[0078] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.
[0079] Figure 1 A flowchart of a remote power supply monitoring method for shelter equipment based on the Internet of Things is provided for an embodiment of the present application, such as Figure 1 As shown, the method includes:
[0080] 101. Monitor each electrical device in real time and send the monitoring data to the cloud server to obtain real-time monitoring data;
[0081] Real-time monitoring refers to the continuous data collection of power usage of electrical equipment through sensors, smart meters and other equipment. These data include but are not limited to current, voltage, power, energy consumption and other information. The collected data is sent to the cloud server through network transmission technology (such as 4G / 5G, Wi-Fi, etc.) to form real-time monitoring data.
[0082] In the embodiment of the present application, monitoring devices are installed on each power-consuming device, which collect power consumption data of the device regularly or continuously and upload the data to a cloud server via the network. The cloud server receives and stores the data to form a real-time updated database, which provides a basis for subsequent analysis.
[0083] Assume that there is a smart factory with a variety of electrical equipment, including motors on the production line, lighting systems, air conditioning systems, etc. In order to achieve real-time monitoring and optimal management of these devices, a monitoring system based on the Internet of Things (IoT) is deployed.
[0084] First, install and configure the equipment: install smart meters and sensors on each key power-consuming device. For example, install current sensors and voltage sensors on motors, and energy consumption monitors on lighting systems. Ensure that each sensor is connected to the factory's internal network via wired or wireless means (such as Wi-Fi, 4G / 5G). For wireless connections, ensure network coverage and stability.
[0085] Secondly, perform data collection: set the frequency of data collection, such as collecting current, voltage, power and other data once every minute. According to actual needs, the collection frequency can be adjusted to balance data accuracy and network load. Define a unified data format for subsequent processing and analysis. For example, the data format can be defined as structured data containing fields such as device ID, timestamp, current, voltage, power, etc.
[0086] Further, data transmission is performed: the data collected by the sensor is transmitted to the local gateway of the factory through the internal network. The local gateway is responsible for preliminary data processing and packaging. The local gateway securely transmits the packaged data to the cloud server via the Internet. The HTTPS protocol can be used to ensure the security of data transmission.
[0087] Furthermore, cloud data storage and processing are performed: the cloud server receives and stores data from various sensors. The data is stored in a database, which can be a relational database or a NoSQL database. The cloud server pre-processes the data, including data cleaning (removing outliers and missing values), data conversion (unit conversion, timestamp synchronization, etc.) and data aggregation (aggregating data by time interval).
[0088] Finally, real-time monitoring and alarm: The cloud platform provides a real-time monitoring interface to display the current status and historical data of each power-consuming device. Managers can access this information through the web interface or mobile application. Set threshold alarms. When the power consumption of a device exceeds the preset threshold, the system automatically sends an alarm notification to relevant personnel, such as through SMS, email, or APP push.
[0089] Here is a specific example:
[0090] Sensor data collection:
[0091] Motor A: Current = 10A, Voltage = 220V, Power = 2.2kW, Timestamp = 2024-11-26 23:05:00 Lighting System B: Energy consumption = 500Wh, Timestamp = 2024-11-26 23:05:00
[0092] Data upload:
[0093] The sensor data is transmitted to the local gateway via Wi-Fi. The local gateway packages the data into a structured data format and transmits it securely to the cloud server via the HTTPS protocol.
[0094] Cloud data processing:
[0095] After receiving the data, the cloud server cleans and preprocesses the data and then stores it in the database.
[0096] Data cleaning example: If the current value of a data point is detected to be abnormally high (e.g., outside the normal range), it is marked as an outlier and removed.
[0097] Data conversion example: Convert timestamps to UTC time to ensure that the time base of all data is consistent.
[0098] Data aggregation example: Summarize the average power and total energy consumption of each device on an hourly basis.
[0099] Real-time monitoring and alarm:
[0100] The real-time current, voltage and power graphs of motor A are displayed via the web interface.
[0101] If the power of motor A exceeds 2.5kW, the system automatically sends an alarm notification to the maintenance personnel.
[0102] Through the above embodiments, real-time monitoring of various power-consuming equipment is achieved, and the monitoring data is safely and efficiently transmitted to the cloud server, providing a solid foundation for subsequent power demand forecasting and optimized scheduling.
