Description

Energy storage unit energy dispatching methods, devices, computer equipment and storage media Technical Field

[0001] This application relates to the field of artificial intelligence technology, and in particular to an energy dispatching method, apparatus, computer equipment, storage medium and computer program product for an energy storage unit. Background Technology

[0002] When the power balance in a power grid zone is under strain, real-time power grid dispatching can maintain the power generation and consumption balance within a zone through pre-control measures such as rapid load transfer between zones, thereby preventing power flow from exceeding limits at main transformers or transmission sections and ensuring the safe operation of the power grid.

[0003] In grid zones with centralized access to large-scale energy storage, reasonable power dispatch can be implemented through centralized control of large-scale energy storage during peak and off-peak periods, periods of high clean energy generation with deep peak shaving by thermal power units, periods of fluctuating clean energy output, and periods of insufficient thermal power regulation capacity. This addresses issues such as transmission line congestion, transformer peak load, and power flow control. However, existing energy dispatch methods are not flexible enough in responding to actual situations during centralized control and cannot flexibly adjust dispatch strategies according to the actual conditions of energy storage units.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] The energy dispatching method for energy storage units provided in this application embodiment can be applied to the application environment shown in Figure 1. The terminal 102 communicates with the server 104 via a network. The terminal 102 is used to obtain the overall regulation target and also to obtain the energy storage configuration data of individual energy storage units. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104 or placed on the cloud or other network servers. The data storage system can be used to store the energy storage configuration data of individual energy storage units, wherein the energy storage configuration data is used to calculate energy storage status data. The data storage system can also be used to cache the operating status data and energy storage status data of energy storage units in real time, and to store information such as historical dispatch records. The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. The terminal 102 can also include various sensors and detection devices, such as voltage detection devices and current detection devices. The server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.

[0058] In an exemplary embodiment, as shown in FIG2, an energy dispatching method for energy storage units is provided. This method can be used in a centralized energy dispatching system, which includes multiple energy storage units. Taking the application of this method to server 104 in FIG1 as an example, the method includes the following steps S202 to S208. Wherein:

[0059] Step S202: Obtain the overall regulation target of energy dispatch and the initial operating status data of multiple energy storage units to be dispatched.

[0060] The centralized energy dispatch system includes multiple energy storage units, which can be divided into dispatchable and non-dispatchable energy storage units. For example, dispatchable energy storage units can be energy storage batteries, energy storage power stations, etc., while non-dispatchable energy storage units can be energy storage power stations that use clean energy sources with relatively poor energy stability as their energy source. The initial operating status data can include operating power data and charge / discharge status. Operating power data characterizes the current energy change power of the energy storage unit, such as charging power and discharging power; charge / discharge status characterizes whether the energy storage unit is currently in a charging or discharging state.

[0061] For example, server 104 can directly obtain the overall regulation target for energy dispatch from terminal 102, or it can obtain the overall regulation target from other servers. Server 104 can obtain the initial operating status data of the energy storage units to be dispatched in the system at the current moment from terminal 102.

[0062] For example, server 104 can also count the total active power of unschedulable energy storage units, and then calculate the overall regulation target of energy dispatching for the energy storage system based on the total active power. The calculation formula is:

[0063] Among them, P′ Ss P represents the total regulation target of dispatchable energy storage units; l represents the number of undispatchable energy storage units; gen,j P represents the actual output power of energy storage unit j. Ss The overall target of the centralized scheduling system is received by terminal 102 and sent to server 104, or it can be obtained by server 104 from other servers.

[0064] Step S204: Based on the overall regulation target and initial operating status data, perform charge / discharge state transitions on the energy storage units to be scheduled to obtain the current operating status data of each energy storage unit to be scheduled.

[0065] For example, server 104 can filter out energy storage units whose actual power output is opposite to the overall adjustment target of the schedulable energy storage units, and perform charge / discharge conversion on them. If the adjustment target is positive, the energy storage units in the charging state are sequentially switched to standby (i.e., 0 power); conversely, if the adjustment target is negative, the energy storage units in the discharging state are sequentially switched to standby (i.e., 0 power). After the charge / discharge state conversion, server 104 can calculate the adjustment result of the charge / discharge conversion by calculating the current operating status data of each energy storage unit to be scheduled.

[0066] Among them, the control target P of energy storage unit j des,j for:

[0067] Where u is the total adjustment target P′ Ss The reverse energy storage unit j is called in descending order of its actual power output amplitude; P′ Ss (0)=P′ Ss ;P′ Ss (u)=P′ Ss (u-1)+Pgen,u-1(u≥1).

