[0023] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0024] The embodiment of the present application provides a distribution network dispatching method, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102 and step S103, wherein: Step S101: Acquire real-time load data, auxiliary prediction data and historical demand data of the distribution network, perform load prediction based on the historical demand data, real-time load data and auxiliary prediction data, and determine load prediction information.

[0025] For the embodiment of the present application, in the process of power dispatching of the distribution network, load forecasting is an important prerequisite for power system planning, which helps the power department to reasonably arrange power generation plans, optimize resource allocation, and improve the stability and safety of power supply of the power grid. Therefore, the real-time load data of the distribution network is obtained, and the real-time load data reflects the current operating status and power demand of the distribution network, which can not only timely discover abnormal changes in power demand, but also provide important data basis for load forecasting. However, in the actual power consumption process, many factors will affect the power demand, such as meteorological factors, holiday factors, activity factors, economic factors, etc. The various factors that affect the power demand are recorded as auxiliary forecasting data, which helps to fully understand the changing laws and influencing factors of power demand, thereby improving the accuracy and reliability of load forecasting. At the same time, the historical demand data is the load power consumption data of the distribution network in the past period of time. The historical demand data is an important basis for load forecasting. By analyzing the historical demand data, the long-term change trend and seasonal characteristics of power demand can be grasped, providing an important reference basis for load forecasting.

[0026] Furthermore, load forecasting is performed based on historical demand data, real-time load data and auxiliary forecasting data to determine load forecasting information. The load forecasting information characterizes the demand for power load in a future period of time, including but not limited to: total load, peak load, load curve, load growth rate and load volatility in the forecasting period. There are many ways to forecast load, and the embodiments of the present application are no longer limited. In one achievable method, data integration is performed based on historical demand data, real-time load data and auxiliary forecasting data to obtain target demand data; a first feature extraction is performed based on the target demand data to determine linear features and seasonal features, and demand forecasting is performed based on the linear features and seasonal features to determine the first load forecasting information; a second feature extraction is performed based on the target demand data to determine nonlinear features, and demand forecasting is performed based on the nonlinear features to determine the second load forecasting information; combined forecasting is performed based on the first load forecasting information and the second load forecasting information to determine the load forecasting information. In the process of executing load forecasting, the linear features, nonlinear features and seasonal features of the power demand data are comprehensively considered, and a method of combining multiple models for forecasting is used to perform load forecasting, thereby improving the accuracy of load forecasting.

[0027] Step S102: Obtain a power generation plan corresponding to each power resource in the distribution network, perform supply and demand analysis based on each power generation plan and load forecast information, and determine a supply and demand analysis result.

[0028] For the embodiments of the present application, the demand for electricity in the distribution network will be affected by many factors. As the demand for electricity continues to increase, there may be an imbalance in the supply and demand of electricity. In order to ensure the stable operation of the power system and avoid economic losses caused by power outages or excess power, performing supply and demand analysis of electricity will help improve the reliability of power supply and ensure the stable operation of the power system during peak hours or in emergency situations.

[0029] Specifically, the power generation plan corresponding to each power resource in the distribution network is obtained. The power generation plan should include the expected power generation in each time period (for example, hour, day, week, month), and supply and demand analysis is performed based on each power generation plan and load forecast information to determine the supply and demand analysis results. There are many specific implementation methods for supply and demand analysis, and the embodiments of the present application are no longer limited. In one achievable method, the power supply calculation is performed based on each power generation plan to determine the power supply information; based on the power supply information and the load forecast information supply and demand analysis, the supply and demand analysis results are determined, wherein the supply and demand analysis results include: oversupply, undersupply and supply and demand balance. In another achievable method, a supply and demand analysis model is established based on the power generation plan and load forecast information, and the supply and demand analysis model can reflect the supply and demand situation in each time period and each region in the power system. In the supply and demand analysis model, the power supply and demand in each time period and each region are calculated, the power supply and demand are compared, and the supply and demand balance state is determined, that is, oversupply, undersupply or supply and demand balance.

