Description

Technical Field

[0001] The present invention belongs to the field of power system dispatching automation, and in particular relates to a method and system for adjusting a daily tie line plan in a large-scale bilateral transaction environment. Background Art

[0002] The scale of grid connection of new energy units will become larger and larger, which will put forward higher requirements on the level of power grid consumption of new energy power generation. At present, State Grid Corporation of China promotes the effective consumption of new energy and the mutual assistance of power supply surplus and shortage by organizing various market-based transactions such as cross-regional and cross-provincial spot transactions, peak-shaving auxiliary service transactions, inter-provincial spot transactions, and emergency power support transactions. The market-based transaction volume has doubled, and rigid execution is required. The execution of various spot transactions within the day must be updated to the interconnection line plan in a timely manner.

[0003] Therefore, the modification process of the intraday tie line plan is becoming more and more complicated. The buying and selling behaviors of market entities are often exchanged in multiple transactions in a day. The modification business of the tie line plan is increasingly showing the characteristics of "high complexity, high frequency, and large scale". The current way of manually modifying the tie line plan power value by the dispatching operation duty personnel can no longer adapt to the current situation of large-scale bilateral trading environment, where market-based transactions have increased exponentially and need to be rigidly executed. The existing tie line plan management software mainly executes the above-mentioned bilateral market transactions by manually modifying the tie line plan by the dispatcher. At present, under the background of the exponential growth of the scale of intraday bilateral market-based transactions, a bilateral market transaction often contains multiple transaction component modifications, or contains multiple types of power transmission such as inter-provincial transactions, cross-regional transactions, and cross-regional transfer transactions. The dispatcher needs to find the tie line through which the transaction power transmission path passes for each transaction one by one based on work experience, and modify the tie line plan value point by point according to the bilateral transaction volume. A lot of repetitive work needs to be completed every day, and it is difficult to complete the relevant tie line plan modification in time when bilateral market transactions are concentrated. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for adjusting the intraday tie line plan in a large-scale bilateral trading environment, so as to solve the problem in the prior art that the current tie line plan is manually modified by the dispatching operation duty personnel, and it is difficult to complete the relevant tie line plan modification in time.

[0009] Further, the names of the transaction components of the bilateral market transaction are obtained; wherein the names of the transaction components are constructed as follows: Determine the bilateral transaction type, seller's province, buyer's province and the DC system for bilateral market transactions; The transaction component name is determined according to the preset transaction component name format, as well as the bilateral transaction type, the seller's province, the buyer's province and the DC system passed through; wherein the transaction component name format is expressed as: bilateral transaction type-the seller's province (through a certain province) to the buyer's province+the DC system passed through 1+...+the DC system passed through n.

[0010] Furthermore, transaction types include inter-provincial spot market transactions, North China peak-shaving market transactions, cross-regional spot market transactions and cross-regional transfer market transactions.

[0011] Furthermore, the correlation coefficients of the interconnection lines through which the bilateral market exchanges pass and the bilateral market transactions corresponding to the interconnection lines are determined; when the positive direction definition of the interconnection line plan is consistent with the power transmission direction of the bilateral market transactions, the correlation coefficient of the interconnection line is 1, and when it is inconsistent, the correlation coefficient is -1.

[0013] According to a third aspect of the present invention, there is provided an electronic device comprising a processor and a memory, wherein the processor is configured to execute a computer program stored in the memory to implement the above-mentioned method for adjusting the intraday contact line plan in a large-scale bilateral trading environment.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0028] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0029] Example 1 The provinces in North China maintain the balance of power supply and demand in the power grid through bilateral market transactions such as inter-provincial spot market transactions in North China, North China peak load auxiliary service market transactions, cross-regional spot market transactions, cross-regional transfer spot transactions, and emergency power support. The features are as follows: ① Inter-provincial spot market transactions in North China are the main means of making up for the system load power shortage, and transactions are given priority and rigidly implemented within the North China control area; ② The North China Peak Loading Auxiliary Service Market Transactions: Generally, when the actual load is lower than the forecast value, when the unit output needs to be adjusted in depth, it can be adjusted through the Peak Loading Auxiliary Service Transactions; ③ When the power generation resources of the North China Power Grid are tight, cross-regional spot market transactions can be used to purchase electricity from outside the control area to alleviate the power shortage in the North China Power Grid; ④ Inter-regional spot transfer transactions are transactions between power grid regions adjacent to the North China Power Grid through the spot market. When executing transactions, power must be transferred through the borders of the North China Power Grid and the interconnection lines within the region. ⑤ Emergency power support is a planned adjustment operation in which the dispatcher urgently adjusts the output of the units in the area to ensure the balance of power supply and demand in the power grid when there is a failure in the transmission equipment of the North China Power Grid or the unit is shut down for maintenance.

