[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations.

[0062] The distributed resource monitoring terminal data trust method for power auxiliary services provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the edge cluster master station 101, the aggregator 102 and the edge gateway 103 form a consensus chain; the edge gateway 103 is used to isolate the edge cluster master station 101 and the aggregator 102; the edge gateway 103 is also connected to the resource monitoring terminal 104; the resource monitoring terminal 104 is also connected to the power distributed resource 105.

[0063] In one embodiment, Figure 2 As shown in the figure, a distributed resource monitoring terminal data trust method for power auxiliary services is provided. Figure 1 The resource monitoring terminal in the example is used as an example to illustrate, including the following steps:

[0064] Step S201, obtaining the end source data of the distributed power resources.

[0065] Among them, distributed power resources refer to energy supply systems that arrange power generation systems in a small-scale, decentralized manner near the user side and can operate independently or in conjunction with the grid.

[0066] Specifically, the resource monitoring terminal is deployed at each power distributed resource, responsible for collecting real-time data of each power distributed resource and performing necessary calculations to obtain the end source data of each power distributed resource.

[0067] Step S202, obtaining the blockchain certificate of the consensus chain where the edge gateway is located through the edge gateway connected to the resource monitoring terminal.

[0068] Among them, the edge gateway is a gateway device deployed at the edge of the power network (such as the smart grid).

[0069] Step S203: According to the blockchain certificate, the end source data is signed to obtain the signed backend source data.

[0070] Among them, blockchain certificate is a digital certificate recorded and stored using blockchain technology; blockchain certificate has a high degree of authenticity and immutability, ensuring the accuracy and credibility of information (such as end-source data).

[0071] Specifically, the resource monitoring terminal can request the blockchain certificate of the consensus chain to which the end source data is to be uploaded through the edge gateway connected to it, and then use the blockchain certificate to add a digital signature to the end source data, so that the resource monitoring terminal obtains the signed backend source data.

[0072] Step S204, sending the signature backend source data to the edge gateway to process the signature backend source data on the chain.

[0073] Specifically, the resource monitoring terminal sends the signature backend source data to the edge gateway, and then the edge gateway sends the signature backend source data to the consensus chain, so that the signature backend source data can be processed on the chain in the consensus chain. Among them, the chain refers to storing data (such as signature backend source data or end source data) in the consensus chain, and ensuring the immutability and uniqueness of the data through the consensus mechanism of the consensus chain, thereby improving the credibility of the source data.

[0074] In the above-mentioned distributed resource monitoring terminal data trust method for power auxiliary services, the end source data of the power distributed resources is obtained; the blockchain certificate of the consensus chain where the edge gateway is located is obtained through the edge gateway connected to the resource monitoring terminal; the end source data is signed according to the blockchain certificate to obtain the signed backend source data; the signed backend source data is sent to the edge gateway to process the signed backend source data on the chain. By adopting this method, the end source data of the power distributed resources is signed and then chained by the blockchain certificate of the consensus chain where the edge gateway is located, which can improve the credibility of the source data in the entire collection and transmission link, thereby ensuring the accuracy of the user-side settlement business of the virtual power plant composed of power distributed resources, and providing more reliable data trust support for the application of virtual power plants.

[0075] In one embodiment, the above step S202, through the edge gateway connected to the resource monitoring terminal, obtains the blockchain certificate of the consensus chain where the edge gateway is located, specifically including the following contents: generating a certificate acquisition request according to the device identification information of the resource monitoring terminal, and sending the certificate acquisition request to the edge gateway; receiving the blockchain certificate returned by the edge gateway based on the certificate acquisition request; the blockchain certificate is obtained by requesting the consensus chain through the edge gateway.

[0076] The device identification information refers to a unique identification that can represent the resource monitoring terminal. The device identification information can be a unique device number of the resource monitoring terminal.

[0077] Figure 3 Schematic diagram of the process of obtaining a blockchain certificate for a resource monitoring terminal. Specifically, the resource monitoring terminal sends a certificate acquisition request to the edge gateway according to the unique device number, and then the edge gateway applies for a blockchain certificate from the consensus chain. The consensus chain generates and stores the blockchain certificate, and then returns the generated blockchain certificate to the edge gateway. The edge gateway finally sends the blockchain certificate to the resource monitoring terminal, which is then stored locally.

