[0002] In related technologies, with the rapid planning and construction of new power systems, new energy sources, represented by wind power and photovoltaic power, are gradually becoming an important part of my country's power energy. For power plants, wind power and photovoltaic power are characterized by randomness, volatility, and instability, and are easily affected by environmental factors.

[0003] However, for power plants, there is an objectively defined electricity demand as their power generation target. If they rely solely on wind and solar power, fluctuations in demand will make it difficult for them to guarantee achieving their power generation target.

[0004] Therefore, how to optimize the power generation of wind and solar power equipment through reasonable scheduling, based on the existing use of batteries, storage stations and other power equipment, to achieve efficient power resource scheduling and meet power generation targets, is an urgent problem to be solved. Summary of the Invention

[0005] The main purpose of this application is to provide a power resource dispatching method, equipment, storage medium and product, which aims to solve the technical problem of how to efficiently dispatch power resources among wind and solar equipment, batteries and power storage stations.

[0006] To achieve the above objectives, this application proposes a power resource dispatching method, which includes: Obtain the electricity demand value, the maximum total power generation of wind power equipment and photovoltaic equipment, the charging power range of batteries, the discharging power range of batteries, the power generation range of storage stations, and the energy storage range. When the maximum total power generation is less than the power demand, the first target power generation of the power station and the first target charging and discharging strategy of the battery are calculated based on the first difference, the discharge power range, and the power generation range; the first difference is the difference between the maximum total power generation and the power demand. Control the power station to generate electricity at the first target power output, and control the battery to charge or discharge according to the first target charging and discharging strategy; When the maximum total power generation exceeds the power demand, the second target charging and discharging strategy of the battery, the target energy storage power of the power station, and the second target power generation of the wind power equipment are calculated based on the first difference, the charging power range, and the energy storage power range. Control the wind power equipment to generate electricity at the second target power output, control the battery to charge or discharge according to the second target charging and discharging strategy, and control the energy storage station to store electricity at the target energy storage power.

[0007] In some embodiments, when the maximum total power generation is less than the power demand, a first target power generation of the power storage station and a first target charging and discharging strategy of the battery are calculated based on a first difference, a discharge power range, and a power generation range, including: If the first difference is greater than a preset threshold and the first difference is greater than or equal to a first value, the first target power generation is determined to be the maximum value of the power generation range, and the first target charging and discharging strategy is to discharge according to the maximum value of the discharge power range; the first value represents the sum of the maximum value of the discharge power range and the maximum value of the power generation range.

[0008] In some embodiments, when the maximum total power generation is less than the power demand, a first target power generation of the power storage station and a first target charging and discharging strategy of the battery are calculated based on a first difference, a discharge power range, and a power generation range, including: If the first difference is greater than a preset threshold, and the first difference is less than a first value, and the first difference is less than the minimum value of the power generation range, then the first target power generation is determined to be the minimum value of the power generation range, and the first target charging and discharging strategy is determined to be charging according to the second difference, wherein the second difference is the difference between the first difference and the minimum value of the power generation range.

[0009] In some embodiments, when the maximum total power generation is less than the power demand, a first target power generation of the power storage station and a first target charging and discharging strategy of the battery are calculated based on a first difference, a discharge power range, and a power generation range, including: If the first difference is greater than a preset threshold and less than a first value, and if the first difference is within the range of power generation, the first target power generation is determined to be equal to the first difference, and the first target charging and discharging strategy is determined to be no charging and discharging. If the first difference is greater than the maximum value of the power generation range, the first target power generation is determined to be the maximum value of the power generation range, and the first target charging and discharging strategy is determined to be charging according to the third difference, where the third difference is the difference between the first difference and the maximum value of the power generation range.

