Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle - grid interaction, and in particular, to a method for constructing a vehicle - grid interaction standard system. Background Technique

[0002] A standard system is a scientific organic whole formed by the internal connection of standards within a certain range. Constructing a standard system is a method of guiding standardization work using systems theory, and it is the basis and prerequisite for carrying out standard system construction, as well as the basis for compiling standards, revising plans and programs.

[0003] Vehicle - grid interaction technology and its application data are an important part of the country's strategic emerging industries, representing the development direction of the deep integration of future intelligent transportation and the energy Internet. Among them, constructing a complete vehicle - grid interaction standard system to achieve standardized operation is precisely the core foundation for promoting the progress of vehicle - grid interaction technology, facilitating its wide application, and optimizing industrial chain coordination. The establishment of this standard system aims to standardize various aspects such as information exchange, energy flow, and safety management between vehicles and the power grid, thereby improving resource utilization efficiency, ensuring the stable and reliable operation of the system, and strongly driving the coordinated development of the new energy vehicle industry and the modern power system.

[0004] Currently, the standard status in the field of vehicle - grid interaction shows a certain degree of complexity and repetition, and a systematic standard system has not been formed. The insufficient standardization has become a significant bottleneck restricting the further development of this field. Due to the lack of unified and clear standard specifications, inconsistencies and chaos have occurred in multiple links such as the research and development of key vehicle - grid interaction technologies, product design, market promotion, and service operation, thereby affecting the efficiency and safety of the interaction between electric vehicles and the power grid, delaying the pace of new infrastructure construction, and limiting the full development potential of the energy Internet.

[0044] The following further details the embodiments of the present invention with reference to the accompanying drawings:

[0045] A method for constructing a vehicle-grid interaction standard system, as Figure 1 shown, includes the following steps:

[0046] Step 1: Construct a standard six-dimensional structure system for vehicle-grid interaction;

[0047] As Figure 2 shown, the standard six-dimensional structure system of vehicle-grid interaction in Step 1 includes: nature dimension, professional dimension, time dimension, attribute dimension, level dimension, and state dimension.

[0048] In this embodiment, Step 1 draws on the Hall three-dimensional structure theory, which generally includes the time dimension (reflecting the evolution process and timeliness of standards), the logical dimension (reflecting the internal connections and hierarchical relationships between standards), and the knowledge dimension (covering professional knowledge in various related technical, management, and service fields). On this basis, the present invention further expands this theoretical framework. In response to the needs of the specific field of vehicle-grid interaction, three dimensions are creatively added and the three-dimensional structure is refined to form a multi-dimensional and multi-level six-dimensional structure system of nature dimension, professional dimension, time dimension, attribute dimension, level dimension, and state dimension applicable to the vehicle-grid interaction standard system.

[0049] (1) Construction of a six-dimensional structure system. The Hall three-dimensional structure, also known as Hall's systems engineering, is a systems engineering methodology proposed by American systems engineering experts such as Hall based on a large number of engineering practices. The Hall three-dimensional structure forms a three-dimensional space structure composed of the time dimension, the logical dimension, and the knowledge dimension. Drawing on the Hall three-dimensional structure theory, on this basis, the present invention further expands this theoretical framework. In response to the needs of the specific field of vehicle-grid interaction, three dimensions are creatively added and the three-dimensional structure is refined, forming a multi-dimensional and multi-level six-dimensional structure system of the nature dimension, the professional dimension, the time dimension, the attribute dimension, the level dimension, and the state dimension applicable to the vehicle-grid interaction standard system.

[0050] Based on the basic theoretical structure of the Hall three-dimensional structure: the time dimension, the logical dimension, and the knowledge dimension, the present invention constructs a multi-dimensional and multi-level six-dimensional structure system applicable to the vehicle-grid interaction standard system. As Figure 2 shown, the present invention constructs a six-dimensional structure of the nature dimension, the professional dimension, the time dimension, the attribute dimension, the level dimension, and the state dimension, initially locates the storage location of the vehicle-grid interaction standard in the standard system database, and stores it using the six-dimensional data label of (nature dimension A, professional dimension S, time dimension D, attribute dimension F, level dimension G, state dimension H).