[0030] This scheme proposes a method for adjusting the intraday tie line plan in a large-scale bilateral trading environment. It establishes an association dictionary table of typical transaction component names in the bilateral market and tie lines along the transmission path. It uses various bilateral transaction component names to perform fuzzy search in the association dictionary table to match all possible transmission paths for the transaction. It realizes the automatic adjustment of the tie line plan along the bilateral market transaction path. The supported bilateral transaction types include: inter-provincial spot market transactions in North China, peak-shaving market transactions in North China, cross-regional spot market transactions, and cross-regional transfer market transactions. For bilateral transactions that can match a unique transmission path, the tie line plan adjustment amount on the transaction transmission path can be automatically calculated. For bilateral transactions that match multiple transmission paths, the dispatcher manually determines the transmission ratio coefficients of multiple transmission paths and distributes the transaction volume in proportion. The tie line plan modification record of each bilateral transaction is saved, and the completion status of bilateral transactions is counted daily for the settlement of bilateral transactions at the end of the month.

[0031] The auxiliary dispatcher updates the intraday contact line plan in a timely, accurate and rapid manner for the results of a large number of bilateral market transactions completed during the day.

[0032] like Figure 1 As shown in the figure, a method for adjusting the intraday contact line plan in a large-scale bilateral trading environment includes: S1. Determine the names of the transaction components of each bilateral market transaction.

[0033] In step S1, the transaction component name is constructed as follows: Determine the bilateral transaction type, seller's province, buyer's province and DC system of bilateral market transactions; determine the transaction component name according to the preset transaction component name format, as well as the bilateral transaction type, seller's province, buyer's province and DC system; wherein the transaction component name format is expressed as: bilateral transaction type-seller's province (through a certain province) to buyer's province+DC system 1+...+DC system n. Among them, the transaction types include inter-provincial spot market transactions, North China peak load market transactions, inter-regional spot market transactions and inter-regional transfer market transactions.

[0034] Specifically, the name of the bilateral market transaction component is composed of the transaction type, seller's province, buyer's province, and the DC system of the channel. The name of the bilateral market transaction component is defined as follows: Bilateral transaction type - from the seller's province (through a certain province) to the buyer's province + via DC system 1 + ... + via DC system n For example: inter-provincial transactions - Province A sends to Province B, peak-shaving transactions - Province B sends to Province D, cross-regional transactions - Province A sends to Province F + DC system FB, cross-regional transfer - Province F sends to Province G + DC system FB + DC system DG.

[0035] More specific: 1) The name of the transaction component of the inter-provincial spot market is generally composed of the seller's province and the buyer's province. In the case where there are multiple power transmission routes from the seller's province to the buyer's province, it is necessary to add the description "through a certain province" to the transaction component name to clarify the provinces passed through.

[0036] For example, inter-provincial transactions - province A sends to province B, inter-provincial transactions - province A sends to province D via province B.

[0037] 2) The names of the transaction components of the North China peak-shaving market are generally composed of the seller's province and the buyer's province. In the case where there are multiple power transmission routes from the seller's province to the buyer's province, it is necessary to add the description "through a certain province" to the name of the transaction component to clarify the provinces passed through.

[0038] For example, peak-shaving transaction - province A sends to province B, peak-shaving transaction - province A sends to province D via province B.

[0039] 3) The names of cross-regional spot market transaction components are generally composed of the seller’s province (or buyer’s province) outside the North China region and the buyer’s province (or seller’s province) within the North China region. For the DC transmission lines that the power transmission path passes through, it is necessary to add “+DC system N” after the buyer’s province to clarify the name of the DC system that the power transmission path passes through. However, the specific provinces that pass through the North China region are generally not clearly marked in the transaction component names. The traditional method requires the dispatcher to determine based on work experience. The present invention establishes a dictionary table that associates the names of cross-regional spot market transactions with the interconnection lines that the power transmission path passes through, so that it is clear that the power transmission path of cross-regional spot transactions may pass through multiple interconnection lines in the North China region.

