[0002] As an advanced operation mode and technology, the integration of source, grid, load and storage aims to maximize the utilization of energy resources. It significantly improves the power dynamic balance capability of the power system through various forms of interaction, such as source-source complementarity, source-grid coordination, grid-load interaction, grid-storage interaction, and source-load interaction, and provides an important development path for building a new power system. In this mode, the regulation capabilities of the power generation side and the load side are fully utilized, which promotes the precise matching of supply and demand, thereby ensuring the reliable supply of electricity.

[0003] At present, the power generation plan determination method of the source-grid-load-storage system mainly relies on the staff to make manual judgments and settings based on electricity prices and electricity demand. However, this method has the problem of low accuracy.

[0004] Therefore, it is urgent to propose a new method to solve the above problems. Summary of the invention

[0005] The present invention provides a method, device, equipment and storage medium for determining a power generation plan, which can improve the accuracy of a determined power generation plan of a source-grid-load-storage system.

[0006] In a first aspect, an embodiment of the present invention provides a method for determining a power generation plan, which is applied to a first traditional power generation node in a source-grid-load-storage system, wherein the source-grid-load-storage system further includes a second traditional power generation node, a new energy power generation node, and a central database, wherein the first traditional power generation node, the second traditional power generation node, and the new energy power generation node are respectively connected to the central database, and the method includes:

[0007] The latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node are obtained through the central database; the latest power generation plan of the new energy power generation node is determined by the new energy power generation node according to the latest power generation plan of the first traditional power generation node and the latest power generation plan of the second traditional power generation node;

[0008] Inputting the latest power generation plan of the second traditional power generation node, the latest power generation plan of the new energy power generation node, the total power generation demand and the design parameters of the first traditional power generation node into the power generation model of the first traditional power generation node, and taking the output result of the power generation model of the first traditional power generation node that meets the preset constraints as the current power generation plan of the first traditional power generation node;

[0009] Calculating a first similarity between the current power generation plan and the previous power generation plan of the first traditional power generation node;

[0010] If the first similarity is greater than a preset similarity threshold, determining the current power generation plan of the first traditional power generation node as the target power generation plan of the first traditional power generation node;

[0011] If the first similarity is not greater than the preset similarity threshold, the current power generation plan of the first traditional power generation node is uploaded to the central database, and the step of obtaining the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node through the central database is returned to execute.

[0012] The technical solution of the present invention first obtains the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node through the central database, which provides a data basis for determining the current power generation plan of the first traditional power generation node. Then, the latest power generation plan of the second traditional power generation node, the latest power generation plan of the new energy power generation node, the total power generation demand and the design parameters of the first traditional power generation node are input into the power generation model of the first traditional power generation node, and the output result of the power generation model of the first traditional power generation node that meets the preset constraints is used as the current power generation plan of the first traditional power generation node, which improves the accuracy and efficiency of the determined power generation plan, helps to achieve the power balance of the entire power generation system, and then realizes the reasonable arrangement of traditional power generation resources, thereby avoiding excessive operation or inefficient operation of equipment. In addition, the application of preset constraints ensures that the power generation plan is not only reasonable in meeting the power generation needs of the system, but also feasible in the operation of the power generation equipment itself, avoiding frequent start-up and stop of the equipment or operation in the inefficient range due to unreasonable power generation plan, extending the service life of the equipment and reducing the maintenance cost of the equipment. Then, the first similarity between the current power generation plan of the first traditional power generation node and the previous power generation plan is calculated, which provides a data basis for determining the target power generation plan of the first traditional power generation node. Determine whether the first similarity is greater than the preset similarity threshold. If it is not greater than, the current power generation plan of the first traditional power generation node will be uploaded to the central database, so that other power generation nodes (such as the second traditional power generation node) can obtain this information in a timely manner. Based on this, other nodes can adjust their own power generation plans accordingly, so that the various parts of the entire power generation system can re-achieve effective coordination and support further optimization, thereby improving the accuracy of the determined power generation plan and enhancing the flexibility of the system. If it is greater than, the current power generation plan of the first traditional power generation node will be determined as the target power generation plan of the first traditional power generation node, which improves the accuracy and stability of the target power generation plan of the first traditional power generation node, and solves the problem that the existing power generation plan determination method relies on the staff to make manual judgments and settings based on electricity prices and electricity demand, resulting in low accuracy.

