Description

Technical Field

[0001] The present invention relates to the field of power system operation and power market stability, and in particular to a method, system, equipment and medium for checking a specified section of a spot market stability. Background Art

[0002] In the power market, stability regulations are used to ensure the safe and stable operation of the power grid. These regulations usually include specific requirements for different equipment, lines, and power grid operation methods to ensure that the power system can still operate normally under complex and unexpected circumstances. However, with the continuous expansion of the power system scale and the continuous addition and maintenance of equipment, the existing stability regulations often become redundant, repeated, and missing. These problems not only increase the complexity of power market management, but may also pose a hidden danger to the safety of the power grid.

[0003] At present, the stability regulations of the spot market are usually issued directly after calculation by the system and are manually reviewed and adjusted. However, since the system does not have the ability to automatically detect redundant, repeated and missing regulations, manual review is inefficient and prone to errors. This problem is particularly prominent in complex situations such as equipment maintenance and the commissioning of new equipment. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method, system, equipment and medium for verifying the stability regulations section of the spot market, which ensures that only effective stability regulations that meet the actual power grid operation status are retained in the system by automatically comparing, screening and optimizing the stability regulations data.

[0005] In a first aspect, a method for verifying a spot market stability regulation section is provided, comprising the following steps: S1: Obtain stable regulation data from the spot market system; S2: Parse the stability regulation data and extract key information from each stability regulation, including device ID, formula structure, transfer ratio, limit, timestamp, and effective conditions; S3: Compare the formula structures and effective conditions in different stability regulations and filter out duplicate or redundant stability regulations; S4: For repeated or redundant stability regulations, the stability regulations that are more in line with the actual operating status of the current power grid are selected based on the transfer ratio, limit and timestamp.

[0006] Furthermore, it also includes: According to the current grid operation status, equipment maintenance, and line status, check whether there are any missing stability regulations. If so, prompt for missing items.

[0007] Furthermore, it also includes: Manual confirmation of duplicate, redundant, and missing stable provisions.

[0008] Furthermore, manual confirmation of duplicate, redundant and missing stable provisions specifically includes: The staff will check all the selected stability regulations in the interface and confirm the stability regulations that need to be effective by checking them. For duplicate or redundant stability regulations, the staff will choose to retain the stability regulations that are more in line with the actual operation status of the current power grid to ensure that the regulations that finally take effect in the system are the most appropriate. For missing regulations pointed out, staff can add new regulations based on the actual situation of the power grid to ensure the completeness and accuracy of the stability regulations.

[0009] Further, the formula structure methods in different stability regulations are compared as follows: Extract the cross section of the equipment components pointed to by each stable prescribed formula structure; If the sections corresponding to multiple stability regulations are the same, then the formula structures of the multiple stability regulations are considered to be the same, and the multiple stability regulations are marked as possible repeated stability regulations; If the equipment overlap rate of the sections corresponding to multiple stability regulations exceeds a set threshold, it is considered that the formula structures of the multiple stability regulations are similar, and the multiple stability regulations are marked as possible redundant stability regulations.

[0010] Furthermore, step S3 specifically includes: If multiple stabilization provisions have the same formula structure and entry into force conditions, and the same transfer ratios and limits, then the multiple stabilization provisions are considered to be a set of duplicate stabilization provisions; If multiple stabilization provisions have the same formula structure and entry into force conditions, but different transfer ratios / limits, the multiple stabilization provisions are considered to be a set of redundant stabilization provisions; If the formula structures of multiple stability provisions are similar and their effectiveness conditions are the same, then the multiple stability provisions are considered to be a set of redundant stability provisions; If multiple stability provisions have similar formula structures but different entry into force conditions, the multiple stability provisions are considered unrelated.

[0011] Furthermore, step S4 specifically includes: For each set of repeated stability regulations, the stability regulation with the retention time closest to the actual operation state of the power grid is selected through the timestamp; For each set of redundant stable regulations, compare the transfer ratio and limit of each stable regulation, and choose to retain the stable regulation with the highest transfer ratio or the smallest limit.

