Description

Technical Field

[0001] This invention relates to the field of energy storage control technology, and in particular to a collaborative control method, device, equipment and medium for co-located heterogeneous energy storage systems. Background Technology

[0002] With the advancement of new power system construction, electrochemical energy storage power stations are gradually showing a diversified layout trend. Grid-side energy storage mainly undertakes public service functions such as grid frequency regulation, peak shaving, backup, and reactive power support, while user-side energy storage focuses on meeting the self-consumption needs of enterprises, such as peak-valley electricity price response, load smoothing, and uninterrupted power supply. Currently, most energy storage power station construction in the industry adopts a single-function layout model. Even in scenarios where two types of energy storage are built in the same area, many technical challenges remain.

[0003] (1) Serious waste of hardware resources: The two types of energy storage power stations are independently configured with booster stations, outgoing line bays, fire protection and auxiliary facilities, resulting in high duplication of investment and low land utilization. Especially in industrial parks where land resources are scarce, construction and operation and maintenance costs remain high.

[0004] (2) Poor scheduling coordination: The independent control and data fragmentation of energy storage on the grid side and the user side make it impossible to achieve complementary power allocation, which can easily lead to problems such as charging and discharging conflicts and delayed response to grid fluctuations, making it difficult to meet the dual needs of grid service and user self-use.

[0005] (3) High risk of grid connection at close range: When large-capacity energy storage power stations are connected to high-voltage substations at close range, problems such as circulating current, voltage sudden change and harmonic interference occur frequently, and there is a lack of targeted grid-storage linkage protection mechanism;

[0006] (4) Rigid mode switching: It is impossible to achieve seamless switching between grid-connected mode and self-use mode, resulting in low energy storage utilization and failure to maximize overall benefits.

[0007] For special areas such as petrochemical zones, where the grid-side and user-side energy storage stations are located on the same plot of land, existing control technologies cannot be adapted to this unique scenario. Therefore, there is an urgent need for a method that can achieve shared voltage boosting, coordinated control, and safe grid connection to fill the technological gap in the industry. Summary of the Invention

[0008] In view of the above, it is necessary to provide a collaborative control method, device, equipment and medium for co-located heterogeneous energy storage systems, aiming to solve the problems of high waste of control resources, poor scheduling coordination, prominent risks of close-range grid connection and rigid mode switching for co-located heterogeneous energy storage systems.

[0009] A collaborative control method for a co-located heterogeneous energy storage system is proposed, applied to such a system. The co-located heterogeneous energy storage system includes a grid-side energy storage unit, a user-side energy storage unit, a shared booster station, and an intelligent switching interlocking device. The collaborative control method for the co-located heterogeneous energy storage system includes:

[0010] In response to the coordinated control command of the co-located heterogeneous energy storage system, multi-source data of the co-located heterogeneous energy storage system are collected in real time.

[0011] The target operating mode is obtained by analyzing the multi-source data.

[0012] The intelligent switching interlocking device seamlessly switches the co-located heterogeneous energy storage system to the target operating mode.

[0013] Based on the collaborative power scheduling strategy, the shared booster station assists the co-located heterogeneous energy storage system in executing the target operation mode;

[0014] During the execution of the target operation mode, when the electrical distance between the shared booster station and the substation busbar is less than a preset low threshold, the intelligent switching interlocking device performs linkage protection.

[0015] A collaborative control device for a co-located heterogeneous energy storage system is disclosed, operating within the co-located heterogeneous energy storage system, which includes a grid-side energy storage unit, a user-side energy storage unit, a shared booster station, and an intelligent switching interlocking device. The collaborative control device for the co-located heterogeneous energy storage system includes:

[0016] The acquisition unit is used to acquire multi-source data of the co-located heterogeneous energy storage system in real time in response to the coordinated control command of the co-located heterogeneous energy storage system.

[0017] The analysis unit is used to analyze the multi-source data to obtain the target operating mode;

[0018] The switching unit is used to seamlessly switch the co-located heterogeneous energy storage system to the target operating mode through the intelligent switching interlocking device.

[0019] An execution unit is used to assist the co-located heterogeneous energy storage system in executing the target operation mode based on a collaborative power scheduling strategy through the shared booster station.

[0020] The execution unit is also used to perform linkage protection through the intelligent switching interlocking device when the electrical distance between the shared booster station and the substation busbar is less than a preset low threshold during the execution of the target operation mode.

[0021] A computer device, the computer device comprising:

[0022] A memory for storing at least one instruction; and a processor for executing the instructions stored in the memory to implement the collaborative control method for the co-located heterogeneous energy storage system.

