[0089] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0090] my country's cognition of the term "energy power" and its willingness to develop into an energy power have gone through a development process from awareness by a few people to general consensus, and from a little vague to clear and firm. The term "energy power" has been proposed or used by many government officials, energy experts, scholars, and media personnel, but it is impossible to accurately verify the time when China first proposed this concept. According to incomplete statistics, it can be traced back to at least July 15, 2011, when Zhu Weitao, a senior economist of Yunnan Power Grid Company, published an article on "China Energy Network" entitled "How to Transform from an Energy Power to an Energy Power", pointing out that my country's problem of being big but not strong is very prominent. Subsequently, the National Energy Science and Technology "12th Five-Year Plan" released on December 5, 2011 and the National Energy "12th Five-Year Plan" released on January 1, 2013 showed that many gaps restricted my country's transition from an "energy power" to an "energy power", and at the same time, my country faced a rare historical opportunity to transform from an energy power to an energy power. In 2012, Zhang Guobao, then director of the National Energy Administration, proposed the "energy power" strategy. Driven by these strategies, the concept of "energy power" has been mentioned more and more widely in China and gradually become clearer. On October 30, 2017, China Electric Power News published an article titled "The Great Leap From an Energy Power to an Energy Power", which looked forward to China's leap from an energy power to an energy power. On November 1, 2017, China Electric Power News published another article titled "Keep in Mind the Mission and Build a Socialist Modern Energy Power in an All-Round Way", emphasizing that the energy development mission of the new era is to build a socialist energy power in an all-round way. In 2021, the Central Economic Work Conference clearly put forward the goal of deepening the energy revolution and accelerating the construction of an energy power, which marked that "energy power" was officially proposed in China's central-level meetings and documents. Since then, "energy power" has become a hot topic and focus of research by Chinese government officials, energy experts, scholars, media professionals, and others in the past two years.

[0091] In order to construct a comprehensive and scientific energy power evaluation index system and achieve the purpose of quantitatively evaluating energy powers, the embodiments of the present invention provide a method and device for constructing an energy power index system and determining an energy power index.

[0092] Example

[0093] The embodiment of the present invention provides a method for constructing an energy power indicator system, the process of which is as follows: Figure 1 As shown, the following steps are included:

[0094] Step S1: Based on the energy security dimension and the expansion of the connotation of energy security, determine several first-level indicators of the target country, including production, supply, consumption, environment, technology, management and international;

[0095] Step S2: According to the content corresponding to each first-level indicator, determine a number of second-level indicators under each first-level indicator;

[0096] Step S3: Refine the content corresponding to each secondary indicator, and determine a number of tertiary indicators under each secondary indicator. The data of the tertiary indicators are determined by direct acquisition, calculation or qualitative evaluation;

[0097] Step S4: constructing a module for constructing an energy power indicator system based on the plurality of primary indicators, the plurality of secondary indicators under each primary indicator, and the plurality of tertiary indicators under each secondary indicator.

[0098] In order to comprehensively and scientifically evaluate the comprehensive strength of a country or economy in the field of energy and achieve quantitative purposes, it is necessary to build an energy power indicator system, which is also called an energy power evaluation indicator system. First, it is necessary to build the overall framework of the energy power indicator system. The overall goal of the overall framework is the energy power evaluation indicator system. There are three levels of indicator systems to evaluate this overall goal: primary indicators, secondary indicators, and tertiary indicators.

[0099] In some optional embodiments, the above step S1 constructs the first-level indicators of the energy power evaluation index system. There are 7 first-level indicators, namely production, supply, consumption, environment, technology, management and international. These first-level indicators basically cover all aspects of the energy system and can comprehensively evaluate the degree of energy power. Among them, the first-level indicators of production, supply, consumption and environment can basically evaluate energy security. The first-level indicators of technology, management and international can be regarded as the expansion of the connotation of energy security by energy powers, and the former is wider than the latter. On the basis of ensuring energy security, whether a country can be called an energy power, its international influence is an important indicator, which shows its energy status in the international arena. In addition, whether a country can develop into an energy power in the future, its scientific and technological capabilities and management capabilities play a key role. Especially for countries with poor oil and gas resources, the development of science and technology is an important channel for them to develop into energy powers.

[0100] In some optional embodiments, the second-level indicators of the energy power evaluation index system are constructed. The second-level indicators are specific support for the first-level indicators. The above step S2 can be implemented in the following ways:

[0253] Table 8:

[0254]

[0255] In some optional embodiments, the energy power indicator system constructed in step S4 is referenced Figure 2 shown.

[0256] Based on the aforementioned method for constructing an energy power index system, the present invention also provides a method for determining an energy power index, the process is as follows: Figure 3 As shown, the following steps are included:

[0257] Step S31: obtaining data of several third-level indicators of each country in the energy power indicator system, and generating a decision matrix; the energy power indicator system is constructed by the aforementioned energy power indicator system construction method;

[0258] Step S32: normalizing the decision matrix, and determining the weight value of each third-level indicator according to the normalized decision matrix;

[0259] Step S33: Determine the energy power index of each country according to the weight value of each third-level indicator and the normalized data of each third-level indicator.

[0260] According to the established energy power indicator system, the energy power index is calculated based on the multi-criteria decision making method (MCDM method) to achieve the purpose of quantitative evaluation of energy power.

[0261] MCDM is a decision-making method for dealing with multiple decision criteria or objectives. In many practical decision-making problems, decision makers often need to consider multiple criteria or objectives, which may conflict with each other. The MCDM method provides a systematic way to deal with such multi-criteria decision-making problems.