[0040] For example, cross-regional transactions - Province B sends to Province F + DC system FB, cross-regional transactions - Province A sends to Province E + DC system CE, cross-regional transactions - Province E sends to Province A + DC system CE 4) The names of the transaction components of the inter-regional transfer market are generally composed of the seller's province and the buyer's province outside the North China region. For the inter-provincial DC transmission lines that pass through, the description "+DC system 1+...+DC system N" needs to be added after the buyer's province to clarify the name of the DC system passed through in the transmission path. However, the specific provinces passed through in the North China region are generally not clearly marked in the transaction component name, and the transmission path of the inter-regional transfer market transaction may pass through multiple interconnection lines in the North China region.

[0041] like Figure 3 As shown in the figure, the bilateral transaction from Province F to Province H is: inter-regional transfer - Province F to Province H + DC system FB + DC system CE + DC system EH. There are two transmission paths through the North China Power Grid: Power transmission path ①: Province F → → → → → → Province H Power transmission path ②: Province F → → → → → → Province H like Figure 3 As shown in the figure, the bilateral transaction from Province F to Province H is: inter-regional transfer - Province F to Province H + DC system FB + DC system DG + DC system GH. There are also two transmission paths through the North China Power Grid: Power transmission path ③: Province F → → → → → Province H Power transmission path ④: Province F → → → → → → Province H like Figure 3 As shown, inter-regional transfer - Province F sends power to Province H + DC system FB + DC system CE + DC system EH, inter-regional transfer - Province F sends power to Province H + DC system FB + DC system DG + DC system GH.

[0042] S2. Identify keywords from the names of each of the transaction components; perform fuzzy matching of names in a preset transaction component name-connection line association dictionary table based on each of the keywords to find the power transmission paths corresponding to each of the bilateral market transactions; determine the connection lines passed by each of the bilateral market exchanges and the correlation coefficients of the bilateral market transactions corresponding to each of the connection lines based on the power transmission paths corresponding to each of the bilateral market transactions; wherein each of the bilateral market transactions corresponds to at least one power transmission path, and each of the power transmission paths is formed by a corresponding connection line.

[0043] In step S2, when the positive direction definition of the tie line plan of the tie line is consistent with the power transmission direction of the bilateral market transaction, the correlation coefficient of the tie line is 1, and when it is inconsistent, the correlation coefficient is -1.

[0044] The applicant needs to explain that the buyer and seller of bilateral market transactions need to complete the power transaction through the power transmission path. The transaction power transmission path is formed by the interconnection line between the seller's province and the buyer's province. The execution of bilateral transactions will affect the intraday plan of the interconnection line. To determine the relationship between the power transmission path of bilateral market transactions and the interconnection line plan, it is necessary to consider whether the positive direction definition of the interconnection line plan is consistent with the power transmission direction of the transaction between the buyer and seller. The relationship between the power transmission path of bilateral transactions and the interconnection line of the route can be described by formula (1).

[0045] (1) In the formula, To superimpose the bilateral transaction components on the contact line plan, For contact line Initial contact line plan; It is a bilateral trading route and contact line The correlation coefficient is 1 if the bilateral transaction path is consistent with the default positive direction of the contact line, and -1 if it is opposite to the default positive direction. If the transaction path does not pass through the contact line, it is 0. For bilateral market transactions Transaction power.

[0046] like Figure 2 As shown in the figure, nodes A, B, C, and D are provinces in the North China region, and nodes E, F, and G are external neighboring provinces. The arrows of the contact lines in the figure indicate their positive directions. , , , , , the external interconnection lines of the North China Power Grid are generally cross-provincial DC transmission lines, named , , .like Figure 2 As shown in the figure, a bilateral market transaction was concluded from Province A to Province F. The transmission path is: Province A passes through the interconnection line (Power transmission direction and positive direction) and (Power transmission direction and positive direction).

[0047] Optionally, establish a dictionary table that associates the names of various bilateral market transaction components with the contact lines of the channels, including: According to the transmission paths of various bilateral market transactions through the North China Power Grid, a dictionary table of associations between the names of typical bilateral market transaction components and the interconnection lines is manually defined in advance. The association coefficient defines whether the default positive direction of the interconnection line is consistent with the transmission direction (1: the positive direction of the interconnection line is the same as the transmission direction, -1: the positive direction of the interconnection line is opposite to the transmission direction).

