For example, through the relationship between key entropy, key length and pulse noise in historical data and signal strength, a mapping set of key entropy, key length and pulse noise and their corresponding weights is established respectively. By inputting real-time key entropy, key length and pulse noise, the corresponding preset key entropy influence weight factor, preset key length influence weight factor and preset pulse noise influence weight factor in the mapping set are obtained.

[0079] The preset RF strength correction factor, the preset signal power correction factor and the preset virtual power plant operation data encryption efficiency correction factor can be obtained through the virtual power plant database, which represents the proportion of RF strength, signal power and virtual power plant operation data encryption efficiency in the virtual power plant operation data encryption reliability assessment index. The preset RF strength correction factor, the preset signal power correction factor and the preset virtual power plant operation data encryption efficiency correction factor can also be obtained through a mapping relationship. For example, through the relationship between the RF strength, signal power and virtual power plant operation data encryption efficiency in historical data and the virtual power plant operation data update frequency, a mapping set of RF strength, signal power and virtual power plant operation data encryption efficiency and their corresponding weights is established respectively. By inputting the real-time RF strength, signal power and virtual power plant operation data encryption efficiency, the corresponding preset RF strength correction factor, preset signal power correction factor and preset virtual power plant operation data encryption efficiency correction factor in the mapping set are obtained.

[0080] Signal power is the strength of signal transmission. Higher signal power can resist the influence of pulse noise. The higher the signal power, the smaller the pulse noise. RF strength is related to signal power, which affects the quality and distance of wireless communication. The higher the RF signal strength, the greater the signal power. The higher the key entropy, the smaller the deviation between the key length and the standard value of the key length, which improves the security of encryption and increases the computational complexity of encryption and decryption, thereby affecting the encryption efficiency. The encryption efficiency of virtual power plant operation data is lower. The higher the pulse noise, the efficiency of virtual power plant operation data transmission is reduced, and more error detection and correction mechanisms are required. The optimization of RF strength and signal power can improve the efficiency of data transmission. The smaller the deviation between the RF strength and the standard value of the RF strength, the higher the encryption efficiency of virtual power plant operation data.

[0081] The higher the key entropy, the stronger the randomness of the key, and the better the security of the virtual power plant operation data encryption system. There is a positive correlation between the key entropy and the virtual power plant operation data encryption reliability assessment index, and the larger the virtual power plant operation data encryption reliability assessment index is; the smaller the absolute value of the key length and the key length difference, the larger the key space, and the higher the difficulty of cracking the key. There is a negative correlation between the absolute value of the key length and the key length difference and the virtual power plant operation data encryption reliability assessment index, and the larger the virtual power plant operation data encryption reliability assessment index is; the larger the square of the difference between the pulse noise and the pulse noise standard value, the increase in the error rate of the virtual power plant operation data transmission and the reduction in the reliability of the virtual power plant operation data transmission. There is a negative correlation between the square of the difference between the pulse noise and the pulse noise standard value and the virtual power plant operation data encryption reliability assessment index, and the smaller the virtual power plant operation data encryption reliability assessment index is ; The larger the square of the difference between the RF strength and the standard value of the RF strength, the weaker the anti-interference ability, the square of the difference between the RF strength and the standard value of the RF strength is negatively correlated with the virtual power plant operation data encryption reliability assessment index, and the smaller the virtual power plant operation data encryption reliability assessment index is; the smaller the absolute value of the difference between the signal power and the standard value of the signal power, the better the stability of the signal transmission, the stronger the anti-interference ability, the absolute value of the difference between the signal power and the standard value of the signal power is negatively correlated with the virtual power plant operation data encryption reliability assessment index, and the larger the virtual power plant operation data encryption reliability assessment index is; the greater the virtual power plant operation data encryption efficiency, the faster the virtual power plant operation data encryption and decryption process, the faster the system response speed, the virtual power plant operation data encryption efficiency is positively correlated with the virtual power plant operation data encryption reliability assessment index, and the larger the virtual power plant operation data encryption reliability assessment index is.

