[0030] Embodiment 1

[0031] Figure 1 This is a flowchart of a synchronous update method for multi-source heterogeneous data applied to a virtual power plant provided in the first embodiment of the present invention. This embodiment can be applied to the processing of multi-source heterogeneous adjustable resource data of a virtual power plant and the inconvenience of data application. The method can be executed by a synchronous update device for multi-source heterogeneous data applied to a virtual power plant. The device can be implemented in the form of hardware and / or software, and the device can be configured in a computer device. Figure 1 As shown, the method includes:

[0032] S110. Collect the data to be collected corresponding to the adjustable resource equipment of the virtual power plant.

[0033] The adjustable resource equipment includes at least one of a photovoltaic system, an energy storage system, a charging pile, a heating system, a cooling system, and a distribution switch bay; the data to be collected may be data related to the adjustable resource equipment, and the data to be collected may include operating status information of the adjustable resource equipment, such as power generation, power output, equipment status, etc. Or, information such as energy storage level, charge and discharge status, temperature, etc. Or, information such as energy consumption data and load conditions may be collected.

[0034] It can be understood that a virtual power plant is a power coordination management system that uses information communication technology and software systems to achieve the aggregation and coordinated optimization of distributed energy resources such as distributed power sources, energy storage systems, and controllable loads, so as to participate in the power market and power grid operation as a special power plant. A virtual power plant does not have the physical form of a physical power plant (such as a thermal power plant), but is a management model or a system.

[0035] In order to aggregate and coordinate the optimization of distributed energy resources, the data to be collected of each adjustable resource equipment corresponding to the virtual power plant can be obtained, and the control and optimization of resources can be achieved based on the data to be collected.

[0036] In an embodiment of the present invention, collecting the data to be collected corresponding to the adjustable resource devices of the virtual power plant may include: according to each of the communication protocol types, performing access collection configuration for each of the adjustable resource devices to configure preset configuration information; after completing the access collection configuration, calling the data collection module corresponding to the communication protocol type to collect the data to be collected corresponding to each of the adjustable resource devices based on the data collection module.

[0037] The data to be collected includes a response message corresponding to the adjustable resource, and the communication protocol type includes at least one of IEC104, MODBUS-RTU, MODBUS-TCP, MQTT and HTTP. The communication protocol type and typical data format of the communication protocol of the adjustable resource equipment of the virtual power plant are shown in Table 1 and Table 2.

[0038] Table 1

[0039]

[0040]

[0041] Table 2

[0042]

[0043]

[0044] Specifically, when collecting the data to be collected corresponding to the adjustable resource devices of the virtual power plant, access collection configuration can be performed for each adjustable resource device according to each communication protocol type, and corresponding preset configuration information can be configured for each adjustable resource device to ensure that communication with the adjustable resource device can be carried out and the corresponding data to be collected can be obtained.

[0045] The preset configuration information may be pre-configured information, for example, the preset configuration information includes communication parameters and measurement point configuration information. After completing the access collection configuration, the data collection module corresponding to the communication protocol type may be called, and the data to be collected corresponding to each adjustable resource device may be collected based on the data collection module. The data to be collected may be the response message fed back by the adjustable resource after the data collection module sends the data collection request. Figure 2 The figure shows a flow chart of collecting data to be collected provided in the first embodiment of the present invention.

[0046] S120. According to the communication protocol type of the adjustable resource device, convert the data to be collected into data to be processed in a preset communication format.

[0047] The preset communication format may be understood as a unified and standardized data communication format, and the data to be processed may be data obtained after conversion of the collected data.

[0048] It is understandable that the multi-source heterogeneity of adjustable resource data often causes great inconvenience to the processing and use of data. In order to solve the problem of multi-source heterogeneity of adjustable resource data and inconvenience in data application, the data to be collected can be converted into data to be processed in a preset communication format.