[0078] In this embodiment, by applying for a blockchain certificate to sign the end source data, and then transmitting the signed backend source data to the edge gateway, the transmission security of the signed backend source data can be improved to prevent it from being tampered with during transmission, thereby ensuring the credibility of the signed backend source data during transmission, thereby improving the data credibility of distributed power resources.

[0079] In one embodiment, Figure 4 As shown, the above step S204, the signature backend source data is processed on the chain, which specifically includes the following contents:

[0080] Step S401, sending a request for uplinking the signature backend source data to the consensus chain through the edge gateway, so that the consensus chain can perform signature verification processing on the signature backend source data to obtain the signature verification result of the signature backend source data.

[0081] Figure 5 The figure is a flowchart for uploading the signature backend source data to the chain. Specifically, the resource monitoring terminal sends the signature backend source data and the chain request to the edge gateway, wherein the chain request carries the request parameter; the request parameter can be the current version verification code of the program and configuration file of the resource monitoring terminal, so that the consensus chain can verify whether the chain request is reliable, such as comparing the current version verification code with the latest version verification code stored in the consensus chain (the original version verification code or the current version verification code stored in the past). The edge gateway forwards the received signature backend source data and chain request to the consensus chain; if the consensus chain receives the signature backend source data and the chain request, it parses the chain request and uses the blockchain certificate stored therein to perform signature verification processing on the signature backend source data to obtain the signature verification result of the signature backend source data.

[0082] Step S402: If the signature verification result indicates that it has passed, the signature backend source data is uploaded to the chain through the consensus chain.

[0083] Specifically, if the signature verification result of the signature backend source data indicates that it has passed, the consensus chain stores the signature backend source data in the edge cluster master station in the consensus chain, that is, the data is on-chain. After the on-chain is completed, the consensus chain returns the on-chain result to the resource monitoring terminal step by step. Among them, the on-chain result is used to indicate whether the signature backend source data is successfully on-chain.

[0084] In this embodiment, by uploading the signature backend source data to the consensus chain, the credibility of the signature backend source data is further improved, thereby improving the data credibility of power distributed resources.

[0085] In one embodiment, the above step S201, obtaining the end source data of the distributed power resources, specifically includes the following contents: collecting the original data of the distributed power resources; processing the original data through the metering chip built into the resource monitoring terminal to obtain the end source data.

[0086] Among them, the metering chip has the ability to process data in the power field.

[0087] Specifically, the resource monitoring terminal is equipped with a high-precision power metering chip. After the resource monitoring terminal collects the raw data of the distributed power resources, it can also pre-process and calculate the raw data through the metering chip, such as calculating the current, voltage, power and other data based on the collected raw data, and then the resource monitoring terminal processes the end source data.

[0088] In this embodiment, the collected raw data is processed by a high-precision metering chip in the power field. The high calculation accuracy of the metering chip can be used to improve the accuracy of the processed end-source data, thereby improving the credibility of distributed power resources in the data collection link.

[0089] In one embodiment, in the above step S201, before obtaining the end source data of the power distributed resources, it also includes: after the resource monitoring terminal is powered on for the first time, the original version verification code of the program and configuration file of the resource monitoring terminal is sent to the edge gateway; according to a preset period, the current version verification code of the program and configuration file is obtained; if it is detected that the current version verification code is different from the original version verification code, the current version verification code is signed and transmitted to the edge gateway.

[0090] Here, power-on means that the resource monitoring terminal has been powered and is in a working ready state.

[0091] Figure 6A flow chart for sending the version verification code of the program and configuration file of the resource monitoring terminal to the edge cluster master station for latching. Specifically, after the resource monitoring terminal is powered on for the first time, it can sign the original version verification code V0 of its program and configuration file and send it to the edge gateway, so that the original version verification code can be forwarded to the edge cluster master station through the edge gateway; the edge cluster master station stores the received original version verification code. After that, the resource monitoring terminal will periodically calculate the current version verification code of the program and configuration file according to the preset period, and determine whether the current version verification code has changed; if the current version verification code has changed, that is, the current version verification code V1 is different from the original version verification code, then the resource monitoring terminal will sign the changed current version verification code and forward it to the edge cluster master station through the edge gateway. After receiving the current version verification code, the edge cluster master station will continue to compare the current version verification code with the original version verification code. If it is detected that the current version verification code is not equal to the original version verification code, it will continue to determine whether it has received an application report for the on-site upgrade program and configuration of the resource monitoring terminal in the historical time period. If it has not received an application report, the edge cluster master station will issue an alarm that the version verification code of the program and configuration file of the resource monitoring terminal is abnormal. Otherwise, the edge cluster master station will store V1 as the latest version verification code of the resource monitoring terminal.