[0023] A computer-readable storage medium storing at least one instruction, which is executed by a processor in a computer device to implement the collaborative control method for a co-located heterogeneous energy storage system.

[0024] As can be seen from the above technical solutions, this invention can analyze multi-source data to obtain the target operating mode, and seamlessly switch the co-located heterogeneous energy storage system to the target operating mode through an intelligent switching interlocking device, achieving seamless mode switching. Based on the collaborative power dispatch strategy, the shared booster station assists the co-located heterogeneous energy storage system in executing the target operating mode, which can take into account both grid service and user self-use, without dispatching conflicts, and can improve hardware utilization. During the execution of the target operating mode, when the electrical distance between the shared booster station and the substation bus is less than a preset low threshold, the intelligent switching interlocking device performs linkage protection, which can solve the problems of short-distance grid-connected circulating current, voltage fluctuation, and harmonic interference, ensuring grid-connected safety and stability.

[0027] Figure 3 This is a schematic diagram of the computer equipment used in a preferred embodiment of the method for collaborative control of co-located heterogeneous energy storage systems according to the present invention. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 The diagram shown is a flowchart of a preferred embodiment of the collaborative control method for co-located heterogeneous energy storage systems according to the present invention. The order of steps in this flowchart can be changed, and some steps can be omitted, depending on different requirements.

[0030] The co-located heterogeneous energy storage system collaborative control method is applied to one or more computer devices. The computer device is a device that can automatically perform numerical calculations and / or information processing according to pre-set or stored instructions. Its hardware includes, but is not limited to, microprocessors, application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), digital signal processors (DSPs), embedded devices, etc.

[0031] The computer device can be any electronic product that can interact with the user, such as a personal computer, tablet computer, smartphone, personal digital assistant (PDA), game console, interactive network television (IPTV), smart wearable device, etc.

[0032] The computer equipment may also include network equipment and / or user equipment. The network equipment includes, but is not limited to, a single network server, a server group consisting of multiple network servers, or a cloud based on cloud computing consisting of a large number of hosts or network servers.

[0033] The server can be a standalone server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0034] Artificial intelligence (AI) is the theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results.

[0035] Foundational technologies for artificial intelligence generally include sensors, dedicated AI chips, cloud computing, distributed storage, big data processing, operating / interactive systems, and mechatronics. AI software technologies mainly encompass computer vision, robotics, biometrics, speech processing, natural language processing, and machine learning / deep learning.

[0036] The network in which the computer device is located includes, but is not limited to, the Internet, wide area network, metropolitan area network, local area network, and virtual private network (VPN).

[0037] In this embodiment, the collaborative control method for co-located heterogeneous energy storage systems is applied to co-located heterogeneous energy storage systems, which include grid-side energy storage units, user-side energy storage units, shared booster stations, and intelligent switching interlocking devices.

[0038] The shared booster station can be a 110kV booster station.

[0039] The grid-side energy storage unit can be a 200MW or 400MWh electrochemical energy storage system.

[0040] The co-located heterogeneous energy storage system may also include auxiliary facilities, such as a shared fire pump room, temperature control system, and monitoring system.

[0041] The collaborative control method for co-located heterogeneous energy storage systems is applicable to complex load scenarios such as industrial parks and petrochemical industrial zones. It allows for the separate establishment of grid-side and user-side heterogeneous energy storage power stations on the same site, while sharing the booster station equipment. It is particularly suitable for large-capacity energy storage projects that are connected to high-voltage substations in close proximity.

[0042] S10, in response to the coordinated control command of the co-located heterogeneous energy storage system, collects multi-source data of the co-located heterogeneous energy storage system in real time.

[0043] In this embodiment, the collaborative control command can be triggered when the co-located heterogeneous energy storage system is put into use.

[0044] In this embodiment, the collection of multi-source data from the co-located heterogeneous energy storage system includes:

[0045] Real-time acquisition of grid-side dispatch commands and substation operating parameters of the grid-side energy storage unit;

[0046] Real-time load data of the user-side energy storage unit is collected.

[0047] Real-time acquisition of energy storage unit status data and shared booster station equipment status data;

[0048] All the collected data are integrated to obtain the multi-source data.

[0049] The grid-side dispatch instructions may include frequency regulation, peak load, reactive power support, grid connection permission, etc.

[0050] The real-time load data on the user side may include the power consumption of enterprises in the petrochemical park, peak and off-peak electricity price periods, and electricity priority.

[0051] The energy storage unit status data may include SOC (State of Charge), charging and discharging power, temperature, voltage, fault signals, etc.