[0049] Specifically, a unified data communication format can be designed based on the protocol structure style and data characteristics of each protocol, and the collected data can be standardized into a unified data communication format through a protocol adapter and saved in a local data temporary storage area. The preset communication format is shown in Table 3:

[0050] Table 3

[0051]

[0052]

[0053] In an optional implementation, according to the communication protocol type of the adjustable resource device, converting the data to be collected into data to be processed in a preset communication format includes:

[0054] When the communication protocol type is MODBUS-RTU or MODBUS-TCP, the first register address of the request message corresponding to the data to be collected is recorded; when a response message is received, the associated register address of each measuring point corresponding to the response message is determined and calculated according to the first register address; the measuring point information of each measuring point is queried according to the associated register address, and the data to be processed in the preset communication format is generated according to the measuring point information and the return time of the response message.

[0055] Specifically, when sending a request message to an adjustable resource, the register address in the message can be recorded. The address is used to identify the storage location of data in the MODBUS protocol. Then, based on the register address in the request message, the register address associated with each measuring point value in the response message is calculated. With the address of the associated register, the measuring point details corresponding to the address can be queried, and the corresponding measuring point value, i.e., the measuring point information, can be accessed. Then, combined with the return time of the response message and the measuring point configuration information, the data to be processed in a unified preset communication format is generated.

[0056] For example, Table 4 is an example of a MODBUS request message and a response message, and Table 5 is an example of the returned data after parsing:

[0057] Table 4

[0058]

[0059] Table 5

[0060] Serial number Register Address Parsing Values 1 20 20.5 2 22 5.5 3 24 219.9 4 26 221.4 5 28 220.3 6 30 3 7 31-47 0 24 48 3 25 49-59 0

[0061] Then, according to the recorded register address and measurement point configuration information, the data to be processed in a unified preset communication format is generated, wherein the data to be processed corresponding to the measurement point of register address 20 can be expressed as:

[0062]

[0063] In an optional implementation, converting the data to be collected into data to be processed in a preset communication format according to the communication protocol type of the data to be collected includes:

[0064] When the communication protocol type is IEC104, the measuring point data, measuring point time, and associated point number of the measuring point are determined according to the response message and the preset configuration information; after the associated information of the measuring point is queried through the associated point number, the data to be processed in the preset communication format is generated based on the measuring point data, the measuring point time, and the associated information.

[0065] Specifically, when receiving the response message of the IEC104 protocol, the measurement point data of the measurement point, such as the specific measurement value, acquisition time, and the point number associated with the measurement point, can be extracted from the response message. In the IEC104 protocol, the point number is usually used to uniquely identify a specific measurement point. Through the point number, other information of the measurement point associated with the point number can be queried in the measurement point configuration information, such as the name of the measurement point, type (such as telemetry, telesignaling, etc.), unit, etc.

[0066] Finally, the extracted and queried information is standardized according to the preset communication format to obtain the data to be processed, which ensures that data from different sources and in different formats can be processed and analyzed in a unified manner.

[0067] Exemplarily, the response message (response message) of the IEC104 protocol is processed. Table 6 is an example of an IEC104 response message:

[0068] The returned data of the response message parsed in Table 6 is shown in Table 7:

[0069] Serial number Register Address Parsing Values 1 4059H 0 2 405AH 0 3 405BH 0 4 405CH 0 5 405DH 0 6 405EH 0 7 405FH 0 8 4060H 0 9 4061H 0 10 4062H 0

[0070] The recorded register address and measurement point configuration information are formatted into the preset communication format shown in Table 3. For example, the measurement point at register address 4059H can be represented as:

[0071] {

[0072] "attribute id":16380,

[0073] "Attribute name":"Measurement point 1",

[0074] "Measurement point type":"Telemetry",

[0075] "Measurement point value": 0,

[0076] "Time":1721370455465,

[0077] "Storage Flag":"true",

[0078] "Data status indicator":""

[0079] }

[0080] In an optional implementation, converting the data to be collected into data to be processed in a preset communication format according to the communication protocol type of the data to be collected includes:

[0081] When the communication protocol type is MQTT, the global ID of the measuring point is obtained according to the response message and the preset configuration information; the associated information of the measuring point is queried through the global ID association, and the data to be processed in the preset communication format is generated based on the data field, the acquisition time field and the associated information of the response message.

[0082] Specifically, the global ID is usually used to uniquely identify a measurement point. The global ID can be obtained by parsing the MQTT response message. By querying the measurement point configuration information based on the global ID, the associated information of the measurement point can be determined, such as the measurement point name, data type, etc. Combined with the data and time fields of the response message, according to the preset communication format, the data to be processed is combined.

