[0051] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0052] It should be noted that the terms "object" and "target" in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprises" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or that are inherent to these processes, methods, products or devices.

[0053] Figure 1 This is a flow chart of a method for controlling an energy storage system provided by an embodiment of the present invention. This embodiment is applicable to power dispatching of an energy storage system. This method can be executed by an energy storage system control device, which can be implemented in hardware and / or software. The method specifically includes the following steps:

[0054] S110. Acquire in real time the power dispatch requirements of the user equipment, the user's electricity quotation, and the energy storage information of the energy storage system; wherein the energy storage information includes discharge pricing at multiple different price points, and the user's electricity quotation is the discharge pricing selected by the user based on the urgency of his or her own electricity needs.

[0055] User devices include their electrical appliances and power generation equipment. The power dispatch requirements of user devices include the specific requirements for power provided by the energy storage system and the specific circumstances of the power output by the user devices. The energy storage system's energy storage information primarily records the system's current power storage status, and this information is continuously updated as the system charges and discharges. This energy storage information includes multiple discharge pricing levels, each corresponding to a different power storage system state. For example, discharge pricing A1 corresponds to a power storage system charge of 100%-70%; discharge pricing A2 corresponds to a power storage system charge of 70%-40%; and discharge pricing A3 corresponds to a power storage system charge of 40%-20%.

[0056] In addition, users can select any discharge pricing included in the energy storage information as the user's electricity quotation based on the urgency of their own electricity needs. The criterion for users to select discharge pricing as the user's electricity quotation based on the urgency of their own electricity needs is: the higher the urgency of the user's electricity needs, the higher the discharge pricing selected by the user as the user's electricity quotation. As a result, the subsequent energy storage system can learn the urgency of the user's electricity needs based on the user's electricity quotation and can give priority to power supply. For example, if discharge pricing A1 < discharge pricing A2 < discharge pricing A3, if the user's electricity needs are high, the user can select the highest-priced discharge pricing A3 as the user's electricity quotation, so that the energy storage system can give priority to supplying power to user devices that need electricity urgently. If the user's electricity needs are moderately urgent, the moderately priced discharge pricing A2 can be selected as the user's electricity quotation, so that the energy storage system can supply power to power devices with moderate urgency after supplying power to power devices that need electricity urgently. If the user's electricity demand is low, the lowest discharge pricing A3 can be selected as the user's electricity quotation. In this way, the energy storage system can supply power to the less urgent equipment after supplying power to the moderately urgent equipment.

[0057] Specifically, the power scheduling requirements of user devices include the charging power range, discharging power range, required power, and generated power; the energy storage information also includes the dischargeable power range, rechargeable power range, dischargeable capacity, rechargeable capacity, and charging pricing; each discharge pricing corresponds to a different dischargeable power range and different dischargeable capacity of the energy storage system.

[0058] It should be noted that energy storage systems generally have lower discharge pricing when the discharge power range and discharge capacity are larger, and higher pricing when the discharge power range and discharge capacity are smaller. Charging pricing can be determined based on the discharge capacity of all user devices and the chargeable capacity of the energy storage system. For example, if the discharge capacity of all user devices is greater, the chargeable capacity of the energy storage system is smaller, and the charging pricing is lower. If the discharge capacity of all user devices is smaller, the chargeable capacity of the energy storage system is larger, and the charging pricing is higher.

[0059] In summary, real-time acquisition of user equipment power dispatch requirements, user electricity quotes, and energy storage system information can prepare for subsequent energy storage system control, enabling the energy storage system to flexibly power user equipment, thereby increasing the economic value of the energy storage system.

[0060] S120: Determine the power scheduling requirement of the target user equipment according to the power scheduling requirements of all user equipment and the user electricity quotes.

[0061] The target user device's power dispatch requirement is the power demand of the user device most in need of power among all other user devices. The energy storage system can determine each user's power urgency based on their electricity quotes. Using these quotes, the system then filters the power dispatch requirements of the user devices in urgent need of power, determining the power dispatch requirements of the target user devices so that they can be prioritized for subsequent power supply. This clarifies the power dispatch requirements of the target user devices in urgent need of power, enabling targeted power delivery and enhancing the energy storage system's flexibility in powering these devices, thereby increasing the system's economic value.

[0062] S130: Generate a target user scheduling instruction according to the power scheduling requirement and energy storage information of the target user equipment.