[0030] Step S103: When the supply and demand analysis result is that supply exceeds demand, an optimization scheduling analysis is performed based on each power generation plan and load forecast information, emergency scheduling information is determined, and the emergency scheduling information is sent to the target power resources to control the target power resources to perform power scheduling according to the emergency scheduling information.

[0031] For the embodiment of the present application, when the supply and demand analysis result is that the supply is insufficient to meet the demand, it indicates that the power supply of the power system cannot meet the demand side's usage requirements. Therefore, based on each power generation plan and load forecast information, an optimized scheduling analysis is performed to determine the emergency scheduling information. The formulation and implementation of the emergency scheduling information helps to optimize the configuration of power resources, avoid power outages caused by insufficient power supply, and improve the emergency response capability of the power system, so that it can respond to various emergencies in a short time, and improve the quality and stability of power supply. There are many specific implementation methods for optimized scheduling analysis, which are no longer limited in the embodiment of the present application. In one achievable method, the scheduling constraint conditions are obtained, and based on the scheduling constraint conditions, each power resource is prioritized to determine the power resource scheduling sequence; the power resource information corresponding to each power resource in the distribution network is obtained, and the incremental power analysis is performed based on each power resource information and the power generation plan to determine the additional power corresponding to each power resource; the optimized scheduling analysis is performed based on the power resource scheduling sequence and the additional power corresponding to each power resource to determine the emergency scheduling information.

[0032] When the supply and demand analysis result shows that supply exceeds demand, it usually means that there is an oversupply of electricity, and it is necessary to adjust the power generation plan, reduce unnecessary power generation, or consider storing or selling excess electricity to other areas with demand. When the supply and demand analysis result shows that supply and demand are balanced, it indicates that the power supply is in a stable state. We should continuously monitor changes in supply and demand to ensure the stable operation of the power system.

[0033] It can be seen that in the embodiment of the present application, the real-time load data, auxiliary prediction data and historical demand data of the distribution network are obtained, and the load prediction is performed based on the historical demand data, the real-time load data and the auxiliary prediction data to determine the load prediction information. The load prediction helps the power department to reasonably arrange the power generation plan, optimize the resource allocation, and improve the stability and safety of the power supply of the power grid. Then, the power generation plan corresponding to each power resource in the distribution network is obtained, and the supply and demand analysis is performed based on each power generation plan and load prediction information to determine the supply and demand analysis results, and the supply and demand analysis of electric energy is performed, which helps to improve the reliability of power supply and ensure the stable operation of the power system during peak hours or in emergency situations. When the supply and demand analysis result is that the supply is insufficient to meet the demand, the optimization scheduling analysis is performed based on each power generation plan and load prediction information to determine the emergency scheduling information, and the emergency scheduling information is sent to the target power resource, and the target power resource is controlled to perform power scheduling according to the emergency scheduling information. The formulation and implementation of emergency scheduling information helps to optimize the configuration of power resources, avoid power outages caused by insufficient power supply, and improve the emergency response capability of the power system, so that it can respond to various emergencies in a short time, and improve the quality and stability of power supply.

[0034] Furthermore, in order to select appropriate power generation resources and optimize the configuration of power resources during the scheduling process, in the embodiment of the present application, an optimization scheduling analysis is performed based on each power generation plan and load forecast information to determine the emergency scheduling information, including: Obtain scheduling constraints, prioritize each power resource based on the scheduling constraints, and determine the power resource scheduling sequence; Obtain the power resource information corresponding to each power resource in the distribution network, perform incremental power analysis based on each power resource information and the power generation plan, and determine the additional power corresponding to each power resource; Based on the power resource dispatch sequence and the additional power corresponding to each power resource, an optimized dispatch analysis is performed to determine the emergency dispatch information.