[0068] Step S206: Calculate the charge and discharge regulation results based on the current operating status data, and if the charge and discharge regulation results do not reach the overall regulation target, obtain the current energy storage status data of each energy storage unit to be scheduled.

[0069] Among them, energy storage state data can be used to characterize the charge state of energy storage units. For example, energy storage state data can be SOC (State of Charge) data, which is the ratio of the electrical energy stored in the battery to its rated capacity. SOC is usually expressed as a percentage. For example, a battery with an SOC of 80% means that the battery has stored 80% of its rated capacity of electrical energy.

[0070] For example, if the charge / discharge regulation result does not reach the overall regulation target, the server 104 can obtain the current energy storage data of the energy storage unit from the terminal 102, and then obtain the rated capacity data of the energy storage unit from the data storage system, thereby calculating the SOC data.

[0071] Step S208: Continue to perform energy scheduling on multiple energy storage units to be scheduled based on the energy storage status data, so as to update the current operating status data until the charging and discharging regulation results reach the overall regulation target.

[0072] In the aforementioned energy storage unit energy dispatching method, by acquiring the overall energy dispatching target and the initial operating status data of multiple energy storage units to be dispatched, the initial charging and discharging states and other operating conditions of the multiple energy storage units to be dispatched can be obtained. Then, based on the overall dispatching target and the initial operating status data, the charging and discharging states of the energy storage units to be dispatched are converted, obtaining the current operating status data of each energy storage unit after the conversion. Next, the charging and discharging adjustment result is calculated based on the current operating status data, allowing us to determine whether the energy storage system, including multiple energy storage units, can achieve the overall dispatching target after the charging and discharging state conversion. If the charging and discharging adjustment result does not reach the overall dispatching target, the current energy storage status data of each energy storage unit to be dispatched is acquired, and energy dispatching continues for multiple energy storage units to be dispatched based on the energy storage status data to update the current operating status data until the charging and discharging adjustment result reaches the overall dispatching target. This allows for the determination of a dispatching scheme based on the actual situation of different energy storage units. Therefore, the above method can flexibly acquire the energy storage status of individual energy storage units even when the overall dispatching target cannot be achieved after the charging and discharging conversion process, and then flexibly adjust the dispatching scheme according to the actual situation of each energy storage unit, improving the flexibility of energy dispatching.

[0073] In an exemplary embodiment, the initial operating status data includes operating power data and charge / discharge status; step S204 may include: selecting energy storage units to be converted based on the overall regulation target and the charge / discharge status of each energy storage unit to be scheduled; sorting each energy storage unit to be converted based on the operating power data to obtain a conversion order; and converting the charge / discharge status of the energy storage units to be converted sequentially according to the conversion order.

[0074] For example, server 104 can first determine the power output direction required by the overall regulation target, then filter the energy storage units whose current power output direction is opposite to the overall regulation target, and take these energy storage units as energy storage units to be converted. Then, it can obtain the current operating power data of these energy storage units to be converted, that is, the charging / discharging power, and sort each energy storage unit to be converted according to the operating power data to obtain the conversion order. Then, according to the conversion order, the charging and discharging state of the energy storage units to be converted is converted in sequence. When the energy demand indicated by the overall regulation target is greater than the preset regulation threshold, the energy storage unit with the larger current output power amplitude is given priority for charging and discharging conversion. When the energy demand indicated by the overall regulation target is less than or equal to the preset regulation threshold, the energy storage unit with the smaller current output power amplitude is given priority for charging and discharging conversion.

[0075] In an exemplary embodiment, as shown in FIG3, step S208 includes steps S302 to S306. Wherein:

[0076] Step S302: Based on the energy storage status data, determine the type of energy dispatch mode required at present, wherein the energy storage status data is used to characterize the proportion of energy stored in the energy storage unit to be dispatched to the rated capacity.

[0077] For example, server 104 can calculate the available power based on the proportion of energy stored in the energy storage unit to the rated capacity, and then determine the type of energy dispatching mode required at present based on the available power. The available power is defined as:

[0078] Where, γ j P represents the available electrical energy of energy storage unit j; cap Rated capacity; S is the percentage of available power; P″ Ss This represents the remaining unallocated capacity after the state transition.

[0079] Step S304: If the difference in the energy storage status data between two energy storage units to be scheduled exceeds a preset difference threshold, the energy scheduling method of the first scheduling type is used to schedule the energy of multiple energy storage units to be scheduled.

[0080] Energy storage units with different states of charge (SOCs) will exhibit different performance characteristics. If the SOCs of the batteries in the system are inconsistent, some energy storage units may reach their charging or discharging thresholds prematurely, thereby reducing the overall performance and lifespan of the system. Therefore, avoiding inconsistencies in SOC values ​​can ensure the stability, reliability, and performance of the energy storage system, reduce performance loss, and maintain system stability and safety.

