[0054] Those skilled in the art should understand that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention. This part of the embodiments is intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts should still fall within the protection scope of the present invention.

[0055] The data applications of distributed energy storage systems widely cover multiple fields such as energy management, power grid optimization, commercial operation, and safety operation and maintenance. Its core value lies in achieving the maximization of system efficiency through multi-dimensional data fusion and intelligent analysis. These data are currently very valuable data resources. In the case of the increasingly wide application of energy storage systems, there is a need for multi-party data management platforms to analyze and re-develop using the data of energy storage systems.

[0056] Figure 1 It is a schematic diagram of the architecture of a system applying the data transmission method of a distributed energy storage system according to an embodiment of the present invention. The system includes: a data acquisition device 10, multiple transmission target platforms 21, 22, and data application terminals 31, 32. The data acquisition device 10 can obtain data from various devices of the energy storage system in various ways, such as reading the detection results of detection devices (such as current sensors, voltage sensors, power sensors, etc.), collecting data from the data interfaces of devices (such as reading the measurement results of smart meters, reading the operation data of inverters), etc. The data acquisition device 10 can collect devices from power generation devices, power consumption devices, energy storage devices, power metering devices, switch devices, power electronic conversion devices, and other devices.

[0057] The multiple transmission target platforms 21, 22 may include: various data processing platforms such as an energy storage operation management platform, a data analysis platform, a device management platform, and a power grid dispatching platform that may use energy storage data. The data application terminals 31, 32 are connected to the transmission target platforms 21, 22 and serve as terminals for data users to access the transmission target platforms 21, 22, directly using the analysis results of the energy storage data of the transmission target platforms 21, 22. Among them, the number of the multiple transmission target platforms 21, 22 and the data application terminals 31, 32 can be configured according to data needs. The numbers in the figure are only for illustration, and those skilled in the art can set two, three, or even more transmission target platforms 21, 22 and data application terminals 31, 32 according to the description of this embodiment.

[0058] The data acquisition device 10 can use a communication device to send data to the multiple transmission target platforms 21, 22. The communication device can be a communication stick or other similar communication equipment. The communication device can select a communication method according to needs, such as wired / wireless local area network, 5G / 4G and other mobile cellular networks.

[0059] In the current transmission target platforms 21 and 22 (data demand platforms) of the energy storage system, there are some technical barriers between different platforms, and the data types required by each transmission target platform 21 and 22 and the real-time requirements for data are different. For example, for a management platform involved in the regulation of the energy storage system (such as an energy storage operation management platform), it is necessary to obtain data on the operating status in a timely manner. Another example is an analysis platform that involves secondary development of data to assist in the design and research and development of the energy storage system. The required data is statistical data during stable operation, and its real-time requirement for data is relatively low. For another example, for an equipment management platform used for operation analysis and fault diagnosis of energy storage equipment, it is necessary to obtain fault alarm data of the equipment in a timely manner and also obtain various log data generated during equipment operation. For another example, for a grid dispatching platform used to manage the energy exchange between energy storage equipment and the external power grid, it is necessary to obtain dispatching required data from the energy storage system according to dispatching requirements. This data difference makes it difficult for each transmission target platform 21 and 22 to obtain the required data through data interaction between platforms.

[0060] In addition, since there are also competitions and interest conflicts among the management parties to which each transmission target platform 21 and 22 belongs. For example, for the construction party, the user party, and the grid management party of the energy storage system, although they cooperate with each other, their interests have different emphases. Therefore, from the management aspect, there is no requirement for data interconnection among multiple transmission target platforms 21 and 22.

[0061] Therefore, the data transmission method of the distributed energy storage system in this embodiment improves from the data source side of the distributed energy storage system, distributes data as resources to each transmission target platform 21 and 22, and provides strong technical support for the digital transformation and sustainable development of the energy industry.

