[0022] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0024] In the operation of new energy power plants, in order to meet the business needs of different dispatchers, the power plant typically needs to connect to multiple VPPs (Virtual Power Plants). Each dispatcher can send energy dispatch instructions to the power plant through its corresponding virtual power plant platform.
[0025] In related technologies, if a power plant receives multiple energy dispatch instructions, the instructions are executed according to their chronological order. However, when receiving concurrent energy dispatch instructions from different virtual power plant platforms, there is often a lack of unified execution logic, leading to frequent switching of the power plant's operating mode and thus reducing the stability of the power plant's operation.
[0026] For example, when VPP A issues a "frequency regulation charging" command to the power station, while VPP B simultaneously issues a "spot discharge" command to the power station, the lack of coordination in the resource usage of the same power station by different virtual power plant platforms causes the power station to repeatedly switch between charging and discharging modes, thus reducing the stability of the power station's operation.
[0027] Therefore, when receiving concurrent energy dispatch instructions from different virtual power plant platforms, how to avoid concurrent conflicts between multiple energy dispatch instructions in order to improve the stability of power plant operation is a technical problem that urgently needs to be solved.
[0028] To address the aforementioned technical problems, the inventors proposed the following technical concept: creating power plant scheduling information (e.g., power plant scheduling information for the next 24 hours), and updating the power plant scheduling information based on the scheduling priority of each scheduling instruction when receiving concurrent energy scheduling instructions from different virtual power plant platforms, ensuring that higher-priority scheduling instructions can be executed first, thereby reducing the frequent switching of power plant operation modes and thus helping to improve the stability of power plant operation.
[0029] Accordingly, the specific steps may include: First, in response to receiving a first dispatch instruction from the virtual power plant platform, obtaining the dispatcher information, service type, and dispatch time period corresponding to the first dispatch instruction. Then, based on the dispatch time period, querying the power plant dispatch information to see if a second dispatch instruction has been allocated for that time period. The power plant dispatch information is used to schedule the power plant's operating mode within a preset future duration. If a second dispatch instruction has been allocated, determining the dispatch priority parameter of the first dispatch instruction based on the dispatcher information and service type corresponding to the first dispatch instruction, and determining the dispatch priority parameter of the second dispatch instruction based on the dispatcher information and service type corresponding to the second dispatch instruction. Finally, if the dispatch priority parameter of the first dispatch instruction is greater than the priority parameter of the second dispatch instruction, replacing the second dispatch instruction corresponding to the dispatch time period with the first dispatch instruction and updating the power plant dispatch information; if the dispatch priority parameter of the first dispatch instruction is less than or equal to the priority parameter of the second dispatch instruction, not updating the power plant dispatch information.
[0030] In this embodiment, when concurrent energy dispatch instructions are received from different virtual power plant platforms, the dispatch priority of each dispatch instruction can be determined according to the dispatcher information and business type corresponding to each dispatch instruction. The power plant dispatch information is updated in real time according to the dispatch priority of each dispatch instruction, ensuring that dispatch instructions with higher priority can be executed first, avoiding the power plant from executing multiple dispatch instructions at the same time, thereby reducing the frequent switching of the power plant operation mode, and thus helping to improve the stability of power plant operation.
[0031] Figure 1 This is a schematic diagram illustrating an application scenario of a method for updating power plant dispatch information provided in an embodiment of this application. For example... Figure 1 As shown, this application scenario includes a power plant 101 and multiple virtual power plant platforms 102. The connection between the power plant 101 and the virtual power plant platforms 102 can be wired or wireless. The virtual power plant platforms 102 issue scheduling instructions (e.g., "frequency regulation charging" instructions) to the power plant 101. The power plant 101 receives the scheduling instructions and, according to a power plant scheduling information update method provided in this application embodiment, updates the power plant scheduling information in real time to ensure that higher-priority scheduling instructions are executed first, avoiding the power plant from executing multiple scheduling instructions simultaneously, thereby reducing the frequent switching of power plant operating modes and thus helping to improve the stability of power plant operation.