[0035] For the embodiment of the present application, in the power system of the distribution network, there are different types of power generation resources, such as wind power generation, solar power generation, fossil energy power generation, etc. Different power generation resources have different power generation characteristics and cost-effectiveness. Therefore, each power resource is prioritized according to the scheduling constraints to facilitate the selection of appropriate power generation resources during the scheduling process and optimize the configuration of power resources.

[0036] Specifically, the dispatch constraint condition is obtained, which is a dispatch constraint condition determined by the dispatch management personnel based on multiple factors such as the area where the distribution network is located and the time period where the dispatch is located, for example, minimizing the cost of power generation, maximizing the efficiency of energy utilization, and reducing greenhouse gas emissions. Of course, the corresponding dispatch constraint condition can also be set according to the actual situation. Then, based on the power generation characteristics and dispatch constraint conditions of each power resource, each power resource is prioritized to determine the power resource dispatch sequence, wherein the power resource that is closer to the dispatch constraint condition is closer to the front position. At the same time, the power resource information corresponding to each power resource in the distribution network is obtained, and the power resource information includes but is not limited to: installed capacity, power generation type, power generation efficiency, equipment status information, etc., and incremental power analysis is performed based on each power resource information and power generation plan to determine the additional power corresponding to each power resource, wherein the additional power represents the additional power that can be supplied by increasing the work of the power resource on the basis of the original power generation plan. The specific implementation method of incremental power analysis is no longer limited in the embodiments of the present application. In one achievable method, the theoretical power generation capacity is calculated based on the installed capacity in the power resource information to determine the theoretical power generation capacity; the equipment health is estimated based on the equipment status information in the power resource information to determine the equipment health coefficient, and the meteorological data corresponding to the emergency dispatch period is obtained, and the environmental impact is estimated based on the meteorological data to determine the environmental impact coefficient; the actual power generation capacity is calculated based on the theoretical power generation capacity, the equipment health coefficient and the environmental impact coefficient to determine the actual power generation capacity; the incremental power analysis is performed based on the actual power generation capacity and the power generation plan corresponding to each power resource to determine the additional power corresponding to each power resource.

[0037] Then, according to the order of the power resource scheduling sequence, the additional power corresponding to the power resource is selected one by one, and the additional power is combined with the original power generation plan to determine whether the power demand can be met. If it cannot meet the demand, the additional power corresponding to the next power resource is selected until the power supply capacity can meet the power demand. The power resource selected from the power resource scheduling sequence is recorded as the target power resource, and the power generation plan of the target power resource is adjusted so that the target power resource can supply more additional power on the original power generation plan, that is, the target power resource that needs power supply adjustment and the corresponding adjusted power generation plan are recorded in the emergency scheduling information.

[0038] It can be seen that in the embodiment of the present application, in the power system of the distribution network, there are different types of power generation resources, and different power generation resources have different power generation characteristics and cost-effectiveness. Based on the scheduling constraints, each power resource is prioritized and the power resource scheduling sequence is determined, so that the power can select appropriate power generation resources during the scheduling process and optimize the configuration of power resources. Then, the power resource information corresponding to each power resource in the distribution network is obtained, and the incremental power analysis is performed based on each power resource information and the power generation plan to determine the additional power corresponding to each power resource. Furthermore, based on the power resource scheduling sequence and the additional power corresponding to each power resource, the optimized scheduling analysis is performed to determine the emergency scheduling information.

[0039] Furthermore, in order to avoid failures or accidents in actual operation and improve the safety of emergency dispatch of the power grid, in the embodiment of the present application, after the emergency dispatch information is determined, the optimization dispatch analysis is performed based on the power resource dispatch sequence and the maximum additional power corresponding to each power resource, and the following is also included: Acquire multi-dimensional data corresponding to the distribution network, build a model based on the multi-dimensional data, and obtain a virtual model of the distribution network, wherein the multi-dimensional data includes: grid structure data, load distribution data, and power generation resource data; Obtain meteorological data corresponding to the emergency dispatch period, perform simulation tests based on load forecast information, meteorological data, emergency dispatch information and distribution network virtual model, and obtain simulation test results; When the simulation test result is passed, the emergency dispatch information is sent to the target power resource; when the simulation test result is failed, a dispatch information abnormality warning is generated to facilitate re-execution of the optimized dispatch analysis.