[0041] Figure 1a This is a flow chart of a method for determining a power generation plan provided by an embodiment of the present invention. This embodiment is applicable to situations where a power generation plan of a source-grid-load-storage system needs to be determined. The method is applied to the first traditional power generation node in the source-grid-load-storage system. Figure 1b As shown, the source-grid-load-storage system also includes a second traditional power generation node, a new energy power generation node and a central database. The first traditional power generation node, the second traditional power generation node and the new energy power generation node are respectively connected to the central database. The method can be executed by a power generation plan determination device, which can be implemented in software and / or hardware. In a specific embodiment, the power generation plan determination device can be integrated in an electronic device, which can be a server, etc. Figure 1a The power generation plan determination method of this embodiment specifically includes the following steps:

[0042] Step 110: Obtain the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node through the central database.

[0043] Specifically, the first traditional power generation node refers to a power generation node in the source-grid-load-storage system that uses traditional power generation technology to produce electricity. For example, the first traditional power generation node can be a thermal power generation node or a storage power generation node. The second traditional power generation node also belongs to a power generation node in the source-grid-load-storage system that uses traditional power generation technology. It is similar to the first traditional power generation node, but exists as another relatively independent and distinguished traditional power generation unit in the system. The new energy power generation node refers to a node in the source-grid-load-storage system that relies on new energy (such as wind energy and solar energy) to generate electricity. The central database refers to a database system that centrally stores and manages various data (such as power generation plans and power generation requirements) in the source-grid-load-storage system. The first traditional power generation node, the second traditional power generation node, and the new energy power generation node are all connected to it and upload their respective relevant data (such as power generation plans) to it. At the same time, they can also obtain the required data information from it (such as obtaining the latest power generation plans of other nodes). It is a key hub for realizing coordinated operation and data interaction among various parts of the system. The latest power generation plan refers to the specific plan arrangement that is newly formulated for each power generation node (such as the first traditional power generation node, the second traditional power generation node and the new energy power generation node) during a specific time period to guide the power generation behavior of the node based on multiple factors such as the overall system demand and resource conditions, including key information such as power generation power and power generation period. The latest power generation plan of the new energy power generation node is determined by the new energy power generation node based on the latest power generation plan of the first traditional power generation node and the latest power generation plan of the second traditional power generation node. It should be noted that the first power generation plan of the new energy power generation node is determined by the new energy power generation node based on the new energy parameters (such as wind speed, wind direction, temperature and solar irradiance) within the preset period (the previous day).

[0044] In a specific implementation, the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node can be obtained from the central database based on the timestamp of the power generation plan.

[0045] In this embodiment, the latest power generation plans of the second traditional power generation node and the new energy power generation node are obtained through the central database, which provides a data basis for subsequently determining the current power generation plan of the first traditional power generation node.

[0046] Step 120: input the latest power generation plan of the second traditional power generation node, the latest power generation plan of the new energy power generation node, the total power generation demand and the design parameters of the first traditional power generation node into the power generation model of the first traditional power generation node, and use the output result of the power generation model of the first traditional power generation node that meets the preset constraints as the current power generation plan of the first traditional power generation node.

[0047] Specifically, the total power demand refers to the total power demand determined in advance according to the actual situation or demand. The design parameters of the first traditional power generation node refer to the key parameters that reflect the inherent characteristics and power generation capacity of the first traditional power generation node itself. For example, the design parameters of the first traditional power generation node can be the rated power and adjustable power range of the generator set. The power generation model of the first traditional power generation node refers to the power generation model trained according to the design parameters of each first traditional power generation node and its corresponding historical total power generation demand, historical constraints, historical other and own node power generation plans. It can output the power generation plan of the first traditional power generation node based on the input data (such as the power generation plan of other power generation nodes, the total power generation demand, and the design parameters of the power generation node, etc.). The preset constraints refer to the conditions and requirements that restrict the power generation plan set in advance according to the actual situation or demand. This power generation plan refers to the currently determined power generation plan.

