investment projects.
In practical application, the comprehensive score of the historical investment project can be obtained through calculation in the mode provided in the step S101, and can also be directly filled in by project responsible personnel with the technical improvement of the power grid according to project planning or investigation. The evaluation dimension and scoring score are based on the index system and project preference method. The scoring weights may be determined by expert scoring and analytic hierarchy processes. For example, the evaluation dimension may include three aspects of technical effect, economic benefit, and other effects.
The technical effects are as follows: for quantifying the contribution of investment projects to technical effects. Filling index values for metering automatic terminal coverage rate, automatic meter reading rate, millions of customer complaint rate and electricity selling electronic settlement rate according to project planning or scientific research respectively, and dividing the index values by the implementation cost of investment projects to obtain the benefit-investment ratio of the index; and (3) for the practical evaluation score of the metering automation system, filling in the index value according to project planning or investigation, obtaining the sorting score of the index based on the sorting of the index, and dividing the sorting score by the implementation cost of the investment project to obtain the benefit-investment ratio of the index. And finally, obtaining index scores by adopting a normalization method for each index, and calculating single scores of technical effects of investment projects by combining index weights.
Economic benefit: for quantifying the contribution of investment projects to economic benefits. For the average retirement period and the electric charge error rate of the metering terminal equipment, filling in index values according to project planning or scientific research respectively, and dividing the index values by the implementation cost of investment projects to obtain the benefit-investment ratio of the index; and filling in index values according to project planning or scientific research for obtaining the electric power index, obtaining the sorting score of the index based on the sorting of the index, and dividing the sorting score by the implementation cost of the investment project to obtain the benefit-investment ratio of the index. And finally, obtaining index scores by adopting a normalization method for each index, and calculating the single scores of the economic benefits of the projects by combining the index weights.
Regarding the scoring weight, the technical effect is 70% of the weight of the composite score, and the economic benefit is 30% of the weight of the composite score. Further, the weight ratio of the evaluation index with finer granularity in each evaluation dimension may include: the coverage rate and the automatic meter reading rate of the metering automatic terminal respectively account for 20% of the weight of the technical effect; millions of customer complaints account for 30% of the technical effect weight; the electricity selling electronic settlement rate and the metering automation system are practical, respectively account for 15% of the technical effect weight, the average retirement period and the electricity fee error rate of the metering terminal equipment respectively account for 40% of the economic benefit weight, and the obtained electric power index accounts for 20% of the economic benefit weight.
In the embodiment, through an item scoring mapping model, scoring mapping processing is carried out on item data of each investment item, so as to obtain single scores of each investment item; the single scores of the investment projects are fused to obtain the comprehensive score of each investment project, and reasonable acquisition of the comprehensive score of each investment project is realized through the project score mapping model without relying on experts to score the project. In addition, the comprehensive scores of the investment projects are determined through the single scores of multiple evaluation dimensions, so that the comprehensiveness and the accuracy of the comprehensive scores of all the investment projects can be improved, and the target investment project combination of the power grid technical improvement can be determined more comprehensively and accurately.
In one embodiment, the step S102 is to screen the investment projects of the grid improvement according to the comprehensive score of each investment project and the initial investment sum of the grid improvement, so as to obtain a candidate investment project combination of the grid improvement, which specifically includes the following contents: sequencing the investment projects according to the comprehensive scores of the investment projects to obtain project sequencing results of the investment projects; screening candidate investment projects meeting the initial investment sum of the technical improvement of the power grid from all the investment projects according to the project sequencing result; and combining the candidate investment projects to obtain a candidate investment project combination.
Specifically, the terminal can sort the investment projects according to the sequence from large to small of the comprehensive scores of the investment projects to obtain the project sorting result of the investment projects; determining screening priority of each investment project according to the project sequencing result; and screening candidate investment projects from all the investment projects based on screening priority within the range of the initial investment sum of the technical improvement of the power grid.
