BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the multi-regional electricity consumption coupling prediction method of the present invention. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1, Figure 1The invention provides a method for predicting coupled power consumption in multiple regions, comprising the following steps: S1, collecting power consumption coupling data of the area to be tested, wherein the power consumption coupling data includes power transmission data, grid stability, historical power demand data and load fluctuation status data.

[0018] In this real-time example, the power consumption coupling data includes power transmission impact data, grid stability, historical power demand data and load fluctuation status data, specifically: Power transmission influencing data, the power transmission influencing data including transmission distance, load demand, resistance loss and resistivity, and constructing a power transmission influencing model based on the power transmission influencing data based on a machine learning algorithm to obtain the optimal power transmission efficiency, specifically: The specific steps for obtaining the power transmission efficiency are as follows: Obtain the location information between the areas to be tested, and use the Haversine formula to calculate the length of the power transmission line between the two areas; Obtain historical load data in the area to be tested, and remove missing values ​​and outliers in the collected historical load data through interpolation and interquartile range methods, retain normal data, and use the cleaned load data to calculate the average load in each time period; Acquiring performance parameters of cables for power transmission between the test areas, wherein the cable performance parameters include resistivity, cross-sectional area, and rated voltage; The resistance loss is calculated based on a preset resistance loss formula according to the load demand, the length of the power transmission line, the resistivity, the cross-sectional area and the rated voltage to obtain the resistance loss; The optimal power transmission efficiency between the areas to be tested is obtained by calculating based on a preset power transmission efficiency formula according to the resistance loss and load demand.

[0019] The specific calculation formula of the power transmission efficiency is as follows:

[0020] The specific calculation formula of the resistance loss is as follows:

[0021] In the formula, is the power transmission efficiency, is the load demand, Represents resistance loss, which is the energy loss caused by current passing through resistance. Indicates the voltage at which power is transmitted. represents the resistivity of the material, represents the cross-sectional area of ​​the transmission cable, Represents the length of the power transmission line between two areas.

[0022] Further, the advantages of considering resistance loss from the perspective of load demand, power transmission line length, resistivity, cross-sectional area and rated voltage are analyzed: Resistive loss plays a vital role in the power system, which directly affects the transmission efficiency and cost of electric energy. First, the increase in load demand will lead to an increase in current. According to Ohm's law, the resistance loss is proportional to the square of the current. Therefore, understanding the load demand helps to optimize the design of the power transmission system, select the appropriate voltage level and conductor size, effectively reduce resistance loss, and improve transmission efficiency.

[0023] Secondly, the length and resistivity of the power transmission line are important factors affecting resistance loss. As the line length increases, the resistance loss also increases. In long-distance transmission, the use of high-voltage transmission can effectively reduce the current, thereby reducing resistance loss. By selecting low-resistivity conductor materials, the transmission efficiency can be further improved and energy loss can be reduced.

[0024] Finally, there is a significant relationship between the cross-sectional area of ​​the wire and the resistance loss. Increasing the cross-sectional area of ​​the wire effectively reduces the resistance and thus reduces the loss. However, this will also increase the material cost, so a balance needs to be struck between cost and efficiency in the design. By comprehensively optimizing these factors, the overall performance of the power system can be significantly improved, ensuring safe and efficient transmission of electrical energy.

[0025] Grid stability refers to the ability of the power system to maintain its normal operating state and restore to a balanced state when it is disturbed or fails. Stability is crucial to the safe, reliable and economical operation of the power system.

[0026] The specific steps for obtaining the grid stability are as follows: Acquire performance parameters of the generator in the area to be tested, wherein the performance parameters of the generator include mechanical power, rated power, rated speed, voltage and current of the generator; Collect the power system frequency of the area to be tested within a period of time, and smooth the acquired frequency data through time series analysis method to obtain the characteristic value of the frequency; The fundamental frequency of the system is obtained by calculation based on a preset system fundamental frequency formula according to the characteristic value of the frequency; Collect the voltage and current signals in the power system in the area to be tested, process the signals through Fourier transform, extract the frequency domain information, and obtain the phase angle between the voltage and current; The electrical power is obtained by calculating the voltage and the current based on a phase angle between the voltage and the current and the voltage and the current based on a preset electrical power formula; The generator-related constants are obtained by the moment of inertia test method; The moment of inertia is calculated based on a preset moment of inertia formula according to the constants, rated power and rated speed related to the generator; The grid stability is obtained by calculating based on the rotational inertia, the fundamental frequency of the system, the electrical power and the mechanical power based on a preset grid stability model.