[0048] In a specific implementation, when obtaining the latest power generation plan of the second traditional power generation node and the new energy power generation node through the central database, the total power generation demand, preset constraints and design parameters of the first traditional power generation node can also be obtained from the central database, and then the aforementioned data is input into the power generation model of the first traditional power generation node, and the initial power generation plan is output, and then it is determined whether the initial power generation plan meets the preset constraints. If it does, it is determined as the current power generation plan of the first traditional power generation node. If it does not meet the requirements, the parameters of the model can be adjusted and the power generation model can be returned to recalculate until a result that meets the preset constraints is obtained, and it is determined as the current power generation plan of the first traditional power generation node.

[0049] In this embodiment, through the above steps, the accuracy and efficiency of the determined power generation plan can be improved, which helps to achieve the power balance of the entire power generation system, and then realizes the reasonable arrangement of traditional power generation resources, thereby avoiding excessive operation or inefficient operation of equipment. In addition, the application of preset constraints ensures that the power generation plan is not only reasonable in meeting the power generation needs of the system, but also feasible in terms of the operation of the power generation equipment itself, avoiding frequent start-up and shutdown of equipment or operation in an inefficient range due to unreasonable power generation plans, extending the service life of the equipment, and reducing equipment maintenance costs.

[0050] Step 130: Calculate a first similarity between the current power generation plan and the previous power generation plan of the first traditional power generation node.

[0051] Specifically, the first similarity refers to an indicator for measuring the similarity between the current power generation plan of the first traditional power generation node and the previous power generation plan. The previous power generation plan refers to the power generation plan most recently formulated by the first traditional power generation node before the current power generation plan.

[0052] In the specific implementation, the previous power generation plan of the first traditional power generation node can be obtained from the central database, and then a suitable similarity calculation method (such as Euclidean distance, Pearson correlation coefficient, cosine similarity or dynamic time warping, etc.) can be selected according to the actual situation. Then, the selected similarity calculation method is applied to calculate the first similarity between the current power generation plan of the first traditional power generation node and the previous power generation plan.

[0053] In this embodiment, by calculating the first similarity between the current power generation plan and the previous power generation plan of the first traditional power generation node, a data basis is provided for subsequently determining the target power generation plan of the first traditional power generation node.

[0054] Step 140: Determine whether the first similarity is greater than a preset similarity threshold.

[0055] If it is greater, execute step 150 ; if it is not greater, execute step 160 .

[0056] Specifically, the preset similarity threshold refers to a similarity threshold set in advance according to actual conditions or requirements, for example, the preset similarity threshold may be 0.98.

[0057] In a specific implementation, after obtaining the first similarity, the first similarity can be compared with a preset similarity threshold to determine whether the first similarity is greater than the preset similarity threshold. If not, the current power generation plan of the first traditional power generation node is uploaded to the central database for the second traditional power generation node to determine the target power generation plan of the second traditional power generation node. If greater, the current power generation plan of the first traditional power generation node is determined as the target power generation plan of the first traditional power generation node.

[0058] Step 150: Determine the current power generation plan of the first traditional power generation node as the target power generation plan of the first traditional power generation node.

[0059] Specifically, the target power generation plan of the first traditional power generation node refers to the final power generation plan determined after similarity judgment, which will become the power generation guidance of the first traditional power generation node in the future period of time (such as one day).

[0060] In a specific implementation, after determining that the first similarity is greater than a preset similarity threshold, the current power generation plan of the first traditional power generation node is directly determined as the target power generation plan of the first traditional power generation node.

[0061] In addition, the target power generation plan of the first traditional power generation node may be uploaded to the central database for backup and used by the second traditional power generation node to determine the target power generation plan of the second traditional power generation node.