[0051] Step 2. Expand the indicators of the six-dimensional structure system of the vehicle-grid interaction standard constructed in Step 1 to form the vehicle-grid interaction standard system indicators;

[0052] The vehicle-grid interaction standard system indicators constructed in Step 1 include:

[0053] (1) The nature dimension is divided into technical standard 01, economic standard 02, and management standard 03.

[0054] (2) The professional dimension is divided into network interaction principle 01, vehicle networking technology 02, and network security technology 03;

[0055] (3) The time dimension is divided into demonstration 01, design 02, test 03, acceptance 04, evaluation 05, use and maintenance 06, and scrapping 07;

[0056] (4) The attribute dimension is divided into basic standard 01, information security standard 02, construction and operation standard 03, detection and evaluation standard 04, service network standard 05, and power supply standard 06;

[0057] (5) The level dimension is divided into international standard 01, national standard 02, industry standard 03, local standard 04, and group standard 05;

[0058] (6) The state dimension is divided into being drafted 01, being solicited for comments 02, being reviewed 03, being approved 04, having been released 05, and having been terminated 06.

[0059] In this embodiment, the vehicle-grid interaction indicator system constructed based on step 1 is expanded in detail, and is expanded step by step from the nature dimension, professional dimension, time dimension, attribute dimension, level dimension, and status dimension to form the overall structure of the standard system.

[0060] Among them, the nature dimension is divided into technical standards 01, economic standards 02, and management standards 03; the professional dimension is divided into network interaction principles 01, Internet of Vehicles technology 02, and network security technology 03; the time dimension is divided into demonstration 01, design 02, test 03, acceptance 04, evaluation 05, use and maintenance 06, and scrapping 07; the attribute dimension is divided into basic standards 01, information security standards 02, construction and operation standards 03, testing and evaluation standards 04, service network standards 05, and power supply standards 06; the level dimension is divided into international standards 01, national standards 02, industry standards 03, local standards 04, and group standards 05; the status dimension is divided into under drafting 01, soliciting opinions 02, under review 03, under approval 04, published 05, and terminated 06, forming the overall structure of the standard system.

[0061] Step 3: Perform standard retrieval and data cleaning on the indicator data in the vehicle-network interaction standard system in step 2;

[0062] The specific steps of step 3 include:

[0063] (1) Based on the six-dimensional structure system of vehicle-grid interaction standards constructed in step 1, determine the six-dimensional architecture keyword set for standard search, search for relevant standard documents, and assign a unified six-dimensional number to the retrieved standard documents for identification and management;

[0064] (2) Based on the six-dimensional architecture keywords determined in step 3 (1), the collected standard documents are cleaned. After the Web Scraper crawls the files, the artificial intelligence Octopus is used to recognize the text and eliminate irrelevant or redundant data information.

[0065] In this embodiment, these keywords are used to conduct extensive and in-depth searches in multiple information channels such as authoritative standard publishing websites at home and abroad, professional literature databases, etc., to obtain relevant standard document materials.

[0066] For the retrieved standard documents, a unified six-dimensional number is given for identification and management. Then, according to the six-dimensional architecture keywords determined in step 3 (1), the collected standard documents are cleaned. After the Web Scraper grabs the files, the artificial intelligence Octopus is used to recognize the text, including removing special characters, extracting relevant core content according to the keyword set, identifying standard codes, etc., eliminating irrelevant or redundant data information, and retaining only the data content that is directly related to the vehicle-network interaction and valid.

[0067] Step 4: Assign weights and combine the indicators of the vehicle-grid interaction standard six-dimensional structure system after cleaning in Step 3;

[0068] The specific method for Step 4 is as follows:

[0069] Use the CRITIC method to assign weights to the constructed vehicle-grid interaction standard six-dimensional structure system indicators to obtain the weight vector group Q1, and select the top a% of the indicators in each dimension as the indicator system.