[0103] 102. Based on the real-time monitoring data, use the support vector machine model to predict the future trend of electricity demand changes, conduct a multi-dimensional comprehensive analysis based on seasonal factors and historical electricity consumption patterns, and generate an accurate electricity demand forecast report;
[0104] Support vector machine (SVM) is a supervised learning method used for classification and regression analysis. In this step, the SVM model is used to predict the future trend of electricity demand. Seasonal factors refer to the electricity consumption patterns in different seasons, and historical electricity consumption patterns refer to electricity consumption data over a period of time in the past. Multi-dimensional comprehensive analysis refers to comprehensive analysis combining multiple factors (such as time, weather, holidays, etc.) to improve the accuracy of the forecast.
[0105] In the embodiment of the present application, first, real-time monitoring data is obtained from the cloud server and combined with historical electricity consumption data. Then, the SVM model is used to train the data and improve the prediction accuracy by optimizing the model parameters. The model will take into account seasonal factors, historical electricity consumption patterns, and other external factors (such as weather, social activities, etc.), and finally generate an accurate electricity demand forecast report.
[0106] Optionally, in step 102, based on the real-time monitoring data, a support vector machine model is used to predict the future trend of electricity demand changes, and a multi-dimensional comprehensive analysis is performed based on seasonal factors and historical electricity consumption patterns to generate an accurate electricity demand forecast report, including:
[0107] Perform real-time monitoring on each power-consuming device, and send the monitoring data to a cloud server to obtain the real-time monitoring data; utilize the real-time monitoring data, in combination with historical power consumption data, pre-process the data based on seasonal factors and historical power consumption patterns, and obtain the pre-processed data; train a support vector machine model based on the pre-processed data, and improve the prediction accuracy by optimizing model parameters; use the trained model to predict future trends in power demand changes to obtain power demand prediction values; based on the power demand prediction values, conduct a comprehensive analysis in combination with seasonal factors, historical power consumption patterns, and external influencing factors to generate an accurate power demand prediction report.
[0108] The method includes training the support vector machine model based on the preprocessed data, improving the prediction accuracy by optimizing the model parameters, and using the trained model to predict the future trend of power demand changes to obtain a power demand prediction value, including:
[0109] The preprocessed data is used as the input of the support vector machine model to perform model training to obtain a preliminarily trained support vector machine model; based on the preliminarily trained support vector machine model, the model parameters are optimized using a cross-validation method to improve the generalization ability and prediction accuracy of the model to obtain an optimized support vector machine model; the optimized support vector machine model is used in combination with the latest real-time monitoring data and the preprocessing process to predict the trend of electricity demand changes in a certain period of time in the future to obtain a preliminary electricity demand forecast value; based on the preliminary electricity demand forecast value, a comprehensive correction is performed in combination with seasonal factors, historical electricity consumption patterns and external influencing factors to generate a final electricity demand forecast report to obtain the electricity demand forecast value.
[0110] The method of using the real-time monitoring data, combining the historical electricity consumption data, and preprocessing the data based on seasonal factors and historical electricity consumption patterns to obtain the preprocessed data includes:
[0111] Using the real-time monitoring data from each power-consuming device and combining it with historical power consumption records, these data are collected and integrated to obtain a comprehensive database; based on the comprehensive database, the data therein is cleaned to remove abnormal values and missing values to obtain cleaned data; using the cleaned data, seasonal and periodic power consumption patterns are analyzed to identify the power consumption characteristics of different time periods and the power consumption patterns of different seasons to obtain power consumption pattern analysis results; based on the power consumption pattern analysis results, statistical methods and data mining techniques are used to deeply process the cleaned data, extract key features, and obtain feature extraction results; calculate the impact of external influencing factors on the power consumption pattern, quantify the external influencing factors and add them to the feature extraction results for further processing to improve the accuracy and reliability of the prediction model and obtain feature data after considering external factors; integrate the feature data after considering external factors to form preprocessed data.
[0112] In the embodiment of the present application, it is assumed that there is a smart industrial park with a variety of electrical equipment, including motors on production lines, lighting systems, air conditioning systems, etc. In order to achieve real-time monitoring and optimal management of these devices, a monitoring system based on the Internet of Things (IoT) is deployed, and a support vector machine (SVM) model is used to predict power demand.