[0062] It should be noted that after determining the target power generation plan of the first traditional power generation node, it can be further confirmed whether the target power generation plans of the second traditional power generation node and the new energy power generation node have also been determined. If the target power generation plans of the above three nodes have been determined, the target power generation plans of these three nodes can be integrated to obtain the power generation plan of the source-grid-load-storage system. This power generation plan is also the scheduling plan of the source-grid-load-storage system, which covers the target power generation plans of the first traditional power generation node, the second traditional power generation node and the new energy power generation node to ensure that the power generation activities of the entire system can be carried out in an orderly and efficient manner.

[0063] In this embodiment, after determining that the first similarity is greater than the preset similarity threshold, the current power generation plan of the first traditional power generation node is determined as the target power generation plan of the first traditional power generation node, thereby improving the accuracy and stability of the determined target power generation plan of the first traditional power generation node.

[0064] Step 160: Upload the current power generation plan of the first traditional power generation node to the central database.

[0065] In a specific implementation, after determining that the first similarity is not greater than a preset similarity threshold, the current power generation plan of the first traditional power generation node is uploaded to the central database, and the process returns to step 110 .

[0066] In this embodiment, after determining that the first similarity is not greater than the preset similarity threshold, the current power generation plan of the first traditional power generation node is uploaded to the central database, so that other power generation nodes (such as the second traditional power generation node) can obtain this information in a timely manner. Based on this, other nodes can adjust their own power generation plans accordingly, so that the various parts of the entire power generation system can re-achieve effective coordination and support further optimization, thereby improving the accuracy of the determined power generation plan and enhancing system flexibility.

[0067] In the embodiment of the present invention, the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node are obtained through the central database, which provides a data basis for determining the current power generation plan of the first traditional power generation node. Then, the latest power generation plan of the second traditional power generation node, the latest power generation plan of the new energy power generation node, the total power generation demand and the design parameters of the first traditional power generation node are input into the power generation model of the first traditional power generation node, and the output result of the power generation model of the first traditional power generation node that meets the preset constraints is used as the current power generation plan of the first traditional power generation node, which improves the accuracy and efficiency of the determined power generation plan, helps to achieve the power balance of the entire power generation system, and then realizes the reasonable arrangement of traditional power generation resources, thereby avoiding excessive operation or inefficient operation of the equipment. In addition, the application of preset constraints ensures that the power generation plan is not only reasonable in meeting the power generation demand of the system, but also feasible in the operation of the power generation equipment itself, avoiding frequent start-up and stop of the equipment or operation in the inefficient range due to unreasonable power generation plan, extending the service life of the equipment and reducing the maintenance cost of the equipment. Then, the first similarity between the current power generation plan of the first traditional power generation node and the previous power generation plan is calculated, which provides a data basis for determining the target power generation plan of the first traditional power generation node. Determine whether the first similarity is greater than the preset similarity threshold. If it is not greater than, the current power generation plan of the first traditional power generation node will be uploaded to the central database, so that other power generation nodes (such as the second traditional power generation node) can obtain this information in a timely manner. Based on this, other nodes can adjust their own power generation plans accordingly, so that the various parts of the entire power generation system can re-achieve effective coordination and support further optimization, thereby improving the accuracy of the determined power generation plan and enhancing the flexibility of the system. If it is greater than, the current power generation plan of the first traditional power generation node will be determined as the target power generation plan of the first traditional power generation node, which improves the accuracy and stability of the target power generation plan of the first traditional power generation node, and solves the problem that the existing power generation plan determination method relies on the staff to make manual judgments and settings based on electricity prices and electricity demand, resulting in low accuracy.

[0068] Figure 2 A flowchart of another method for determining a power generation plan provided by an embodiment of the present invention. This embodiment is specific based on the above embodiment. In this embodiment, the method may also include:

[0069] Step 210: Obtain the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node through the central database.

[0070] Step 211, input the latest power generation plan of the second traditional power generation node, the latest power generation plan of the new energy power generation node, the total power generation demand and the design parameters of the first traditional power generation node into the power generation model of the first traditional power generation node, and use the output result of the power generation model of the first traditional power generation node that meets the preset constraints as the current power generation plan of the first traditional power generation node.