[0070] In this embodiment, the CRITIC method is an objective weighting method that is better than the entropy weight method and the standard deviation method. It comprehensively measures the objective weights of indicators based on the comparison intensity of evaluation indicators and the conflict between indicators. While considering the size of indicator variability, it also takes into account the correlation between indicators. It does not mean that the larger the number, the more important it is. It fully utilizes the objective attributes of the data itself for scientific evaluation. The comparison intensity refers to the size of the value gap between different evaluation schemes of the same indicator, which is expressed in the form of the standard deviation. The larger the standard deviation, the greater the fluctuation, that is, the greater the value gap between the schemes, and the higher the weight. The conflict between indicators is represented by the correlation coefficient. If there is a strong positive correlation between two indicators, it means that their conflict is smaller and the weight will be lower.

[0071] For the CRITIC method, when the standard deviation is fixed, the smaller the conflict between indicators, the smaller the weight; the greater the conflict, the greater the weight. In addition, when the positive correlation degree between two indicators is greater (the correlation coefficient is closer to 1), the conflict is smaller, which indicates that the information reflected by these two indicators in evaluating the quality of the evaluation scheme has a greater similarity. The steps are as follows:

[0072] Form the original indicator data matrix X:

[0073]

[0074] where X np represents the value of the pth evaluation indicator of the nth sample.

[0075] Positive normalization:

[0076]

[0077] Calculate the standard deviation:

[0078]

[0079] where S p represents the standard deviation of the pth indicator.

[0080] In the CRITIC method, the standard deviation is used to represent the difference and fluctuation of the values within each indicator. The larger the standard deviation, the greater the numerical difference of the indicator, the more information it can reflect, and the stronger the evaluation intensity of the indicator itself. More weight should be assigned to this indicator.

[0081] Calculate the correlation coefficient:

[0082]

[0083] Among them, r np represents the correlation coefficient between evaluation indicators n and p.

[0084] Calculate the amount of information C p :

[0085]

[0086] C p The larger C is, the greater the role of the p-th evaluation indicator in the entire evaluation indicator system, and more weight should be assigned to it.

[0087] Calculate the objective weight:

[0088]

[0089] Among them, W p is the objective weight of the p-th indicator.

[0090] Step 5: Examine the six-dimensional structure system indicators of the vehicle-network interaction standard in Step 4 to form the final evaluation indicator system;

[0091] The specific method of Step 5 is as follows:

[0092] Based on the indicator system described in Step 4, use a word frequency analysis tool to study and analyze the frequency of each indicator text appearing in the test sample, and eliminate the indicators with a word frequency of 0 to form the final evaluation indicator system.

[0093] Step 6: Real-time update and standardized output.

[0094] The specific method of Step 6 is as follows:

[0095] The constructed database system uses Web Scraper to crawl the latest released vehicle-network interaction related standard information on the Internet once a month, automatically updates the standard system, and ensures that the standards in the database always keep in sync with the development of the vehicle-network interaction industry.

[0096] In addition, the database exports the stored standard data specifications through internal six-dimensional coding to achieve data standardization, enabling both researchers and industry practitioners to conveniently and quickly obtain the integrated and processed vehicle-grid interaction standard data that conforms to the national standard system structure, which strongly promotes the R & D, application, and industrialization process of vehicle-grid interaction technology.

[0097] Finally, the database regularly crawls network data and updates the standards, and can export the standardized standard data.

[0098] A device for constructing a vehicle-grid interaction standard system proposed by the present invention is used to cooperate with the system construction method. As Figure 3 shown, it includes a central processing unit 301, input and output devices 302 (such as a display screen, mouse, keyboard, etc.), a ROM 303, and a RAM 304 memory. Among them, the central processing unit is responsible for data cleaning, data encoding, etc.; the input and output devices are responsible for outputting data to or from the database. The RAM, that is, the random access memory, is responsible for temporarily storing data when the central processing unit processes data; the ROM, that is, the read-only memory, is responsible for long-term storage of the data processed by the central processing unit.

[0099] The working principle of the present invention is:

[0100] Starting from the top-level planning, the present invention comprehensively sorts out and integrates various existing vehicle-grid interaction standards, constructs a sound, coordinated, and open standard system covering key interfaces, data exchange, information security, and test evaluation, and promotes the vehicle-grid interaction industry to move forward to a higher level and deeper level with the power of standardization.

Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manners. Any other implementation manners obtained by those skilled in the art based on the technical solutions of the present invention also belong to the scope protected by the present invention.