[0010] In some embodiments, when the maximum total power generation exceeds the power demand, a second target charging and discharging strategy for the battery, a target energy storage capacity for the power station, and a second target power generation capacity for the wind power equipment are calculated based on a first difference, a charging power range, and a storage power range, including: If the first difference is greater than a preset threshold and the first difference is greater than a second value, the second target charging / discharging strategy is determined to be charging according to the maximum value of the charging power range. The target energy storage capacity is determined by storing energy according to the maximum value within the energy storage capacity range, and The second target power generation is determined as the difference between the power demand value and the total energy storage value, where the total energy storage value is the sum of the maximum value of the energy storage power range and the maximum value of the charging power range; the second value represents the sum of the maximum value of the charging power range and the maximum value of the energy storage power range.

[0011] In some embodiments, when the maximum total power generation exceeds the power demand, a second target charging and discharging strategy for the battery, a target energy storage capacity for the power station, and a second target power generation capacity for the wind power equipment are calculated based on a first difference, a charging power range, and a storage power range, including: If the first difference is greater than a preset threshold, and the first difference is less than or equal to a second value, and the first difference is less than the minimum value of the energy storage power range, then the target energy storage efficiency is determined to be based on storing energy according to the minimum value of the energy storage power range. The second target charging and discharging strategy is determined to be discharging according to the fourth difference, where the fourth difference is the difference between the minimum value of the energy storage power range and the first difference, and The second target power generation capacity is determined to be the maximum total power generation capacity.

[0012] In some embodiments, when the maximum total power generation exceeds the power demand, a second target charging and discharging strategy for the battery, a target energy storage capacity for the power station, and a second target power generation capacity for the wind power equipment are calculated based on a first difference, a charging power range, and a storage power range, including: If the first difference is greater than a preset threshold and the first difference is less than or equal to the second value, and if the first difference is within the range of energy storage power, the target energy storage efficiency is determined to be equal to the first difference, the second target charging and discharging strategy is determined to be no charging and discharging, and the second target power generation is determined to be the maximum total power generation. If the first difference is greater than the maximum value of the energy storage power range, the target energy storage efficiency is determined to be the maximum value of the energy storage power range, the second target charging and discharging strategy is determined to be the fourth difference, and the second target power generation is determined to be the maximum total power generation; wherein, the fourth difference is the difference between the first difference and the maximum value of the energy storage power range.

[0013] In addition, to achieve the above objectives, this application also proposes a power resource dispatching device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program is configured to implement the steps of the power resource dispatching method described above.

[0014] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the power resource scheduling method described above.

[0015] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the power resource scheduling method described above.

[0016] One or more technical solutions proposed in this application have at least the following technical effects: When generating electricity using wind and solar power equipment, if the maximum combined power output of these two systems is less than the electricity demand, it indicates a power generation gap. By considering this gap, the battery's discharge power range, and the power output range of the power storage station, the first target power output of the power storage station and the first target charge / discharge power of the battery are calculated. This allows the power storage station to generate electricity at the first target power output, supplemented by the battery charging or discharging using the first target charge / discharge strategy. When a power generation gap exists, efforts are made to fill it, ensuring that the overall power generation is close to the electricity demand and meets the power generation requirements.

[0017] When the maximum combined power generation of wind and solar power equipment is greater than or equal to the power demand, it indicates that power generation has overflowed. By using the first difference (i.e., the overflow amount), the charging power range of the battery, and the energy storage power range of the power storage station, the second target power generation of the wind and solar power equipment, the target energy storage power of the power storage station, and the second target charging and discharging strategy of the battery are calculated. The wind and solar power equipment are controlled to adjust their power generation to the second target power generation, and the power storage station is used to store energy at the target energy storage power, and the battery is charged or discharged according to the second target charging and discharging strategy. This helps to avoid over-generation and store the overflow of electricity, thus avoiding the waste of power resources.