[0052] The substation operating parameters can be 220kV substation operating parameters, which may include electrical quantities such as bus voltage, bus current, and zero-sequence current, signal quantities such as circuit breaker opening and closing status, protection action signals, grid connection permission signals, and fault alarm signals, as well as operating conditions such as grid frequency, grid dispatching instructions, and current load level.

[0053] The shared booster station equipment status data may include main transformer equipment data such as oil temperature, winding temperature, oil level, gas relay status, tap position, and partial discharge quantity; switchgear data such as GIS (Gas Insulated Switchgear) status, disconnector status, and grounding switch status; auxiliary equipment data such as cooler operating status, fire alarm signal, DC power supply status, and ambient temperature and humidity; and electrical quantities such as current, voltage, power, and load factor.

[0054] In this embodiment, after collecting multi-source data from the co-located heterogeneous energy storage system, the method further includes:

[0055] The multi-source data is preprocessed, and abnormal data in the multi-source data is detected.

[0056] Specifically, abnormal data can be detected and removed through two steps: hardware-level filtering and algorithm-level verification.

[0057] For example, at the hardware level, absolute ranges can be set for parameters such as voltage, current, and temperature, combined with equipment parameters. If the voltage acquisition value of a 110kV booster station exceeds the reasonable range of 100kV-130kV, it is directly judged as data distortion and the data can be discarded. The parameter change rate within adjacent sampling periods can also be calculated for abrupt change filtering. If the change rate exceeds the preset safety slope (e.g., voltage abrupt change rate > 5% / s), it is judged as interference pulse or sensor failure and the data can be discarded. The quality flag of the acquisition card or sensor can also be checked. If the flag displays "data overflow or sensor offline or verification error", the corresponding data is directly determined as invalid data. At the algorithm level, data continuity can be verified. For example, if the same parameter remains unchanged for multiple consecutive sampling periods (e.g., static data), and the actual operating logic of the equipment cannot remain static, it is determined that the data is stuck or the transmission is interrupted, and it can be removed and supplemented (or null values ​​can be retained). Data can also be cross-validated for logical consistency. For example, if the grid-side dispatch command shows "grid connected", but the substation circuit breaker status is "open", it is determined that there is a data logic contradiction, and the erroneous command can be removed based on the hardware status. Anomalies can also be smoothed. For isolated abnormal noise points (e.g., instantaneous sensor jitter), median filtering or moving average methods can be used for correction instead of direct removal, in order to preserve data validity.

[0058] The above embodiments can provide accurate data support for subsequent mode determination and power scheduling, avoiding control errors caused by data anomalies.

[0059] S11, Analyze the multi-source data to obtain the target operating mode.

[0060] In this embodiment, the analysis of the multi-source data to obtain the target operating mode includes:

[0061] When an emergency grid dispatch command is detected in the grid-side dispatch command, the target operating mode is determined to be the grid priority mode; or

[0062] Based on the multi-source data, the period of no power grid dispatch instructions is determined, and the target operating mode corresponding to the period of no power grid dispatch instructions is determined as the user self-use mode; or

[0063] Based on the multi-source data, the mixed time periods of regular power grid scheduling and stable user load are determined, and the target operating mode corresponding to the mixed time periods is determined as the collaborative mixed mode.

[0064] The emergency power grid dispatch instructions may include frequency regulation, peak load, and other dispatch instructions.

[0065] The above embodiments enable the determination of the operating mode according to specific needs.

[0066] S12, the co-located heterogeneous energy storage system is seamlessly switched to the target operating mode through the intelligent switching interlocking device.

[0067] In this embodiment, the step of seamlessly switching the co-located heterogeneous energy storage system to the target operating mode via the intelligent switching interlocking device includes:

[0068] When the target operating mode is the grid priority mode, the independent charging and discharging rights of the user-side energy storage unit are locked by the intelligent switching interlocking device, the grid-side energy storage unit responds to the scheduling of the grid-side energy storage unit at full power, and the user-side energy storage unit is controlled to enter standby mode; or

[0069] When the target operating mode is the user-only mode, the independent charging and discharging permissions of the grid-side energy storage unit are locked by the intelligent switching interlocking device. The user-side energy storage unit is responded to based on real-time load data, and the grid-side energy storage unit is controlled to enter standby mode; or

[0070] When the target operating mode is the collaborative hybrid mode, the charging and discharging permissions of the grid-side energy storage unit and the user-side energy storage unit are simultaneously opened through the intelligent switching interlocking device, so that the grid-side energy storage unit and the user-side energy storage unit can operate in parallel.

[0071] The step of responding to the user-side energy storage unit by combining the real-time load data of the user side may include: combining peak-valley electricity prices and park load to control the user-side energy storage unit to perform peak-valley electricity price response and load smoothing.