[0063] After determining the power dispatch requirements of the target user device, it is necessary to determine whether the energy storage system can meet the power dispatch requirements of the target user device based on the energy storage information. If the energy storage system cannot meet the power dispatch requirements of the target user device, a target user dispatch instruction is generated based on the energy storage system's available power. If the energy storage system can meet the power dispatch requirements of the target user device, a target user dispatch instruction is generated based on the power dispatch requirements of the target user device.

[0064] For example, if the energy storage system's dischargeable power range is greater than or equal to the target user device's charging power range, and the energy storage system's dischargeable capacity is greater than or equal to the target user device's required power, then the energy storage system can meet the target user device's power scheduling requirements, and a target user scheduling instruction is generated based on the target user device's power scheduling requirements. If the energy storage system's dischargeable power range is less than the target user device's charging power range, or the energy storage system's dischargeable capacity is less than the target user device's required power, then the energy storage system cannot meet the target user device's power scheduling requirements, and a target user scheduling instruction is generated based on the energy storage system's available power.

[0065] In summary, the energy storage information is used to determine whether the energy storage system can meet the power scheduling requirements of the target user equipment, so that the energy storage system can meet the power scheduling requirements of the target user equipment as much as possible within its capabilities, ensuring the normal operation of the energy storage system without affecting other ongoing power supply tasks of the energy storage system.

[0066] S140: Control the energy storage system to provide power to the user equipment according to the target user's dispatch instruction.

[0067] Specifically, the target user scheduling instruction includes the power range that the energy storage system needs to discharge, the amount of electricity to be discharged, and the user equipment that needs to be provided with electricity. Therefore, the energy storage system can be controlled according to the target user scheduling instruction to accurately provide electricity to the user equipment.

[0068] The embodiment of the present invention can prepare for the subsequent control of the power supply of the energy storage system by obtaining the power scheduling requirements of the user equipment, the user's electricity quotation and the energy storage information of the energy storage system in real time. According to the power scheduling requirements and user electricity quotation of all user equipment, the power scheduling requirements of the target user equipment are determined, and the power scheduling requirements of the target user equipment that needs emergency power supply are clarified. Targeted power supply can be provided, which enhances the flexibility of the energy storage system in supplying power to the user equipment, thereby improving the economic value of the energy storage system. According to the power scheduling requirements and energy storage information of the target user equipment, target user scheduling instructions are generated, which can enable the energy storage system to meet the power scheduling requirements of the target user equipment as much as possible within its capabilities, ensure the normal operation of the energy storage system, and will not affect other ongoing power supply tasks of the energy storage system. Controlling the energy storage system to provide power to the user equipment according to the target user scheduling instructions can enable the energy storage system to accurately provide power to the user equipment. In summary, compared with the existing technology, this solution can select a power supply target according to the urgency of the user equipment's power demand, thereby improving the economic value of the energy storage system.

[0069] For example, Figure 2 A flow chart of a method for determining a power scheduling requirement of a target user equipment provided in an embodiment of the present invention is provided. Based on the above embodiment, the method for determining the power scheduling requirement of the target user equipment is further detailed.

[0070] S210: Determine a target price based on electricity quotations from all users.

[0071] The target price refers to the highest current electricity price among all current user electricity quotes. Because user electricity quotes are the discharge pricing of the energy storage system selected by users based on their urgency, the energy storage system must prioritize power supply to users with urgent needs, necessitating a target price.

[0072] S220: Filter the power scheduling requirements of all user equipment corresponding to the target price.

[0073] When multiple users' electricity quotations all correspond to the highest target price, it is necessary to filter out the power dispatch requests of all user devices corresponding to the target price. In other words, the power dispatch requests of user devices with the most urgent electricity needs and the same degree of urgency must be filtered out. This allows the energy storage system to subsequently prioritize power supply to all user devices corresponding to the target price based on the power dispatch requests of all user devices corresponding to the target price, thereby enhancing the flexibility of the energy storage system in supplying power to user devices and improving the economic value of the energy storage system.

[0074] S230: Determine the acquisition time of the power scheduling request of all user equipments corresponding to the target price.

[0075] Among them, in order to further clarify the order of power supply to user devices corresponding to the target price, it is necessary to determine the acquisition time of the power scheduling requirements of all user devices corresponding to the target price, so as to power the user devices corresponding to the target price according to the order of acquisition time of the power scheduling requirements of all user devices corresponding to the target price.

[0076] S240: Determine the power scheduling requirement of the target user equipment according to the time sequence of obtaining the power scheduling requirements of all user equipments corresponding to the target price.