[0113] First, install smart meters and sensors on each key power-consuming device to collect current, voltage, power and other data every minute, and send the data to the cloud server via Wi-Fi or 4G / 5G network. Obtain the power consumption records of the past year from the cloud server, including the power consumption of each device, timestamp and other information. Integrate the real-time monitoring data and historical power consumption data into a comprehensive database to form a data set containing timestamps, device identification, power consumption and other information.
[0114] Secondly, remove outliers and missing values. For example, if the current value of a data point is abnormally high (for example, exceeding the normal range), mark it as an outlier and remove it. At the same time, fill in missing values, which can be filled using interpolation or the previous valid value. Analyze the electricity consumption characteristics of different time periods (such as weekdays, weekends, and holidays), as well as the electricity consumption patterns of different seasons (spring, summer, autumn, and winter). For example, the electricity consumption of air conditioning systems is usually higher in summer.
[0115] Furthermore, statistical methods and data mining techniques, such as cluster analysis and association rule analysis, are used to deeply process the cleaned data and extract key features. For example, the daily average power consumption and peak power consumption of each device are calculated. External influencing factors, such as weather conditions (temperature, humidity), social activities (holidays, large-scale events), etc., are considered, and these factors are quantified and added to the feature extraction results. For example, hot weather will lead to an increase in the power consumption of the air conditioning system.
[0116] Furthermore, the preprocessed data is used as the input of the support vector machine model for preliminary training to obtain a preliminarily trained support vector machine model. The model parameters are optimized using the cross-validation method to improve the generalization ability and prediction accuracy of the model. For example, K-fold cross-validation is used to select the best kernel function parameters and regularization parameters. The optimized support vector machine model is used in combination with the latest real-time monitoring data and preprocessing process to predict the trend of electricity demand changes in a certain period of time in the future and obtain a preliminary electricity demand forecast value.
[0117] Finally, based on the preliminary power demand forecast, a comprehensive correction is made in combination with seasonal factors, historical power consumption patterns, and external factors. For example, if the temperature is predicted to rise in the next week, the forecast value is adjusted to reflect the increase in power consumption of the air conditioning system. Based on the corrected forecast value, the final power demand forecast report is generated. The report includes information such as the total power consumption forecast for the next period of time, the power consumption forecast for each device, and the potential power supply and demand imbalance warning.
[0118] Here is a specific example:
[0119] Data collection and integration:
[0120] Motor A: Current = 10A, Voltage = 220V, Power = 2.2kW, Timestamp = 2024-11-26 23:05:00 Lighting System B: Energy consumption = 500Wh, Timestamp = 2024-11-26 23:05:00

[0135] The present application takes into account that in the power system, accurate prediction of future power demand is essential to ensure power supply and demand balance, optimize scheduling and resource management. By analyzing historical power consumption data, seasonal factors and external influencing factors, a mathematical model can be constructed to predict future power consumption and power demand. The two formulas E(t) and P(t) used in this embodiment are designed based on time series analysis, statistical feature extraction and seasonal power consumption pattern analysis.
[0136] Optionally, the cleaned data is used to analyze seasonal and periodic electricity consumption patterns, identify electricity consumption characteristics in different time periods and electricity consumption patterns in different seasons, and obtain electricity consumption pattern analysis results, including:

[0143] After calculating P(t), a detailed power consumption pattern analysis report is generated through verification and calibration, visualization, and sensitivity analysis, providing a scientific basis for the management and dispatch of the power system.
[0144] The purpose of this formula is to comprehensively consider multiple factors such as periodicity, seasonality, and external influences in formulas E(t) and P(t) to improve the accuracy of the prediction; use nonlinear functions (such as sinusoidal functions, logarithmic functions, Gaussian functions, etc.) to capture the complex changes in power consumption patterns and improve the fitting ability of the model; obtain model parameters by fitting historical data so that the model can adapt to different power consumption patterns and environmental conditions.

These parameters are also obtained by fitting historical data;F(t): A function affected by external factors, such as weather temperature, social activities, etc. The specific form of F(t) can be determined by relevant data analysis.