[0062] Figure 2 It is a schematic diagram of the data transmission method of the distributed energy storage system according to an embodiment of the present invention. Generally, the data transmission method of the distributed energy storage system may include:

[0063] Step S201, obtaining energy storage data generated by the energy storage system. The energy storage data includes various types of data generated by the distributed energy storage system, such as: equipment log data, equipment operating status data, electrical data such as current, voltage, power, and power quality, electricity metering data, environmental data, etc.

[0064] Step S202: Obtain the data requirement configuration information of multiple transmission target platforms. The data requirement configuration information includes the required data content types and the upload priorities corresponding to each data content type. The data requirement configuration information is configured by the transmission target platform according to the data requirements, and it can be in file formats such as structured text configuration (e.g., JSON Schema), industrial protocol specific configuration (e.g., Modbus MAP), and metadata tables. Through the data requirement configuration information, the required data content types and the upload priorities corresponding to each data content type can be determined. Among them, the upload priority is related to the data upload period. The higher the priority, the shorter the upload period, and the stronger the real-time requirement of the data.

[0065] Step S203: Extract the target data required by each transmission target platform from the energy storage data according to the data content type. The data content required by different transmission target platforms is different. Taking the energy storage operation management platform as an example, it may require short-period (e.g., after 1 minute) electrical data (voltage, current, power), and medium-period (e.g., 10 minutes) device operation status data (SOC, module temperature, charge and discharge state); while the data analysis platform requires daily device log data, power measurement data, and environmental data.

[0066] Step S204: Generate a transmission queue for the target data according to its upload priority.

[0067] Step S205: Transmit the data in the transmission queue to multiple transmission target platforms in sequence.

[0068] The method of the above embodiment, for the scenario of a distributed energy storage system transmitting energy storage data to multiple transmission target platforms, extracts the target data required by each transmission target platform according to the data requirement configuration information of the transmission target platform, generates a transmission queue for the target data according to its upload priority; and transmits the data in the transmission queue to multiple transmission target platforms in sequence. The target data extracted from the energy storage data meets the data requirements of the transmission target platform, and by means of the transmission queue, data with different upload priorities can be transmitted to the target platform according to the real-time requirements.

[0069] Figure 3 It is a schematic diagram of the step of generating a transmission queue in the data transmission method of a distributed energy storage system according to an embodiment of the present invention. Figure 4 is Figure 3 A schematic diagram of the data queue generated by the steps shown above. The step of generating a transmission queue for the target data according to the upload priority in the above step S204 may include:

[0070] Step S301, determine the upload cycle of the data with the highest priority for multiple transmission target platforms according to the upload priority. The highest priority means that the data has the highest real-time requirement, that is, the data needs to be transmitted to the transmission target platform with faster data transmission after it is generated.

[0071] Step S302, insert a priority transmission block at a specified position of the transmission queue according to the upload cycle of the data with the highest priority, and the priority transmission block is generated by the data with the highest priority. The data with the highest priority may include: status data participating in the real-time operation and regulation of the energy storage system, and warning data containing alarm information. These data can be used to formulate a regulation plan for the distributed energy storage system and realize active management of its own resources, such as adjusting the operating mode of power generation equipment, power consumption equipment, energy storage equipment, and switching equipment. Step S303, search for blank positions in the transmission queue step by step according to the upload priority, and insert ordinary transmission blocks corresponding to the upload priority in the blank positions. Ordinary transmission blocks are generated by data with lower priority. Ordinary transmission blocks may include multiple levels.

[0072] Taking data transmission to two transmission target platforms A and B as an example, the key data has the highest priority. In the transmission queue, the priority transmission blocks of the key data A1 and B1 are first inserted into the transmission queue, and then the second-level ordinary transmission blocks with the next priority (such as regular data, recorded as A2 and B2) are determined, and then the ordinary transmission blocks of the regular data A2 and B2 are inserted between the priority transmission blocks of A1 and B1; if there are also level 3 ordinary transmission blocks (such as log data, recorded as A3 and B3), the ordinary transmission blocks of log data A3 and B3 are inserted into the remaining free areas of the transmission queue. By analogy, the method of this embodiment can arrange the queues of priority transmission blocks and multi-level ordinary transmission blocks. The size of each data block in the above transmission queue and the idle interval between the data blocks can be configured according to the data transmission rate of the transmission device to ensure that each data block can complete the transmission within the set time and complete the preparation for the transmission of the next transmission block within the interval.

