Detailed ways

Embodiments of the present application provide a power supply management method and a power supply management device for a base station, which are used to manage power supply of a base station and can improve user experience.

For ease of understanding, the following briefly introduces some technical terms involved in the embodiments of this application:

Renewable energy, including: solar energy, wind power, tidal energy, geothermal energy, etc., the following embodiments take the pure optical site as an example to introduce the power supply management method and power supply management device of the base station provided in the embodiment of this application. The power supply management method and power supply management device of the base station constitute limitations.

Embodiments of the present application are described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Those of ordinary skill in the art know that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

The terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein can be practiced in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having", as well as any variations thereof, are intended to cover a non-exclusive inclusion, eg, a process, method, system, product or device comprising a series of steps or modules is not necessarily limited to the expressly listed Instead, other steps or modules not explicitly listed or inherent to the process, method, product or apparatus may be included. The naming or numbering of the steps in this application does not mean that the steps in the method flow must be executed in the time/logic sequence indicated by the naming or numbering. The execution order of the technical purpose is changed, as long as the same or similar technical effect can be achieved.

Using renewable energy as the power supply for the site, on the one hand, saves energy and protects the environment, and on the other hand, can reduce the operating cost of the base station. However, since renewable energy mostly relies on the natural environment to produce electricity, the electricity production capacity fluctuates greatly due to the impact of the environment. For example, wind power generation is affected by the wind level, and solar power generation is affected by cloudy or sunny days. Therefore, when renewable energy is used to power the site, it is necessary to equip an energy storage battery to store part of the electric energy for use by the base station when encountering extreme weather. The battery capacity of the energy storage battery is generally based on the average power consumption of the base station and the power available to the base station. The duration of continuous online operation is the design of backup power duration.

Because the revenue contribution (APRU, Average revenue per user) of a single user of communication base stations (hereinafter referred to as base stations or sites) in remote areas is low, the return on investment (ROI, Return on investment) is low, and the return period is long, causing operators The willingness to invest in building a website is low, so it is necessary to reduce the investment cost of the website. To avoid extreme weather and increase the backup time, more energy storage batteries are required, which will increase the site investment cost, and the battery configuration has a large redundancy. Therefore, energy storage batteries are usually not equipped based on the longest backup time.

The pure optical site converts solar energy into electrical energy through the solar power generation system, and part of the electrical energy is stored in the energy storage battery to deal with scenarios such as cloudy and rainy days that cannot be generated through solar energy. As shown in Figure 1, when there are three consecutive rainy days, the remaining power of the energy storage battery continues to decline. Only the backup power for the duration of the rainy days is sufficient to support the operation of the base station until the power generation recovers. If the energy storage battery is configured based on the average power of the site for backup power for 48 hours (h), when the continuous rainy weather exceeds 48 hours, solar energy cannot be collected due to the exceeding backup time, and the site will experience repeated outages, seriously affecting customer experience.

The current hierarchical energy-saving measures generally determine different degrees of energy-saving based on the remaining power in the energy storage battery. For example, when the remaining power in the energy storage battery is When the remaining power in the battery falls below the lower low battery threshold, deep power saving measures are initiated.

The graded energy-saving measures are determined only based on the remaining power of the energy storage battery. If the remaining power of the energy storage battery is sufficient to support the operation of the base station equipment until the power generation capacity is sufficient, starting deep energy-saving measures to reduce the performance of the base station equipment will affect the user experience; if future production The power capacity continues to be insufficient. Even if the remaining power of the current energy storage battery is high, it may still cause users to disconnect in the future and affect the user experience.

The power supply management method of the base station provided in this application is used to solve the energy saving of the base station under the condition of limited power backup time, and improve user experience through reasonable energy saving measures.