[0071] For example, if the first conventional power generation node is a thermal power generation node, the design parameters of the first conventional power generation node may be the maximum operating power of the power generation equipment, the minimum operating power of the power generation equipment, and the ramp rate of the thermal power unit, and the preset constraint condition may be P G,i,min ≤P G,i ≤P G,i,max 、|P G,i (k+1)-P G,i (k)|≤D G,i and MinC=C TH +C w / p +C s , where G is the power generation equipment, P G,i is the power of the i-th power generation equipment, P G,i,min is the minimum operating power of the ith power generation equipment, P G,i,max is the maximum operating power D of the i-th power generation equipment G,i is the power change rate of the ith power generation equipment between time periods k and k+1. C is the total cost of the source-grid-load-storage system, C TH is the operating cost of the thermal power generation node, C w / p is the operating cost of the renewable energy power generation node, C s is the operating cost of the energy storage power generation node, C TH =aP TH 2 +bP TH +c,P TH is the operating power of the thermal power unit, a, b, c are cost coefficients. w / p =c P,W / P P W / P , c P,W / P is the operating cost coefficient of renewable energy power generation, P W / P is the installed power of new energy. s =c P,E P S +c E,E E S , P S is the power of the energy storage system, E S is the capacity of the energy storage system, c P,E is the energy storage power operation cost coefficient, c E,E is the capacity operation cost coefficient.

[0072] Exemplarily, if the first traditional power generation node is an energy storage power generation node, the design parameters of the first traditional power generation node may be the power of the energy storage device, the capacity of the energy storage device, and the state of charge of the energy storage device. The preset constraint condition may be P S,i,min ≤P S,i ≤P S,i,max During charging: (P(k)T) / E < 1 - SOC, during discharging: (P(k)T) / E < SOC, and MinC = C TH +C w / p +C s where P S,i,min is the charging / discharging power of the energy storage device, P S,i is the minimum charging / discharging power of the i-th energy storage device, P S,i,max is the maximum charging / discharging power of the i-th energy storage device, P(k) is the average power in the k-th time period, T is the minimum calculation time period, E is the capacity of the energy storage, and SOC is the state of charge.

[0073] Step 212: Determine the type of the source-grid-load-storage system.

[0074] Specifically, the types of the source-grid-load-storage system include off-grid and grid-connected.

[0075] In specific implementation, determine whether the source-grid-load-storage system has an interface connected to the external power grid. If so, determine that the type of the source-grid-load-storage system is grid-connected; if not, determine that the type of the source-grid-load-storage system is off-grid.

[0076] In this embodiment, by determining the type of the source-grid-load-storage system, a data basis is provided for determining the total planned power later.

[0077] Step 213: Determine the total planned power according to the type of the source-grid-load-storage system, the power corresponding to the current power generation plan of the first traditional power generation node, the power corresponding to the latest power generation plan of the second traditional power generation node, and the power corresponding to the latest power generation plan of the new energy power generation node.

[0078] Specifically, the total planned power refers to the total planned power obtained by considering the planned power generation of all power generation nodes (including the first traditional power generation node, the second traditional power generation node, and the new energy power generation node) at a specific moment.

[0079] In specific implementation, if the type of the source-grid-load-storage system is grid-connected, determine the total planned power according to the grid power, the power corresponding to the current power generation plan of the first traditional power generation node, the power corresponding to the latest power generation plan of the second traditional power generation node, and the power corresponding to the latest power generation plan of the new energy power generation node. If the type of the source-grid-load-storage system is off-grid, determine the total planned power only according to the power corresponding to the power generation plans of each power generation node.

[0080] In this embodiment, by determining the total planned power, a data basis is provided for subsequently determining the first adjusted power generation plan of new energy.

[0081] Further, step 213 may specifically include: for the power corresponding to the current moment in the current power generation plan of the first traditional power generation node; if the type of the source, grid, load and storage system is grid-connected, then the power of the grid corresponding to the current moment, the power corresponding to the current moment in the current power generation plan of the first traditional power generation node, the power corresponding to the current moment in the latest power generation plan of the second traditional power generation node, and the power corresponding to the current moment in the latest power generation plan of the new energy power generation node are calculated, and the total planned power at the current moment is obtained; if the type of the source, grid, load and storage system is off-grid, then the power corresponding to the current moment in the current power generation plan of the first traditional power generation node, the power corresponding to the current moment in the latest power generation plan of the second traditional power generation node, and the power corresponding to the current moment in the latest power generation plan of the new energy power generation node are calculated, and the total planned power at the current moment is obtained.