[0012] Second, a spot market stability regulation section verification system is provided, including: The stable regulation data receiving module is used to obtain the stable regulation data from the spot market system, parse the stable regulation data, and extract the key information of each stable regulation, including the device ID, formula structure, transfer ratio, limit, timestamp and effective condition; The formula structure and effective condition comparison module is used to compare the formula structure and effective conditions in different stability regulations and filter out duplicate or redundant stability regulations; Redundant and duplicate regulations screening module, used for selecting and retaining the duplicate or redundant stability regulations that are more in line with the actual operation status of the current power grid according to the transfer ratio, limit and timestamp; The missing provision prompt module is used to check whether there are missing stability provisions according to the current power grid operation status, equipment maintenance, and line status. If so, it will prompt the missing items; The manual confirmation and optimization module is used to manually confirm repeated, redundant and missing stable regulations.

[0013] In a third aspect, an electronic device is provided, including: Memory on which computer programs or instructions are stored; A processor is used to load and execute the computer program or instructions to implement the spot market stability regulation section verification method as described above.

[0014] In a fourth aspect, a computer-readable storage medium is provided, on which a computer program or instruction is stored, and when the computer program or instruction is executed by a processor, the method for verifying the section of the spot market stability regulations as described above is implemented.

[0015] The present invention proposes a method, system, device and medium for checking the stability regulations section of the spot market. By comparing the formula structure and effectiveness conditions of the stability regulations data transmitted from the spot system, repeated and redundant stability regulations are screened out, and then the stability regulations are optimized to ensure that only effective stability regulations that meet the actual power grid operation status are retained in the system, and redundant and repeated stability regulations are eliminated; in addition, real-time prompts can be provided for missing regulations. The present invention effectively solves the problems of redundancy, duplication and missing of power grid stability regulations, can effectively improve the accuracy and efficiency of power grid management, reduce human intervention, and ensure the safe and stable operation of the power grid.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0017] Figure 1 It is a flow chart of a method for checking a stable regulation section of a spot market provided by an embodiment of the present invention; Figure 2 It is a schematic diagram of the structure of a spot market stability regulation section verification system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0018] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0019] like Figure 1 As shown, the embodiment of the present invention provides a method for checking the stability regulation section of the spot market, comprising the following steps: S1: Obtain stability regulation data from the spot market system.

[0020] Regularly obtain stable regulation data from the spot market system, including temporary regulations after equipment maintenance and new equipment commissioning, etc. The stable regulation data obtained includes key information such as equipment ID, formula structure, transfer ratio, limit, timestamp and effective conditions.

[0021] S2: Parse the stability regulation data and extract the key information in each stability regulation, including device ID, formula structure, transfer ratio, limit, timestamp and effective conditions. Store the extracted key information to provide a data basis for subsequent comparison and screening.

[0022] S3: Compare the formula structures and effectiveness conditions in different stability regulations and filter out duplicate or redundant stability regulations.

[0023] Among them, the formula structure method for comparing different stability regulations is: Extract the cross section of the equipment structure pointed to by each stable formula structure; such as formula , x% is the transfer ratio, H is the limit, equipment A and equipment B form the section; If the sections corresponding to multiple stability regulations are the same, then the formula structures of the multiple stability regulations are considered to be the same, and the multiple stability regulations are marked as possible repeated stability regulations; for example, And the formula A+B≤I, both formula structures point to the section composed of equipment A and equipment B, so the formula structures are considered to be the same; If the equipment overlap rate of the cross-sections corresponding to the multiple stability regulations exceeds a set threshold (the set threshold is set according to the actual situation, such as 50%, 60% or 70%, etc., and 60% is used as an example in this embodiment), it is considered that the formula structures of the multiple stability regulations are similar, and the multiple stability regulations are marked as possible redundant stability regulations; if the formula And the formula A+B+C≤J, the two formula structures point to the section composed of devices A and B and the section composed of devices A, B, and C respectively. At this time, the overlap rate is 66.6%, which is greater than the set threshold of 60%, and the formula structures are considered to be similar.

[0024] After comparing the formula structures, they also need to be compared based on the effective conditions. For example, a certain stability provision may be effective during equipment maintenance, while another stability provision may only be effective after the new equipment is put into production. It is necessary to match them based on the effective conditions to identify whether there are repeated or redundant stability provisions.