[0072] S13, based on the collaborative power scheduling strategy, the shared booster station assists the co-located heterogeneous energy storage system in executing the target operation mode.

[0073] In this embodiment, the step of using the shared booster station to assist the co-located heterogeneous energy storage system in executing the target operating mode based on the cooperative power scheduling strategy includes:

[0074] When the target operating mode is the grid priority mode, the grid-side energy storage unit's grid-connected output is fully received by the shared booster station; or

[0075] When the target operating mode is the user-owned mode, control the shared booster station to switch to the booster channel of the user-side energy storage unit; or

[0076] When the target operating mode is the collaborative hybrid mode, the grid-side energy storage unit is controlled by the shared booster station to prioritize responding to the grid's active or reactive power demand based on the grid dispatch curve, and the user-side energy storage unit is controlled to prioritize responding to the target park load. The charging and discharging sequence is optimized according to the electricity price signal, and power diversion and circulating current suppression are performed on the grid-side energy storage unit and the user-side energy storage unit. In the collaborative hybrid mode, the grid-side energy storage unit and the user-side energy storage unit share the booster transformer, the gas-insulated metal-enclosed switchgear bay, and the external transmission line.

[0077] Through the above embodiments, seamless switching between three operating modes can be achieved, balancing grid service and user self-use, without scheduling conflicts or charging / discharging conflicts. Furthermore, the intelligent switching interlocking device also achieves power diversion and circulating current suppression, avoiding overload problems of the booster equipment and improving hardware utilization.

[0078] S14, during the execution of the target operation mode, when the electrical distance between the shared booster station and the substation bus is less than a preset low threshold, the linkage protection is executed through the intelligent switching interlocking device.

[0079] In this embodiment, considering the characteristics of ultra-close-range substation access, the electrical quantities of the grid-connected node, such as voltage, current, and harmonics, are monitored in real time.

[0080] Specifically, the execution of the linkage protection through the intelligent switching interlocking device includes:

[0081] Real-time monitoring of electrical quantities at grid-connected nodes based on the substation's operating parameters;

[0082] When it is determined from the electrical quantities of the grid-connected node that circulating current exceeds the limit, and / or voltage changes suddenly, and / or harmonic disturbances occur, the output power of the corresponding energy storage unit is adjusted and reactive power compensation is initiated.

[0083] Fault detection is performed based on the status data of the energy storage unit and the status data of the shared booster station equipment.

[0084] When a fault is detected, the faulty circuit is instantly cut off by the intelligent switching interlocking device.

[0085] The intelligent switching interlocking device can instantly cut off the faulty circuit, ensuring the normal operation of non-faulty units and avoiding impact on the substation.

[0086] The above embodiments can solve problems such as short-distance grid-connected circulating current, voltage fluctuations, and harmonic interference, ensuring safe and stable grid connection.

[0087] In this embodiment, the method further includes:

[0088] Real-time monitoring of the operating status of the grid-side energy storage unit and the user-side energy storage unit;

[0089] When the temperature of the target battery compartment is determined to be higher than the temperature threshold based on the operating status, the cooling equipment of the corresponding zone of the target battery compartment is activated; and / or

[0090] When the smoke concentration in the target area is determined to be higher than the smoke concentration threshold based on the operating status, the fire protection system of the corresponding zone of the target area is activated.

[0091] The temperature threshold and the smoke concentration threshold can be configured according to actual safety requirements.

[0092] Through the above embodiments, it is possible to integrate data from the entire system, realize remote operation and maintenance, fault alarm, and data traceability, and at the same time realize the sharing of auxiliary facilities, reduce operation and maintenance costs, and improve the safety of energy storage system.

[0093] This embodiment addresses the drawbacks of existing heterogeneous energy storage power stations being independently constructed and controlled. By combining the core features of being located on the same plot and connected to high-voltage substations in close proximity, it achieves shared step-up hardware, hierarchical power scheduling, flexible mode switching, and grid-storage safety linkage. It solves problems such as duplicate investment, scheduling conflicts, and instability of close-range grid connection, improves energy storage utilization and overall benefits, and can ensure the reliability of power supply in petrochemical parks and the safety of grid operation.

[0094] Specifically, by sharing hardware such as booster stations, fire protection, and temperature control, redundant investment can be reduced, land utilization and comprehensive energy storage utilization can be improved, resulting in significant cost reduction and efficiency improvement. Seamless switching between three modes balances grid service and user self-use, enabling rapid power allocation without dispatch conflicts, adapting to the stable power supply needs of petrochemical parks, and providing flexible and reliable dispatch. Simultaneously, it can specifically address issues such as short-distance grid-connected circulating current and voltage fluctuations, with rapid response from grid-storage linkage protection, ensuring the safe operation of substations and energy storage systems, and making grid connection safe and controllable. Furthermore, this solution aligns with the integrated energy storage construction needs of industrial parks and petrochemical zones, and the layout scheme for the same site can be replicated and promoted, conforming to the new power system's integrated source-grid-load-storage policy, and possessing strong scenario adaptability.