[0018] In both of these situations, by fully coordinating different power equipment, the overall power generation can meet the power demand as much as possible when charging is insufficient, while avoiding excessive power generation and waste when charging is in surplus, thus achieving efficient allocation of power resources.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0024] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The main solution of this application embodiment is as follows: Obtain the power demand value, the maximum total power generation of wind power equipment and photovoltaic equipment, the charging power range of the battery, the discharging power range of the battery, the power generation range of the storage station, and the energy storage range; when the maximum total power generation is less than the power demand value, calculate the first target power generation of the storage station and the first target charging / discharging strategy of the battery based on the first difference, the discharging power range, and the power generation range; the first difference is the difference between the maximum total power generation and the power demand value; control the storage station to generate power at the first target power generation, and control the battery to charge or discharge using the first target charging / discharging strategy; when the maximum total power generation is greater than the power demand value, calculate the second target charging / discharging strategy of the battery, the target energy storage power of the storage station, and the second target power generation of the wind power equipment based on the first difference, the charging power range, and the energy storage range; control the wind power equipment to generate power at the second target power generation, control the battery to charge or discharge using the second target charging / discharging strategy, and control the storage station to store energy at the target energy storage power.

[0026] In related technologies, with the rapid planning and construction of new power systems, new energy sources, represented by wind power and photovoltaic power, are gradually becoming an important part of my country's power energy. For power plants, wind power and photovoltaic power are characterized by randomness, volatility, and instability, and are easily affected by environmental factors.

[0027] However, for power plants, there is an objectively defined electricity demand as their power generation target. If they rely solely on wind and solar power, fluctuations in demand will make it difficult for them to guarantee achieving their power generation target.

[0028] Therefore, how to optimize the power generation of wind and solar power equipment through reasonable scheduling, based on the existing use of batteries, storage stations and other power equipment, to achieve efficient power resource scheduling and meet power generation targets, is an urgent problem to be solved.

[0029] Based on this, this application provides a solution that uses electrochemical energy storage and pumped hydro storage as means of regulating wind and solar power, and makes timely decisions on charging / pumping and discharging / generating power according to different operating conditions, thereby achieving efficient scheduling of wind, solar and energy storage and achieving better power distribution performance.

[0030] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or a power resource dispatching device capable of performing the above functions. The following description uses a power resource dispatching device as an example to illustrate this embodiment and the subsequent embodiments.

[0031] Reference Figure 1 , Figure 1 An embodiment of the power resource dispatching method provided in this application is illustrated. The power resource dispatching method can be applied to power resource dispatching equipment and includes the following steps S110 to S150: Step S110: Obtain the power demand value, the maximum total power generation of wind power equipment and photovoltaic equipment, the charging power range of batteries, the discharging power range of batteries, the power generation range of the power storage station, and the energy storage range.

[0032] Among them, the electricity demand value refers to the active power plan curve value issued by the power grid dispatching and management department, which can be approximately understood as the power generation required by the power grid dispatching and management department.

[0033] Wind power equipment refers to wind turbine generators, and photovoltaic (PV) equipment refers to photovoltaic (PV) generators. Wind turbine generators generate electricity based on wind power, while PV generators generate electricity based on sunlight; both are characterized by their variable power output depending on environmental conditions. Therefore, in this embodiment, the maximum power output of the wind turbine generator (hereinafter referred to as [specific power output]) can be adjusted according to the current environmental conditions. The prediction of the minimum power generation (referred to as a proxy) and the maximum power generation of photovoltaic power generation equipment (hereinafter referred to as a proxy) is performed. (Referring to) and minimum power generation are used for prediction.

[0034] It is understandable that the maximum combined power generation capacity of wind power equipment and photovoltaic equipment is... and sum.

[0035] A battery refers to an electrochemical energy storage device. It can be understood that a battery can be charged and discharged. In some implementations, the charging power range and discharging power range can be calculated based on the current operating conditions of the battery, including the maximum charging power, minimum charging power, maximum discharging power, and minimum discharging power.

[0036] Storage power stations are similar to batteries, but they generally use hydropower. In some implementations, the power generation range and energy storage range of the storage power station can be calculated based on its current operating conditions. The power generation range can include the maximum power generation and the minimum power generation, and the energy storage range can include the maximum energy storage capacity and the minimum energy storage capacity.

[0037] Step S120: When the maximum total power generation is less than the power demand, the first target power generation of the power station and the first target charging and discharging strategy of the battery are calculated based on the first difference, the discharge power range and the power generation range.