[0082] For example, if the type of the source-grid-load-storage system is grid-connected, the corresponding grid power at the current moment (such as 16:30 on December 22, 2024) is 5 MW, the power corresponding to the current moment in the current power generation plan of the first traditional power generation node is 20 MW, the power corresponding to the current moment in the latest power generation plan of the second traditional power generation node is 10 MW, and the power corresponding to the current moment in the latest power generation plan of the new energy power generation node is 15 MW, then the total planned power at the current moment is 50 MW.

[0083] For example, if the type of the source-grid-load-storage system is off-grid, the power corresponding to the current moment (such as 16:30 on December 22, 2024) in the current power generation plan of the first traditional power generation node is 15 MW, the power corresponding to the current moment in the latest power generation plan of the second traditional power generation node is 18 MW, and the power corresponding to the current moment in the latest power generation plan of the new energy power generation node is 5 MW, then the total planned power at the current moment is 38 MW.

[0084] In this embodiment, through the above steps, the accuracy of the determined total planned power is improved.

[0085] Step 214: adjust the latest power generation plan of the new energy power generation node according to the total planned power and the preset target power, obtain the first adjusted power generation plan of the new energy, and upload the first adjusted power generation plan of the new energy to the central database, so that the new energy power generation node determines the latest power generation plan of the new energy power generation node according to the first adjusted power generation plan of the new energy.

[0086] Specifically, the preset target power refers to the ideal power that should be achieved at a specific time and is set in advance according to actual conditions or needs. The first adjusted power generation plan of the new energy power generation node refers to the plan obtained by adjusting the latest power generation plan of the new energy power generation node.

[0087] In a specific implementation, the latest power generation plan of the new energy power generation node can be adjusted according to the difference between the total planned power and the preset target power to obtain the first adjusted power generation plan of the new energy, and the first adjusted power generation plan of the new energy can be uploaded to the central database, so that the new energy power generation node can determine the latest power generation plan of the new energy power generation node according to the first adjusted power generation plan of the new energy. Specifically, after the new energy power generation node obtains the first adjusted power generation plan of the new energy uploaded by the first traditional power generation node and the second adjusted power generation plan of the new energy uploaded by the second traditional power generation node through the central database, it can adjust the power generation plan according to the preset cost minimization constraint (MinC = C TH +C w / p +C s ) Screen the first adjusted power generation plan of new energy and the second adjusted power generation plan of new energy, and select the new energy power generation plan corresponding to the lowest total cost as the latest power generation plan of the new energy power generation node.

[0088] In this embodiment, the above steps help adjust the new energy power generation plan, thereby reducing unnecessary energy waste and operating costs.

[0089] Furthermore, the latest power generation plan of the new energy power generation node is adjusted according to the total planned power and the preset target power to obtain a first adjusted power generation plan of new energy, including: calculating the difference between the total planned power at the current moment and the preset target power at the current moment to obtain the power difference at the current moment; if the power difference at the current moment is greater than zero, adjusting the latest power generation plan of the new energy power generation node according to the power difference at the current moment to obtain the first adjusted power generation plan of new energy.

[0090] For example, if the power generation power corresponding to the latest power generation plan of the new energy power generation node at the current moment is 20 megawatts, the total planned power is 65 megawatts, and the preset target power is set to 60 megawatts, then the power difference at the current moment is 5 megawatts. Since the power difference is greater than zero and in order to save resources, that is, not to over-generate electricity, the output of the new energy power generation node can be adjusted to make it closer to the preset target power. Then the power that the new energy power generation node needs to reduce at the current moment is 5 megawatts, so the corresponding power in the first adjusted power generation plan of new energy at the current moment is 15 megawatts. That is, the power corresponding to the latest power generation plan of the new energy power generation node at the current moment is adjusted to 15 megawatts, and the power corresponding to the rest of the time of the first adjusted power generation plan of new energy is consistent with the power corresponding to the rest of the time of the latest power generation plan of the new energy power generation node.

