[0039] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0040] Energy storage systems are essential basic measures for the development of microgrids, island power grids, distributed power generation systems, and new energy vehicle fast charging technologies. The use of energy storage systems in power systems has achieved demand-side management, peak shaving and valley filling, load smoothing, and rapid adjustment of grid frequency, improving grid operation stability and reliability, and reducing the impact of photovoltaic and wind power and other new energy power generation systems with large instantaneous changes on the grid. In order to facilitate outdoor layout, simplify the installation and commissioning process, and reduce deployment time and cost investment, energy storage systems require energy storage cabinets that integrate high-performance inverters, large-capacity batteries, data acquisition devices, etc. in one cabinet. With the development of energy storage technology, multiple energy storage cabinets can be connected in parallel to improve the energy storage efficiency of the energy storage system, thereby meeting various energy storage needs from small enterprises to large industrial parks.

[0041] In the related art, when performing the parallel operation of energy storage cabinets, the common method is to add and identify the equipment according to the equipment type in each energy storage cabinet, and then manually click to match. The adding steps in the related method are cumbersome, and the manual operation error rate is high, which leads to the problems of low efficiency of parallel deployment of multiple energy storage cabinets and high subsequent maintenance costs.

[0042] In order to solve the above problems, an embodiment of the present invention provides a device identification and matching method, which is applied to an energy management system; Figure 1 As shown, the device identification and matching method mainly includes:

[0043] Step S101, in response to the parallel connection of multiple energy storage cabinets, configure IP addresses for devices in the multiple energy storage cabinets based on the energy management system; wherein the devices in the energy storage cabinets include inverters, energy storage batteries and data acquisition devices.

[0044] Through the above settings, the energy management system automatically configures IP addresses for the devices to be identified and matched. Subsequently, communication is established with the devices based on the IP addresses, which can quickly and accurately obtain device information and complete device identification. This reduces the workload of manual identification and the errors in manual operations, improves the operating efficiency and stability of the system, and helps to improve identification efficiency and the degree of automation.

[0045] In some of the embodiments, the step of configuring IP (Internet Protocol, a protocol for interconnecting networks) addresses for devices in multiple energy storage cabinets based on the energy management system in response to the parallel connection of multiple energy storage cabinets includes: in response to the parallel connection of multiple energy storage cabinets, the energy management system establishes connections with the devices in the multiple energy storage cabinets; and according to the number of devices established with the connection, configuring IP addresses for the multiple devices through the dynamic host configuration protocol.

[0046] The above provides a specific implementation method for configuring IP addresses in the Energy Management System (EMS). When multiple energy storage cabinets are connected in parallel, the Energy Management System determines which devices are connected to the network by detecting whether the devices are connected to the specified physical port, and automatically configures IP addresses for the connected devices through DHCP (Dynamic Host Configuration Protocol). Among them, the DHCP protocol can effectively manage the IP address pool, avoid address conflicts, and ensure that each device can obtain an available IP address; the automatic configuration of IP addresses reduces the need for manual intervention, and improves the configuration rate and accuracy while improving the degree of automation.

[0047] Furthermore, as the number of energy storage cabinets changes, DHCP can easily adapt and automatically adjust address allocation, simplifying the process of system expansion and maintenance. Dynamic address allocation can handle the addition or removal of devices more flexibly and reduce system failures caused by improper manual configuration. That is, by using the DHCP protocol to automatically assign IP addresses to devices in the energy storage cabinet, the system automation level can be effectively improved, configuration errors can be reduced, the system maintenance process can be simplified, and the communication capabilities between devices and the overall reliability of the system can be enhanced.

[0048] According to an embodiment of the present invention, Figure 2 As shown, when multiple energy storage cabinets are connected in parallel, each device in the energy storage cabinet ( Figure 2 The inverter, energy storage battery, and data acquisition device in the system are all connected to the energy management system EMS, and then the EMS configures an IP address for each device through DHCP, so that the EMS can subsequently establish a TCP (Transmission Control Protocol) communication connection with each device based on the configured IP address to obtain device information.

