Description

TECHNICAL FIELD

[0001] The present application relates to the field of power system operation and power market stability, and particularly relates to a spot market stability regulation section checking method, system, device and medium. BACKGROUND

[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 modes, ensuring that the power system can still operate normally under complex and unexpected situations. However, as the scale of the power system continues to expand and equipment continues to be added and maintained, existing stability regulations often have redundancy, duplication and missing situations. These problems not only increase the complexity of power market management, but also may pose a hidden danger to the safety of the power grid.

[0003] Currently, the stability regulations of the spot market are usually directly issued by the system after calculation, and are manually reviewed and adjusted. However, since the system does not have the ability to automatically detect redundant, duplicate and missing regulations, the efficiency of manual review is low and errors are prone to occur, especially in complex situations such as equipment maintenance and new equipment commissioning. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application provides a spot market stability regulation section checking method, system, device and medium, which automatically compares, filters and optimizes stability regulation data to ensure that only valid stability regulations that meet the actual power grid operating state are retained in the system.

[0016] For the prompted missing provisions, the staff can supplement new provisions according to the actual situation of the power grid, ensuring the completeness and accuracy of the stable provisions.

[0017] Further, the method for comparing the formula structures in different stable provisions is:

[0018] Extracting the section composed of the equipment pointed by the formula structure of each stable provision;

[0019] If the sections corresponding to multiple stable provisions are the same, it is considered that the formula structures of the multiple stable provisions are the same, and the multiple stable provisions are marked as possible repeated stable provisions;

[0020] If the overlap rate of the equipment pointed by the sections corresponding to multiple stable provisions exceeds a set threshold, it is considered that the formula structures of the multiple stable provisions are similar, and the multiple stable provisions are marked as possible redundant stable provisions.

[0026] Further, step S4 specifically includes:

[0027] For each set of repeated stability regulations, the stability regulation with the time stamp closest to the actual operation state of the power grid is selected to be retained;

[0028] For each set of redundant stability regulations, the stability regulation with the highest transfer ratio or the smallest limit is selected to be retained by comparing the transfer ratio and the limit of each stability regulation in the set.

Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor.

[0041] Figure 1 is a flow chart of a spot market stability regulation section checking method provided by the embodiment of the present application;

[0042] Figure 2 is a structural schematic diagram of a spot market stability regulation section checking system provided by the embodiment of the present application. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0044] As shown in Figure 1 , the embodiment of the present application provides a spot market stability regulation section checking method, which includes the following steps:

[0045] S1: obtaining stability regulation data from the spot market system.

[0046] Stability regulation data is obtained from the spot market system regularly, including temporary regulations after equipment maintenance and new equipment commissioning. The obtained stability regulation data includes device ID, formula structure, transfer ratio, limit, time stamp and effective condition and other key information.

[0047] S2: Analyze the stable regulations, extract the key information in each stable regulation, including device ID, formula structure, transfer ratio, limit, timestamp, and effective condition, and store the extracted key information to provide a data basis for subsequent comparison and screening.

[0048] S3: Compare the formula structure and effective condition of different stable regulations, and screen out repeated or redundant stable regulations.

[0049] Among them, the method for comparing the formula structure of different stable regulations is:

[0050] Extract the cross section composed of the device pointed to by the formula structure of each stable regulation; for example, formula , x% is the transfer ratio, H is the limit, and devices A and B form a cross section;

[0051] If the cross sections corresponding to multiple stable regulations are the same, it is considered that the formula structures of the multiple stable regulations are the same, and the multiple stable regulations are marked as possible repeated stable regulations; for example, formula and formula A+B≤I, both formula structures point to the cross section composed of devices A and B, so it is considered that the formula structures are the same;

[0052] If the overlap rate of the devices pointed to by the cross sections corresponding to multiple stable regulations exceeds a set threshold (the set threshold is set according to the actual situation, such as 50%, 60%, or 70%, etc., and in this embodiment, 60% is taken as an example for illustration), it is considered that the formula structures of the multiple stable regulations are similar, and the multiple stable regulations are marked as possible redundant stable regulations; for example, formula and formula A+B+C≤J, the two formula structures point to the cross section composed of devices A and B and the cross 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%, so it is considered that the formula structures are similar.

[0053] After comparing the formula structures, it is also necessary to compare according to the effective condition, for example, one stable regulation may be effective during device maintenance, and another stable regulation may be effective only after the new device is put into operation, and it is necessary to match according to the effective condition to identify whether there are repeated or redundant stable regulations.