[0048] Tables 1 and 2 list examples of typical transaction component names and contact line association dictionaries for inter-provincial spot market transactions and North China peak-shaving market transactions.

[0049] Table 1. Association dictionary table of typical transaction component names and contact lines in inter-provincial spot markets

[0050] Table 2. Association dictionary table of typical transaction component names and contact lines in North China peak-shaving market

[0051] Tables 3 and 4 list examples of typical transaction component names and contact line association dictionaries for cross-region spot market transactions and cross-region transfer market transactions.

[0052] Table 3. The dictionary table of typical transaction component names and contact lines in the cross-region spot market

[0053] Table 4. The dictionary table of typical transaction component names and contact lines in the inter-regional transfer market

[0054] Use the names of bilateral market transaction components to perform fuzzy matching in the transaction component name-tie line association dictionary table, search for the power transmission path that the transaction may pass through, and search for the tie lines and their association coefficients along the transaction path. Figure 4 The steps for matching the component names and the contact line association dictionary table for various bilateral market transactions shown in are as follows: "Inter-provincial transaction - Province A to Province B", "Inter-provincial transaction - Province C via Province A to Province B": Using the names of the inter-provincial spot market transaction components, the unique power transmission path can be directly matched in the association dictionary table 1: power transmission path 1 "Inter-provincial transaction - Province A to Province B", path 13 "Inter-provincial transaction - Province C via Province A to Province B" (including the names of all the interconnecting lines along the power transmission path and their association coefficients).

[0055]

[0056] "Peak shaving transaction - Province D to Province C": Using its peak shaving market transaction component name, it can be directly matched to the unique power transmission path in the association dictionary table 2: Power transmission path 10 "Peak shaving transaction - Province D to Province C" (including all the interconnection line names and their association coefficients along the power transmission path).

[0057]

[0058] "Inter-regional transaction - Province A sends electricity to Province F + DC system FB": Use the name of the inter-regional transaction component to perform fuzzy matching in the association dictionary table 3. According to the keywords such as "inter-regional transaction" (transaction type), "-Province A" (seller's province), "send electricity to Province F" (buyer's province), and "+DC system FB" (via DC system), fuzzy matching can be found to 2 power transmission paths: Power transmission path 1 "Inter-regional transaction - Province A sends electricity to Province F via Province B + DC system FB", and power transmission path 2 "Inter-regional transaction - Province A sends electricity to Province F via Province D + DC system FB" (including all the contact line names and their correlation coefficients along the power transmission path). In the case where the power transmission path is not unique, the dispatcher manually determines whether to transmit electricity through one path or distribute the electricity through multiple paths in proportion to complete the entire transaction volume. For example, the dispatcher can choose path 1 with a shorter power transmission distance based on experience to complete the transaction.

[0059]

[0060] "Inter-regional transfer - Province E to Province G + DC system CE + DC system DG": Use the name of the inter-regional transfer component to perform fuzzy matching in the associated dictionary table 4. According to the keywords such as "inter-regional transfer" (transaction type), "-Province E" (seller's province), "to Province G" (buyer's province), "+DC system CE + DC system DG" (via DC system), fuzzy matching can be found to 2 power transmission paths: Power transmission path 5 "Inter-regional transfer - Province E via Province D to Province G + DC system CE + DC system DG", and power transmission path 13 "Inter-regional transfer - Province E via Province A to Province G + DC system CE + DC system DG". In the case where the power transmission path is not unique, the dispatcher can choose path 5 with a shorter power transmission distance based on experience to complete the transaction.

[0061]

[0062] In the case where the transmission path is not unique, the dispatcher can also choose to distribute the transaction volume in proportion and complete the transaction through these two transmission paths. Figure 3 The inter-regional transfer market transaction shown in "Inter-regional transfer -F province to H province + DC system FB + DC system CE + DC system EH": Use its inter-regional transfer component name to perform fuzzy matching in the associated dictionary table 4, and according to the keywords such as "inter-regional transfer" (transaction type), "-F province" (seller's province), "to H province" (buyer's province), "+DC system FB + DC system CE + DC system EH" (via DC system), fuzzy matching can be found to two power transmission paths: Power transmission path 9 "Inter-regional transfer -F province via A province to H province + DC system FB + DC system CE + DC system EH", and power transmission path 10 "Inter-regional transfer -F province via D province to H province + DC system FB + DC system CE + DC system EH".