[0073] Figure 5 1 is a schematic diagram of the steps of processing a transmission queue in a data transmission method of a distributed energy storage system according to an embodiment of the present invention. After generating the transmission queue, the following steps may also be included:

[0074] Step S501: Add transmission information to the transport blocks in the transmission queue. The transmission information includes: the transmission address corresponding to the target platform, the data identifier, and the time generation information. The transmission address corresponding to the target platform is used to indicate the transmission target address of the transport block. When using the network transmission mode, the transmission target address of the transport block can be an IP address. The data identifier and the time generation information are used to assist the target platform in data restoration. The data identifier is unique and can be an incrementing sequence to indicate the order of the data. The time generation information is used to indicate the generation time of the data. Through the data identifier and the time generation information, the target platform can restore the received data.

[0075] Step S502: Perform serial data transmission according to the transmission address of the corresponding target platform of the transport block using the Modbus TCP transmission protocol.

[0076] When uploading existing energy storage data to the cloud platform, the MQTT (Message Queuing Telemetry Transport) protocol is generally used. Although MQTT has the characteristics of lightweight, high reliability, and flexible architecture, it consumes the computing power of the communication device and is not suitable for the characteristics of distributed energy storage systems. Especially when sending data to multiple platforms, a large computing power chip is required for support. To reduce the hardware cost, the method of this embodiment can unify the Modbus protocol and transmit data to multiple platforms in a logic similar to virtual transparent transmission. After the communication device collects the device data, only fine-tuning of the transmission protocol is performed, that is, converting from Modbus-RTU to Modbus TCP, and only the IP address is changed between multiple platforms, greatly reducing the computing work of the communication device.

[0077] In some embodiments, this method can also cancel the TLS encryption process and use the software encryption method of the target platform, breaking through the limitation that TLS encryption can only be adapted to one communication module. Decoding and compilation are performed on the target platform. Thereby further reducing the computing pressure of the communication device and releasing all computing power resources for data transmission.

[0078] Figure 6 It is a schematic diagram of the steps for obtaining energy storage data in the data transmission method of a distributed energy storage system according to an embodiment of the present invention. The above step S201 for obtaining the energy storage data generated by the energy storage system may include:

[0079] Step S601: Read the original data generated by each device in the energy storage system using a pre-configured data interface.

[0080] Step S602: Preprocess the original data and generate additional information based on the data source, reading time, and content description information of the original data. During the preprocessing process, data filtering, standardization processing, etc. can also be performed. Filtering out abnormal data through the above data filtering rules can improve the data quality of the qualified energy storage data to be processed. Standardizing the qualified data can form a unified, consistent, and high-quality data set. For example, the data dimension, protocol, encoding method, etc. can be unified. The conversion process can convert the data into a unified format and structure, including data type conversion, data normalization, data aggregation, etc.

[0081] Step S603: Combine the processed original data and the additional information into energy storage data. The additional information helps to enhance the interpretability of the data and reduce the difficulty of restoring and parsing the data on the transmission target platform.

[0082] The above step S202 of extracting the target data required by each transmission target platform from the energy storage data according to the data content type may include:

[0083] Step S604: Match the additional information with the data requirement configuration information;

[0084] Step S605: Classify the matched energy storage data according to the corresponding upload priorities to obtain the target data. For example, the classification process may include: determining the upload priority corresponding to the energy storage data; finding the cache policy corresponding to the determined upload priority; storing the energy storage data in the corresponding data storage area according to the determined cache policy. For example, a hierarchical cache structure can be designed in the data acquisition device. For example, the first cache level L1 is set using a high-speed SRAM storage medium to store critical data; the second cache level L2 is set using a DRAM storage medium to store regular data; the third cache level L3 is set using an SSD storage medium to store log data. Different levels of energy storage data adopt different caching methods, and select to clear or perform other full / partial storage to disk after transmission.
