Description

Technical Field

[0001] This invention belongs to the field of mobile communication technology, and more specifically relates to a method, apparatus, electronic device and computer-readable medium for predicting the energy consumption of photovoltaic base stations. Background Technology

[0002] With the rapid development of my country's telecommunications industry and the explosive growth of mobile terminal devices such as smartphones, major operators are continuously increasing their investment in hardware infrastructure. To expand communication coverage, operators are actively promoting the construction of base stations and achieving full signal coverage in remote areas. Currently, a base station generally includes the following modules: power supply equipment, main equipment, environmental equipment, and other auxiliary equipment. The energy consumption of each module in a base station is as follows:

[0003] (1) Power supply equipment: accounting for about 5% to 10% of the total energy consumption. Most base station power supplies are switching power supplies. Power supply equipment is cascaded with electrical equipment, and there is a cascading effect between them in terms of energy consumption, which plays an important role in the energy saving process of base stations.

[0004] (2) Main equipment: accounting for approximately 50% to 80% of the total energy consumption. Main equipment refers to the core of the base station, consisting of the base transceiver station, transmitting and receiving antennas, and the feeder system. Its main function is to receive, transmit, and process mobile signals. This part of the equipment consumes the most energy during base station communication.

[0005] (3) Environmental equipment: accounting for about 10% to 25% of the total energy consumption. It mainly includes equipment such as air conditioners and humidifiers, which are used to regulate the temperature and humidity in the equipment room. During the operation of the base station, the air conditioning system needs to be turned on frequently in order to regulate the temperature in the equipment room. The energy consumption of these devices is also not negligible, and it is only lower than the energy consumption of the main equipment.

[0006] (4) Other auxiliary equipment: accounting for about 5% to 15% of the total energy consumption. Most of them are modules that do not perform core functions, including providing light sources and ensuring operation.

[0007] Currently, there are three main power supply methods for remote tower base stations: (1) building new power supply circuits to achieve mains power supply; (2) using oil pumping machines to generate electricity on-site and provide continuous power supply; and (3) using new energy power generation and regulating continuous power supply through energy storage.

[0008] In remote areas of Northwest China, new energy base stations primarily employ the third approach: powering the base station equipment with solar or wind power and using batteries as backup energy storage to power various communication devices, achieving integrated wind, solar, and energy storage power supply. During the day, when weather conditions are good, the power generation is sufficient to meet the energy needs of the base station equipment. However, during cloudy or rainy weather or at night without sunlight, the power generation is insufficient to meet the equipment's energy requirements. Therefore, battery energy storage is needed as a backup power source for short periods. If the equipment load is high or backup power is used for extended periods, it can lead to over-discharge of the batteries, causing irreversible damage. During specific time periods, such as nighttime to early morning, the communication service volume accessed by the base station is generally low, especially in remote areas where base stations have no communication service access at all, yet the communication equipment remains fully operational, resulting in significant energy waste. In extreme weather conditions, such as prolonged cloudy or rainy weather, or insufficient sunlight, if there is a lack of effective planning for the energy storage of the new energy photovoltaic base station, the batteries will continuously discharge and eventually lose power, causing the photovoltaic base station to shut down due to power shortage, resulting in serious consequences.

However, this does not preclude those skilled in the art from implementing the present invention with technical solutions that do not contain the aforementioned structures, performance, effects, or other features under specific circumstances.

For example, some operations / steps in the flowcharts can be decomposed, some operations / steps can be combined or partially combined, etc. Without departing from the inventive spirit of this invention, the execution order shown in the flowcharts can be changed according to the actual situation.

[0050] The box in the attached diagram Figure 1 Generally, these refer to functional entities, and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processing unit devices and / or microcontroller devices.