[0032] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0033] Figure 2 This is a flowchart illustrating a method for updating power plant dispatch information provided in an embodiment of this application. Figure 2 As shown, the method may include:
[0034] S201. In response to receiving the first scheduling instruction issued by the virtual power plant platform, obtain the scheduling party information, service type and scheduling time period corresponding to the first scheduling instruction.
[0035] In this embodiment, the execution entity of the power station scheduling information update method can be the power station system, or the inverter or controller corresponding to the power station. Optionally, the power station system may include multiple distributed power stations, and each power station's inverter is equipped with a scheduling module for power station scheduling. For example, the power station may be a photovoltaic power station or other types of power station.
[0036] In this system, a single power plant can receive dispatch instructions from multiple virtual power plant platforms. However, these platforms use different message formats, requiring the maintenance of multiple message systems in existing technologies, resulting in high maintenance workload and costs.
[0037] In some embodiments, when the same power plant receives dispatch instructions from different virtual power plant platforms, the dispatch instructions with different message formats can be converted into a first dispatch instruction with a unified format. Accordingly, obtaining the dispatcher information, service type, and dispatch time period corresponding to the first dispatch instruction may include the following steps (1) to (3):
[0038] (1) Obtain the instruction source identifier carried by the first scheduling instruction.
[0039] The instruction source identifier is used to indicate the scheduler information that issued the scheduling instruction. For example, the instruction source identifier can be VPPA, VPPB, etc.
[0040] (2) Based on the instruction source identifier, obtain the target instruction parsing protocol corresponding to the first scheduling instruction from the pre-stored correspondence between instruction source identifiers and instruction parsing protocols.
[0041] Optionally, the correspondence between the instruction source identifier and the instruction parsing protocol can be stored in a key-value mapping table. Here, the instruction source identifier is the key, and the instruction parsing protocol is the value. Accordingly, this step may include: obtaining the target instruction parsing protocol corresponding to the first scheduling instruction by querying the key-value mapping table based on the instruction source identifier.
[0042] (3) Parse the first scheduling instruction through the target instruction parsing protocol to obtain the scheduling party information, service type and scheduling time period corresponding to the first scheduling instruction.
[0043] Optionally, the first scheduling instruction is parsed using a target instruction parsing protocol to obtain the scheduling instruction information corresponding to the first scheduling instruction. This scheduling instruction information may include scheduler information, service type, and scheduling time period, and may also include the scheduling target value corresponding to the service type, the priority label corresponding to the service type, and the priority label corresponding to the scheduler information. The priority label may be a priority score.
[0044] In this embodiment of the application, when receiving dispatch instructions issued by different virtual power plant platforms, the dispatch instructions of different message formats can be converted into a first dispatch instruction of a unified format by pre-storing the correspondence between the instruction source identifier and the instruction parsing protocol. This improves the parsing efficiency of dispatch instructions and also reduces the maintenance workload and maintenance cost of the message system.
[0045] S202. Based on the scheduling time period, query the power plant scheduling information to see if a second scheduling instruction has been assigned for the scheduling time period. The power plant scheduling information is used to schedule the working mode of the power plant within a preset time period in the future.
[0046] In this embodiment, the power plant scheduling information includes scheduling instructions corresponding to multiple scheduling time periods within a preset future duration, used to schedule the power plant's operating mode within the preset future duration. For example, the power plant scheduling information includes a power plant scheduling timeline for the next 24 hours.
[0047] In this embodiment, the duration of the scheduling period is not specifically limited and can be set as needed. For example, the scheduling period can be 30 minutes or 1 hour.
[0048] In some embodiments, a second scheduling instruction can be assigned to each scheduling time period by receiving scheduling instructions issued by the virtual power plant platform.