[0027] The specific calculation formula for the grid stability is as follows:

[0028] The specific calculation formula of the fundamental frequency of the system is as follows:

[0029] The specific calculation formula of the electrical power is as follows:

[0032] It should be noted that in the power system, the standard frequency of the system is in the range of 50Hz~60Hz. The higher the stability coefficient of the power grid, the higher the stability of the power grid and the efficiency of energy dispatch, the higher the coupling of power consumption between regions, and the smaller the safety risks; when the stability coefficient of the power grid is lower than the preset value, the efficiency of energy dispatch is lower, and the coupling of power consumption between regions is lower, indicating that the power grid system in the area has a fault and requires manual maintenance from the outside.

[0035] The specific calculation formula of the power demand data is as follows:

[0036] In the formula, is the power demand, is the voltage, represents the instantaneous voltage at time t, is the current, represents the instantaneous current at time t, is the length of the test period, is the load factor.

[0037] It should be noted that the load factor is the ratio of the actual load to the maximum load. The normal value is between 0.5 and 0.9. The power demand is directly proportional to the load factor. The power demand increases with the increase of the load factor.

[0038] Load fluctuation state, load fluctuation refers to the degree of change of power load within a certain period of time. It is an important indicator used to describe the degree and nature of load changes in the power system. It reflects the fluctuation of power load within a certain period of time. The greater the volatility, the more drastic the change of power load, and the greater the pressure faced by the power system in meeting load demand.

[0039] The specific steps for obtaining the load fluctuation state are as follows: Obtain the grid load data of the area to be tested within a period of time, process the grid load data, remove abnormal data, and ensure the reliability and accuracy of the data; According to the power grid load data, an average value of the power grid load is calculated, and a total amount of observed power grid load data is recorded; The load fluctuation state is obtained according to the total number of the observed data, the grid load and the average value of the grid load and based on a preset load fluctuation state formula.

[0042] S2, through the RegARIMA model and NeuralProphet model, the historical power demand data and historical load fluctuation status data are predicted and analyzed to obtain the power demand data and load fluctuation status of the tested area in the future.

[0043] In this embodiment, the historical power demand data and the historical load fluctuation state data are predicted and analyzed by the RegARIMA model and the NeuralProphet model to obtain the power demand data and the load fluctuation state of the tested area in the future period of time, specifically: The specific calculation formula of the RegARIMA model is as follows:

[0044] The specific calculation formula of the trend function is as follows:

[0045] The specific calculation formula of the periodic change is as follows:

[0046] The specific calculation formula for the holiday item is as follows:

It is used to reflect abnormal changes not reflected in the model, that is, the error term. is the carrying capacity, is the growth rate, is the offset parameter, is the regression parameter, is with The regression variables observed in the same period, is the error time series.

[0049] S3, constructing a power consumption coupling model based on a machine learning algorithm according to the power demand, power transmission efficiency and load fluctuation status data.

[0050] In this embodiment, the power consumption coupling model is constructed based on the machine learning algorithm according to the power demand, power transmission efficiency and load fluctuation state data, specifically: The specific calculation formula of the power consumption coupling model is as follows:

[0051] In the formula, It is the coupling of power consumption. represents the grid stability in the region, represents the electricity demand data of the region, represents the load fluctuation state of the th area, and i represents the number of areas.

[0052] It should be noted that the value of power consumption coupling is between [0,1]. The higher the value of power consumption coupling, the faster the dynamic response of the system, and other power generation equipment will be adjusted quickly to maintain stability. If the coupling value is lower, the dynamic response of the system will become slower, resulting in instability caused by load fluctuations, and then causing abnormal changes in voltage and frequency.

[0053] S4, according to the power consumption coupling model, the predicted power demand, power transmission efficiency and load fluctuation state data are input for calculation to obtain the power consumption coupling coefficient between the areas to be measured.

[0054] In this embodiment, according to the power consumption coupling model, the predicted power demand, power transmission efficiency and load fluctuation state data are input for calculation to obtain the power consumption coupling coefficient between the areas to be measured, which is specifically: Obtain the power demand data and load status data of the area to be tested, and use the RegARIMA model and NeuralProphet model to predict and analyze the historical power demand data and historical load fluctuation status data to obtain the power demand data and load status data for a period of time in the future; Inputting the power demand data and load status data in the future period into the power consumption coupling model to achieve the prediction of the coupling of power consumption in the future period; If the value of the power consumption coupling is lower than the preset value, it is necessary to adjust the values ​​of other parameters in the power consumption coupling model; When the parameter value is adjusted to the optimal state, and the power consumption coupling value is still lower than the preset value, the system will issue an alarm to remind managers whether to interrupt energy scheduling to other areas or increase energy scheduling to other areas, thereby increasing the power consumption coupling value to improve the system's emergency response capabilities and reduce the risk of power outages.
