Description

Technical Field

[0001] The present invention relates to the technical field of power consumption regulation, and in particular to an automatic power consumption regulation method based on power characteristics. Background Art

[0002] Currently, there are many large-scale activities in cities, such as concerts. The traditional power supply method mainly relies on the city power grid. However, due to the long distance between the concert venues, the city power grid often faces the problem of voltage instability caused by frequent voltage changes and high voltage during concerts. Therefore, more and more concerts will choose to use diesel generators or energy storage equipment to power the power supply to ensure voltage stability. However, the use of a single power supply method still has defects. Therefore, it is very necessary to study a concert power control method that uses a hybrid power supply of diesel generators or energy storage equipment.

[0003] Existing technologies include the invention patent application with publication number CN119029891A, which discloses a method for optimizing the operation of a multi-low-voltage flexible interconnected system for intelligent integrated circuits. The method includes: accurately controlling power transmission between control panels, optimizing resource allocation, and using a feedback mechanism to ensure that the system adjusts strategies based on real-time data, improving flexibility and adaptability, and significantly enhancing the intelligence and automation level of the power system. Another example of existing technologies is the invention patent application with publication number CN119378947A, which discloses a method for dynamic identification of power information based on deep learning. The method includes: effectively improving the identification speed of power status within a region, formulating a reasonable power transfer and allocation plan for the region, and ensuring the safe and efficient use of power within the region.

[0004] From the above scheme, it can be seen that the current automated power consumption control method lacks certain attention to the automated control of power supply methods between different performance time periods of a concert. Diesel generators are often unable to cope with scenarios that require frequent power conversion. However, diesel generators have the advantage of stable power supply. Although energy storage devices can respond quickly to power changes, they are often unstable at high power. During the performance period of a concert, there are often a large number of power supply environment changes such as lighting changes. If diesel generators are used for power generation at this time, power outages caused by excessive voltage load changes are likely to occur, thereby reducing the safety of the concert. If mobile energy storage devices are used for power supply at high power, problems such as flickering lights and abnormal changes in sound tones may occur due to heating of the mobile energy storage devices, thereby reducing the audience's experience of watching the concert. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic power consumption control method based on power characteristics, which solves the problems existing in the background technology.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides an automatic power consumption control method based on power characteristics, including: Step 1. Acquisition of concert power consumption information. Before the concert begins, the model, usage duration and initial estimated power usage value of each electrical equipment belonging to the concert at each monitoring time point in each performance time period are obtained.

[0007] Step 2. Analyze and control the power consumption of the concert. Calculate the estimated instantaneous power range at each monitoring time point during each performance period. Evaluate the power supply method for each performance period, and thus select the energy storage power supply performance period and diesel power generation performance period for the concert.

[0008] Step 3. Pre-processing of electricity consumption for the concert: analyzing the estimated number of mobile energy storage devices and the estimated number of diesel generators for the concert, sending them to the concert manager, and pre-charging the energy storage devices for the concert.

[0009] The beneficial effects of the present invention are as follows: (1) Step 1 of the present invention obtains the electricity consumption information of the concert, and facilitates subsequent analysis by obtaining data of the electrical equipment used in the concert.

[0010] (2) Step 2 of the present invention: Analyze and control the power consumption of the concert. The power consumption at each monitoring time point in each performance period of the concert is estimated, and prediction is made based on the estimated power change and power value. Thus, the power supply mode of the concert in each performance period is determined, and automatic power supply control is performed. A hybrid power supply mode is adopted to reduce the incidence of power outages caused by excessive voltage load changes, and reduce the incidence of problems such as light flickering and abnormal changes in sound tone caused by heating of mobile energy storage equipment, thereby ensuring the safety of the concert and the audience's experience.

[0011] (3) Step 3 of the present invention is to pre-process the electricity consumption for the concert. By analyzing the estimated number of mobile energy storage devices and the estimated number of diesel generators for the concert, the power supply equipment is prepared in advance, and the mobile energy storage devices are charged during a time period with lower electricity prices, thereby reducing the financial consumption of the concert.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Reference Figure 1 As shown, the present invention provides an automatic power consumption control method based on power characteristics, including: Step 1. Acquisition of concert power consumption information, before the concert begins, obtaining the model, usage time and initial estimated power usage value of each electrical equipment belonging to the concert at each monitoring time point in each performance time period.

[0016] In a specific embodiment, the method for obtaining the model, usage duration and initial estimated power usage value of each electrical equipment belonging to the concert at each monitoring time point in each performance time period is as follows: obtaining the model and usage duration of each electrical equipment belonging to the concert through the electrical equipment rental supplier, and obtaining the initial estimated power usage value of each electrical equipment belonging to the concert at each monitoring time point in each performance time period through the concert equipment usage schedule.

[0017] Step 1 of the present invention is to obtain the electricity consumption information of the concert, and to facilitate subsequent analysis by obtaining data of the electrical equipment of the concert.