[0162] Assume data:
[0163] Historical electricity usage data: electricity usage per hour over the past year.
[0164] Economical electricity consumption pattern S(t): higher electricity consumption in summer and lower electricity consumption in winter.
[0165] External influencing factors F(t): weather temperature T weather .
[0166] Parameter settings:
[0167] E(t) parameters: α=1.5; β=0.8; γ=0.3; δ=0.2; ∈=50; T=24 hours; D=7 days; φ=0.5; ψ=0.3; t0=14 hours; σ=2; : η=1.2; ζ=0.1; θ=0.5; κ=0.3; ρ=0.2; ν=10; Y=365 days; Q=90 days; ε=0.4; λ=0.2; μ=100kW; F(t)=0.1×T weather
[0168] Calculation process:
[0169] Calculate E(t):
[0170] A specific time point t = 14 hours (2 pm) was selected.
[0171] Assume S(t) = 1.2 (electricity consumption is higher in summer).
[0172] Assume T weather =30 degrees (hot weather).
[0173] E(14)=1.5·sin(1.17+0.5)+0.8·sin(1.26+0.3)+0.3·log(2.2)+0.2
[0174] exp(0)+50
[0175] E(14)≈52.7347kW
[0176] Calculate P(t)
[0177] Use E(14)≈52.7347kW.
[0178] Assume F(14)=0.1×30=3.
[0179]
[0180] Conclusion Explanation:
[0181] E(14)≈52.7347kW: At 2 p.m., the predicted power consumption is about 52.7347 kW. This reflects the power consumption characteristics during this time period, including daily cycles, weekly cycles, seasonal factors, and peak power consumption at specific time points.
[0182] P(14)≈10.8924kW: At 2pm, the predicted power demand is about 10.8924kW. This reflects the changing trend of future power demand, combining the influence of power consumption, annual periodicity, quarterly periodicity and external factors (such as hot weather).
[0183] Assume that at 2 pm on a certain day, the calculated power consumption E(14)≈52.7347 kW and the power demand P(14)≈10.8924 kW.
[0184] Electricity consumption E(14)≈52.7347kW:
[0185] Assuming that the normal power consumption range is between 40KW and 60KW, since 40kW<52.7347kW<60kW, the power consumption is within the normal range and no special response measures are required.
[0186] Power demand P(14)≈10.8924kW:
[0187] Assuming that the normal range of power demand is between 5KW and 15KW, since 5kW<10.8924kW<15kW, the power demand is also within the normal range and no special response measures are required.
[0188] Through the above calculations, we get the specific power consumption and power demand forecast values. These results can be used to generate detailed power consumption pattern analysis reports, providing a scientific basis for the management and dispatch of power systems. For example, we can adjust the output power of the generator set in advance according to the forecast results, optimize the working schedule of the power equipment, and ensure the balance of power supply and demand.
[0189] 103. Based on the power demand forecast report, when an imbalance between power supply and demand is predicted, an optimization scheduling strategy based on a particle swarm optimization algorithm is initiated to dynamically adjust the output power of the generator set or the working schedule of the power-consuming equipment, and a fault tree analysis technique is used to evaluate potential risk points, generate an emergency response plan and optimize the scheduling results;
[0190] Particle swarm optimization (PSO) algorithm is a heuristic optimization algorithm used to solve complex optimization problems. In this step, the PSO algorithm is used to dynamically adjust the output power of the generator set or the working schedule of the power-consuming equipment to balance the supply and demand of electricity. Fault tree analysis (FTA) is a system safety analysis method used to identify and evaluate potential risk points. Emergency response plans are response measures formulated for possible emergencies.
[0191] In the embodiment of the present application, according to the power demand forecast report, if it is found that there is an imbalance in power supply and demand in a certain period of time in the future, the optimization scheduling strategy based on the PSO algorithm is started. This strategy ensures the effective use of power resources by dynamically adjusting the output power of the generator set or the working schedule of the power-consuming equipment. At the same time, the FTA technology is used to conduct a risk assessment on the preliminary optimization scheduling plan, identify potential risk points, and generate corresponding emergency response plans. Finally, the optimization scheduling strategy and the emergency response plan are combined to generate the optimization scheduling result.