[0049] In some of the embodiments, before the step of configuring IP addresses for devices in multiple energy storage cabinets based on the energy management system, the method further includes: in any energy storage cabinet, establishing a communication connection with an associated energy storage battery through an inverter to obtain and record a serial number corresponding to the associated energy storage battery; establishing a communication connection between the energy storage battery and an associated data acquisition device to obtain and record the serial number of the associated data acquisition device; wherein the devices in the energy storage cabinet communicate based on the MODUBUS TCP protocol.

[0050] Through the above settings, in the energy storage cabinet, the inverter locally records the serial number of the associated energy storage battery, and the energy storage battery records the serial number of the associated data acquisition device, providing data support for subsequent device matching. Subsequently, based on the serial number of the associated device, device matching can be achieved quickly and accurately.

[0051] Among them, MODBUS TCP used in the embodiment of the present invention is one of the standard protocols widely used in the field of industrial automation. It provides a stable and reliable communication mechanism to ensure accurate data transmission. Using it as a standard communication protocol ensures compatibility between different devices and facilitates communication and data exchange between devices. Obtaining key information such as the serial number before configuring the IP address can simplify the subsequent device matching process and improve the accuracy and efficiency of matching. And by obtaining information such as the serial number at an early stage, the device information can be pre-recorded in the system, which is convenient for rapid search of device information during later maintenance and system expansion, simplifying the device matching process, reducing configuration errors, and enhancing the maintainability and scalability of the system.

[0052] Step S102, establishing communication connections with multiple devices respectively according to the IP addresses to obtain device information corresponding to the multiple devices to achieve device identification; wherein the device information includes the serial number of the current device and the serial number of the associated device corresponding to the current device.

[0053] Through the above settings, by obtaining key information such as serial numbers, the system can accurately identify each device and determine the relationship between them, thereby achieving matching between devices. Automatically obtaining device information reduces the need for manual intervention, improves the automation level of device identification and matching, and reduces the error rate introduced by manual operation. At the same time, through information such as serial numbers, the system can more easily track and locate devices, which helps to quickly diagnose and maintain when there is a problem with the device.

[0054] In some of the embodiments, after the step of obtaining device information corresponding to multiple devices, the method further includes: determining whether the device information corresponding to the target device is complete; if incomplete, generating a communication line check instruction between the target device and the associated device, so that the operator can check according to the communication line check instruction; after the communication line check is completed, obtaining the device information corresponding to the target device again through the energy management system.

[0055] The above steps provide a redundant mechanism in the process of obtaining device information. By checking the integrity of device information, the data stored in the system is ensured to be accurate. Communication line problems can also be discovered and handled in a timely manner to reduce equipment failures caused by poor communication lines. Ensuring the integrity of device information and the normal working state of communication lines helps maintain the stable operation of the system.

[0056] Through the above settings, by adding steps to determine the integrity of device information and generating communication line check instructions when necessary, the data accuracy and system stability of the device management system can be effectively improved, and maintenance costs can be reduced, ultimately improving user experience.

[0057] In some of the embodiments, if there are multiple energy storage batteries in the energy storage cabinet, the energy storage battery with the device number recorded in the inverter in the energy storage cabinet is used as the master energy storage battery, and the rest are slave energy storage batteries; the above method also includes: the master energy storage battery establishes a communication connection with each slave energy storage battery respectively to obtain and record the serial number of the associated slave energy storage battery; and the device matching table is updated according to the serial number of the master energy storage battery and the serial number of the associated slave energy storage battery.

[0058] It is understandable that all energy storage batteries can also be associated in the inverter, and the serial numbers corresponding to all energy storage batteries corresponding to the inverter can be recorded to determine the device matching table. Through the above settings, by clarifying the master-slave relationship of the energy storage batteries, the management and monitoring process of the energy storage system can be simplified, so that the system can operate more efficiently, which is helpful for the subsequent increase or decrease of the number of batteries in the energy storage cabinet and the replacement of faulty batteries, thereby improving the maintenance efficiency of the device matching table. At the same time, the clear master-slave relationship of the energy storage battery helps to quickly locate the fault point, thereby improving the maintainability and fault recovery speed of the system. When the energy storage system needs to be expanded, the architecture based on the existing master-slave relationship can more easily connect new energy storage battery units, simplifying the expansion process.

[0059] Step S103: Generate a device matching table according to the device information to implement device matching operations in the same energy storage cabinet.