[0040] For the embodiment of the present application, the multi-dimensional data corresponding to the distribution network is obtained, and the multi-dimensional data includes but is not limited to: grid structure data, load distribution data, and power generation resource data, wherein the grid structure data is used to characterize the topological structure information of the distribution network, including the connection relationship and parameters of equipment such as substations, lines, switches, etc.; the load distribution data is used to record the load data of each node in the distribution network, that is, the historical load record; the power generation resource data is used to record the power generation capacity, power generation efficiency and other parameters of distributed power sources (for example, solar energy, wind energy, etc.). Then, the multi-dimensional data from different sources are standardized to ensure the comparability and compatibility between the data, and the data is converted into a format suitable for model construction, so as to facilitate the subsequent construction of the virtual model of the distribution network. Then, the model is constructed based on the multi-dimensional data to obtain a virtual model of the distribution network, which can accurately reflect the key information such as the structure, load distribution and power generation resources of the distribution network. For model construction, according to the characteristics and requirements of the distribution network, a suitable modeling method and tool are selected, that is, a modeling method based on a physical model or a modeling method based on data drive can be adopted. Model building features that have an important impact on model building, such as the shape of the load curve, the volatility of power generation resources, etc., are extracted, and the model is trained based on multi-dimensional data and model building features to obtain the initial distribution network virtual model. Then, the initial distribution network virtual model is optimized, for example, by adjusting model parameters, using more advanced algorithms, etc., to improve the accuracy and generalization ability of the model, and the initial distribution network virtual model is verified using historical data, and the verified model is used as the distribution network virtual model. Constructing a distribution network virtual model through multi-dimensional data of the distribution network can more comprehensively reflect the actual operating status of the distribution network, which helps to quickly and accurately evaluate the response capability and stability of the distribution network during emergency dispatch periods.

[0041] Furthermore, through the meteorological data platform or API interface, the meteorological data corresponding to the emergency dispatch period is obtained according to the geographical location and time range, and the load forecast information, meteorological data, and emergency dispatch information are input into the distribution network virtual model for simulation testing, simulating the operation of the distribution network when the distribution network executes the emergency dispatch information under the conditions of the load forecast information and meteorological data. After the simulation test is completed, the execution effect of the emergency dispatch strategy is determined according to the simulation test parameters in the distribution network virtual model. If there is no power supply abnormality or local power outage, the simulation test result is determined to be passed; if there is a power supply abnormality or local power outage, the simulation test result is determined to be failed. When the simulation test result is passed, the emergency dispatch information is sent to the target power resource; when the simulation test result is failed, a dispatch information abnormality warning is generated, and the dispatch information abnormality warning is used to remind the dispatch management personnel to re-execute the optimization dispatch analysis. Combining meteorological data, load forecast information and emergency dispatch information, simulation testing can simulate the operation status of the distribution network under different emergency scenarios. The simulation test can discover potential dispatch problems in advance, thereby avoiding failures or accidents in actual operation, and improving the safety of power grid emergency dispatch.

[0042] It can be seen that in an embodiment of the present application, multi-dimensional data corresponding to the distribution network is obtained, and a model is constructed based on the multi-dimensional data to obtain a virtual model of the distribution network. Then, the meteorological data corresponding to the emergency dispatch period is obtained, and a simulation test is performed based on the load forecast information, meteorological data, emergency dispatch information and the distribution network virtual model to obtain a simulation test result. When the simulation test result is passed, the emergency dispatch information is sent to the target power resource; when the simulation test result is failed, an abnormal dispatch information warning is generated to facilitate re-execution of the optimized dispatch analysis. Combining meteorological data, load forecast information and emergency dispatch information, a simulation test is performed to simulate the operating status of the distribution network under different emergency scenarios. The simulation test can discover potential dispatch problems in advance, thereby avoiding failures or accidents in actual operation, and improving the safety of power grid emergency dispatch.