The power supply management device compares the predicted weather data with the corresponding meteorological data in the power generation data screened in step 402, and judges whether the preset condition is met. Exemplarily, the preset condition is that the difference between the meteorological data is less than a preset threshold, specifically, it is judged whether the temperature difference is smaller than a preset threshold, such as 5%, and/or, whether the wind speed difference is smaller than a preset threshold, such as 5%. %. If so, then perform step 404, if not, then perform step 405;

404. Input the prediction model for learning, and the power supply management device will learn the power generation data that meets the preset conditions and the meteorological data corresponding to the power generation data to belong to the prediction model. Specifically, the prediction model can be the following formula:

Among them, P represents the power generation during the forecast period, n represents the number of iteration arrays, i represents the number of iterations of data, i ranges from 1 to the maximum n, and Pi represents the power generation of the i-th group. Considering system resources, optionally, n is set to 10, that is, iterates according to a maximum of 10 sets of data. The temperature factor t is set to indicate the degree of influence by temperature; the wind speed factor w is to indicate the degree to which the power generation is affected by wind speed; the attenuation factor k is to indicate the aging degree of photovoltaic panels at the predicted time, which is a time-related quantity, time migration, Photovoltaic panels are aging and power generation efficiency is affected; ki is the attenuation factor corresponding to the i-th group of data. According to the actual power generation learning, the temperature factor and wind speed factor will be continuously optimized, so that the calculated estimated power generation data will become more and more accurate. Optionally, if the data dimension included in the meteorological data increases, the formula can increase the dimension accordingly. It can be used to predict power generation and improve the accuracy of estimated power generation.

405. Estimate the power generation according to the predicted radiation value. If there is no historical power generation that meets the preset conditions, the power generation can be estimated based on the predicted radiation value. Specifically, it is based on the configuration of the power generation system in the base station and the radiation in the forecast meteorological data The value is calculated, and the configuration of the power generation system includes the configuration of solar panels in the solar power generation system, which is usually a known fixed value.

406. Determine the estimated power generation amount. Determine the estimated power generation according to step 404 or step 405 .

By querying the historical power generation data of the same season and similar periods, and filtering out some reference historical power generation whose difference between the historical weather data and the forecast weather data is less than the preset threshold, the weather conditions closest to the target working hours can be obtained Since the recorded historical data is the actual historical power generation of the site and the meteorological data monitored by the site, it can be used as a reference and has high accuracy when used to calculate the estimated power generation.

Meteorological data is usually predicted and recorded according to different periods (the specific duration of the period is not limited, for example, 1h), and the target working time usually includes multiple periods, so it can be accumulated through the estimated power generation in different periods. The method for determining the target working hours is introduced below.

Optionally, the target working time is a preset value, and the target working time may be longer than the backup time of the energy storage battery. Exemplarily, the backup time of the energy storage battery is 48 hours, and the target working time is 72 hours.

Optionally, the power supply management device determines the target working time according to the remaining power of the energy storage battery and the standby time. The power supply management device determines the backup duration according to the remaining power of the energy storage battery. The backup duration plus the preset backup duration is the target working duration. For example, the backup duration of the energy storage battery is 48 hours, and the backup duration is 12 hours. The working hours are 60h.

Optionally, the power supply management device determines the low power generation capacity time period in which the power generation capacity is lower than the preset threshold in the future preset time period according to the forecast weather data; and then determines the target work according to the current moment and the end time of the low power generation capacity time period duration. Exemplarily, if it is determined based on the forecast weather data that the next 24h to 50h will be cloudy and rainy (irradiation value is lower than the preset threshold), that is, the time period from 24h to 50h is a low power generation capacity time period, then the low power generation capacity time period The end time of 50h determines the target working time, and the target working time is 50h. Optionally, adding the preset standby time is the target working time. Exemplarily, the end time of the period of low power generation capacity is 50 hours, and the standby time is 12 hours, and the target working time is 62 hours.

302. Determine the estimated service power consumption within the target working hours;

The power supply management device determines the estimated service power consumption within the target working hours. It should be noted that there is no sequence between the execution of step 302 and step 301, and they may be executed successively or synchronously, which is not specifically limited here.

In an implementation manner, the power supply management device determines the estimated service power consumption within the target working time according to the historical power consumption information of the site. As shown in Figure 1, the traffic volume of the base station related to service power consumption often presents a certain pattern, so the service power consumption can be estimated based on the historical power consumption information of the site.