[0060] Through the above settings, the device matching table is generated directly based on the device information obtained automatically, which can ensure that all devices can be accurately identified and matched with the correct components, thereby reducing errors caused by manual operation and improving the reliability and stability of the overall system.

[0061] According to an embodiment of the present invention, Figure 2 As shown, the EMS establishes a TCP communication connection with each device based on the configured IP address, and after obtaining the device information, directly generates a device matching table according to the device serial number indicated in the device information and the serial number of the associated device.

[0062] In some of the embodiments, if an energy storage battery fails, after the failed battery is replaced, a communication connection is established between the inverter and the replacement battery and the serial number of the replacement battery is obtained, and the replacement battery establishes a communication connection with a data acquisition device in the same energy storage cabinet and the serial number of the data acquisition device is obtained; the above method also includes: receiving device information update data sent by the inverter, and updating the device matching table according to the device information update data.

[0063] Based on the above settings, a device matching table update strategy is provided in the event of a storage battery failure during the operation of multiple energy storage cabinets connected in parallel. This strategy can update the device matching table immediately after the battery is replaced to ensure the real-time accuracy of the system status; and through the automated serial number acquisition and matching table update mechanism, the error rate caused by manual operation is reduced, thereby significantly improving the maintenance efficiency and operation stability of the energy storage system, while reducing the potential risks caused by equipment replacement.

[0064] In some of the embodiments, the method further includes: receiving the collected data sent by the data collection device based on the energy management system, determining the collection object device according to the collected data and the device matching table, and generating a maintenance instruction or a control instruction.

[0065] By automatically analyzing the collected data, intelligent monitoring and management of equipment is achieved. Specifically, by accurately identifying equipment that needs maintenance, unnecessary maintenance operations are avoided; by quickly generating control instructions, necessary adjustments or controls are made to the equipment to optimize energy use. In addition, the links of manual decision-making are reduced, the risk of misjudgment is reduced, the intelligence level of the energy management system is improved, the efficient operation of equipment is ensured, and costs are reduced and energy utilization is improved by reducing unnecessary maintenance work and improving control accuracy.

[0066] The above-mentioned device identification and matching method provided in the embodiment of the present invention adopts the method of configuring IP addresses for devices in multiple energy storage cabinets based on the energy management system in response to the parallel connection of multiple energy storage cabinets; wherein the devices in the energy storage cabinet include inverters, energy storage batteries and data acquisition devices; establishing communication connections with multiple devices respectively according to the IP addresses to obtain device information corresponding to the multiple devices to realize device identification; wherein the device information includes the serial number of the current device and the serial number of the associated device corresponding to the current device; generating a device matching table according to the device information to realize the technical means of device matching operation in the same energy storage cabinet, overcoming the problems of low automation, high labor cost, high identification and matching errors in the related technology for device identification and device matching operations, thereby resulting in low parallel deployment efficiency and high subsequent maintenance cost of multiple energy storage cabinets, realizing the rapid realization of device identification by configuring IP addresses to establish connections to obtain device information, and then generating a device matching table according to the serial number of the current device and the serial number of the associated device included in the device information to realize device matching, thereby improving the automation of device identification and matching, reducing labor cost, and improving the accuracy of identification and matching, thereby improving the parallel deployment efficiency of multiple energy storage cabinets and reducing the technical effect of subsequent maintenance cost.

[0067] Based on the above-mentioned device identification and matching method provided by the embodiment of the present invention, the embodiment of the present invention also provides a device identification and matching device, which is arranged in an energy management system, such as Figure 3 As shown, the device identification and matching apparatus 300 includes:

[0068] The address allocation module 301 is used to configure IP addresses for devices in multiple energy storage cabinets based on the energy management system in response to the parallel connection of multiple energy storage cabinets; wherein the devices in the energy storage cabinets include inverters, energy storage batteries and data acquisition devices.

[0069] Through the above settings, the energy management system automatically configures IP addresses for the devices to be identified and matched. Subsequently, communication is established with the devices based on the IP addresses, which can quickly and accurately obtain device information and complete device identification. This reduces the workload of manual identification and the errors in manual operations, improves the operating efficiency and stability of the system, and helps to improve identification efficiency and the degree of automation.

[0070] In some of the embodiments, the address allocation module 301 is also used to establish connections between the energy management system and the devices in the multiple energy storage cabinets in response to the parallel connection of multiple energy storage cabinets; and configure IP addresses for the multiple devices through the dynamic host configuration protocol according to the number of devices established.

