Attached Figure Description

[0062] Figure 1 This is a schematic diagram of the power market transaction clearing system of the present invention. Detailed Implementation

[0063] The present invention will now be described in further detail with reference to the accompanying drawings.

[0064] Example 1

[0065] like Figure 1 As shown, this patent provides a method for exchanging clearing cases in the electricity market, including naming methods, formats, encryption methods, and exchange methods for case exchange files:

[0066] First, the naming convention for case exchange files.

[0067] Case exchange files have the extension .cas and are named "Case ID_Creation Time.cas". The case ID is unique, all uppercase, and contains five fields: region, trading instrument, trading period, effective time, and instance number, separated by underscores, with a fixed length of 30 bytes. The region uses a two-letter code, e.g., Fujian FJ; the trading instrument uses a two-letter code followed by a number, with the number used for classification; common instruments include Electricity (EN), Ancillary Services (AS), Capacity (CA), Transmission Rights (TR), and Generation Rights (GR); the trading period contains three bytes: Multi-day (DX), Day-ahead (D-1), Intraday (D+0), and Real-time (T+0); the effective time format is YYYYMMDDHHMM, representing year, month, day, hour, and minute respectively. For multi-day and day-ahead markets, HHMM is the timestamp of case generation; finally, the number is the code for the clearing application, e.g., CASE0 represents the main clearing application, CASE1 represents the minor application 1, CASE2 represents the minor application 2, and so on.

[0068] Second, the format of the case exchange files.

[0069] The case exchange file is encrypted. The decompressed file includes a file header, exported case information, encrypted and compressed case files, and a verification code.

[0070] The file header contains a signature, the length of the exported case information, and the length of the encrypted and compressed case file. The signature is 0xcecfcecf.

[0071] The exported case information includes Case ID, Transaction Sequence ID, Case Name, Effective Time, Expiration Time, Creation Time, Modification Time, Remarks, Case Application Number, and Case File Path.

[0072] The encrypted and compressed case files are encrypted and compressed case data that needs to be exchanged. The data files are encrypted by the case service, decrypted by the case service, and stored in the file database of the trading platform.

[0073] The checksum is generated by the CRC32 algorithm and is the result of the CRC32 algorithm calculation of the file header, exported case information, and encrypted and compressed case file.

[0074] Third, case compression and encryption methods.

[0075] A two-tiered encryption method is employed, involving both the server and client sides. Both server and client encryption utilize dynamic passwords, consisting of a randomly generated static password and a dynamic password specific to the case study. The server encrypts and compresses the case study files, storing the compressed files in a file database. The client retrieves the files from the database, generates a case exchange file according to the case exchange format, and encrypts the exchange file as well. The decryption process begins with the client program decrypting the exchange file. Upon successful decryption, the file is verified for validity, correctness, and integrity. If verified, it is stored in the database. Then, when the trading platform loads a case study, it invokes the case study service to decrypt and decompress the file, completing the case loading and enabling case analysis.

[0076] Fourth, the method for exchanging case files.

[0077] Step 1: The server in the operating environment compresses and encrypts the data from the power market optimization and clearing process in the platform database into a case information file according to the data type and stores it.

[0078] Step 2: The client in the runtime environment extracts the stored case information file, then encrypts it to form a case exchange file, and outputs it to the target location;

[0079] Step 3: The client in the laboratory environment reads, decrypts, decompresses, and verifies the case exchange file at the target location to form a case file, which is then stored on the server.

[0080] Step 4: The loading module on the server side of the laboratory environment extracts and decompresses the stored case information file into optimized clearing data and stores it in the platform database of the laboratory environment. The case information exchanged in this invention adopts a step-by-step encryption method to ensure the security of the core data of market members in the case file, ensure that the case file can only be exchanged within the trading platform, and at the same time, the multi-encrypted case exchange file cannot be decrypted offline.

[0081] Specifically:

[0082] Step 1: On the power market trading platform A, through the case service, the input, output and intermediate process data of power market optimization and clearing are categorized and output to a local temporary folder according to physical model, economic model, planning data, declaration data, clearing data and statistical data. Then, the entire folder is encrypted and compressed to generate encrypted and compressed case files, which are stored in the file database. At the same time, a record is added to the case information table, storing the case information of the specified case ID.