[0077] Specifically, according to the acquisition time sequence of the power scheduling requirements of all user devices corresponding to the target price, the power scheduling requirements of all user devices corresponding to the target price are sorted, and the power scheduling requirement of the user device corresponding to the target price obtained first is selected as the power scheduling requirement of the target user device.

[0078] In summary, through the above method, the power dispatching demands of user devices with the same urgency level can be sorted, and the power dispatching demands of user devices corresponding to the target price obtained first can be responded to first, so that electricity can be supplied according to the first-come, first-served principle. To a certain extent, the flexibility of the energy storage system in supplying power to user devices is enhanced, thereby improving the economic value of the energy storage system.

[0079] For example, Figure 3 A flowchart of another method for determining the power scheduling requirement of a target user equipment provided by an embodiment of the present invention is provided. Based on the above embodiment, the method for determining the power scheduling requirement of a target user equipment is further detailed.

[0080] S310: Sort all users' electricity quotations from high to low.

[0081] S320: According to the ranking of the user electricity quotations, the user electricity quotations are sequentially obtained as target prices.

[0082] S330: Filter the power scheduling requirements of all user equipment corresponding to the target price.

[0083] S340: Determine the acquisition time of the power scheduling requirements of all user equipments corresponding to the target price.

[0084] S350 : According to the time sequence of obtaining the power scheduling requirements of the user equipment corresponding to the target price, sequentially obtain the power scheduling requirements of the user equipment as the power scheduling requirements of the target user equipment.

[0085] For example, if user electricity quotes for five user devices are obtained, the available discharge pricing options for the user electricity quotes include: discharge pricing A1, discharge pricing A2, discharge pricing A3, and discharge pricing A4, with discharge pricing A1 < discharge pricing A2 < discharge pricing A3 < discharge pricing A4. Here, the user electricity quote for user device 1 is discharge pricing A1, the user electricity quote for user device 2 is discharge pricing A2, the user electricity quote for user device 3 is discharge pricing A3, the user electricity quote for user device 4 is discharge pricing A3, and the user electricity quote for user device 5 is discharge pricing A2.

[0086] 1) Sort all user electricity quotations from high to low, and obtain discharge pricing A3> discharge pricing A2> discharge pricing A1.

[0087] 2) Based on the sorting of user electricity quotes, sequentially obtain the user electricity quotes as target prices. Based on the sorting results, first obtain the discharge price A3 corresponding to the user electricity quote as the target price. After powering the user device corresponding to the target price of discharge price A3, obtain the discharge price A2 corresponding to the user electricity quote as the target price. After powering the user device corresponding to the target price of discharge price A2, obtain the discharge price A1 corresponding to the user electricity quote as the target price.

[0088] 3) Filter the power scheduling requirements of all user devices corresponding to the target price. When the target price is the release price A3, the power scheduling requirements of user devices 3 and 4 are filtered out.

[0089] 4) Determine the acquisition time of the power scheduling requirements of all user equipment corresponding to the target price. Among them, the acquisition time of the power scheduling requirements of user equipment 3 is earlier than the acquisition time of the power scheduling requirements of user equipment 4.

[0090] 5) Based on the order in which the power scheduling requirements of the user devices corresponding to the target price levels were obtained, the power scheduling requirements of the user devices are obtained in sequence as the power scheduling requirements of the target user device. The power scheduling requirement of user device 3 is obtained first and used as the power scheduling requirement of the target user device. After powering user device 3, the power scheduling requirement of user device 4 is obtained and used as the power scheduling requirement of the target user device.

[0091] In summary, through the above method, the power dispatching demands of user devices with the same urgency level can be sorted, and the power dispatching demands of user devices corresponding to the target price obtained first can be responded to first, so that electricity can be supplied according to the first-come, first-served principle. To a certain extent, the flexibility of the energy storage system in supplying power to user devices is enhanced, thereby improving the economic value of the energy storage system.

[0092] For example, Figure 4 A flow chart of a method for generating a target user scheduling instruction provided by an embodiment of the present invention is provided. Based on the above embodiment, the method for generating a target user scheduling instruction is further detailed.

[0093] S410. Determine, based on the energy storage information, whether the energy storage system can meet the power scheduling requirements of the target user equipment; if so, execute S420; if not, execute S430.