[0192] Optionally, in step 103, based on the power demand forecast report, when an imbalance in power supply and demand is predicted, an optimization scheduling strategy based on a particle swarm optimization algorithm is initiated to dynamically adjust the output power of the generator set or the working schedule of the power-consuming equipment, and a fault tree analysis technique is used to evaluate potential risk points, generate an emergency response plan and an optimization scheduling result, including:
[0193] Using the power demand forecast report, the future power supply and demand balance is evaluated and processed, and when a power supply and demand imbalance is predicted, a power supply and demand imbalance warning signal is generated;
[0194] Based on the power supply and demand imbalance warning signal, an optimization scheduling strategy based on a particle swarm optimization algorithm is initiated to dynamically adjust the output power of the generator set or the working schedule of the power-consuming equipment to obtain a preliminary optimization scheduling plan;
[0195] Using fault tree analysis technology, risk assessment is performed on the preliminary optimization scheduling plan to generate a risk assessment report;
[0196] Based on the risk assessment report, conduct an in-depth analysis of various potential risk points and the chain reactions they may cause, and obtain an emergency response plan;
[0197] Combined with the preliminary optimization scheduling plan and the emergency response plan, the management and scheduling of power resources are comprehensively processed to generate an optimization scheduling result.
[0198] Optionally, the use of fault tree analysis technology to perform risk assessment processing on the preliminary optimization scheduling plan to generate a risk assessment report includes:
[0199] Using fault tree analysis technology, systematically analyze the key links and potential risk points in the preliminary optimization scheduling plan, identify various factors that may cause power system failures, and obtain a list of risk factors;
[0200] Based on the risk factor list, a fault tree model is constructed to clarify the logical relationship between various risk factors and their influence on the overall system stability, and a fault tree structure diagram is obtained;
[0201] Using the fault tree structure diagram, qualitative and quantitative risk assessment is performed to calculate the probability of occurrence of each risk event and the severity of its consequences, thereby obtaining risk assessment data;
[0202] Based on the risk assessment data, analyze the impact of different risk events on the balance of power supply and demand, evaluate the risks that may arise during the implementation of the optimized scheduling plan, and obtain risk assessment conclusions;
[0203] Based on the risk assessment conclusions, risk prevention and control recommendations are put forward and a risk assessment report is formed.
[0204] Suppose there is a smart grid system that manages the power supply and demand of a city. Through real-time monitoring and historical data analysis, the system generates a power demand forecast report for the next week. According to the forecast report, it is found that there will be an imbalance in power supply and demand on a certain day. In order to deal with this situation, the system starts an optimization scheduling strategy based on the particle swarm optimization algorithm (PSO), and uses the fault tree analysis technology (FTA) to evaluate potential risk points, generate emergency response plans and optimize scheduling results.
[0205] First, based on the generated power demand forecast report, the future power supply and demand balance is evaluated. When the power supply and demand imbalance is predicted for a certain day, a power supply and demand imbalance warning signal is generated. For example, the forecast shows that on November 30, 2024, power demand will exceed supply capacity by 5%.
[0206] Secondly, based on the early warning signal of imbalance between power supply and demand, the optimization scheduling strategy based on the particle swarm optimization algorithm (PSO) is started. The output power of the generator set and the working schedule of the power equipment are dynamically adjusted to balance the power supply and demand. For example, the output power of generator set A is increased, and the production schedule of factory B is adjusted to operate during the off-peak period. A preliminary optimization scheduling plan is obtained, including the output power adjustment plan of each generator set and the working schedule adjustment plan of each power equipment.
[0207] Furthermore, the fault tree analysis technology is used to systematically analyze the key links and potential risk points in the preliminary optimization scheduling plan to identify various factors that may cause power system failures. For example, the overload of generator set A, the production line failure of factory B, etc. Based on the risk factor list, a fault tree model is constructed to clarify the logical relationship between each risk factor and its impact on the overall system stability. For example, the overload of generator set A may cause power outages, thereby affecting the stability of the entire power grid. Using the fault tree structure diagram, qualitative and quantitative risk assessments are performed to calculate the probability of each risk event and the severity of its consequences. For example, the probability of overload of generator set A is 1%, and the severity of the consequences is high. Based on the risk assessment data, the impact of different risk events on the balance of power supply and demand is analyzed, and the risks that may arise during the implementation of the optimization scheduling plan are evaluated. For example, the overload of generator set A may cause power outages, affecting 50% of users. Combined with the risk assessment data, risk prevention and control suggestions are put forward to form a risk assessment report. For example, it is recommended to add a standby generator set and formulate an emergency plan to deal with the overload of generator set A.