[0083] Step 2: On the power market trading platform A, the client program is invoked through the interface to read the case information of the specified case ID from the case information table in the database, obtain the encrypted and compressed case file from the file database, generate the case exchange file according to the case exchange format, encrypt the case exchange file, and output it to a local file according to the file naming convention.

[0084] Step 3: On the power market trading platform B, the client program is called through the interface to read the case exchange file exchanged locally, decrypt the case exchange file, and verify the validity, correctness and integrity of the file after successful decryption. If the verification is successful, the case information is written into the case information table of the database and the encrypted and compressed case data is stored in the file database.

[0085] Step 4: On the power market trading platform B, the server program is called through the interface to read the encrypted and compressed case file from the file database, decrypt and decompress it to the local temporary folder, generate case input, output and intermediate data files, and write them into the corresponding data tables in the database in the order of physical model, economic model, planning data, declaration data, clearing data and statistical data, thus completing the case loading process.

[0086] Example 2:

[0087] A typical application scenario for this invention is the exchange of data between an electricity market trading platform and a laboratory simulation verification platform. The entire embodiment involves four steps, including:

[0088] Step 1: The server in the operating environment compresses and encrypts the data from the power market optimization and clearing process in the platform database into a case information file according to the data type and stores it.

[0089] Step 2: The client in the runtime environment extracts the stored case information file, then encrypts it to form a case exchange file, and outputs it to the target location;

[0090] Step 3: The client in the laboratory environment reads, decrypts, decompresses, and verifies the case exchange file at the target location to form a case file, which is then stored on the server.

[0091] Step 4: The loading module on the server side of the laboratory environment extracts and decompresses the stored case information file into optimized clearing data and stores it in the platform database of the laboratory environment. The case information exchanged in this invention adopts a step-by-step encryption method to ensure the security of the core data of market members in the case file, ensure that the case file can only be exchanged within the trading platform, and at the same time, the multi-encrypted case exchange file cannot be decrypted offline.

[0092] Specifically as follows:

[0093] Suppose that on August 4, 2019, the spot market bidding for electricity in a certain province (coded as MS) was shut down. Operator Xiao Yang verified and confirmed various data. After confirming that everything was correct, he started the optimization and clearing calculation, which was completed at 16:35. Xiao Yang entered the case management screen, clicked "save case" on the operation interface, and subsequently generated a calculation case with the case ID MS_EN1_D-1_E201908051635_CASE0, containing inputs, outputs, and intermediate results such as the physical model, economic model, planned data, declaration data, clearing data, and statistical data.

[0094] Xiao Yang submitted the clearing results to his superiors. After approval by leaders of various departments, the clearing results were officially released at 17:30 that day. After receiving the day-ahead spot market clearing results for August 5, 2019, power plant A's technician, Xiao Wu, checked the electricity volume and price data, which were of most concern to him. He found that the electricity price was significantly lower than the previous day, so he raised questions with the spot trading department.

[0095] At 18:50, Xiao Yang responded to the questions by exporting the case from the spot trading platform, generating a case exchange file MS_EN1_D-1_E201908051635_CASE0_20190804185025.cas, and transferring this file to the laboratory's power market simulation verification platform. He then imported and loaded the case, restarted the optimized clearing calculation, and completed the calculation at 19:05, saving the case as MS_EN1_D-1_E201908051905_CASE1. He then switched to the case comparison screen, loading two cases, MS_EN1_D-1_E201908051635_CASE0 and FJ_EN1_D-1_E201908051905_CASE1. Clicking the comparison button and viewing various data, results, and statistical indicators, he found that the two calculation results were completely consistent. The clearing result from the spot trading platform was entirely correct, and there were no technical issues.

[0096] Finally, the relevant departments conducted a comprehensive analysis of transaction declarations, power load, incoming power, outgoing power, and transmission channels, and found the real reason why the electricity price was lower than yesterday. Power Plant A agreed with the response from the spot trading department.
