[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] The Internet of Things data interaction method for a virtual power plant provided in an embodiment of the present invention is executed by a computer device, and accordingly, the Internet of Things data interaction system for a virtual power plant runs in the computer device.

[0024] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution subject may be an IoT data interaction system of a virtual power plant. According to different requirements, the order of the steps in the flowchart may be changed, and some may be omitted.

[0025] like Figure 1 As shown, the method includes: Step 110, deploying multiple communication components at the external interface of the virtual power plant, wherein the communication components correspond to the transmission protocol; Step 120, construct corresponding queues for multiple communication components respectively, and establish a subscription relationship between a processing component and the queue, wherein the processing component includes a customized data processing strategy; Step 130, obtaining attribute information of the IoT devices, and grouping the IoT devices based on the attribute information to obtain multiple device groups; Step 140: Establish a mapping relationship between the device group and the communication component.

[0026] To facilitate understanding of the present invention, the Internet of Things data interaction method for a virtual power plant provided by the present invention is further described below based on the principle of the Internet of Things data interaction method for a virtual power plant of the present invention and in combination with the process of managing the Internet of Things data interaction of a virtual power plant in an embodiment.

[0027] Specifically, the IoT data interaction methods of virtual power plants include: S1. Deploy multiple communication components at the external interface of the virtual power plant, and the communication components correspond to the transmission protocol.

[0028] These communication components are carefully selected to cover a wide range of transmission protocols, including but not limited to MQTT, HTTP, WebSocket, etc., to ensure that the virtual power plant can flexibly adapt to and integrate IoT device data from different sources and following different standards. This deployment strategy not only enhances the compatibility and scalability of the virtual power plant, but also lays a solid foundation for subsequent data processing and interaction.

[0029] S2. Build corresponding queues for multiple communication components respectively, and establish a subscription relationship between a processing component and the queues, wherein the processing component includes a customized data processing strategy.

[0030] Parse the input data format of the processing component and obtain the transmission protocol corresponding to the input data format; establish a subscription relationship between the processing component and the queue of the communication component based on the corresponding relationship between the processing component and the transmission protocol.

[0031] In order to efficiently manage the data flows from different communication components, a dedicated queue system was independently built for each communication component. These queues serve as a bridge for data buffering, effectively balancing the difference between the data transmission rate and processing power. Next, we deeply analyzed the input data format requirements of the processing components and identified the transmission protocols that match each data format. Based on this correspondence, we established an intelligent subscription relationship between the processing component and the corresponding communication component queue. The processing component has built-in user-customizable data processing strategies that can automatically pull data from the subscribed queues and perform operations such as cleaning, conversion, and analysis to ensure that the data quality meets business needs.

[0032] S3. Acquire attribute information of IoT devices, and group the IoT devices based on the attribute information to obtain multiple device groups.

[0033] Obtain attribute information of the IoT device, wherein the attribute information includes device type, output data format and corresponding transmission protocol, and output data items; and classify IoT devices with the same attribute information into the same device group.

[0034] In order to optimize the management and scheduling of IoT devices, a device grouping strategy based on attribute information is proposed. First, the attribute information of the device is comprehensively collected through the IoT platform, including but not limited to the device type, the format of the output data, the corresponding transmission protocol, and the specific output data items. Subsequently, these attribute information are used as the basis for grouping, and IoT devices with the same or similar attributes are divided into the same device group. This grouping method not only simplifies the device management process, but also facilitates the subsequent targeted data collection and processing according to the characteristics of the device group.

[0035] S4. Establish a mapping relationship between the device group and the communication component.

[0036] Based on the format of the output data of the IoT devices in the device group and the corresponding transmission protocol, a matching communication component is assigned to the device group; the data interaction volume is evaluated based on the number and type of IoT devices in the device group corresponding to the communication component; and IO resources are allocated to each communication component according to the proportion of data interaction volume of each communication component.

[0037] When establishing the mapping relationship between the device group and the communication component, the matching degree between the output data characteristics of the device group and the communication component is fully considered. Specifically, the most suitable communication component is assigned to each device group according to the output data format and the corresponding transmission protocol of the IoT devices in the device group. In addition, in order to further optimize resource allocation, the number of IoT devices, device types, and expected data interaction volume of each communication component corresponding to the device group are also evaluated. Based on these evaluation results, corresponding IO resources are allocated to them according to the proportion of data interaction of each communication component to ensure the data interaction efficiency and stability of the entire virtual power plant system.

[0038] In some embodiments, the virtual power plant IoT data interaction system may include multiple functional modules composed of computer program segments. The computer programs of each program segment in the virtual power plant IoT data interaction system may be stored in a memory of a computer device and executed by at least one processor to perform (see Figure 1 Description) The function of IoT data interaction of virtual power plants.