[0052] In the existing technology, the construction of new energy base stations in remote areas is still relatively backward in terms of energy saving and battery protection. The commonly used methods are as follows: (1) Using intelligent circuit breakers to realize remote control of power on and off. This solution has a single function and is relatively backward in terms of intelligence. It can only be manually controlled and cannot be automatically controlled. (2) Automatically switching on and off load equipment through battery voltage detection devices. This solution can achieve the purpose of protecting the battery. However, the level of intelligence is also relatively low. Power off conditions cannot be configured separately for each household. It cannot distinguish between important loads and non-important loads and cannot achieve differentiated backup power function. (3) It is impossible to effectively predict the electricity demand and photovoltaic power generation of photovoltaic base stations within a predetermined time window in the future, so as to rationally plan and allocate electricity to each module.

[0053] To address the aforementioned technical problems, this invention proposes a method for handling weak links in the power grid. By utilizing historical energy consumption data and historical photovoltaic power generation data from photovoltaic base stations, an energy consumption early warning model is established to predict whether the power generation and energy consumption of photovoltaic base stations will be balanced in the future. This effectively estimates and predicts the electricity demand of photovoltaic base stations, and then rationally plans and allocates electricity to each module, ensuring the long-term reliable operation of the base stations, saving energy consumption of photovoltaic base stations, and improving power utilization.

[0054] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0055] Figure 1 This is a schematic diagram of a photovoltaic base station energy consumption prediction method according to an embodiment of the present invention.

[0056] like Figure 1 As shown, this method includes:

[0057] S101. Obtain historical energy consumption data, and estimate the estimated energy consumption within a preset time period after the current time based on the historical energy consumption data.

[0058] In some embodiments, historical energy consumption data is first obtained, which may start from the current time. Daily business volume information for the previous month (calculated as four weeks) is obtained from the server, and the maximum daily business volume S per unit time for the previous four weeks is calculated. max (j,l), j = 1, 2, 3, 4, representing the week number, l = 1, 2, 3, ..., 7, representing the number of days in a week, setting the energy consumption level L. S This represents the ratio of energy consumed to complete the workload within a unit of time (taking 1 hour as an example) to the energy consumed to complete the maximum workload within that unit of time, expressed by the following formula:

[0059]

[0060] Among them, S uThis represents the energy consumption (S) required to complete the workload within a unit of time (1 hour) in a day. max This represents the energy consumption required to complete the maximum workload within a unit of time (1 hour) in a day. The energy consumption level L for each day and hour is calculated for the first 28 days. S (i,j,l), where i = 0, 1, 2, ..., 23, represents the number of hours, and the energy consumption level per hour per day over the past four weeks is obtained as L. S (i,J,l)=S u (i,J,l) / S max (j,l), in this embodiment, a total of 5 energy consumption levels are divided, and each energy consumption level has a different range. For example, L is the energy consumption level of the 15th hour of the 25th day in the first 28 days. S If the value of (i,J,l) is 0.8, then the energy consumption level of the 15th hour is level 4.

[0061] Based on historical data, the expected energy consumption level (L) for each day and hour over the next two weeks is calculated using the following formula. S-f (i,l), (taking a week as an example):

[0062]

[0063] The expected daily / hourly energy consumption level (L) for the next two weeks is obtained by weighting and averaging the energy consumption levels for each day and each hour over the previous 28 days. S-f (i,l).

[0064] S102. Obtain historical photovoltaic power generation data, and estimate the estimated power generation within a preset time period after the current time based on the historical photovoltaic power generation data.

[0065] In some embodiments, to obtain historical power generation data of photovoltaic base stations, the system first retrieves historical weather information from the server for the two weeks following the current date over the past four years, and converts it into historical expected photovoltaic power generation P. CP (m,k), k=1,2,3,4, representing the year, m=0,1,2….13, representing the number of days in two weeks. Then, based on weather forecast information, the daily weather for the next two weeks is obtained and converted into the expected photovoltaic power generation P. CF (m), during the conversion process, the expected power generation value is set according to different historical weather information. For example, the expected power generation value is set to 1 for sunny days, 0.5 for cloudy days, and 0.2 for rainy days, and is dynamically adjusted according to the actual situation.