[0043] Furthermore, in order to ensure the stable operation of the power grid and the reliability of power supply, in the embodiment of the present application, incremental power analysis is performed based on each power resource information and power generation plan to determine the additional power corresponding to each power resource, including: Calculate theoretical power generation capacity based on installed capacity in power resource information to determine theoretical power generation capacity; Estimating equipment health based on equipment status information in power resource information, determining equipment health coefficient, obtaining meteorological data corresponding to the emergency dispatch period, estimating environmental impact based on meteorological data, and determining environmental impact coefficient; Calculate the actual power generation capacity based on the theoretical power generation capacity, equipment health factor and environmental impact factor to determine the actual power generation capacity; An incremental power analysis is performed based on the actual power generation capacity and power generation plan corresponding to each power resource to determine the additional power generated by each power resource.

[0044] For the embodiment of the present application, accurately evaluating the maximum power generation potential of each power resource under ideal conditions is helpful to provide a reliable theoretical basis for power generation planning and power dispatching. Therefore, the theoretical power generation capacity is calculated based on the installed capacity in the power resource information and the length of the emergency dispatch period to determine the theoretical power generation capacity, where the theoretical power generation capacity refers to the amount of electricity that the power resource can theoretically generate under ideal conditions in the future emergency dispatch period, and the installed capacity refers to the sum of the rated capacities of the engine groups in the power resource, which is the maximum active power that the engine group can output under standard operating conditions. For the theoretical power generation capacity calculation method, the theoretical power generation capacity = installed capacity * emergency dispatch period.

[0045] Then, the power resource information records the equipment status of the power equipment, including but not limited to: operating time, maintenance records, fault history, current operating status, etc., and obtains the pre-established equipment health assessment model, and uses the equipment health assessment model and equipment status information to quantitatively assess the overall health status of the equipment and determine the equipment health coefficient, where the equipment health coefficient is usually a value between 0 and 1, indicating the ratio of the health status of the equipment to a brand new device. The equipment health assessment model is built based on the technical parameters and performance indicators of the equipment, and the equipment health assessment model can comprehensively consider various status information of the power equipment.

[0046] At the same time, a pre-established environmental impact assessment model is obtained. The environmental impact assessment model is established based on the operating characteristics of power equipment and the impact mechanism of meteorological conditions, and can comprehensively consider the impact of meteorological factors on the operating efficiency, safety, stability and other aspects of power equipment. Therefore, the environmental impact assessment model and meteorological data are used to estimate the environmental impact and determine the environmental impact coefficient, which is a numerical value that quantifies the impact of the meteorological environment on the operation of power equipment. Furthermore, the actual power generation capacity is calculated based on the theoretical power generation capacity, equipment health coefficient and environmental impact coefficient to determine the actual power generation capacity, where the actual power generation capacity = theoretical power generation capacity * equipment health coefficient * environmental impact coefficient. Combining the theoretical power generation capacity, equipment health coefficient and environmental impact coefficient to calculate the actual power generation capacity can produce a more accurate and practical power generation capacity assessment result, which helps the power dispatching department to allocate power resources more reasonably and ensure the stable operation of the power grid and the reliability of power supply. Finally, an incremental power analysis is performed based on the actual power generation capacity and power generation plan corresponding to each power resource to determine the additional power corresponding to each power resource. The additional power represents the additional electric energy that can be supplied by increasing the work of the power resource on the basis of the original power generation plan, that is, the additional electric energy that can be supplied by the actual power generation capacity compared with the power generation plan.