[0262] MCDM is an important part of modern decision science. Its theories and methods are widely used in engineering and can be used to judge the quality of multi-objective schemes, plans, and designs in production, economy, science, and engineering activities. MCDM can be divided into multi-attribute decision making and multi-objective decision making. Multiple attribute decision making (MADM, multiple attribute decisionmaking) means that there are limited alternatives to choose from; if the alternatives are infinite, it is multiple objective decision making (MODM, multiple objective decision making). Sometimes MADM is also called a multi-objective decision problem with a limited number of options, or a discrete target decision problem, or a comprehensive evaluation problem. Comprehensive evaluation of economic benefits, overall quality evaluation of talents, world university rankings, overall evaluation of technological progress levels, investment decisions, project evaluation, etc. all belong to this type of decision problems. The comprehensive evaluation index is the basis for making decisions, so calculating the comprehensive evaluation index is the core of MCDM, and the MCDM framework is suitable for calculating the comprehensive evaluation index. Reference for the process of calculating the comprehensive evaluation index under the MCDM framework Figure 5 shown.

[0263] The present invention quantifies the energy power indicator system based on the MCDM framework and calculates the energy power index. The entropy weight method is used in the weight calculation link, and the indicator weight is determined by using the concept of entropy. Specifically, the importance and information content of the indicator are determined according to the degree of difference in the indicator value. The greater the information content, the greater the indicator weight. This solves the actual weight problem when evaluating the energy power indicator system.

[0264] In some optional embodiments, the above step S31 can be implemented in the following manner:

[0265] The data of each third-level indicator of each country are used as elements in the matrix to construct a decision matrix. The rows of the decision matrix represent the country, and the columns represent the third-level indicators.

[0266] For example, taking countries as columns and indicators as rows, a decision matrix is ​​constructed based on the data of each third-level indicator of each country, as shown in the following matrix:

[0267]

[0268] In the above matrix (1), m represents the number of countries, n represents the number of third-level indicators, and X mnRepresents the data of the nth level 3 indicator in the mth country.

[0269] In some optional embodiments, the above step S32 can be implemented in the following manner:

[0270] (1) Determine the maximum and minimum values ​​of each third-level indicator;

[0271] (2) According to the maximum and minimum values ​​of each third-level indicator, the data of each third-level indicator corresponding to each country are normalized.

[0272] Evaluation indicators can be divided into positive indicators and negative indicators. Positive indicators refer to indicators whose larger values ​​are better, while negative indicators refer to indicators whose smaller values ​​are better.

[0273] The positive indicators for each country are normalized using the following formula:

[0274]

[0275] The positive indicators for each country are normalized using the following formula:

[0276]

[0277] In the above formulas (2) and (3), X mi and X max are the minimum and maximum values ​​of the original data of the same indicator, respectively, and X represents the data of the indicator in each country.

[0278] The decision matrix after normalization is shown as follows:

[0279]

[0280] In (4) above, x mn is X in formula (1) mn The normalized value.

[0281] In some optional embodiments, the entropy weight method can be used to determine the weight value of each third-level indicator. With the help of the principle of information entropy, the uncertainty and redundancy of the evaluation indicators are quantitatively analyzed, and then appropriate weights are assigned to each evaluation indicator. In this method, the differences between the indicators are fully reflected, ensuring that the distribution of weights is more scientific and reasonable. The wider the range of variation of an indicator, the richer the information it carries, and therefore, its weight is correspondingly higher. Specifically, the weight value of each third-level indicator is determined, and reference is made to Figure 4 As shown, this can be achieved, for example, by the following methods:

[0282] Step S41: Calculate the data in the decision matrix to determine the weight of the indicator value of each country corresponding to each third-level indicator;

[0283] For example, it can be calculated by the following formula:

[0284]

[0285] In the above formula (5), p ij represents the weight of the index value of the i-th country under the j-th index, x ij is the normalized value of the jth indicator in the ith country.

[0286] Step S42: determining the information entropy value of each third-level indicator according to the proportion of the indicator value of each country corresponding to each third-level indicator;

[0287] For example, it can be calculated by the following formula:

[0288]

[0289] In the above formula (6), Other parameters have been described above and will not be described in detail in this embodiment of the present invention.

[0290] It should be noted that if p ij = 0, then define

[0291] Step S43: Determine the weight value of each third-level indicator according to the information entropy value of each third-level indicator.

[0292] For example, it can be calculated by the following formula:

[0293]

[0294] In the above formula (7), w j Represents the weight value of indicator j. Other parameters have been described in the foregoing and will not be described in detail in this embodiment of the present invention.

[0295] In some optional embodiments, the above step S33 may be implemented, for example, in the following manner:

[0296] (1) For each country, the product of the normalized data of each level 3 indicator of the country and the weight value of the corresponding level 3 indicator is summed up;

[0297] For example, it can be calculated by the following formula:

[0298]

[0299] In the above formula 8, x jRepresents the data of the jth indicator after normalization.

[0300] (2) The sum of the results is used as the country’s energy power index.

[0301] Based on the above-mentioned energy power index determination method, the embodiment of the present invention also provides an energy power evaluation method, the process is as follows: Figure 6 As shown, the following steps are included

[0302] Step S61: determining the energy power index of each country, where the energy power index is determined by the aforementioned energy power index determination method;

[0303] Step S62: Sort the energy power index of each country according to its numerical value.

[0304] Based on the aforementioned method of constructing the energy power indicator system and determining the energy power index, the countries are ranked according to the numerical value of the energy power index. The ranking results have the function of promoting and guiding practice. They guide countries or economies to optimize their energy strategies and policies in an effort to become energy powers. This can not only help countries improve energy security, increase energy efficiency, and reduce environmental impact, but also enhance international influence and economic benefits.