[0083] S130, pre-processing the data to be processed to determine a data status label corresponding to the data to be processed, determining the data to be fused based on the data status label, and storing the data to be fused in a target database.

[0084] It should also be noted that after the data to be processed is stored in the local data temporary storage area, it will exist as temporary data. Temporary data includes dirty data and inconsistent data. The dirty data in the collection process mainly refers to data that exceeds the reasonable range of the collection value, empty data, and meaningless register data collected during the communication process.

[0085] Therefore, the data to be processed can be preprocessed, the data status label corresponding to the data to be processed can be determined, the data to be processed can be labeled as the data to be fused, and then pushed to the internal bus. When the target database needs to obtain and store the data to be fused, the data to be fused on the internal bus can be obtained. After being stored in the target database, it is convenient to integrate and utilize the data to be fused as the data basis for virtual power plant control optimization.

[0086] The technical solution of the embodiment of the present invention is applied to a virtual power plant, and the solution includes: collecting the data to be collected corresponding to the adjustable resource equipment of the virtual power plant, wherein the adjustable resource equipment includes at least one of a photovoltaic system, an energy storage system, a charging pile, a heating system, a cooling system, and a distribution switch interval; according to the communication protocol type of the adjustable resource equipment, converting the data to be collected into data to be processed in a preset communication format; preprocessing the data to be processed to determine the data status label corresponding to the data to be processed, determining the data to be fused based on the data status label, and storing the data to be fused in a target database. By standardizing the multi-source heterogeneous data to be collected according to the differences in the adjustable resource equipment and protocols in the virtual power plant scenario, the problems of multi-source heterogeneity and inconvenience in data application of the adjustable resource data are solved, and after preprocessing and storage, it is ready for the fusion of the adjustable resource data.

Based on the above embodiment, this embodiment further optimizes the process of adding data status tags to the data to be processed. Figure 3 As shown, the method includes:

[0091] S230: Process the data to be processed according to the numerical range and data consistency corresponding to the data to be processed, and add the data status label to the data to be processed.

[0093] Among them, the first type refers to type 1, the second type refers to type 2, the third type refers to type 3, and the zeroth type refers to type 0.

[0094] Specifically, for the processing of dirty data: if the collected data is data beyond the normal value range, the data is marked with a data status label of type 1 and pushed to the internal bus; if the collected data is empty data, the data is marked with a data status label of type 2 and pushed to the internal bus; if the collected data is meaningless register data, the data is marked with a data status label of type 3 and pushed to the internal bus or directly discarded; otherwise, the collected data is marked with a data status label of type 0 and pushed to the internal bus, indicating that the data is normal.

[0095] In an embodiment of the present invention, processing the data to be processed and adding the data status label to the data to be processed may also include: if the data type of the data to be processed is inconsistent with the preset data type, performing type conversion on the data to be processed and marking the data to be processed with a data status label of the zeroth type; if there is coefficient information in the data to be processed, processing the data to be processed based on the coefficient information and marking the data to be processed with a data status label of the zeroth type.

[0096] Specifically, for the processing of inconsistent data: if the data type of the data to be processed is inconsistent with the preset data type, the data needs to be converted, usually converted to a floating point number and marked with a data status label of type 0, and then pushed to the internal bus; if the data to be processed contains coefficient information, the data to be processed needs to be multiplied by the coefficient, marked with a data status label of type 0, and then pushed to the internal bus.

[0097] like Figure 4 , which is a flow chart of data preprocessing provided in Embodiment 2 of the present invention.

[0099] S250: Push the data to be merged to the internal bus, and store the data to be merged in the target database according to a call request of the storage interface of the target database.

[0100] Specifically, storing the data to be merged into the target database includes real-time database update and historical database update. Real-time database update: take out data with data status 0 and status 1 from the internal bus and save them to the real-time database. Take out data with data status 2 from the internal bus, record the exception, and decide whether to update the real-time database according to the business scenario.

[0101] History database update: If scheduled update is configured, call the real-time database interface to complete the periodic insertion of the history database; if change update is configured, subscribe to the bus data to implement the change update.
