Compared with the traditional systems in the past, the new energy systems have the characteristics of a large number of renewable energy access, complex and changeable energy supply methods, and complex characteristics of changes in the source and load ends of the system, which have derived a variety of different system categories and forms such as regional energy and microgrids. The characteristics of the new energy system have put forward higher requirements for its scoring method. The scoring method for the traditional system can no longer adapt well to the new energy system. How to correctly and quickly score the quality and benefits of the new energy system has become a problem that needs to be solved urgently.

[0003] Among the existing scoring methods for new energy systems, one method is to score new energy systems for individual indicators through standard documents, but this method is too simple and cannot accurately score new energy systems; another existing scoring method is to organize an expert review meeting and score new energy systems through expert scoring. This method is inefficient and complicated in scoring new energy systems due to its complex process and subjectivity. Therefore, there is an urgent need for a new energy system scoring method and system to solve the defects of the existing technology. Summary of the invention

The present invention avoids the complicated process and subjective judgment of expert review and scoring by calculating the absolute performance score and the relative performance score, thereby greatly improving the efficiency and accuracy of the scheme scoring. By calculating the index values ​​through the historical operation data of the energy system, the scoring of the scheme is based on the real system operation data, so that it can be scored from multiple angles, which improves the accuracy of the scheme scoring; by correcting the project index values, the rationality of the calculation of the performance score is improved, so that the performance score is more in line with the actual operation of the energy system, thereby improving the accuracy of the optimal system scheme, and making the energy system operation based on the optimal system scheme more efficient and in line with the standards.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] With the continuous deepening and development of research and application of new energy, the energy system continues to transform and develop. Compared with the traditional system in the past, the new energy system has the characteristics of a large amount of renewable energy access, complex and changeable energy supply methods, and complex changes in the source and load ends of the system. It has derived a variety of different system categories and forms such as regional energy and microgrids. The construction objectives and expected benefits of the energy system are diverse and personalized. Therefore, the requirement for multi-objective comprehensive evaluation has arisen at the level of system solution evaluation.

[0064] The establishment of a multi-objective comprehensive evaluation method is the basic premise for optimizing new energy system solutions and ensuring the realization of system benefits, while the diversified and customized characteristics of new energy systems put forward higher requirements for comprehensive system evaluation. Scientifically evaluating the characteristics and benefits of new energy systems will help improve the level of system solutions, the rationality of project planning, construction, and operation, and the efficiency of energy system operation.

[0065] The evaluation methods currently applied to new energy systems are: the first method is to conduct single indicator evaluation based on the indicator assessment standards proposed in the existing standard documents. However, the standard specifications for the unconventional and innovative indicators involved in the evaluation process of this method are not systematic, and the policy goals are macroscopic. It is usually difficult to ensure that each indicator used in the evaluation process can obtain standard numerical references or related supporting materials. Therefore, at the level of single indicator evaluation, it is often difficult to determine the evaluation standards and promote the evaluation process.

[0066] The second existing method is to hold an expert review meeting to evaluate the project plan. However, this method is highly influenced by the subjective cognitive factors of the expert group members, usually lacks a relatively clear scoring standard and thus produces information bias; it is easy to ignore the impact of objective and force majeure factors such as the project location, system construction conditions, and regional market environment on project performance; when the evaluation is conducted in the form of a meeting discussion, it is easy for the evaluation results to be not objective due to reasons such as following the vote.

[0067] In the current field of energy system scoring, on the one hand, with the development of related technologies and the promotion of equipment, how to scientifically evaluate the quality and efficiency level of new energy systems is an important issue that needs to be solved urgently; on the other hand, from the perspective of technology promotion, new energy systems as urban infrastructure construction are still in their infancy, and all sectors of society have insufficient cognition, lack of experience, and lack of coordination on new energy systems, which makes the construction of new energy systems simplistic and one-sided, resulting in a waste of social resources. It can be seen that the evaluation of new energy systems is a multi-objective evaluation problem that needs to consider a variety of innovative and unconventional evaluation factors. The current evaluation method system for new energy systems has not yet taken shape, so it is of great significance to develop a set of scoring methods suitable for new energy systems.

[0110] It should be noted that the preset threshold is a similarity score of 0.5 or more, and the number of benchmark projects is more than five. When the number is insufficient, the research work is re-conducted to obtain more benchmark projects with a similarity score of 0.5 or more. The final number of benchmark projects is M, and the project indicator values ​​of the benchmark projects are [Sd1, Sd2, …, Sd M ].

[0182] For the i-th system solution to be evaluated, its first relative performance score is Sca i , the second relative performance score is Scb i , with a relative performance score of Sc i ,in, Then the relative performance scores of the system solutions to be evaluated are [Sc0, Sc1, …, Sc N ].

[0183] The absolute performance scoring process proposed in this embodiment takes into account both the absolute value distribution and the sample value distribution of the standard reference value. The standardized process of the relative scoring method adopts both the root method and the sum method, thereby improving the objectivity of the evaluation results.

[0184] Step S105: Obtaining an optimal system solution according to the absolute performance score and the relative performance score.

[0185] In an optional embodiment, obtaining the optimal system solution according to the absolute performance score and the relative performance score specifically includes:

[0186] For the i-th system solution to be evaluated, its absolute performance score is Ss i , with a relative performance score of Sc i ;

[0187] According to the absolute performance score and the relative performance score, the final score of the i-th system solution to be evaluated is Se i ,in,

[0188] When only one system solution is scored, that is, when there is only one system solution to be evaluated, the difference between the final score of the system solution to be evaluated and the benchmark solution is compared; and the optimal system solution is determined according to the difference;

[0189] When multiple system solutions are scored, that is, when there are multiple system solutions to be evaluated, the system solution to be evaluated with the highest final score is selected as the optimal system solution.

[0190] It should be noted that the final score difference between the system solution to be evaluated and the benchmark solution; and determining the optimal system solution according to the difference, specifically includes:

[0191] Calculate the final score of the system solution to be evaluated by A% higher than the benchmark solution;

[0192] When A% is: 0-10% is feasible, 10%-20% is good, and more than 20% is excellent;

[0193] If it is excellent, the system solution to be evaluated is recorded as the optimal system solution.

[0194] This embodiment takes into account both absolute performance and relative performance, ensuring that the evaluation process simultaneously considers the performance level of the system solution in the industry field, as well as the impact of force majeure and personalized factors such as project location, construction conditions, and market factors on project performance, to avoid the solution performance being underrated due to objective difficulties or overestimated due to a favorable environment.

[0195] This embodiment constructs the index values ​​of the system solution to be evaluated and the alternative benchmarking projects through the historical operation data of the energy system, and then obtains the absolute performance score and relative performance score of the system solution to be evaluated, thereby realizing the scoring of the system solution to be evaluated and the screening of the optimal system solution. This embodiment avoids the complicated process and subjective judgment of expert review and scoring by calculating the absolute performance score and the relative performance score, thereby greatly improving the efficiency and accuracy of the scheme scoring. By calculating the index values ​​through the historical operation data of the energy system, the scoring of the scheme is based on the real system operation data, so that it can be scored from multiple angles, which improves the accuracy of the scheme scoring; by correcting the project index values, the rationality of the calculation of the performance score is improved, so that the performance score is more in line with the actual operation of the energy system, thereby improving the accuracy of the optimal system solution, and making the operation of the energy system based on the optimal system solution more efficient and in line with the standards.