[0063]

[0064] S3. Based on the initial interconnection line plan values ​​and correlation coefficients of each interconnection line corresponding to each power transmission path, as well as the transaction volume of each bilateral market transaction, the interconnection line plan values ​​of each interconnection line are calculated respectively, and the interconnection line plan is adjusted within the day according to the interconnection line plan values.

[0065] In step S3, when each bilateral market transaction corresponds to only one power transmission path, the initial tie line plan value of each tie line corresponding to each power transmission path is constructed as a first matrix of n×1, each correlation coefficient is constructed as a second matrix of n×m, and the transaction volume of each bilateral market transaction is constructed as a third matrix of m×1; wherein n represents the number of tie lines that need to adjust the tie line plan under the current situation, m represents the number of bilateral market transactions, and the elements of each row of the second matrix are the correlation coefficients between the tie line corresponding to the row and each bilateral market transaction respectively; the second matrix and the third matrix are multiplied and then added to the first matrix to obtain a matrix representing the tie line plan value of each tie line.

[0066] In step S3, if the current bilateral market transaction corresponds to two or more power transmission paths, the transaction volume is allocated to each power transmission path of the current bilateral market transaction according to a preset proportional coefficient, and the interconnection line plan value of each interconnection line corresponding to each power transmission path of the current bilateral market transaction is calculated based on the allocated transaction volume.

[0067] Specifically, based on the allocated transaction volume, the tie line plan value of each tie line corresponding to each power transmission path of the current bilateral market transaction is calculated respectively, including: The initial tie-line plan values ​​of each tie-line corresponding to each current power transmission path are constructed as a fourth matrix of k×1, the correlation coefficients are constructed as a fifth matrix of k×a, and the transaction volumes of each bilateral market transaction are constructed as a sixth matrix of a×1; wherein k represents the number of tie-line plans that need to be adjusted under the current circumstances, and a represents the number of power transmission paths corresponding to the current bilateral market transactions; the elements of each row of the fifth matrix are, in turn, the correlation coefficients of the tie-lines corresponding to the row and the transaction volumes allocated according to the proportional coefficients of the current bilateral market transactions; the rows of the sixth matrix are the transaction volumes allocated according to the corresponding proportional coefficients; the fifth matrix and the sixth matrix are multiplied and then added to the fourth matrix to obtain a matrix representing the tie-line plan values ​​of each tie-line corresponding to the current bilateral market transactions.

[0068] As an example, for the case of a unique transmission path that can be matched, the tie line association matrix matched by various bilateral transactions is , and substituting it into formula (1) can calculate the planned adjustment value of each tie line.

[0069] (2) In the formula, The transaction volume of “inter-provincial transactions - sending from Province A to Province B”; The transaction volume of “Inter-provincial transaction - from Province C to Province B”; The transaction volume of "Peak Shaving Transaction - Province D to Province C" The transaction volume of "cross-region transaction - Province A sends to Province F + DC system FB" It is the transaction volume of “cross-region transfer - Province E to Province G + DC system CE + DC system DG”; , , , , is the initial tie line planning value; , , , , It is the planned value of the contact line for superimposing the transaction volume of various bilateral transactions.

[0070] As an example, if the transmission path is not unique, the dispatcher can choose to calculate the transaction volume according to the proportional coefficient.

[0072] In an optional embodiment, the contact line plan modification record of each bilateral transaction is saved, and the completion status of bilateral transactions is counted on a daily basis for the settlement of bilateral transactions at the end of the month. Figure 5 shown.

[0073] Through sufficient on-site investigation and according to actual operation requirements, the above scheme proposes a method for automatic adjustment of intraday tie line plans suitable for large-scale bilateral market trading environments. Compared with the manual adjustment method of traditional tie line plans, the present invention realizes that after a large number of intraday bilateral market transactions are completed, the tie line plan management software assists the dispatcher to quickly superimpose various bilateral transaction components to the tie line plan of the route, and automatically considers whether the bilateral transaction power transmission direction is consistent with the positive direction of the tie line plan, to ensure the correctness of the bilateral transaction components superimposed on the tie line plan. Dispatchers are freed from a large amount of repetitive work in adjusting tie line plans, greatly improving the work efficiency of power grid dispatchers. This patent has been applied to the tie line plan management software of the North China Power Grid and put into actual operation of the power grid.