[0081] For example, server 104 can sort multiple energy storage units to be scheduled based on energy storage status data to obtain priority information for each unit, and then perform energy scheduling on each unit according to priority order. When there is a large difference in SOC values ​​between different energy storage units, using the first scheduling type of energy scheduling method can quickly reduce the difference in SOC values ​​between different energy storage units. The SOC margin value can be defined as:

[0082] Where, η j Let be the SOC margin of energy storage unit j.

[0083] The energy storage units are activated sequentially according to their SOC margin, from largest to smallest. The control objective for the energy storage units is:

[0084] Where m is the sequence number of the SOC margin in descending order.

[0085] Step S306: If the numerical difference indicated by the energy storage status data between any two energy storage units to be scheduled does not exceed the preset difference threshold, the energy scheduling method of the second scheduling type is used to schedule the energy of multiple energy storage units to be scheduled.

[0086] For example, server 104 can calculate the energy scheduling target for each energy storage unit to be scheduled based on its energy storage status data, and simultaneously perform energy scheduling for multiple energy storage units according to their respective energy scheduling targets. The initial allocation result of the energy scheduling targets for the energy storage units can be:

[0087] Among them, P des,j Let be the energy scheduling target of energy storage unit j; n is the total number of schedulable energy storage units.

[0088] Furthermore, server 104 can also verify the initial allocation result against the maximum charging / discharging power of the energy storage unit, and iteratively correct the initial allocation result:

[0089] When the allocation result P des,j ≤P cmx,j j or P des,j ≥P dmx,j When, then P des,j Corrected to P respectively cmx,j or P dmx,j When the allocation result P des,j >P cmx,j j or P des,j <P dmx,j hour,

[0090] Among them, P′ des,j Let m be the energy scheduling target of energy storage unit j; m be the total number of energy storage units with adjustable SOC margin; and n-m be the total number of energy storage units that have been corrected.

[0091] In another exemplary embodiment, server 104 obtains the overall energy dispatching target from other servers and obtains the initial operating status data of the energy storage units to be dispatched in the system at the current moment from terminal 102. Next, server 104 first determines the power output direction required by the overall dispatching target, then filters the energy storage units whose current power output direction is opposite to the overall dispatching target, and takes these energy storage units as the energy storage units to be converted. Subsequently, it obtains the current charging / discharging power of these energy storage units to be converted, and sorts each energy storage unit to be converted according to the operating power data to obtain the conversion order. Then, according to the conversion order, it converts the charging and discharging state of the energy storage units to be converted in sequence. When the energy demand indicated by the overall dispatching target is greater than the preset dispatching threshold, the energy storage units with larger current output power amplitude are given priority for charging and discharging conversion. When the energy demand indicated by the overall dispatching target is less than or equal to the preset dispatching threshold, the energy storage units with smaller current output power amplitude are given priority for charging and discharging conversion.

[0092] Subsequently, if the charging and discharging adjustment results do not meet the overall adjustment target, server 104 obtains the current energy storage data of the energy storage unit from terminal 102, and then obtains the rated capacity data of the energy storage unit from the data storage system, thereby calculating the SOC data. Server 104 calculates the available power based on the proportion of energy stored in the energy storage unit to its rated capacity, and then determines the type of energy dispatching mode required based on the available power.

[0093] When the difference in SOC values ​​between two energy storage units to be scheduled exceeds a preset threshold, server 104 employs a first-type energy scheduling method to schedule multiple energy storage units: The energy storage units are sorted according to their SOC values ​​to obtain priority information, and then energy is scheduled one by one according to their priority order. When there is a significant difference in SOC values ​​between different energy storage units, using the first-type energy scheduling method can quickly reduce the difference in SOC values ​​between them.

[0094] When the difference between the energy storage status data of any two energy storage units to be scheduled does not exceed the preset difference threshold, the server 104 adopts the energy scheduling method of the second scheduling type to perform energy scheduling on multiple energy storage units to be scheduled: calculate the energy scheduling target of each energy storage unit to be scheduled based on the energy storage status data, and thus simultaneously perform energy scheduling on multiple energy storage units to be scheduled according to the corresponding energy scheduling target.

[0095] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0096] Based on the same inventive concept, this application also provides an energy storage unit energy dispatching device for implementing the energy dispatching method of the energy storage unit described above. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations of one or more energy storage unit energy dispatching device embodiments provided below can be found in the limitations of the energy storage unit energy dispatching method above, and will not be repeated here.