[0071] When multiple energy storage cabinets are connected in parallel, the energy management system determines which devices are connected to the network by detecting whether the devices are connected to the designated physical port, and automatically configures IP addresses for the connected devices through DHCP (Dynamic Host Configuration Protocol). Among them, the DHCP protocol can effectively manage the IP address pool, avoid address conflicts, and ensure that each device can obtain an available IP address; the automatic configuration of IP addresses reduces the need for manual intervention, and improves the configuration rate and accuracy while improving the degree of automation.

[0072] In some of the embodiments, before the step of configuring IP addresses for devices in multiple energy storage cabinets based on the energy management system, in any energy storage cabinet, the inverter establishes a communication connection with the associated energy storage battery to obtain and record the serial number corresponding to the associated energy storage battery; the energy storage battery establishes a communication connection with the associated data acquisition device to obtain and record the serial number of the associated data acquisition device; wherein the devices in the energy storage cabinet communicate based on the MODUBUS TCP protocol.

[0075] Through the above settings, by obtaining key information such as serial numbers, the system can accurately identify each device and determine the relationship between them, thereby achieving matching between devices. Automatically obtaining device information reduces the need for manual intervention, improves the automation level of device identification and matching, and reduces the error rate introduced by manual operation. At the same time, through information such as serial numbers, the system can more easily track and locate devices, which helps to quickly diagnose and maintain when there is a problem with the device.

[0076] In some of the embodiments, the device identification and matching apparatus 300 further includes a device information verification module. After the step of obtaining device information corresponding to a plurality of devices, the device information verification module is used to: determine whether the device information corresponding to the target device is complete; if incomplete, generate a communication line check instruction between the target device and the associated device, so that the operator can perform a check according to the communication line check instruction; after the communication line check is completed, obtain the device information corresponding to the target device again through the energy management system.

[0077] Through the above settings, by adding steps to determine the integrity of device information and generating communication line check instructions when necessary, the data accuracy and system stability of the device management system can be effectively improved, and maintenance costs can be reduced, ultimately improving user experience.

[0078] The matching module 303 is used to generate a device matching table according to the device information to implement device matching operations in the same energy storage cabinet.

[0079] Through the above settings, the device matching table is generated directly based on the device information obtained automatically, which can ensure that all devices can be accurately identified and matched with the correct components, thereby reducing errors caused by manual operation and improving the reliability and stability of the overall system.

[0080] In some of the embodiments, if an energy storage battery fails, after the failed battery is replaced, a communication connection is established between the inverter and the replacement battery and the serial number of the replacement battery is obtained, and the replacement battery establishes a communication connection with a data acquisition device in the same energy storage cabinet and the serial number of the data acquisition device is obtained; the above-mentioned device identification and matching device 300 also includes a device matching table update module, which is used to: receive device information update data sent by the inverter, and update the device matching table according to the device information update data.

[0081] Based on the above settings, a device matching table update strategy is provided in the event of a storage battery failure during the operation of multiple energy storage cabinets connected in parallel. This strategy can update the device matching table immediately after the battery is replaced to ensure the real-time accuracy of the system status.

[0082] In some of the embodiments, the above-mentioned device identification and matching device 300 also includes a processing module, which is used to: receive the collected data sent by the data collection device based on the energy management system, determine the collection object device according to the collected data and the device matching table, and generate maintenance instructions or control instructions.

[0083] By automatically analyzing the collected data, intelligent monitoring and management of equipment is achieved. Specifically, by accurately identifying equipment that needs maintenance, unnecessary maintenance operations can be avoided; by quickly generating control instructions, necessary adjustments or controls can be made to the equipment to optimize energy use.

[0084] In some of the embodiments, if there are multiple energy storage batteries in the energy storage cabinet, the energy storage battery with the device number recorded in the inverter in the energy storage cabinet is used as the master energy storage battery, and the rest are slave energy storage batteries; the above-mentioned matching module 303 is also used for: the master energy storage battery establishes a communication connection with each slave energy storage battery respectively to obtain and record the serial number of the associated slave energy storage battery; and the device matching table is updated according to the serial number of the master energy storage battery and the serial number of the associated slave energy storage battery.