[0066] After setting the historical expected power generation values, calculate the average expected photovoltaic power generation for each day over the next two weeks using the following formula:

[0067]

[0068] For example, if the current day is December 3rd, and we want to obtain the expected power generation for December 6th, we can use a formula to add the historical expected power generation values ​​for December 6th of each of the past four years, and then add them to the expected power generation value for the future December 6th converted from weather forecasts. We get a total of 5 expected values, and then divide them by 5 to get the average expected value. We can then use this method to obtain the expected power generation value for each day in the next two weeks.

[0069] After obtaining the expected daily power generation values ​​for the next two weeks, the estimated power generation expected by the photovoltaic base station for the next two weeks is calculated. First, the maximum daily power generation E of the photovoltaic base station is obtained. C Then, calculate the estimated power generation E for the next two weeks using the following formula. Total :

[0070]

[0071] That is, the product of the average expected photovoltaic power generation per day over two weeks and the maximum power generation of the photovoltaic base station in a single day, multiplied by 14 days.

[0072] S103. Establish an energy consumption early warning model, and estimate whether the energy consumption in the preset time period meets the early warning conditions based on the estimated energy consumption and estimated power generation.

[0073] In some embodiments, an energy consumption early warning model is established, and the estimated energy consumption and estimated power generation calculated in the previous steps are input into the energy consumption early warning model.

[0074] Obtain the current remaining stored power C of the photovoltaic base station GB-C This refers to the current remaining power of the base station's battery pack. A model indicator is set to determine whether the sum of the current remaining stored power and the estimated power generation within the preset time period is greater than the estimated energy consumption. If it is not greater, an early warning is issued.

[0075] Preferably, the model metrics in the embodiments of the present invention include:

[0076] 1) If This means that the sum of the current remaining stored power of the base station and the estimated power generation in the next two weeks is greater than the energy consumption Q required for the photovoltaic base station to operate at full load for one day. BS Multiplying by 14 days indicates that there will be sufficient power generation in the next two weeks, there will be no energy warning, and the system will operate normally.

[0077] 2) If This means that the sum of the current remaining stored power of the base station and the estimated power generation in the next two weeks is less than the energy consumption Q required for the photovoltaic base station to operate at full load for one day. BS Multiply by 14 days, but greater than the energy consumption E required to complete the minimum business volume within the next two weeks. minThe product of the energy consumption level and the estimated energy consumption level requires a mild warning, indicating that although there may be insufficient energy in the next two weeks, the system can operate with low power consumption based on the original business volume model.

[0078] 3) If This means that the sum of the base station's current remaining storage capacity and the estimated power generation over the next two weeks is less than the energy consumption E required to complete the minimum service volume over the next two weeks. min The product of the estimated energy consumption level and the energy consumption E required to complete the minimum business volume within the next week. min The product of the energy consumption level and the estimated energy consumption level indicates that there will be insufficient energy in the next two weeks, requiring a poisoning warning. The system can only guarantee low power consumption operation for one week based on the original business volume model. If normal operation is to be guaranteed for two weeks, energy consumption needs to be reduced or power generation needs to be increased.

[0079] 4) If the sum of the current remaining storage power and the estimated power generation in the next two weeks is less than the product of the energy consumption required to complete the minimum business volume in the next week and the estimated energy consumption level, it indicates that there will be a severe energy shortage in the next two weeks. Even if the system refers to the original business volume model, it will not be able to guarantee low power operation for one week. A severe warning is required, and the administrator should discuss solutions.

[0080] Preferably, the historical energy consumption data and historical photovoltaic power generation data are updated periodically, and the estimated energy consumption and estimated power generation are also updated. The updated estimated energy consumption and estimated power generation are then input into the energy consumption early warning model to update the parameters of the energy consumption early warning model, so as to ensure the accuracy of the model.

[0081] This invention utilizes historical energy consumption data and historical photovoltaic power generation data from photovoltaic base stations to establish an energy consumption early warning model to predict whether the power generation and energy consumption of photovoltaic base stations will be balanced in the future. It effectively estimates and predicts the power demand of photovoltaic base stations, and then rationally plans and allocates power to each module, ensuring the long-term reliable operation of the base station, saving energy consumption of photovoltaic base stations and improving power utilization.