[0049] In other embodiments, scheduling instructions can be pre-allocated for each scheduling time period based on historical scheduling instructions from the virtual power plant platform. Accordingly, the step of generating initial power plant scheduling information may include: acquiring multiple historical scheduling instructions issued by the virtual power plant platform within a preset historical time period; predicting a third scheduling instruction issued by the virtual power plant platform in the target scheduling time period and the resource demand corresponding to the third scheduling instruction based on the multiple historical scheduling instructions; and if the resource demand is greater than a preset demand threshold, pre-allocating a third scheduling instruction for the target scheduling time period.
[0050] In this embodiment, the value of the preset demand threshold is not specifically limited and can be set as needed. Optionally, the preset demand threshold can be 80% of the total resources, etc.
[0051] For example, if it is predicted that VPP A will have high frequency regulation demand in the next hour, 80% of the fast charging and discharging capability will be locked and allocated to VPP A, thereby maximizing the power station's revenue.
[0052] S203. If a second scheduling instruction has been assigned, the scheduling priority parameter of the first scheduling instruction is determined based on the scheduling party information and service type corresponding to the first scheduling instruction, and the scheduling priority parameter of the second scheduling instruction is determined based on the scheduling party information and service type corresponding to the second scheduling instruction.
[0053] In some embodiments, if a second scheduling instruction has been allocated and the first scheduling instruction and the second scheduling instruction are mutually exclusive, then the scheduling priority parameter of the first scheduling instruction is determined based on the scheduling party information and service type corresponding to the first scheduling instruction, and the scheduling priority parameter of the second scheduling instruction is determined based on the scheduling party information and service type corresponding to the second scheduling instruction.
[0054] The mutual exclusion between the first scheduling instruction and the second scheduling instruction includes: the first scheduling instruction and the second scheduling instruction have different service types, or the first scheduling instruction and the second scheduling instruction have the same service type but different scheduling target values corresponding to the service types.
[0055] For example, if the first scheduling instruction is a power station charging instruction and the second scheduling instruction is a power station discharging instruction, then the first scheduling instruction and the second scheduling instruction are mutually exclusive.
[0056] In some embodiments, if a second scheduling instruction has been assigned and the first scheduling instruction is the same as the second scheduling instruction, then the power plant scheduling information is not updated.
[0057] In some embodiments, determining the scheduling priority parameter of the first scheduling instruction based on the scheduler information and service type corresponding to the first scheduling instruction includes: obtaining a first priority score corresponding to the scheduler information and a second priority score corresponding to the service type; and performing a weighted summation of the first priority score and the second priority score to obtain the scheduling priority parameter of the first scheduling instruction.
[0058] Optionally, the higher the scheduling level of the dispatcher, the higher the corresponding priority score. For example, the dispatcher information includes: a power grid platform, a primary contracting virtual power plant platform, an auxiliary contracting virtual power plant platform, and a station-side local platform. The scheduling levels are in the following order: power grid platform > primary contracting virtual power plant platform > auxiliary contracting virtual power plant platform > station-side local platform. In some examples, the priority score for the power grid platform is 100, the priority score for the primary contracting virtual power plant platform is 80, the priority score for the auxiliary contracting virtual power plant platform is 50, and the priority score for the station-side local platform is 20.
[0059] Optionally, the higher the importance of a service type, the higher its corresponding priority score. For example, service types include: fault ride-through / primary frequency regulation services, AGC (Automatic Generation Control) frequency regulation services, spot trading / peak shaving and valley filling services, and on-site self-maintenance services (such as inspection services). The order of importance is as follows: fault ride-through / primary frequency regulation services > AGC frequency regulation services > spot trading / peak shaving and valley filling services > on-site self-maintenance services. In some examples, the priority score for fault ride-through / primary frequency regulation services is 100, the priority score for AGC frequency regulation services is 80, the priority score for spot trading / peak shaving and valley filling services is 40, and the priority score for on-site self-maintenance services is 10.