[0038] In step S130, the power station is controlled to generate electricity at the first target power output, and the battery is controlled to charge or discharge according to the first target charging and discharging strategy.

[0039] The first difference is the difference between the maximum total power generation and the power demand.

[0040] Specifically, the relationship between the maximum total power generation and the power demand can be calculated, and the first difference between them can be determined. : .

[0041] In some implementations, a preset threshold can be defined in advance. Preset threshold Used to characterize the critical value that allows for the non-dispatch of batteries and storage stations, when the first difference... Exceeding the preset threshold At that time, batteries and power stations must be used for power generation / discharge; when the first difference... Not exceeding the preset threshold In this case, the first difference can be ignored, and only wind power equipment and photovoltaic equipment can be used for power generation.

[0042] In some implementations, if Then the wind power equipment and photovoltaic equipment generate electricity at their respective maximum power, that is, the power generation capacity of the wind power equipment is The power generation capacity of the photovoltaic equipment is .

[0043] if If the condition is not met, meaning the first difference exceeds the preset threshold, then it is necessary to further determine the first target power generation of the power station and the first target charging and discharging strategy of the battery based on the first difference, the discharge power range, and the power generation range.

[0044] There are two situations: (1) The first difference is greater than or equal to the first value (the sum of the maximum value of the discharge power range and the maximum value of the power generation range), that is : In this situation, even if the power station and the battery operate at their respective maximum power, it is still impossible to make up for the gap in the first difference. In order to make up for this gap as much as possible, the first target power generation is determined to be the maximum value of the power generation range, and the first target charging and discharging strategy is to discharge according to the maximum value of the discharge power range.

[0045] (2) The first difference is less than the first value: In this case, it is further divided into the following sub-cases AC: A: The first difference is less than the minimum value of the power generation range, that is... If the first target power generation is determined to be the minimum value of the power generation range, then even if the power station generates power at the minimum power, it is sufficient to make up for the gap of the first difference, and there is still a surplus. Therefore, the first target charging and discharging strategy is determined to be charging according to the second difference, where the second difference is the difference between the first difference and the minimum value of the power generation range, so as to store the surplus and avoid waste.

[0046] B: If the first difference is within the range of power generation, then the power station can make up for the gap of the first difference by itself, and the battery does not need to be operated. Therefore, it can be directly determined that the first target power generation is equal to the first difference, and the first target charging and discharging strategy is to not charge and discharge.

[0047] C: If the first difference is greater than the maximum value of the power generation range, it is determined that the power station alone cannot make up for the gap in the first difference, but the battery can. Therefore, the power station can be set to discharge at its maximum power, and the remaining gap can be made up by the battery. That is, the first target power generation is determined to be the maximum value of the power generation range, and the first target charging and discharging strategy is determined to be charging according to the third difference, where the third difference is the difference between the first difference and the maximum value of the power generation range.

[0048] Step S140: When the maximum total power generation is greater than the power demand, the second target charging and discharging strategy of the battery, the target energy storage power of the power station, and the second target power generation of the wind power equipment are calculated based on the first difference, the charging power range, and the energy storage power range.

[0049] In step S150, the wind power equipment is controlled to generate electricity at the second target power, the battery is controlled to charge or discharge according to the second target charging and discharging strategy, and the energy storage station is controlled to store electricity at the target energy storage power.

[0050] Understandably, a maximum total generating capacity exceeding the electricity demand means that wind and solar power equipment will inevitably generate a surplus of electricity if they operate at their maximum total generating capacity. To avoid wasting this surplus electricity, the following steps are used for dispatching.