[0091] In this embodiment, through the above steps, the power generation power of the system can be more closely aligned with the preset target power, that is, more in line with actual power demand, thus avoiding energy waste and inefficient utilization.

[0092] Furthermore, after obtaining the power difference at the current moment, it also includes: if the power difference at the current moment is less than zero, updating the current power generation plan of the first traditional power generation node according to the power difference at the current moment.

[0093] For example, if the corresponding power generation power in the current power generation plan of the first traditional power generation node at the current moment is 20 MW, the total planned power is 65 MW, and the preset target power is set to 70 MW, then the power difference at the current moment is -5 MW. At this time, the power generation power needs to be increased, and the power generation of new energy cannot be increased artificially, so the output of the first traditional power generation node needs to be adjusted to make it closer to the preset target power. Then, the power that needs to be increased by the first traditional power generation node at the current moment is 5 MW, so the power corresponding to the current power generation plan of the first traditional power generation node at the current moment needs to be updated to 25 MW.

[0094] In this embodiment, through the above steps, it is ensured that the power generation plan can guarantee the actual electricity demand, that is, the stable and reliable supply of electricity is ensured, and the synergy and complementarity of traditional energy power generation and new energy power generation is achieved, thereby improving the comprehensive energy utilization efficiency.

[0095] Step 215: Calculate a first similarity between the current power generation plan and the previous power generation plan of the first traditional power generation node.

[0096] Step 216: Determine whether the first similarity is greater than a preset similarity threshold.

[0097] If it is greater, execute step 217; if it is not greater, execute step 218.

[0098] Step 217: Determine the current power generation plan of the first traditional power generation node as the target power generation plan of the first traditional power generation node.

[0099] Step 218: Upload the current power generation plan of the first traditional power generation node to the central database.

[0100] Furthermore, when the first traditional power generation node is a thermal power generation node and the second traditional power generation node is an energy storage power generation node, the power generation plan determination method of this embodiment also includes: determining the type of the source-grid-load-storage system; if the type of the source-grid-load-storage system is off-grid, determining the frequency of the source-grid-load-storage system according to the pole pair number and rated speed of the engine of the thermal power generation node, and uploading the frequency of the source-grid-load-storage system to the central database.

[0101] Specifically, a thermal power generation node refers to a node that generates electricity using a thermal power unit (including boilers, steam turbines, generators, etc.). An energy storage generation node refers to a node that generates electricity using energy storage equipment (such as batteries, energy storage power stations, etc.). Frequency refers to the number of times the alternating current completes a periodic change per unit time, and the unit is Hertz (Hz). The number of pole pairs of the engine refers to the number of magnetic pole pairs of the motor's magnetic field. The rated speed refers to the speed at which the engine can operate stably for a long time under the designed operating conditions.

[0102] In a specific implementation, the type of the source-grid-load-storage system can be determined according to the method of step 212. If the type of the source-grid-load-storage system is off-grid, the frequency of the source-grid-load-storage system is determined according to the pole pair number and rated speed of the engine of the thermal power generation node, and the frequency of the source-grid-load-storage system is uploaded to the central database. Specifically, the frequency of the source-grid-load-storage system = the pole pair number of the engine of the thermal power generation node × rated speed / 60. If the type of the source-grid-load-storage system is grid-connected, the frequency of the source-grid-load-storage system can be kept consistent with the frequency of the connected external power grid.

[0103] In this embodiment, the above steps ensure the stable operation of the off-grid source-grid-load-storage system.

[0104] Furthermore, after uploading the frequency of the source-grid-load-storage system to the central database, it also includes: obtaining the real-time frequency of the source-grid-load-storage system, and uploading the real-time frequency to the central database; if the real-time frequency is not within the preset frequency range, adjusting the power generation power and load of the thermal power generation node according to the real-time frequency.