[0060] In some embodiments, determining the scheduling priority parameter of the first scheduling instruction based on the scheduling party information and service type corresponding to the first scheduling instruction includes: obtaining the stability score of the power station, which is used to indicate the degree of operational stability of the power station when executing the scheduling instruction; and performing a weighted summation of the first priority score, the second priority score, and the stability score to obtain the scheduling priority parameter of the first scheduling instruction.
[0061] Optionally, the stability score of the power station can be determined based on the current operating status of the equipment. The safer the current equipment operating status and the more sufficient the execution conditions, the higher the stability score; conversely, the lower the stability score.
[0062] For example, the scheduling priority parameter of the first scheduling instruction can be expressed as: Score(A) = w1 × P source +w2×P type +w3×P safety Among them, P source P represents the first priority score. type This indicates the second priority rating, P. safety The stability score is represented by w1, w2, and w3, which represent the weights used to indicate the degree of influence of source factors, business type factors, and security factors on the overall score.
[0063] In this step, the method for determining the scheduling priority parameter of the second scheduling instruction based on the scheduling party information and service type corresponding to the second scheduling instruction is the same as the method for determining the scheduling priority parameter of the first scheduling instruction based on the scheduling party information and service type corresponding to the first scheduling instruction, and will not be described again here.
[0064] In this embodiment, a multi-dimensional weighted scoring mechanism is used to determine the scheduling priority parameters of the first scheduling instruction and the second scheduling instruction, thus clarifying the scheduling priority of each scheduling instruction. This ensures that scheduling instructions with higher priority can be executed first, avoiding the power plant from executing multiple scheduling instructions at the same time, thereby reducing the frequent switching of the power plant's operating mode and thus helping to improve the stability of the power plant's operation.
[0065] It should be noted that if no second dispatch instruction is assigned, then the first dispatch instruction will be assigned for the dispatch time period, and the power plant dispatch information will be updated.
[0066] S204. If the scheduling priority parameter of the first scheduling instruction is greater than the priority parameter of the second scheduling instruction, then the second scheduling instruction corresponding to the scheduling time period is replaced with the first scheduling instruction, and the power plant scheduling information is updated. If the scheduling priority parameter of the first scheduling instruction is less than or equal to the priority parameter of the second scheduling instruction, then the power plant scheduling information is not updated.
[0067] For example, if a first scheduling instruction (e.g., a frequency adjustment instruction for 10:00-11:00) is received from VPP A, and this scheduling time period has already been locked by a second scheduling instruction (e.g., a power plant discharge instruction) issued by VPP B, then there is a conflict between the first and second scheduling instructions. Furthermore, the scheduling priority parameter of the first scheduling instruction is greater than that of the second scheduling instruction. In this case, the second scheduling instruction corresponding to 10:00-11:00 is replaced with the first scheduling instruction, and the power plant scheduling information is updated.
[0068] It should be noted that when the upstream VPP issues dispatch instructions, it does not have real-time health status of the power plant equipment. If the power plant blindly executes the VPP's dispatch instructions (such as high-frequency frequency regulation), it may cause the power plant equipment to shut down beyond its limits.
[0069] In this embodiment of the application, the first dispatch instruction can be security verified based on the real-time status of the power plant equipment. If the verification fails, the first dispatch instruction is intercepted.
[0070] In some embodiments, before replacing the second scheduling instruction corresponding to the scheduling time period with the first scheduling instruction, the method further includes: obtaining the power scheduling parameters corresponding to the first scheduling instruction; if the power scheduling parameters are greater than or equal to a preset safe power threshold, then intercepting the first scheduling instruction; if the power scheduling parameters are less than the preset safe power threshold, then performing the step of replacing the second scheduling instruction corresponding to the scheduling time period with the first scheduling instruction; and / or, obtaining the current operating status of the power plant, determining whether the power plant meets the operating conditions for executing the first scheduling instruction based on the operating status; if not, then intercepting the first scheduling instruction; if so, then performing the step of replacing the second scheduling instruction corresponding to the scheduling time period with the first scheduling instruction.