[0025] Specific methods for screening out duplicate or redundant stabilization provisions include: If multiple stabilization provisions have the same formula structure and entry into force conditions, and the same transfer ratios and limits, then the multiple stabilization provisions are considered to be a set of duplicate stabilization provisions; If multiple stabilization provisions have the same formula structure and entry into force conditions, but different transfer ratios / limits, the multiple stabilization provisions are considered to be a set of redundant stabilization provisions; If the formula structures of multiple stability provisions are similar and their effectiveness conditions are the same, then the multiple stability provisions are considered to be a set of redundant stability provisions; If multiple stability provisions have similar formula structures but different entry into force conditions, the multiple stability provisions are considered unrelated.

[0026] S4: For repeated or redundant stability regulations, select and retain the stability regulations that are more in line with the actual operation status of the current power grid according to the transfer ratio, limit and timestamp, including: For each set of repeated stability regulations, the stability regulation with the retention time closest to the actual operation state of the power grid is selected through the timestamp; For each set of redundant stability regulations, compare the transfer ratio and limit of each stability regulation, select the most stringent rule, that is, the stability regulation with the highest transfer ratio or the smallest limit, and delete the invalid or outdated stability regulations; for example, after N-1 (here N-1 refers to the situation where the power system is operating normally and device A sends a fault exit) the transfer ratio increases, the invalid stability regulation will be prompted and deleted.

[0027] By optimizing the stability regulations, only valid regulations that meet the current grid status are retained. The final stability regulations list will remove redundant, repeated or inapplicable stability regulations.

[0028] S5: Check whether there are any missing stability regulations based on the current grid operation status, equipment maintenance, and line status. If so, prompt for missing items. For example, if a stability regulation should be in effect during the maintenance of a certain equipment, but the corresponding stability regulation is not found in the system, a prompt will be given that the stability regulation is missing. In specific implementation, when a missing stability regulation is detected, a prompt will be given to the staff through the interface, for example: "The relevant stability regulations of XX equipment are missing. Please check the equipment maintenance plan and supplement the relevant regulations."

[0029] S6: Manual confirmation of duplicate, redundant and missing stable provisions, including: The staff will check all the selected stability regulations in the interface and confirm the stability regulations that need to be effective by checking them. For duplicate or redundant stability regulations, the staff will choose to retain the stability regulations that are more in line with the actual operation status of the current power grid to ensure that the regulations that finally take effect in the system are the most appropriate. For missing regulations pointed out, staff can add new regulations based on the actual situation of the power grid to ensure the completeness and accuracy of the stability regulations.

[0030] After steps S1 to S6, a comprehensive, correct and unique stability regulation is obtained. Based on these stability regulations, the spot market clearing calculation is completed, and the day-ahead or intraday output curves of various power sources participating in the spot market (including one or more types of thermal power, hydropower, wind power, photovoltaic power generation, etc.) are obtained, and then the output dispatch control of the corresponding power source is carried out according to the day-ahead or intraday output curves of various power sources.

[0031] The above embodiment provides a method for checking the stability of the spot market, which has the following beneficial effects: (1) Automated redundancy and duplication screening: The present invention realizes automated redundancy and duplication screening of stable regulations through intelligent comparison methods, significantly improving the speed and accuracy of rule matching and reducing the necessity of manual intervention; (2) Accurate comparison of formula structure and effective conditions: By comprehensively comparing the formula structure with the effective conditions, misjudgment caused by differences in formulas or effective conditions is avoided, ensuring that only necessary regulations are effective during grid operation. (3) Real-time reminder of missing regulations: After the screening is completed, the system can promptly discover and remind missing stable regulations, helping staff to quickly supplement relevant items to ensure the completeness of the regulations; (4) Manual confirmation and optimization mechanism: Even after automatic screening, the manual confirmation process is still retained to ensure that the final effective regulations are fully in line with the operating status of the power grid and avoid misjudgment.

[0032] (5) By screening the set of stability regulations currently in effect for duplicate, redundant, and missing stability regulations, the accuracy of the spot market clearing calculation is ensured, thereby avoiding problems such as new energy power abandonment or settlement abnormalities caused by heavy overload of some sections of the power grid due to inaccurate spot clearing calculations during the actual operation of the power grid.

[0033] In summary, the spot market stability regulation section verification method provided by the above embodiment effectively solves the problems of redundancy, duplication and missing of power grid stability regulations, can effectively improve the accuracy and efficiency of power grid management, reduce human intervention, and ensure the safe and stable operation of the power grid.

If so, it will prompt the missing items; The manual confirmation and optimization module is used to manually confirm repeated, redundant and missing stable regulations.