[0105] Specifically, the preset frequency range refers to the range of allowable fluctuations in the source-grid-load-storage system frequency set in advance according to actual conditions or needs. For example, the preset frequency range can be 49.5Hz to 50.5Hz. The real-time frequency refers to the frequency value actually measured at a certain moment in the actual operation of the source-grid-load-storage system. The load refers to the total power consumed by all electrical equipment.

[0106] In the specific implementation, the real-time frequency can be obtained through the frequency sensor and uploaded to the central database, and then it is determined whether the real-time frequency is within the preset frequency range. If the real-time frequency is not within the preset frequency range, the power generation and load of the thermal power generation node are adjusted according to the real-time frequency. Specifically, if the real-time frequency is lower than the lower limit of the preset range, the power generation of the thermal power generation node can be increased to provide more power to restore the frequency. At the same time, the power supply of some non-critical loads can be reduced to assist in restoring the frequency. If the real-time frequency is higher than the upper limit of the preset range, the power generation of the thermal power generation node is reduced to reduce power output. At the same time, the power supply of some loads can be increased to consume excess power, thereby helping to reduce the frequency.

[0107] In this embodiment, the above steps are used to ensure that the frequency is maintained within the normal range, thereby ensuring the normal operation of electrical equipment and avoiding equipment performance degradation, damage, or even power outages due to frequency abnormalities.

[0108] Therefore, the technical solution of the present invention obtains the latest power generation plan of the second traditional power generation node and the latest power generation plan of the new energy power generation node through the central database, which provides a data basis for determining the current power generation plan of the first traditional power generation node. Then the latest power generation plan of the second traditional power generation node, the latest power generation plan of the new energy power generation node, the total power generation demand and the design parameters of the first traditional power generation node are input into the power generation model of the first traditional power generation node, and the output result of the power generation model of the first traditional power generation node that meets the preset constraints is used as the current power generation plan of the first traditional power generation node, which improves the accuracy and efficiency of the determined power generation plan, helps to achieve the power balance of the entire power generation system, and then realizes the reasonable arrangement of traditional power generation resources, thereby avoiding excessive or inefficient operation of equipment. In addition, the application of preset constraints ensures that the power generation plan is not only reasonable in meeting the power generation needs of the system, but also feasible in the operation of the power generation equipment itself, avoiding frequent start-up and shutdown of equipment or operation in an inefficient range due to unreasonable power generation plans, extending the service life of the equipment and reducing the maintenance cost of the equipment. Then, the type of the source-grid-load-storage system is determined, which provides a data basis for determining the total planned power. The total planned power is determined according to the type of source-grid-load-storage system, the power corresponding to the current power generation plan of the first traditional power generation node, the power corresponding to the latest power generation plan of the second traditional power generation node, and the power corresponding to the latest power generation plan of the new energy power generation node, which provides a data basis for determining the first adjusted power generation plan of the new energy later. The latest power generation plan of the new energy power generation node is adjusted according to the total planned power and the preset target power to obtain the first adjusted power generation plan of the new energy, and the first adjusted power generation plan of the new energy is uploaded to the central database, so that the new energy power generation node determines the latest power generation plan of the new energy power generation node according to the first adjusted power generation plan of the new energy, which helps to adjust the new energy power generation plan, thereby reducing unnecessary energy waste and operating costs. The first similarity between the current power generation plan of the first traditional power generation node and the previous power generation plan is calculated, which provides a data basis for determining the target power generation plan of the first traditional power generation node later. Determine whether the first similarity is greater than the preset similarity threshold. If not, the current power generation plan of the first traditional power generation node is uploaded to the central database, so that other power generation nodes (such as the second traditional power generation node) can obtain this information in a timely manner. Based on this, other nodes can adjust their own power generation plans accordingly, so that the various parts of the entire power generation system can re-achieve effective coordination and support further optimization, thereby improving the accuracy of the determined power generation plan and enhancing the flexibility of the system. If it is greater than, the current power generation plan of the first traditional power generation node is determined as the target power generation plan of the first traditional power generation node, which improves the accuracy and stability of the target power generation plan of the first traditional power generation node, and solves the problem of low accuracy of the existing power generation plan determination method due to reliance on manual judgment and setting by staff based on electricity prices and power demand.