[0071] Optionally, the current operating status of the power station includes battery temperature, individual battery voltage difference, etc. If the battery temperature is greater than a preset safe temperature threshold or the individual battery voltage difference is greater than a preset safe voltage threshold, the power station is determined not to meet the operating conditions for executing the first dispatch instruction; if the battery temperature is less than or equal to the preset temperature threshold and the individual battery voltage difference is less than or equal to the preset voltage threshold, the power station is determined to meet the operating conditions for executing the first dispatch instruction.
[0072] In this application embodiment, the values of the preset safe power threshold, preset safe temperature threshold, and preset safe voltage threshold are not specifically limited, and can be set as needed.
[0073] For example, the preset safe temperature threshold could be 45 degrees Celsius. If the battery temperature exceeds 45 degrees Celsius, it is determined that the power station does not meet the operating conditions for executing the first scheduling instruction, the first scheduling instruction is intercepted, and the reason for the execution failure is reported back to the VPP.
[0074] It should be noted that when there are a large number of scheduling instructions, urgent scheduling instructions may be blocked by other scheduling instructions. In some embodiments, a priority power plant scheduling information can be configured to handle urgent scheduling instructions. Accordingly, the method further includes: if the scheduling party information and service type corresponding to the first scheduling instruction meet the preset priority execution conditions, then the first scheduling instruction is added to the priority power plant scheduling information; wherein, the execution priority of the scheduling instructions in the priority power plant scheduling information is higher than the execution priority of the scheduling instructions in the power plant scheduling information.
[0075] For example, priority power plant dispatch information can be in a high-speed queue, while power plant dispatch information can be in a regular queue. The high-speed queue is used to process emergency dispatch commands such as primary frequency regulation commands and frequency anomaly response commands. The regular queue is used to process dispatch commands for the normal operation of each VPP (Vehicle Power Plant).
[0076] In this embodiment, if the scheduling party information and service type corresponding to the first scheduling instruction meet the preset priority execution conditions, the first scheduling instruction is added to the priority power station scheduling information, and the emergency scheduling instruction is assigned to the priority power station scheduling information to ensure that the emergency scheduling instruction is not blocked by the ordinary charging and discharging scheduling instruction, thereby improving the overall stability of the power station.
[0077] The method for updating power plant dispatch information provided in this application is as follows: In response to receiving a first dispatch instruction issued by a virtual power plant platform, the method obtains the dispatcher information, business type, and dispatch time period corresponding to the first dispatch instruction; based on the dispatch time period, it queries the power plant dispatch information to see if a second dispatch instruction has been allocated for the dispatch time period, the power plant dispatch information being used to schedule the working mode of the power plant within a preset future time period; if a second dispatch instruction has been allocated, the method determines the dispatch priority parameter of the first dispatch instruction based on the dispatcher information and business type corresponding to the first dispatch instruction, and determines the dispatch priority parameter of the second dispatch instruction based on the dispatcher information and business type corresponding to the second dispatch instruction; if the dispatch priority parameter of the first dispatch instruction is greater than the priority parameter of the second dispatch instruction, the second dispatch instruction corresponding to the dispatch time period is replaced with the first dispatch instruction, and the power plant dispatch information is updated; if the dispatch priority parameter of the first dispatch instruction is less than or equal to the priority parameter of the second dispatch instruction, the power plant dispatch information is not updated. In this embodiment, when concurrent energy dispatch instructions are received from different virtual power plant platforms, the dispatch priority of each dispatch instruction can be determined according to the dispatcher information and business type corresponding to each dispatch instruction. The power plant dispatch information is updated in real time according to the dispatch priority of each dispatch instruction, ensuring that dispatch instructions with higher priority can be executed first, avoiding the power plant from executing multiple dispatch instructions at the same time, thereby reducing the frequent switching of the power plant operation mode, and thus helping to improve the stability of power plant operation.
[0078] Figure 3 This is a schematic diagram of a power plant scheduling information updating device provided in an embodiment of this application.
