[0027] The account data processing module 102 is connected to the user login module 101, the daily transaction power cost calculation module 105 and the monthly transaction power cost calculation module 106;

[0028] The electricity price data pulling module 103 is connected to the user login module 101, the daily transaction electricity cost calculation module 105 and the monthly transaction electricity cost calculation module 106;

[0029] The transaction data processing module 104 is connected to the user login module 101, the daily transaction energy and electricity fee calculation module 105 and the monthly transaction energy and electricity fee calculation module 106;

[0030] The daily transaction electricity fee calculation module 105 is connected to the account data processing module 102, the electricity price data extraction module 103, the transaction data processing module 104 and the market-based power plant non-time-sharing settlement module 107;

[0031] The monthly transaction electricity fee calculation module 106 is connected to the account data processing module 102, the electricity price data extraction module 103, the transaction data processing module 104 and the market-based power plant non-time-sharing settlement module 107;

[0032] The market-oriented power plant non-time-sharing settlement module 107 is connected to the daily transaction power fee calculation module 105, the monthly transaction power fee calculation module 106 and the settlement list review and query module 108;

[0033] The settlement list review and query module 108 is connected to the user login module 101 and the market-based power plant non-time-sharing settlement module 107.

[0034] The user login module 101 is used to receive the login information input by the user when logging into the system, and verify the user's system login qualification based on the login information, and send a login permission instruction after the verification is passed, so that the user can log in to the system based on the login permission instruction to execute the system permissions corresponding to the system login qualifications. Among them, users include power trading centers and market-oriented power plants. The system login qualifications of the power trading center are system managers, and the system login qualifications of the market-oriented power plants are system viewers. The power trading center has the system permissions to obtain data for non-time-sharing settlement and store it in the system database, as well as to form non-time-sharing settlement lists and issue orders. The market-oriented power plant has the system permissions to view its own non-time-sharing settlement lists. The power trading center corresponds to a marketing system, a data center and a power trading subsystem.

[0035] In the above embodiment of the present application, through the data interface provided by the marketing system, data center and power trading subsystem, the system can pull in actual online power consumption, electricity price-related data, transaction contract data and other data for subsequent calculation of market-oriented power plant settlement-related data.

[0036] Specifically, the user logs into the system and inputs login information. After the user login module 101 passes the verification, the user is allowed to log into the system. Otherwise, the user is not allowed to log into the system. The categories of users include power trading centers and market-oriented power plants. The power trading center, as the system administrator, can control the preparation and processing of system-related data, as well as non-time-sharing settlement, order issuance, etc. The market-oriented power plant, as a system user, can view its own non-time-sharing settlement data and list. In particular, when performing verification, when a user tries to log in to the system, the system first needs to receive the login information entered by the user. Information such as: User name, a string used to uniquely identify the user's identity. Password, a key set by the user for identity verification. In particular, the system may also require the user to enter other auxiliary verification information, such as: verification code, a random character or graphic used to prevent automated login. Dynamic password, a password that changes over time to increase login security.

[0037] When the system receives login information from a user, it needs to verify the information to confirm the user's identity and login qualifications. The verification process may include the following steps:

[0038] Information matching: The username and password entered by the user are matched with the user information stored in the system. If a match is successful, it indicates that the user may be a legitimate system user.

[0039] Password Verification: The system can encrypt and store passwords. During verification, the system encrypts the password entered by the user and compares it with the stored encrypted password. If the two match, the password verification is successful.

[0040] Additional verification (if applicable): If the system requires the user to enter other auxiliary verification information, such as a verification code, dynamic password or biometric information, the system also needs to verify this information.

[0041] Permission check: After confirming the user's identity, the system also needs to check the user's permission level to determine whether the user has the right to access the system resources or functions currently being accessed.

[0042] Based on the verification results, the system will send a login result notification to the user, specifically:

[0043] Successful login: If the user's identity authentication is successful and the permissions meet the requirements, the system will allow the user to log in and display the system interface or related functions to the user.

[0044] Login failure: If the user's identity authentication fails (such as incorrect username or password, incorrect verification code, etc.) or the permissions do not meet the requirements, the system will reject the user's login request and display the corresponding error message to the user.

[0045] In one specific embodiment: 1. User Input: The user enters their username and password on the login screen. 2. Information Receiving: The system receives the username and password entered by the user. 3. Information Matching: The system matches the username entered by the user with the usernames stored in the system. 4. Password Verification: If the username matches, the system encrypts the password entered by the user and compares it with the stored encrypted password. 5. Permission Check: The system checks the user's permission level. 6. Result Notification: Based on the verification result, the system sends a notification to the user indicating a successful or failed login.

[0046] In this way, the system can effectively receive the login information entered by the user and verify the user's system login qualifications based on this information.