[0208] Finally, based on the risk assessment report, we deeply analyze various potential risk points and the chain reactions they may cause, and formulate emergency response plans. For example, if generator set A fails, we immediately start the backup generator set C and notify the maintenance team to repair it. Combined with the preliminary optimization scheduling plan and the emergency response plan, we conduct a comprehensive process on the management and scheduling of power resources to generate the final optimization scheduling results. For example, the final optimization scheduling plan includes the output power adjustment plan of generator set A, the production schedule adjustment plan of factory B, and the specific measures of the emergency response plan.
[0209] Here is a specific example:
[0210] Assessment of electricity supply and demand balance:

[0215] Preliminary optimization scheduling plan: the output power of generator set A is adjusted to 110%, and the production schedule of factory B is adjusted to 1:00 to 5:00 in the morning.
[0216] Risk Assessment Process:
[0217] List of risk factors: overload of generator set A, failure of production line of factory B.
[0218] Fault tree model: Overload of generator set A may cause power outage, affecting 50% of users; failure of the production line of factory B may cause production delays.
[0219] Qualitative and quantitative risk assessment: The probability of overloading of generator set A is 1%, and the severity of the consequences is high; the probability of production line failure in factory B is 2%, and the severity of the consequences is medium.
[0220] Risk assessment data: Overload of generator set A may cause power outage, affecting 50% of users; failure of the production line of factory B may cause production delays, affecting 10% of output.
[0221] Risk assessment conclusion: It is recommended to add backup generator sets and formulate emergency plans to deal with the overload of generator set A; it is recommended to strengthen the maintenance of the production line of factory B to reduce the occurrence rate of failures.
[0222] Emergency response plan and optimized dispatch results:
[0223] Emergency response plan: If generator set A fails, immediately start the backup generator set C and notify the maintenance team to carry out emergency repairs; if the production line B of the factory fails, immediately switch to the backup production line.
[0224] Comprehensive processing: The final optimized scheduling plan includes the output power adjustment plan of generator set A, the production schedule adjustment plan of factory B, and the specific measures of the emergency response plan.
[0225] Through the above embodiments, optimized scheduling and risk assessment based on power demand forecast reports are achieved, the stable operation of the power system is ensured, and a scientific basis and emergency measures are provided for dealing with potential risks.
[0226] The present application takes into account that in the power system, it is crucial to ensure the balance of power supply and demand. When an imbalance in power supply and demand is predicted at a certain point in the future, it is necessary to start an optimization scheduling strategy to adjust the output power of the generator set or the working schedule of the power-consuming equipment to achieve a balance between supply and demand. The two formulas G(t) and O(t) used in this embodiment are designed based on the particle swarm optimization algorithm (PSO) to calculate the gap between power supply and demand and generate the optimization scheduling target value.