[0094] Among them, judging whether the energy storage system can meet the power scheduling requirements of the target user equipment based on the energy storage information can enable the energy storage system to meet the power scheduling requirements of the target user equipment as much as possible within its capabilities, thereby ensuring the normal operation of the energy storage system and not affecting the energy storage system's other ongoing power supply tasks.

[0095] S420: Generate a target user scheduling instruction according to the power scheduling requirement of the target user equipment.

[0096] For example, if the dischargeable power range of the energy storage system is greater than or equal to the charging power range of the target user device, and the dischargeable capacity of the energy storage system is greater than or equal to the required power of the target user device, it means that the energy storage system can meet the power scheduling requirements of the target user device. At this time, a target user scheduling instruction is generated according to the power scheduling requirements of the target user device.

[0097] S430: Determine the power supply of the energy storage system according to the energy storage information, and generate a user dispatch instruction according to the power supply.

[0098] For example, if the dischargeable power range of the energy storage system is smaller than the charging power range of the target user device, or the dischargeable capacity of the energy storage system is smaller than the power required by the target user device, it means that the energy storage system cannot meet the power scheduling requirements of the target user device. At this time, a target user scheduling instruction is generated based on the power supply of the energy storage system.

[0099] In summary, generating user dispatch instructions in the above manner can ensure the normal operation of the energy storage system without affecting the energy storage system's impact on other ongoing power supply tasks.

[0100] For example, Figure 5 A flow chart of another energy storage system control method provided by an embodiment of the present invention is shown as follows: Figure 5 As shown, the method specifically includes the following steps:

[0101] S510. Acquire in real time the power dispatch requirements of the user equipment, the user's electricity quotation, and the energy storage information of the energy storage system; wherein the energy storage information includes discharge pricing at multiple different price points, and the user's electricity quotation is the discharge pricing selected by the user based on the urgency of his or her own electricity needs.

[0102] S520: Determine the power scheduling requirement of the target user equipment according to the power scheduling requirements of all user equipments and the user electricity quotes.

[0103] S530: Generate a target user scheduling instruction according to the power scheduling requirement and energy storage information of the target user equipment.

[0104] S540: Control the energy storage system to provide power to the user equipment according to the target user's dispatch instruction.

[0105] S550: Update billing information and energy storage information according to the target user's dispatch instruction.

[0106] Billing information includes whether the transaction was completed, the transaction price, and the amount of electricity consumed. This information is recorded historically and can be accessed and viewed on user devices. The energy storage system's energy storage information primarily records the system's current energy storage status. This information is continuously updated as the system charges and discharges to ensure accuracy and stability.

[0107] Optionally, based on the above embodiment, updating the energy storage information of the energy storage system is further detailed: updating the energy storage information of the energy storage system includes: updating the chargeable and dischargeable power range of the energy storage system; updating the chargeable and dischargeable capacity of the energy storage system; adjusting each discharge pricing according to the chargeable and dischargeable power range and the chargeable and dischargeable capacity; or adjusting the discharge pricing according to the historical power scheduling requirements of all user devices; and generating a discharge pricing list according to the adjusted discharge pricing.

[0108] Figure 6 A schematic diagram of the structure of an energy storage system control device provided by an embodiment of the present invention is shown in FIG. Figure 6 As shown, the energy storage system control device includes:

[0109] An acquisition module 610 is configured to acquire, in real time, the power dispatch requirements of user equipment, user electricity quotes, and energy storage information of the energy storage system; wherein the energy storage information includes multiple discharge pricings, and the user electricity quote is the discharge pricing selected by the user;

[0110] The target user equipment power scheduling requirement determination module 620 is used to determine the power scheduling requirement of the target user equipment based on the power scheduling requirements of all user equipments and user electricity quotes;

[0111] The target user scheduling instruction generation module 630 is used to generate a target user scheduling instruction according to the power scheduling requirements and energy storage information of the target user equipment;

[0112] The allocation module 640 is used to control the energy storage system to provide power to the user equipment according to the target user scheduling instruction.

[0113] In this embodiment of the present invention, acquisition module 610 acquires user device power scheduling requirements, user electricity quotes, and energy storage system energy storage information in real time, preparing for subsequent energy storage system power supply control. Target user device power scheduling requirement determination module 620 determines the target user device's power scheduling requirements based on the power scheduling requirements and user electricity quotes of all user devices. This clarifies the power scheduling requirements of target user devices requiring emergency power supply, enabling targeted power supply and enhancing the energy storage system's flexibility in powering user devices, thereby improving the economic value of the energy storage system.