[0054] The specific method for screening out repeated or redundant stable regulations includes:

[0055] If the formula structure and effective condition of multiple stable regulations are the same, and the transfer ratio and limit are completely consistent, it is considered that the multiple stable regulations are a group of repeated stable regulations;

[0056] If the formula structure and effective condition of multiple stable regulations are the same, but the transfer ratio / limit is not consistent, it is considered that the multiple stable regulations are a group of redundant stable regulations;

[0057] If multiple stability provisions have similar formula structure and same effective condition, the multiple stability provisions are considered as a group of redundant stability provisions.

[0058] If multiple stability provisions have similar formula structure but different effective condition, the multiple stability provisions are considered as irrelevant.

[0059] S4: For repeated or redundant stability provisions, the stability provision that is more suitable for the current actual operation state of the power grid is selected for retention according to the transfer ratio, limit and time stamp, specifically including:

[0060] For each group of repeated stability provisions, the stability provision with the time stamp closest to the actual operation state of the power grid is selected for retention;

[0061] For each group of redundant stability provisions, the stability provision with the most stringent rule, i.e., the highest transfer ratio or the smallest limit, is selected for retention by comparing the transfer ratio and limit of each stability provision in the group, and the invalid or obsolete stability provision is deleted; for example, if the transfer ratio of device A is improved after N-1 (here N-1 refers to the case where device A sends a fault exit under the normal operation state of the power system), the invalid stability provision will be prompted and deleted.

[0062] Through optimization of the stability provisions, it is ensured that only valid provisions that meet the current state of the power grid are retained. The final generated list of stability provisions will remove redundant, repeated or inapplicable stability provisions.

[0063] S5: According to the current operation state of the power grid, equipment maintenance and line state, it is checked whether there is a missing stability provision, and if so, a missing item prompt is performed. For example, if there should be a stability provision effective during the maintenance of a certain device, but no corresponding stability provision is found in the system, a missing stability provision will be prompted. In specific implementation, when a missing stability provision is detected, the working staff will be prompted through the interface, for example: “XX device related stability provision is missing, please check the equipment maintenance plan and supplement the relevant provisions”.

[0064] S6: Manual confirmation is performed on repeated, redundant and missing stability provisions, specifically including:

[0065] The working staff checks all filtered stability provisions in the interface and confirms the stability provisions that need to be effective by checking; for repeated or redundant stability provisions, the working staff selects the stability provision that is more suitable for the current actual operation state of the power grid for retention, to ensure that the provision finally effective in the system is the most appropriate one;

[0066] For the prompted missing provisions, the working staff can supplement new provisions according to the actual situation of the power grid to ensure the completeness and accuracy of the stability provisions.

[0067] After steps S1 to S6, comprehensive, correct and unique stability regulations are obtained, based on which spot market clearing calculation is completed to obtain day-ahead or intraday output curves of various power sources (including one or more of thermal power, hydropower, wind power, photovoltaic power and the like) participating in the spot market, and then the corresponding power sources are dispatched and controlled according to the day-ahead or intraday output curves of the various power sources.

[0068] The spot market stability regulation section verification method provided by the above embodiment has the following beneficial effects:

[0069] (1) Automatic redundancy and repeated screening: the present application realizes automatic redundancy and repeated screening of stability regulations through intelligent comparison method, significantly improves the speed and accuracy of rule matching, and reduces the necessity of manual intervention;

[0070] (2) Accurate comparison of formula structure and effective condition: through comprehensive comparison of formula structure and effective condition, misjudgment caused by formula difference or different effective conditions is avoided, and only necessary regulations during power grid operation are ensured to be effective;

[0071] (3) Real-time missing regulation prompt: after screening is completed, the system can timely find and prompt missing stability regulations, help staff quickly supplement relevant items, and ensure completeness of the regulations;

[0072] (4) Manual confirmation and optimization mechanism: even if the result after automatic screening, manual confirmation link is still reserved, to ensure that the finally effective regulations completely meet the power grid operation state, and avoid incorrect judgment.

[0073] (5) By screening repeated, redundant and missing stability regulations from the current effective stability regulation set, the accuracy of spot market clearing calculation is ensured, thereby avoiding problems such as new energy curtailment or settlement abnormality caused by partial section overload of power grid during actual operation of the power grid due to inaccurate spot market clearing calculation.

[0074] In summary, the spot market stability regulation section verification method provided by the above embodiment effectively solves the problems of redundancy, repetition and missing of power grid stability regulations, can effectively improve the precision and efficiency of power grid management, reduce human intervention, and ensure safe and stable operation of the power grid.