[0082] Furthermore, the specific steps of comprehensively analyzing and obtaining the virtual power plant operation data security assessment index are as follows: obtaining the key update frequency of the preset virtual power plant operation data security detection point through the key management server; and obtaining the virtual power plant operation data security assessment index through comprehensive analysis of the virtual power plant operation data transmission monitoring assessment index, the virtual power plant operation data encryption reliability assessment index and the key update frequency.

[0083] In this embodiment, the specific method for analyzing and obtaining the virtual power plant operation data security evaluation index is as follows: ; ; The preset virtual power plant operation data security detection points are numbered in sequence. Indicates the number of the virtual power plant operation data security detection point, , Indicates the total number of numbers of virtual power plant operation data security detection points.

[0084] Represents the virtual power plant operation data security assessment index.

[0085] Indicates The virtual power plant operation data encryption reliability evaluation index of the virtual power plant operation data encryption reliability detection point is calculated.

[0086] Indicates The key update frequency under the virtual power plant operation data security detection point.

[0087] It represents the standard value of key update frequency, which is the preset standard value of key update frequency obtained from the virtual database. If the key update frequency at a certain virtual power plant operation data security checkpoint is greater than the standard value of key update frequency, the faster the key update frequency, the greater the virtual power plant operation data transmission delay; if the key update frequency at a certain virtual power plant operation data security checkpoint is lower than the standard value of key update frequency, the risk of key cracking increases and the security of virtual power plant operation data is reduced.

[0088] Indicates The virtual power plant operation data transmission monitoring evaluation index of the virtual power plant operation data transmission monitoring detection points.

[0089] The reliability assessment index influencing weight factor is encrypted for the preset virtual power plant operation data obtained from the virtual power plant database.

[0090] The preset key update frequency obtained from the virtual power plant database affects the weight factor.

[0091] It is the impact weight factor of the preset virtual power plant operation data transmission monitoring and evaluation index obtained from the virtual power plant database.

[0092] The weight factors affecting the reliability assessment index of the encryption of the preset virtual power plant operation data, the weight factors affecting the frequency of key updates, and the weight factors affecting the monitoring and assessment index of the operation data transmission of the preset virtual power plant can be obtained through the virtual power plant database, indicating the proportion of the virtual power plant operation data encryption reliability assessment index, the key update frequency, and the virtual power plant operation data transmission monitoring and assessment index in the virtual power plant operation data security assessment index. The weight factors affecting the reliability assessment index of the encryption of the preset virtual power plant operation data, the weight factors affecting the frequency of key updates, and the weight factors affecting the monitoring and assessment index of the operation data transmission of the preset virtual power plant can also be obtained through mapping relationships, such as through historical data. The relationship between the virtual power plant operation data encryption reliability assessment index, key update frequency and virtual power plant operation data transmission monitoring assessment index and encryption delay is established by respectively establishing a mapping set of the virtual power plant operation data encryption reliability assessment index, key update frequency and virtual power plant operation data transmission monitoring assessment index and their corresponding weights. By inputting the real-time virtual power plant operation data encryption reliability assessment index, key update frequency and virtual power plant operation data transmission monitoring assessment index, the corresponding preset virtual power plant operation data encryption reliability assessment index influencing weight factor, preset key update frequency influencing weight factor and preset virtual power plant operation data transmission monitoring assessment index influencing weight factor in the mapping set are obtained.

[0093] Table 1 is an example table of the virtual power plant operation data security assessment index. The example parameters in Table 1 only take the parameters under one virtual power plant operation data security detection point for example. Set to 0.4, weight factor Set to 0.3, weight factor Set to 0.3, The standard value of the key update frequency is 2, as shown in Table 1.