[0092] Furthermore, when the subsequent resource monitoring terminal periodically calculates the current version verification code V2 of the program and configuration file, and detects that the current version verification code V2 is different from V1, it will also sign the current version verification code V2 and send it to the edge cluster master station; the edge cluster master station will compare the newly received current version verification code V2 with the latest stored V1 to determine whether to update the stored version verification code.

[0093] In this embodiment, by sending the version verification code of the program and configuration file of the resource monitoring terminal to the edge cluster master station for storage, the edge cluster master station can verify the reliability of the resource monitoring terminal during operation, thereby avoiding tampering of the program or configuration file of the resource monitoring terminal during operation, avoiding tampering of the source data, and avoiding data loss of power distributed resources, thereby greatly improving the credibility of power distributed resources in the data processing link.

[0094] In one embodiment, Figure 7 As shown in the figure, another distributed resource monitoring terminal data trust method for power auxiliary services is provided. This method is applied to Figure 1 The resource monitoring terminal in the example is used as an example to illustrate, including the following steps:

[0095] Step S701, collecting raw data of distributed power resources; processing the raw data through the metering chip built into the resource monitoring terminal to obtain terminal source data.

[0096] Step S702: Generate a certificate acquisition request according to the device identification information of the resource monitoring terminal, and send the certificate acquisition request to the edge gateway.

[0097] Step S703, receiving the blockchain certificate returned by the edge gateway based on the certificate acquisition request; the blockchain certificate is obtained by requesting the consensus chain through the edge gateway.

[0098] Step S704: According to the blockchain certificate, the end source data is signed to obtain the signed backend source data.

[0099] Step S705, sending the signed backend source data to the edge gateway.

[0100] Step S706: Send the on-chain request for the signature backend source data to the consensus chain through the edge gateway, so that the consensus chain can perform signature verification processing on the signature backend source data to obtain the signature verification result of the signature backend source data.

[0101] Step S707: If the signature verification result indicates that it is passed, the signature backend source data is uploaded to the chain through the consensus chain.

[0102] The above-mentioned distributed resource monitoring terminal data trust method for power auxiliary services can achieve the following beneficial effects: by signing the end source data of power distributed resources and then uploading them to the chain through the blockchain certificate of the consensus chain where the edge gateway is located, the credibility of the source data in the entire collection and transmission link can be improved, thereby ensuring the accuracy of the user-side settlement business of the virtual power plant composed of power distributed resources, and providing more reliable data trust support for the application of virtual power plants.

[0103] In order to more clearly illustrate the distributed resource monitoring terminal data trust method for power auxiliary services provided by the embodiment of the present disclosure, the above-mentioned distributed resource monitoring terminal data trust method for power auxiliary services is specifically described below with a specific embodiment. Another distributed resource monitoring terminal data trust method for power auxiliary services is provided, which can be applied to Figure 1 The resource monitoring terminal in the system includes data collection link enhancement, data processing link enhancement and data transmission link enhancement, among which:

[0104] The data collection stage is enhanced by accurate data calculation. The resource monitoring terminal has a built-in high-precision dedicated metering chip, which calculates the current, voltage, power and other end source data based on the collected raw data.

[0105] The data processing link realizes data processing link enhancement by sending the version verification code of the resource monitoring program and configuration file to the edge cluster master station for latching. First, after the resource monitoring terminal is powered on for the first time, the program and configuration version verification code V0 is sent to the edge cluster master station, and the edge cluster master station stores V0. After that, the resource monitoring terminal periodically calculates whether the program and configuration version verification code has changed. If it has changed, the changed version verification code V1 is sent to the edge cluster master station. Finally, the edge cluster master station compares V0 and V1. If it is found that V0 and V1 are not equal, it will determine whether there is an application report for on-site upgrade of the program and configuration. If there is no report, the edge cluster master station will issue an alarm for abnormal program and configuration version verification code of the resource monitoring terminal. Otherwise, the edge cluster master station will store V1 as the latest program and configuration version verification code of the resource monitoring terminal.