In an implementation manner, artificial intelligence (AI) numerical analysis is performed according to the historical power consumption information of the base station to obtain the rules of user load fluctuations. User load is the percentage of user traffic to the maximum capacity of the base station, as shown in Table 2, the historical power consumption information table below, which records the historical power consumption information of the base station. Specifically, the historical power consumption information specifically includes multiple base station power consumption values, and the time period corresponding to each power consumption value, base station configuration, and user load. User load is related to user traffic, and user behavior in the base station coverage area usually presents Certain rules, the change law of user load can be obtained through the historical power consumption information of the base station, as shown in the change of traffic volume over time in Figure 1, which shows the change law of business profile data. Optionally, the law of power consumption of the base station in different time periods is obtained by means of an interpolation averaging method. The base station configuration is issued by the base station, and the power supply management device can obtain the base station configuration.

The method also includes: the power supply management device determines the estimated user load according to the user load rule and the period covered by the target working time, the user load rule is determined according to historical service power consumption and historical base station configuration, and the user load rule includes multiple User load for the time period.

The power supply management device can calculate the estimated service power consumption within the target working time according to the change rule of the base station load and the configuration of the base station. The base station configuration includes the number of carriers and carrier power set by the base station. It can be understood that the estimated service power consumption can be changed by setting different base station configurations.

Table 2. Historical Power Consumption Information Table

base station configuration	period of time	Base station load (W)	Base station power consumption (W)
G2*10W+L1*20W	10:00-11:00	100%	268
G2*10W+L1*20W	12:00-13:00	50%	233
G2*10W+L1*20W	22:00-23:00	30%	192

Among them, G2*10W represents the configuration of 2 GSM carriers, and the power of each carrier is 10W; L1*20W represents one LTE carrier, and the power of each carrier is 20W.

303. Determine the estimated working time of the base station based on the estimated power generation, the estimated service power consumption, and the remaining power of the energy storage battery of the base station;

Based on the estimated power generation determined in step 301, the estimated service power consumption determined in step 302, and the remaining power of the energy storage battery of the base station, the power supply management device calculates the estimated working hours of the base station.

304. Send a notification message to the base station device according to the estimated working duration and the target working duration;

The power supply management device sends a notification message to the base station device according to the estimated working time and the target working time determined in step 303 . Firstly, the power supply management device determines an energy-saving measure according to the estimated working time and the target working time, and then sends a notification message to the base station equipment, where the notification message instructs the base station equipment to execute the energy-saving measure.

Optionally, if the estimated working time is greater than or equal to the target working time, the notification message carries information that no energy-saving operation is performed; if the estimated working time is less than the target working time, the power supply management device determines a target energy-saving measure, The target energy saving measure is used to instruct the base station equipment to execute the target base station configuration, the target base station configuration is used to update the estimated service power consumption, and the updated estimated operating time determined according to the updated estimated service power consumption is greater than or equal to the target operating time duration; the power supply management apparatus sends a notification message to the base station equipment, where the notification message is used to instruct the base station equipment to execute the target energy saving measure.

It can be understood that if the estimated working time is greater than or equal to the target working time, it means that the base station equipment has no risk of power failure within the range of the target working time estimated by the power supply management device; if the estimated working time is less than the target working time, it means that the power supply The base station equipment may be powered off within the target working hours estimated by the management device, and energy-saving measures need to be taken to avoid power outages as much as possible.

Optionally, if the difference between the target working time and the estimated working time is greater than a first threshold and less than or equal to a second threshold, the notification message carries a first instruction, and the first instruction is used to instruct the base station to Execute a first-level energy-saving measure; if the difference between the target working time and the estimated working time is greater than a second threshold, the notification message carries a second instruction, and the second instruction is used to instruct the base station to perform a second-level energy-saving measure, The power consumption of the base station equipment under the second-level energy-saving measure is smaller than the power consumption of the base station equipment under the first-level energy-saving measure.

The power supply management device sets at least two levels of energy-saving measures, and performs hierarchical energy-saving based on the difference between the target working hours and the estimated working hours, which can improve user experience on the basis of ensuring the operating hours of the base station.