[0018] Step 2. Analyze and control the power consumption of the concert. Calculate the estimated instantaneous power range at each monitoring time point during each performance period. Evaluate the power supply method for each performance period, and thus select the energy storage power supply performance period and diesel power generation performance period for the concert.

[0019] In a specific embodiment, the energy storage power supply performance time periods and diesel power generation performance time periods of the concert are screened by a specific screening method: if the power supply mode of the concert in a certain performance time period is mobile energy storage power supply, then the performance time period is marked as the energy storage power supply performance time period; otherwise, the performance time period is marked as the diesel power generation performance time period, thereby screening the energy storage power supply performance time periods and diesel power generation performance time periods of the concert.

[0020] In a specific embodiment of the present invention, the estimated instantaneous power interval of the concert at each monitoring time point in each performance period is calculated by analyzing the aging power fluctuation percentage of each electrical device belonging to the concert based on the model and usage time of each electrical device belonging to the concert. .

[0021] Based on the initial estimated power usage values of each electrical equipment in the concert at each monitoring time point during each performance period , where x represents the number of each electrical equipment, , y is a positive integer greater than 2, n represents the number of each performance time period, , m is a positive integer greater than 2, i represents the number of each monitoring time point, , j is a positive integer greater than 2.

[0022] Calculate the estimated instantaneous power range at each monitoring time point during each performance period of the concert .

[0023] In a specific embodiment of the present invention, the aging power fluctuation percentage of each electrical device belonging to the concert is analyzed, and the specific analysis method is: obtaining the appropriate use time of each type of electrical equipment from the local database, and extracting the appropriate use time of each electrical equipment belonging to the concert according to the model of each electrical equipment belonging to the concert. .

[0024] It should be noted that the local database is used to store the appropriate usage time of various types of electrical equipment, the aging power fluctuation percentage corresponding to each aging coefficient interval, the appropriate maximum power value of the mobile energy storage device, the excessive power hazard coefficient threshold, the power fluctuation threat coefficient threshold, the interval between two monitoring time points, the additional reserved safety percentage of energy storage, the maximum total energy storage value of a single mobile energy storage device, the maximum power value of a single diesel generator, the power safety reserve percentage, the electricity price of each power supply time period in the area where the concert is located, the current time point and the start time of the concert, and the appropriate charging value per unit time corresponding to each estimated number interval of the mobile energy storage device.

[0025] Based on the usage time of each electrical equipment in the concert , calculate the aging coefficient of each electrical equipment in the concert .

[0026] The aging power fluctuation percentage corresponding to each aging coefficient interval is obtained from the local database, and the aging power fluctuation percentage of each electrical equipment belonging to the concert is mapped.

[0027] It should be noted that the larger the aging coefficient, the greater the corresponding aging power fluctuation percentage. As the electrical equipment ages, the power becomes more unstable. For example, the power value of an audio device during normal use is 100W. After one year of use, the aging power fluctuation percentage is ±1%. At this time, the estimated instantaneous power range is 99W-101W.

[0028] In a specific embodiment of the present invention, the power supply mode of the concert in each performance time period is evaluated by a specific evaluation method: based on the estimated instantaneous power range of the concert at each monitoring time point in each performance time period, the maximum and minimum values of the estimated instantaneous power range of the concert at each monitoring time point in each performance time period are extracted, the power fluctuation threat coefficient of the concert in each performance time period is calculated, and the excessive power hazard coefficient of the concert in each performance time period is calculated.

[0029] Determine whether the power supply method for the concert during each performance period is mobile energy storage power supply or diesel generator power generation.

[0030] In a specific embodiment of the present invention, the power fluctuation threat coefficient of the concert in each performance time period is calculated by the following specific calculation method: the maximum value of the estimated instantaneous power interval at each monitoring time point in each performance time period of the concert is calculated. and minimum value , calculate the target power change value of the concert at each monitoring time point in each performance period ,in The function is to find the maximum value of the elements in the matrix.

[0031] Calculate the power fluctuation threat coefficient of the concert during each performance period , where j represents the number of monitoring times.

[0032] In a specific embodiment of the present invention, the calculation method of the excessive power hazard coefficient of the concert in each performance time period is as follows: obtaining the maximum suitable power value A of the mobile energy storage device from a local database.

[0033] Based on the maximum value of the estimated instantaneous power range at each monitoring time point in each performance period of the concert , calculate the power overload hazard coefficient of the concert in each performance time period .

[0034] In a specific embodiment of the present invention, the power supply mode of the concert in each performance time period is determined to be mobile energy storage power supply or diesel engine power generation, and the specific judgment method is: obtaining a power over-hazard coefficient threshold value from a local database; if the power over-hazard coefficient of the concert in a certain performance time period is greater than the power over-hazard coefficient threshold value, then the power supply mode of the concert in the performance time period is determined to be diesel engine power generation; otherwise, obtaining a power fluctuation threat coefficient threshold value from the local database; if the power fluctuation threat coefficient of the concert in a certain performance time period is greater than the power fluctuation threat coefficient threshold value, then the power supply mode of the concert in the performance time period is mobile energy storage power supply; otherwise, the power supply mode of the concert in the performance time period is determined to be diesel engine power generation.