[0051] (3) The first difference is greater than the second value (the sum of the maximum value of the charging power range and the maximum value of the energy storage power range). In other words, even if the power station and battery absorb energy at their respective maximum charging power, they cannot consume the surplus of the first difference. Therefore, to avoid waste, the second target charging and discharging strategy can be determined as charging at the maximum value of the charging power range, the target energy storage power can be determined as storing energy at the maximum value of the energy storage power range, and the second target power generation power can be determined as the difference between the power demand value and the total energy storage value, where the total energy storage value is the sum of the maximum value of the energy storage power range and the maximum value of the charging power range. Simply put, this means that the power station and battery each store energy at their maximum power, while the wind power equipment and photovoltaic equipment reduce their corresponding power generation power proportionally to avoid wasting power generation.

[0052] (4) If the first difference is less than the second value, similar to step S120 above, it can be divided into the following sub-cases DF: D: The first difference is less than the minimum value of the energy storage power range. Although there is an overflow in power generation, the overflow is very small and not enough to reach the minimum value of the energy storage power range. At this point, a small gap is created, which can be filled by the battery. That is, the target energy storage efficiency can be determined as storing energy according to the minimum value of the energy storage power range, and the second target charging and discharging strategy can be determined as discharging according to the fourth difference, where the fourth difference is the difference between the minimum value of the energy storage power range and the first difference, and the second target power generation is determined as the maximum total power generation. Simply put, the power station stores energy according to the minimum energy storage power, and the gap is filled by the battery generating electricity.

[0053] E: If the first difference is within the range of energy storage capacity, it means that the power station can absorb this overflow power on its own, and the battery does not need to perform any operation. That is, the target energy storage efficiency is determined to be equal to the first difference, the second target charging and discharging strategy is determined to be no charging and discharging, and the second target power generation is determined to be the maximum total power generation.

[0054] F: If the first difference is greater than the maximum value of the energy storage power range, it means that the power station cannot absorb the overflow power on its own and the batteries need to work together to absorb it. That is, the target energy storage efficiency is determined to be the maximum value of the energy storage power range, the second target charging and discharging strategy is determined to be the fourth difference, and the second target power generation is determined to be the maximum total power generation; where the fourth difference is the difference between the first difference and the maximum value of the energy storage power range.

[0055] In summary, for ease of understanding, the cases AF in steps S120 to S130 above can be understood through... Figure 2 The flowchart in the diagram is used to represent this.

[0056] in, Figure 2 In this context, "wind and solar" refers to the wind power equipment and photovoltaic equipment in the aforementioned embodiments; "battery energy storage" refers to the battery in the aforementioned embodiments; and "meeting accuracy requirements" means exceeding the preset threshold in the aforementioned embodiments.

[0057] This embodiment provides a power resource scheduling method. Power is generated using wind and solar power equipment. If the maximum combined power output of the wind and solar power equipment is less than the power demand, it indicates a power generation gap. Using a first difference (i.e., the power generation gap), the battery's discharge power range, and the power generation range of the power storage station, a first target power output of the power storage station and a first target charge / discharge power of the battery are calculated. This allows the power storage station to generate power at the first target power output, supplemented by the battery charging or discharging using the first target charge / discharge strategy. When a power generation gap exists, it is filled as much as possible, making the overall power generation close to the power demand and meeting the power generation requirements.

[0058] When the maximum combined power generation of wind and solar power equipment is greater than or equal to the power demand, it indicates that power generation has overflowed. By using the first difference (i.e., the overflow amount), the charging power range of the battery, and the energy storage power range of the power storage station, the second target power generation of the wind and solar power equipment, the target energy storage power of the power storage station, and the second target charging and discharging strategy of the battery are calculated. The wind and solar power equipment are controlled to adjust their power generation to the second target power generation, and the power storage station is used to store energy at the target energy storage power, and the battery is charged or discharged according to the second target charging and discharging strategy. This helps to avoid over-generation and store the overflow of electricity, thus avoiding the waste of power resources.

[0059] In both of these situations, by fully coordinating different power equipment, the overall power generation can meet the power demand as much as possible when charging is insufficient, while avoiding excessive power generation and waste when charging is in surplus, thus achieving efficient allocation of power resources.

[0060] This application provides a power resource scheduling device, which includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform the power resource scheduling method in the above embodiment 1.