[0095] As can be seen from the above technical solutions, this invention can analyze multi-source data to obtain the target operating mode, and seamlessly switch the co-located heterogeneous energy storage system to the target operating mode through an intelligent switching interlocking device, achieving seamless mode switching. Based on the collaborative power dispatch strategy, the shared booster station assists the co-located heterogeneous energy storage system in executing the target operating mode, which can take into account both grid service and user self-use, without dispatching conflicts, and can improve hardware utilization. During the execution of the target operating mode, when the electrical distance between the shared booster station and the substation bus is less than a preset low threshold, the intelligent switching interlocking device performs linkage protection, which can solve the problems of short-distance grid-connected circulating current, voltage fluctuation, and harmonic interference, ensuring grid-connected safety and stability.

[0096] like Figure 2 The diagram shown is a functional block diagram of a preferred embodiment of the collaborative control device for a co-located heterogeneous energy storage system according to the present invention. The collaborative control device 11 operates within a co-located heterogeneous energy storage system, which includes a grid-side energy storage unit, a user-side energy storage unit, a shared booster station, and an intelligent switching interlocking device.

In this invention, a module / unit refers to a series of computer program segments that can be executed by a processor and perform a fixed function, stored in a memory. In this embodiment, the functions of each module / unit will be detailed in subsequent embodiments.

[0097] The acquisition unit 110 is used to collect multi-source data of the co-located heterogeneous energy storage system in real time in response to the collaborative control command of the co-located heterogeneous energy storage system.

[0098] The analysis unit 111 is used to analyze the multi-source data to obtain the target operating mode;

[0099] The switching unit 112 is used to seamlessly switch the co-located heterogeneous energy storage system to the target operating mode through the intelligent switching interlocking device.

[0100] The execution unit 113 is used to assist the co-located heterogeneous energy storage system in executing the target operation mode based on the cooperative power scheduling strategy through the shared booster station.

[0101] The execution unit 113 is also used to perform linkage protection through the intelligent switching interlocking device when the electrical distance between the shared booster station and the substation busbar is less than a preset low threshold during the execution of the target operation mode.

[0102] As can be seen from the above technical solutions, this invention can analyze multi-source data to obtain the target operating mode, and seamlessly switch the co-located heterogeneous energy storage system to the target operating mode through an intelligent switching interlocking device, achieving seamless mode switching. Based on the collaborative power dispatch strategy, the shared booster station assists the co-located heterogeneous energy storage system in executing the target operating mode, which can take into account both grid service and user self-use, without dispatching conflicts, and can improve hardware utilization. During the execution of the target operating mode, when the electrical distance between the shared booster station and the substation bus is less than a preset low threshold, the intelligent switching interlocking device performs linkage protection, which can solve the problems of short-distance grid-connected circulating current, voltage fluctuation, and harmonic interference, ensuring grid-connected safety and stability.

Furthermore, the memory 12 can include both internal storage units and external storage devices of the computer device 1. The memory 12 can be used not only to store application software and various types of data installed on the computer device 1, such as the code of the collaborative control program for a co-located heterogeneous energy storage system, but also to temporarily store data that has been output or will be output.

[0108] In some embodiments, the processor 13 may be composed of integrated circuits, such as a single packaged integrated circuit or multiple integrated circuits with the same or different functions, including combinations of one or more central processing units (CPUs), microprocessors, digital processing chips, graphics processors, and various control chips. The processor 13 is the control unit of the computer device 1, connecting various components of the computer device 1 via various interfaces and lines. It executes programs or modules stored in the memory 12 (e.g., executing a collaborative control program for a co-located heterogeneous energy storage system) and calls data stored in the memory 12 to perform various functions of the computer device 1 and process data.

[0109] The processor 13 executes the operating system of the computer device 1 and various installed application programs.

Figure 3 The bus is represented by only one straight line, but this does not mean that there is only one bus or one type of bus. The bus is configured to enable communication between the memory 12 and at least one processor 13, etc.

[0117] Although not shown, the computer device 1 may also include a power supply (such as a battery) to power various components. Preferably, the power supply can be logically connected to the at least one processor 13 through a power management device, thereby enabling functions such as charging management, discharging management, and power consumption management.