[0035] Step 2 of the present invention analyzes and regulates the power consumption of the concert. By estimating the power of the concert at each monitoring time point in each performance time period and making predictions based on the estimated power changes and power values, the power supply mode of the concert in each performance time period is determined, and automatic power supply regulation is performed. The use of a hybrid power supply mode not only reduces the incidence of power outages caused by excessive voltage load changes, but also reduces the incidence of problems such as strobing lights and abnormal changes in sound tones due to heating of mobile energy storage devices, thereby ensuring the safety of the concert and the audience's experience.

[0036] Step 3. Pre-processing of electricity consumption for the concert: analyzing the estimated number of mobile energy storage devices and the estimated number of diesel generators for the concert, sending them to the concert manager, and pre-charging the energy storage devices for the concert.

[0037] In a specific embodiment of the present invention, the estimated number of mobile energy storage devices and the estimated number of diesel generators for the concert are analyzed by a specific analysis method: based on the maximum value of the estimated instantaneous power interval at each monitoring time point in each performance time period of the concert, the maximum value of the estimated instantaneous power interval at each monitoring time point in each energy storage power supply performance time period of the concert is extracted. , where p represents the number of each energy storage power supply performance time period, , q is a positive integer greater than 2.

[0038] Obtain the interval B between two monitoring time points, the additional reserved safety percentage D of energy storage, and the maximum total energy storage value E of a single mobile energy storage device from the local database, and calculate the estimated total energy storage value of the mobile energy storage device for the concert. , and calculate the estimated number of mobile energy storage devices for the concert ,in Indicates rounding up.

[0039] According to the maximum value of the estimated instantaneous power interval at each monitoring time point in each performance time period of the concert, the maximum value of the estimated instantaneous power interval at each monitoring time point in each diesel power generation performance time period of the concert is extracted, and the maximum estimated instantaneous power value F of all monitoring time points in the diesel power generation performance time period of the concert is extracted.

[0040] Obtain the maximum power value H and power safety reserve percentage G of a single diesel generator from the local database and calculate the estimated number of diesel generators for the concert .

[0041] It should be noted that the additional safety percentage of energy storage is set by the staff. In actual applications, the energy stored in the mobile energy storage device is often not just enough, and some margin needs to be left to prevent emergencies. The additional safety percentage of energy storage of the present invention can be set to 5%-20%, and a number can be selected therefrom.

[0042] It should also be noted that the power safety reserve percentage is set by the staff. In actual applications, the power provided by the diesel generator is often not just right, and more margin needs to be left to prevent emergencies. The power safety reserve percentage of the present invention can be set to 1%-10%, and a number can be selected therefrom.

[0043] In a specific embodiment of the present invention, the energy storage device pre-charging process for the concert is specifically performed as follows: the electricity prices of each power supply time period in the area where the concert is located are obtained from a local database, and the power supply time period with the lowest electricity price is marked as the first charging time period of the energy storage device for the concert, and it is determined whether charging only within the first charging time period of the energy storage device can meet the energy storage demand. If so, charging is performed within the first charging time period of the energy storage device. Otherwise, the power supply time period with the second lowest electricity price is marked as the second charging time period of the energy storage device for the concert, and it is determined whether charging within the first charging time period and the second charging time period of the energy storage device can meet the energy storage demand. The energy storage device is charged within the first charging time period and the second charging time period. Otherwise, the power supply time period with the third lowest electricity price is marked as the third charging time period of the energy storage device for the concert, and so on, until the energy storage device is pre-charged.

[0044] In a specific embodiment of the present invention, the determination of whether charging only within the first charging time period of the energy storage device can meet the energy storage demand is carried out by obtaining the current time point and the concert start time point from a local database, marking the time period from the current time point to the concert start time point as the concert target charging time period, and obtaining the duration K of the first charging time period of the energy storage device within the concert target charging time period.

[0045] Obtain the appropriate charging value L per unit time corresponding to each estimated number interval of the mobile energy storage device from the local database, map it to obtain the appropriate charging value per unit time of the mobile energy storage device for the concert, and calculate the total charging value of the concert in the first charging time period of the energy storage device. .

[0046] If the estimated total energy storage value of the mobile energy storage device of the concert is greater than the total charging value, it is determined that charging only during the first charging time period of the energy storage device cannot meet the energy storage demand.

[0047] Step 3 of the present invention is to pre-process the electricity consumption for the concert. By analyzing the estimated number of mobile energy storage devices and the estimated number of diesel generators for the concert, the power supply equipment is prepared in advance, and the mobile energy storage devices are charged during a time period with lower electricity prices, thereby reducing the financial consumption of the concert.