[0047] It can be seen that in the embodiment of the present application, the theoretical power generation capacity is calculated based on the installed capacity in the power resource information, the theoretical power generation capacity is determined, and the maximum power generation potential of each power resource under ideal conditions is accurately evaluated, which helps to provide a reliable theoretical basis for power generation plan formulation and power dispatching. Then, the equipment health estimation is performed based on the equipment status information in the power resource information, the equipment health coefficient is determined, and the meteorological data corresponding to the emergency dispatch period is obtained, and the environmental impact estimation is performed based on the meteorological data to determine the environmental impact coefficient. Furthermore, the actual power generation capacity is calculated based on the theoretical power generation capacity, the equipment health coefficient and the environmental impact coefficient to determine the actual power generation capacity. Combining the theoretical power generation capacity, the equipment health coefficient and the environmental impact coefficient to calculate the actual power generation capacity can obtain a more accurate and practical power generation capacity evaluation result, which helps the power dispatching department to allocate power resources more reasonably and ensure the stable operation of the power grid and the reliability of power supply. Finally, the incremental power analysis is performed based on the actual power generation capacity and power generation plan corresponding to each power resource to determine the additional power corresponding to each power resource.

[0048] Furthermore, in order to improve the accuracy of load forecasting, in an embodiment of the present application, demand forecasting is performed based on historical demand data, real-time load data, and auxiliary forecasting data to determine load forecasting information, including: Integrate historical demand data, real-time load data and auxiliary forecast data to obtain target demand data; Extracting a first feature based on the target demand data to determine a linear feature and a seasonal feature, and forecasting demand based on the linear feature and the seasonal feature to determine first load forecast information; Extracting a second feature based on the target demand data to determine a nonlinear feature, and performing demand forecasting based on the nonlinear feature to determine second load forecasting information; A combined prediction is performed based on the first load prediction information and the second load prediction information to determine the load prediction information.

[0049] For the embodiments of the present application, in order to improve the accuracy of load forecasting, in the process of executing load forecasting, the linear characteristics, nonlinear characteristics and seasonal characteristics of the power demand data are comprehensively considered, and a method of combining predictions of multiple models is adopted to perform load forecasting, thereby providing the power system with accurate and reliable load forecasting information.

[0050] Specifically, data cleaning is performed based on historical demand data, real-time load data, and auxiliary forecast data. Data cleaning is used to check the integrity of the data, identify and correct outliers in the data, and convert the data into a consistent format and unit. Then, data fusion technology is used to integrate the historical demand data, real-time load data, and auxiliary forecast data after data cleaning, and merge them into a unified database to make the target demand data more complete, accurate, and reliable. Since electricity demand is often affected by seasonal factors, festive factors, etc., the electricity demand shows large fluctuations, and the target demand data usually includes data with linear characteristics and seasonal characteristics. Therefore, the first feature extraction is performed based on the target demand data to determine the linear characteristics and seasonal characteristics, wherein the linear characteristics refer to the characteristics that have a linear relationship with the electricity demand, and the seasonal characteristics refer to the characteristics related to the season in the target demand data. Furthermore, demand forecasting is performed based on the linear characteristics and seasonal characteristics to determine the first load forecasting information.

[0051] At the same time, there are many nonlinear relationships in actual electricity demand, such as the nonlinear correlation between economic activities and electricity demand. These nonlinear relationships cannot be accurately captured by simple linear models. Therefore, the second feature extraction is performed based on the target demand data to determine the nonlinear feature, and the demand forecast is performed based on the nonlinear feature to determine the second load forecast information. When performing demand forecasting for nonlinear features, a model suitable for nonlinear feature prediction can be selected, such as convolutional neural network, BP neural network, etc. Then, demand forecasting is performed based on nonlinear features to determine the second load forecast information. Finally, a combined forecast is performed based on the first load forecast information and the second load forecast information to determine the load forecast information. For the combined forecast, weighted average, Bayesian combination and other methods can be used to combine the two forecast results to obtain more accurate load forecast information.