[0094] Table 1 Example of virtual power plant operation data security assessment index

[0095] The key update frequency affects the reliability assessment index of virtual power plant operation data encryption. The higher the key update frequency, the higher the security of the encryption system. If the key is cracked, the attacker can only access limited virtual power plant operation data. The increased key update frequency, the greater the virtual power plant operation data encryption reliability assessment index; the slower the key update frequency, the higher the complexity of virtual power plant operation data transmission, thereby affecting the virtual power plant operation data transmission rate and delay, the greater the virtual power plant operation data transmission monitoring assessment index; the higher the virtual power plant operation data encryption reliability assessment index, the higher the security of virtual power plant operation data transmission, and the lower the virtual power plant operation data transmission monitoring assessment index.

[0096] It can be seen from Table 1 that the higher the reliability evaluation index of virtual power plant operation data encryption, the stronger the security of the virtual power plant operation data encryption system, the virtual power plant operation data encryption reliability evaluation index is positively correlated with the virtual power plant operation data security evaluation index, and the larger the virtual power plant operation data security evaluation index is; the smaller the absolute value of the key update frequency and the key update frequency standard value difference is, the key update frequency and the key update frequency standard value difference is negatively correlated with the virtual power plant operation data security evaluation index, and the larger the virtual power plant operation data security evaluation index is; the higher the virtual power plant operation data transmission monitoring evaluation index is, the worse the security of the virtual power plant operation data during transmission, the virtual power plant operation data transmission monitoring evaluation index is negatively correlated with the virtual power plant operation data security evaluation index, and the smaller the virtual power plant operation data security evaluation index is.

[0097] like Figure 2 As shown, it is a schematic diagram of the virtual power plant operation data security evaluation index function provided by an embodiment of the present invention; x is the positive semi-axis of the horizontal coordinate, y is the positive semi-axis of the vertical coordinate, and the weight factor Set to 0.4, weight factor Set to 0.3, weight factor Set to 0.3, The standard value for key update frequency is 2.

[0098] Curve a indicates that if the key update frequency is set to a fixed value of 1, the virtual power plant operation data transmission monitoring evaluation index is set to a fixed value of 1, the virtual power plant operation data encryption reliability evaluation index is x, and the virtual power plant operation data security evaluation index is y, the virtual power plant operation data security evaluation index increases with the increase of the virtual power plant operation data encryption reliability evaluation index.

[0099] Furthermore, the specific steps for optimizing and adjusting the virtual power plant operation data transmission monitoring method are as follows: if the virtual power plant operation data transmission monitoring and evaluation index is lower than or equal to the first threshold value of the virtual power plant operation data transmission monitoring and evaluation index, there is no need to optimize and adjust the virtual power plant operation data transmission monitoring method; if the virtual power plant operation data transmission monitoring and evaluation index is greater than the first threshold value of the virtual power plant operation data transmission monitoring and evaluation index, equalization and filtering signal processing technology are used to reduce the impact of pulse noise on virtual power plant operation data transmission, forward secrecy can be achieved by using ECDHE or DHE cipher suites, and password identification means are used.

[0100] In this embodiment, it is assumed that the virtual power plant operation data transmission monitoring and evaluation index is 90, and the first threshold value of the virtual power plant operation data transmission monitoring and evaluation index is 80. Through equalization and filtering technology, the impact of pulse noise on the virtual power plant operation data transmission is reduced, and the clarity and accuracy of data transmission are improved. ECDHE or DHE cipher suites are used. ECDHE, or DHE, cipher suites can achieve forward secrecy. Even if the long-term key is leaked, the confidentiality of past communications is still protected. Through password identification means, the identities of both parties in communication can be verified to prevent unauthorized access and data tampering. Password identification means, such as using digital certificates for identity authentication, can use digital certificates to verify the identities of senders and receivers in virtual power plant operation data transmission. For example, when the virtual power plant sends data to the data center, the private key is used to sign the data and a digital certificate is attached. After the data center receives the data, it will use the public key of the virtual power plant, which can be obtained from the digital certificate to verify the authenticity of the signature, thereby confirming the source of the data. Similarly, when the data center sends data to the virtual power plant, a similar mechanism is used to verify the identity.