[0106] The data transmission link realizes the credit enhancement of the data transmission link by introducing blockchain technology. The resource monitoring terminal signs the data by applying for a blockchain certificate, and then transmits the data to the edge gateway to ensure the secure transmission of the data. The resource monitoring terminal sends a certificate request to the edge gateway according to the unique number of the device, and the edge gateway then applies for a certificate from the blockchain system. The blockchain system generates and stores the certificate, and then returns the generated certificate to the edge gateway. The edge gateway finally sends the certificate to the resource monitoring terminal, which is stored locally by the resource monitoring terminal.

[0107] The resource monitoring terminal first signs the data to be uploaded to the chain, and then sends the signed data together with the request upload parameters to the edge gateway. The edge gateway then sends the received data to the blockchain system for an upload request. After receiving the request, the blockchain system first verifies the signature of the data. After the signature verification is passed, the final data is uploaded to the chain, and the result of whether the upload is successful or not is returned to the resource monitoring terminal step by step.

[0108] In this embodiment, by signing the end source data of the distributed power resources with the blockchain certificate of the consensus chain where the edge gateway is located and then uploading it to the chain, the credibility of the source data in the entire collection and transmission link can be improved, thereby ensuring the accuracy of the user-side settlement business of the virtual power plant composed of distributed power resources, and providing more reliable data credibility support for the application of virtual power plants.

[0109] In one embodiment, a distributed resource monitoring terminal data trust system for power auxiliary services is provided, the system comprising: Figure 1The resource monitoring terminal, edge gateway, edge cluster master station and aggregator shown in the figure; the edge gateway is used to isolate the edge cluster master station and the aggregator; the resource monitoring terminal is connected to the edge gateway; the edge cluster master station, the aggregator and the edge gateway form a consensus chain; the aggregator is used to integrate multiple distributed power resources to obtain a virtual power plant; the edge gateway is used to forward the operation information of the virtual power plant to the edge cluster master station; the edge cluster master station is used to generate instructions according to the received operation information and send the instructions to the edge gateway; the edge gateway is also used to forward the adjustment instructions to the resource monitoring terminal; the resource monitoring terminal is used to collect the end source data of the distributed power resources, and forward the end source data to the edge cluster master station through the edge gateway, and at the same time, according to the received instructions, the distributed power resources are adjusted in real time.

[0110] Specifically, aggregators are used to effectively integrate distributed power resources of different types scattered in different spaces to form a virtual centralized power plant, namely a virtual power plant. The integrated virtual power plant will also participate in market competition as a whole, and issue resource regulation demands to each distributed power resource based on the requirements from the edge cluster master station.

[0111] The edge cluster master station is deployed in the dispatching center of the power company. It is responsible for real-time monitoring of the real-time data of various power distributed resources, and issues planned adjustment requirements or real-time adjustment commands according to the operation of the virtual power plant.

[0112] The edge gateway is deployed between the aggregator system and the edge cluster master station. It is responsible for isolating the aggregator's intranet from the power company's dispatching intranet, and uploading and issuing aggregator data, dispatching instructions, etc.

[0113] The resource monitoring terminal is deployed at each power distributed resource. It is responsible for collecting real-time data from each power distributed resource point and performing necessary calculations. It then signs the data and transmits it to the superior. At the same time, it regulates the power distributed resources under its jurisdiction in real time according to the received instructions.

[0114] The edge cluster master, edge gateway and aggregator constitute a decentralized consensus chain network.

[0115] The above-mentioned distributed resource monitoring terminal data trust system for power auxiliary services, through the resource monitoring terminal, signs the end source data of power distributed resources and then uploads it to the chain through the blockchain certificate of the consensus chain where the edge gateway is located. It can improve the credibility of the source data in the entire collection and transmission link, and then ensure the accuracy of the user-side settlement business of the virtual power plant composed of distributed power resources, providing more reliable data trust support for the application of virtual power plants.