[0227] Optionally, based on the power supply and demand imbalance warning signal, an optimization scheduling strategy based on a particle swarm optimization algorithm is started to dynamically adjust the output power of the generator set or the working schedule of the power-consuming equipment to obtain a preliminary optimization scheduling plan, including:
[0228] Before calculating the power supply and demand gap G(t) at time t, the power supply and demand model is constructed by analyzing and preprocessing the power demand forecast and historical operation data to prepare basic data for the calculation of G(t);
[0229]
[0230] Where G(t) is the gap between electricity supply and demand at time t, reflecting the degree of imbalance between electricity supply and demand; N is the number of generating units; M is the number of power-consuming devices; w i is the weight of the i-th generator set, reflecting its importance in the power system; P gen,i (t) is the current output power of the i-th generator set at time t; ΔP gen,i (t) is the power adjustment of the i-th generator set at time t; v j is the weight of the jth electrical equipment, reflecting its importance in the power system; P load,j (t) is the current power consumption of the jth electrical equipment at time t; ΔP load,j (t) is the power consumption adjustment of the jth electrical equipment at time t;
[0231] After calculating G(t), normalization is performed, the power adjustment ratio is calculated, and the particle swarm optimization algorithm is used to adjust power generation and power consumption, and finally the optimized scheduling target value O(t) is generated;
[0232]
[0233] Among them, O(t) is the optimized dispatch target value at time t, reflecting the effect of the optimized dispatch scheme; η, ζ, θ, k are model parameters, obtained by fitting historical data, and used to adjust the sensitivity and accuracy of the model; G(t) is the gap between power supply and demand at time t, reflecting the degree of imbalance between power supply and demand; N is the number of generators; M is the number of power-consuming equipment; Pgen,i (t) is the current output power of the i-th generator set at time t; ΔP gen,i (t) is the power adjustment of the i-th generator set at time t; P max,i is the maximum output power of the i-th generator set; P load,j (t) is the current power consumption of the jth electrical equipment at time t; ΔP load,j (t) is the power consumption adjustment of the jth electrical equipment at time t; P max,j is the maximum power consumption of the jth electrical equipment;
[0234] After calculating O(t), a detailed optimization scheduling plan is formed through the steps of verification and calibration, visualization, and sensitivity analysis to guide power system management and scheduling.
[0235] The purpose of this formula is that formulas G(t) and O(t) comprehensively consider the current status, weight and maximum capacity of generators and power-consuming equipment to improve the accuracy and practicality of optimized scheduling; use nonlinear functions (such as exponential functions) to capture the impact of the gap between electricity supply and demand on the optimization scheduling target and improve the fitting ability of the model; obtain model parameters by fitting historical data so that the model can adapt to different electricity supply and demand situations and environmental conditions.

This reflects the total generating capacity of the entire power system at time t.
[0240] This section calculates the weighted total power consumption of all power consumers at time t. The current power consumption of each power consumer is added to its power consumption adjustment, then multiplied by its weight, and finally the results of all power consumers are added together. This reflects the total power demand of the entire power system at time t.

[0244] η·exp(-ζ·G(t) 2 ) is designed to ensure that when the gap between electricity supply and demand is large, the optimal dispatch target value O(t) will be significantly reduced, thereby prompting the system to take more proactive measures to reduce the gap between supply and demand. This helps to improve the stability and reliability of the system.
[0245] This item is designed to ensure that the power utilization of the generator set is properly considered. Higher power utilization means that the generator set is closer to its maximum output capacity, which may lead to higher operating costs and maintenance requirements. By introducing this item, the optimized scheduling plan can avoid over-use of generator sets while ensuring the balance between supply and demand, thereby extending equipment life and reducing costs.

At 2 pm, the power supply and demand gap G(14)≈37.25kW exceeds the lower threshold but does not reach the upper threshold, indicating that there is a certain degree of imbalance in power supply and demand, and optimization scheduling measures need to be taken.

At 2 pm, the optimized dispatch target value O(14)≈2.44189 is between the upper and lower thresholds, indicating that the current optimized dispatch scheme works well, but further optimization is still needed to improve the overall efficiency of the power system.
[0267] Through the above calculations, the specific power supply and demand gap and the optimized dispatch target value are obtained. These results can be used to generate detailed optimized dispatch plans to guide the management and dispatch of power systems. For example, the output power of the generator set and the working schedule of the power equipment can be adjusted according to the optimized dispatch target value to ensure the balance of power supply and demand.
[0268] 104. Automatically manage the power resource shortage situation based on the optimization scheduling results, ensure the normal operation of high-priority equipment, and generate power management decision suggestions.
[0269] Automatic management refers to monitoring and dispatching power resources through an automated system to ensure the stable operation of the power system. High-priority equipment refers to equipment with important functions or critical tasks in the power system, and its power supply must be guaranteed first. Power management decision recommendations are made based on the results of optimized dispatching and are used to guide the management and dispatching of the power system.
[0270] In the embodiment of the present application, according to the optimization scheduling results, the system automatically manages the power resources and gives priority to the power supply of high-priority equipment. By real-time monitoring of the usage status of power resources, the power distribution is dynamically adjusted to prevent local shortages. At the same time, the system generates detailed power management decision suggestions, including the adjustment of the operating status of the generator set, the optimization of the use plan of the power equipment, etc., to provide a scientific basis for the managers of the power system and ensure the efficient and safe operation of the power system.