[0101] Furthermore, the specific steps for optimizing and adjusting the virtual power plant operation data encryption reliability method are as follows: if the virtual power plant operation data encryption reliability evaluation index is greater than or equal to the second threshold value of the virtual power plant operation data encryption reliability evaluation index, there is no need to optimize and adjust the virtual power plant operation data encryption reliability method; if the virtual power plant operation data encryption reliability evaluation index is lower than the second threshold value of the virtual power plant operation data encryption reliability evaluation index, end-to-end encryption is implemented, and only the sender and receiver can decrypt the virtual power plant operation data, and HSM is introduced to protect the encryption key.

[0102] In this embodiment, it is assumed that the virtual power plant operation data encryption reliability evaluation index is 70, and the second threshold value of the virtual power plant operation data encryption reliability evaluation index is 80. End-to-end encryption is implemented to ensure that only the sender and the receiver can decrypt the virtual power plant operation data to prevent unauthorized access to the data during transmission. A pair of RSA keys (public key and private key) is generated using HSM. The public key is used to encrypt data, and the private key is used to decrypt data. The private key is securely stored in the HSM and is not exported to any other device or medium. When the sender needs to send data, the data is encrypted using the receiver's public key. The encrypted data is transmitted to the receiver through a secure channel. The receiver uses the private key stored in the HSM to decrypt the data. In this way, only the sender and the receiver can encrypt and decrypt the data because only the sender and the receiver have the corresponding keys. HSM ensures the security of the key, prevents the leakage or abuse of the key, and ensures the integrity and confidentiality of the sensor data.

[0103] Furthermore, the specific steps of optimizing and adjusting the method for the security of virtual power plant operation data are as follows: extracting the comprehensive threshold of the virtual power plant operation data security assessment index in the virtual power plant database, and comparing the virtual power plant operation data security assessment index with the comprehensive threshold of the virtual power plant operation data security assessment index; if the virtual power plant operation data security assessment index is greater than or equal to the comprehensive threshold of the virtual power plant operation data security assessment index, there is no need to optimize and adjust the method for the security of virtual power plant operation data.

[0104] Furthermore, the method for optimizing and adjusting the security of virtual power plant operation data also includes: if the virtual power plant operation data security assessment index is lower than the comprehensive threshold of the virtual power plant operation data security assessment index, the data is classified and labeled, security measures are taken according to the sensitivity of the virtual power plant operation data, and multi-factor authentication is implemented.

[0105] In this embodiment, it is assumed that the virtual power plant operation data security assessment index is 60, and the comprehensive threshold of the virtual power plant operation data security assessment index is 80, indicating that the virtual power plant operation data security is insufficient, then the data needs to be classified and labeled, and multi-factor authentication is implemented, for example: the virtual power plant operation data is divided into different categories, such as public data, internal data and confidential data; public data: non-sensitive data, such as weather forecast information; internal data: data that requires limited access, such as employee information; confidential data: highly sensitive data, such as power load forecast, user electricity consumption data; different security labels are applied to different categories of data; public data: unlabeled or marked as "public"; internal data: marked as "internal"; confidential data: marked as "confidential"; different access control policies are implemented according to data labels; public data: open access to all users; internal data: only authorized employees can access; confidential data: only high-level authorized employees can access; confidential data is encrypted to ensure the security of data during transmission and storage. The steps to implement multi-factor authentication are: the user enters the username and password; the user enters the dynamic password generated by the token; the user verifies through fingerprint or facial recognition; for example, suppose an employee of a virtual power plant needs to access confidential data, the following is a detailed authentication process: Step 1: Password verification: the employee enters the username and password; the system verifies whether the username and password are correct; Step 2: Token verification: If the password verification is successful, the system requires the employee to enter the dynamic password generated by the token; the system verifies whether the dynamic password is correct; Step 3: Biometric verification: If the token verification is successful, the system requires the employee to perform fingerprint or facial recognition, and the system verifies whether the biometric information is correct. Through the above steps, employees can access confidential data, and improve the security of virtual power plant operation data through data classification and tagging, as well as multi-factor authentication.