[0074] In an optional embodiment, a method for adjusting a daily contact line plan in a large-scale bilateral transaction environment is also provided, including: S100, determining the correlation between the power transmission path for bilateral market transactions and the interconnection line; S200, establishing a dictionary table associating the names of typical transaction components in various bilateral markets with the tie lines through which the power transmission path passes; S300. Use the names of bilateral market transaction components to perform fuzzy matching of names in the associated dictionary table of transaction component names and contact lines, search for all power transmission paths that the transaction may pass through, and for bilateral transactions that can match a unique power transmission path, go to step S400; for bilateral transactions that match multiple power transmission paths, the dispatcher manually determines whether to transmit power through one path or distribute power through multiple paths in proportion to complete the total transaction volume.

[0075] S400, forming a correlation matrix between the interconnection line and various bilateral transactions according to the power transmission path determined in step S300; substituting the transaction volume of various bilateral transactions into the interconnection line plan adjustment formula, and calculating the interconnection line plan after superimposing various bilateral transactions.

[0076] S500. Save the modification record of the contact line plan for each bilateral transaction, and count the completion status of the bilateral transactions on a daily basis for the settlement of bilateral transactions at the end of the month.

[0077] The steps of this solution are further explained and illustrated below in conjunction with a specific embodiment. Figure 6 As shown, the specific steps are as follows: Step 1: Read the association information of relevant provinces and tie lines of the North China Power Grid. Tie lines include information such as the sending-end province, receiving-end province, and default positive direction of intra-region tie lines and cross-regional DC transmission lines; the names of provinces within the North China Power Grid and provinces outside the North China region; Step 2: Establish a dictionary table that associates the names of various bilateral market transaction components with the route connection lines. The bilateral market transactions involved include inter-provincial spot market transactions, North China peak-shaving market transactions, inter-regional spot market transactions, and inter-regional transfer market transactions. It should be noted that the names of bilateral market transaction components are composed of transaction type, seller province, buyer province, and DC system of the route. If there are multiple transmission routes from the seller province to the buyer province, it is necessary to add the description "through a certain province" to the transaction component name to clarify the province passed through.

[0078] It is necessary to manually define the association dictionary table of bilateral market transaction component names and route interconnection lines based on all power transmission paths of various bilateral market transactions, and establish a transaction component name-interconnection line association dictionary table based on transaction types such as inter-provincial spot market transactions, North China peak-shaving market transactions, cross-regional spot market transactions, and cross-regional transfer market transactions.

[0079] Step 3: Read the initial planned value of the tie line plan. The daily planned value of each tie line is generally 96 points.

[0080] Step 4: Read the name and volume of bilateral market transaction components. The bilateral market transaction volume is generally 96 points. Step 5: Use the bilateral market transaction component name to perform fuzzy matching of the transaction name in the transaction component name-interconnection line association dictionary table to search for the power transmission path that the transaction may pass through.

[0081] Step 6: For bilateral transactions that can match a unique transmission path, substitute the bilateral transaction volume into formula (4) to calculate the interconnection line plan value after superimposing various bilateral market transaction components.

[0082] Step 7: For bilateral transactions that match multiple transmission paths, the dispatcher manually determines the transmission ratio coefficients of the multiple transmission paths, allocates the transaction volume in proportion, substitutes it into formula (4), and calculates the planned value of the interconnection lines of the multiple transmission paths after superimposing the components of the bilateral market transaction.

[0083] Step 8: Save the modification records of the contact line plan for each bilateral transaction, and count the completion status of bilateral transactions on a daily basis for the settlement of bilateral transactions at the end of the month.

[0084] Step 9: Determine whether there are any new bilateral market transactions. If so, jump back to step 4 to perform relevant automatic adjustment calculations.

[0085] In the simulation example, some interconnection line plan data of the North China Power Grid in 2023 were used to verify the automatic adjustment method of intraday interconnection line plans in a large-scale bilateral market trading environment, and various bilateral trading components were automatically superimposed on the interconnection line plans through which the transmission path passed.

[0089] Through the above examples, the automatic adjustment method of the connecting line plan proposed in this scheme, which is applicable to the large-scale bilateral market transaction environment, is verified. Under the premise of ensuring the rigid execution of the bilateral market transaction contract, the automatic adjustment of the connecting line plan of various bilateral market transaction component pathways is realized, which greatly improves the work efficiency of the dispatcher.