[0271] Optionally, the automatic management of power resource shortage based on the optimization scheduling result in step 104 to ensure normal operation of high-priority equipment and generate power management decision suggestions includes:
[0272] The optimization scheduling result is used to automatically adjust the distribution of power resources to obtain a power resource allocation plan; based on the power resource allocation plan, a power resource management mechanism is established to monitor the use status of power resources in real time, dynamically adjust power distribution, and obtain a power resource management mechanism; according to the power resource management mechanism, an emergency response level is set in the case of power resource shortage, and response measures of different levels are defined to obtain an emergency response level setting; in combination with the optimization scheduling result and the emergency response level setting, a comprehensive assessment is made on the operating status of the power system, and specific power management decision suggestions are put forward to obtain power management decision suggestions.
[0273] Assume that there is a smart grid system that manages the power supply and demand of a city. Through real-time monitoring, power demand forecasting and optimization scheduling strategy, the system has generated optimized scheduling results. In order to ensure the normal operation of high-priority equipment under the condition of tight power resources and generate power management decision recommendations, the system will perform the following steps.
[0274] First, according to the optimization scheduling results, the allocation of power resources is automatically adjusted. For example, the optimization scheduling results show that the output power of generator set A is increased to 110%, and the production schedule of factory B is adjusted to 1:00 a.m. to 5:00 a.m. Generate a power resource allocation plan, including the specific output power of each generator set, the working schedule of each power-consuming equipment, etc. For example, the output power of generator set A is 110%, and the production time of factory B is from 1:00 a.m. to 5:00 a.m., and the power supply priority of hospital C is the highest, and its power supply must be ensured.
[0275] Secondly, establish a power resource management mechanism to monitor the usage status of power resources in real time. For example, through smart meters and sensors, collect current, voltage, power and other data of each device once a minute and transmit them to the cloud server for analysis. According to the real-time monitoring data, dynamically adjust the power distribution. For example, if it is found that the power consumption in a certain area suddenly increases, the system will automatically adjust the power distribution in other areas to ensure overall balance.
[0276] Furthermore, according to the power resource management mechanism, the emergency response level in the case of power resource shortage is set. For example, three emergency response levels are defined:
[0277] Level 1 response: When the power gap is less than 5%, start the backup generator set and notify non-critical users to reduce power consumption.
[0278] Level 2 response: When the power gap is between 5% and 10%, start the backup generator set and limit the power consumption of some non-critical users.
[0279] Level 3 response: When the power gap exceeds 10%, start all backup generators and implement rotating power outages to ensure power supply to high-priority equipment (such as hospitals and traffic lights).
[0280] Finally, the operation status of the power system is comprehensively evaluated by combining the optimization dispatch results and the emergency response level setting. For example, the current power gap is 7%, which belongs to the second-level response level.
[0281] Decision-making suggestions: Propose specific power management decision suggestions. For example, start the backup generators B and C, limit the power consumption of factories D and E, and ensure the power supply of hospital C and traffic lights.
[0282] Here is a specific example:
[0283] Generator A outputs 110% power and factory B operates from 1am to 5am.
[0284] Power resource allocation plan: Generator set A outputs 110% power, factory B’s production time is from 1:00 to 5:00 in the morning, and hospital C has the highest power supply priority.
[0285] Establish a power resource management mechanism: Through smart meters and sensors, the current, voltage, power and other data of each device are collected every minute. According to the real-time monitoring data, the power distribution is adjusted dynamically. For example, if the power consumption in a certain area suddenly increases, the system automatically adjusts the power distribution in other areas.
[0286] Set emergency response levels: Define three emergency response levels, including starting backup generators, limiting electricity use by non-critical users, and other measures.
[0287] Comprehensive assessment and decision-making recommendations: The current power shortage is 7%, which is a secondary response level. Start backup generators B and C, limit the power consumption of factories D and E, and ensure the power supply of hospital C and traffic lights.
[0288] Through the above embodiments, automatic management of power resources based on optimized scheduling results is achieved, ensuring the normal operation of high-priority equipment under conditions of tight power resources, and generating specific power management decision recommendations, thereby improving the stability and reliability of the power system.