[0052] It can be seen that in the embodiment of the present application, data integration is performed based on historical demand data, real-time load data and auxiliary forecast data to obtain target demand data. Then, a first feature extraction is performed based on the target demand data to determine linear features and seasonal features, and demand forecasting is performed based on the linear features and seasonal features to determine the first load forecasting information. Furthermore, a second feature extraction is performed based on the target demand data to determine nonlinear features, and demand forecasting is performed based on the nonlinear features to determine the second load forecasting information. Finally, a combined forecast is performed based on the first load forecasting information and the second load forecasting information to determine the load forecasting information. In order to improve the accuracy of load forecasting, in the process of executing load forecasting, the linear features, nonlinear features and seasonal features of the power demand data are comprehensively considered, and a method of combining multiple models for forecasting is used to perform load forecasting, thereby providing accurate and reliable load forecasting information for the power system.

[0053] Furthermore, in order to improve the operating efficiency of the entire power system and timely discover the imbalance between supply and demand in the power system, in an embodiment of the present application, supply and demand analysis is performed based on each power generation plan and load forecast information to determine the supply and demand analysis results, including: Perform power supply calculation based on each power generation plan to determine power supply information; Based on the supply and demand analysis of the power supply information and the load forecast information, the supply and demand analysis results are determined, wherein the supply and demand analysis results include: oversupply, shortage of supply and supply and demand balance.

[0054] For the embodiments of the present application, through supply and demand analysis, the supply and demand imbalance in the power system can be discovered in a timely manner, and based on the supply and demand analysis results, it helps to more reasonably allocate and dispatch electric energy, avoid waste and shortage of electric power resources, and improve the operating efficiency of the entire power system.

[0055] Specifically, the power generation plan includes the expected power generation of power resources in each time period (for example, hour, day, week, month), and the expected power generation corresponding to each power resource is recorded and summarized to obtain the total power supply information of the distribution network. Then, preprocessing is performed based on the power supply information and load forecast information to ensure that the two maintain consistency in time scale and data format, and the power supply diagram and power consumption diagram corresponding to the power supply information and load forecast information are drawn, wherein the horizontal axis of the power supply diagram is time and the vertical axis is power supply; the horizontal axis of the power consumption diagram is time and the vertical axis is power consumption. Further, the first area corresponding to the supply and demand analysis period is calculated in the power supply diagram, and the second area corresponding to the supply and demand analysis period is calculated in the power consumption diagram, wherein the two end points of the supply and demand analysis period are selected on the horizontal axis, and two straight lines are drawn perpendicularly to the horizontal axis through the two end points, intersecting with the power supply curve above, and the area enclosed by the two straight lines, the power supply curve, and the horizontal axis is calculated, which is recorded as the first area; the calculation method of the second area is similar to that of the first area, which will not be repeated here. Then, supply and demand analysis is performed based on the first area and the second area to determine the supply and demand analysis result, that is, the electronic device pre-stores the corresponding relationship between the first area, the second area and the supply and demand analysis result. That is, when the first area is larger than the second area, and the difference between the two is larger than the power supply surplus threshold, the supply and demand analysis result is determined to be supply exceeding demand; when the first area is smaller than the second area, and the difference between the two is larger than the power supply shortage threshold, the supply and demand analysis result is determined to be supply insufficient; otherwise, the supply and demand analysis result is determined to be supply and demand balance.

[0056] It can be seen that in the embodiment of the present application, the power supply calculation is performed based on each power generation plan to determine the power supply information, and then the supply and demand analysis is performed based on the power supply information and the load forecast information to determine the supply and demand analysis results, wherein the supply and demand analysis results include: oversupply, undersupply and supply and demand balance. Through supply and demand analysis, the supply and demand imbalance in the power system can be discovered in a timely manner, and based on the supply and demand analysis results, it is helpful to more reasonably allocate and dispatch electric energy, avoid waste and shortage of electric resources, and improve the operating efficiency of the entire power system.