In an implementation manner, the power supply management device determines different energy-saving measures based on the difference between the target working time and the estimated working time. Energy saving measures include GRAT (GSM radio access technology, GSM radio access technology) processing, URAT (UMTS radio access technology, UMTS radio access technology) processing, and LRAT (LTE radio access technology) processing. Implement hierarchical energy saving according to the impact on users, and the sequential energy saving measures include: closing redundant carriers, reducing carrier power, and turning off carriers in different periods of time. Optionally, disabling redundant carriers includes disabling carriers in descending order of standards, with priority disabling 5G carriers, followed by disabling 4G carriers, and finally disabling 3G carriers, and only keeping 2G carriers. Optionally, reducing the carrier power includes reducing the carrier power step by step, for example, reducing the carrier power by 10W each time, until the estimated working time calculated by the updated base station configuration is greater than or equal to the target working time. Optionally, the frequency and duration of different carrier shutdown periods can be set according to actual needs for switching off the carrier by time. The hierarchical energy-saving measures based on this method can minimize the impact on users and improve user experience.

It can be understood that the energy saving measures mainly reduce the output power of the RRU by reducing the power of the carrier and turning off the carrier to achieve the purpose of reducing energy consumption. The implementation of energy-saving measures has an impact on user experience. For example, if some carriers are turned off, the number of users connected and the uplink and downlink rates will be affected; if the power is reduced, the signal coverage will be affected. Therefore, hierarchical energy-saving measures can be implemented from the perspective of impacting customers, from small to large impact. Exemplarily, first, turn off the high-standard carrier, such as turn off 5G or LTE, to maintain basic access; secondly, turn off the redundant GSM carrier to ensure that user access is not affected, but it will affect the total number of access users; finally, Power reduction and coverage shrinkage may affect user access in some edge areas.

In an implementation manner, the power supply management device sending a notification message to the base station device according to the target working time and the estimated working time includes:

If the target working time is equal to the estimated working time, the notification message carries an instruction to work normally; if the difference between the target working time and the estimated working time is greater than 0 and less than the first threshold, the notification message Carrying an instruction to turn off redundant carrier frequencies; if the difference between the target operating time and the estimated operating time is greater than or equal to the first threshold and less than the second threshold, the notification message carries an instruction to reduce power, and the second The threshold is greater than the first threshold; if the difference between the target operating time and the estimated operating time is greater than or equal to the second threshold and less than the third threshold, the notification message carries an instruction to turn off the carrier by time period, and the third The threshold is greater than the second threshold. The difference between the target working hours and the estimated working hours may be expressed as a percentage of the difference between the target working hours and the estimated working hours in the target working hours.

Exemplarily, the first threshold is 10%, the second threshold is 20%, and the third threshold is 50%. Please refer to the hierarchical energy-saving measures shown in Table 3:

Table 3. Grading Energy Saving Measures

Among them, L0 represents the normal state, L1 represents the energy saving level 1, L2 represents the energy saving level 2, and L3 represents the energy saving level 3. Specifically, L0 corresponds to the normal configuration and scheduling of base station equipment, and no energy-saving measures are taken; energy-saving level 1 corresponds to turning off redundant carrier frequencies for GSM, turning off redundant carrier frequencies for UMTS processing, and turning off channel carriers for LTE processing. The impact of the service is to reduce the service capacity of the base station; the energy-saving level 2 corresponds to GSM processing to reduce the carrier power, UMTS processing to limit the available service power (that is, reducing the carrier power), and LTE processing to reduce the carrier power by reducing the pilot frequency and limiting the available service power. , the energy-saving measures of energy-saving level 2 will reduce the coverage of the base station; energy-saving level 3 corresponds to the GSM process of turning off the carrier by time period, the UMTS process of turning off the carrier by time period, and the LTE process of intelligently turning off the carrier. Energy-saving level 3 is a deep energy-saving measure. Basic functions, such as reporting alarms, etc.

Based on different energy-saving levels, the estimated working hours of the base station can be extended. For example, please refer to Table 4. In an implementation mode, the base station equipment adopts hierarchical energy-saving measures based on the notification message to realize the control of service power consumption. Reduce service power consumption and extend the working hours of base station equipment.

Table 4. Power Consumption Benefit Table of Classified Energy Saving Measures

Based on the above energy-saving measures, if the backup power of the energy storage battery is 300 ampere hours (A.h), after adopting different energy-saving measures, the benefits of extending the working hours of the base station are shown in Table 5 below:

Table 5. Service income table of graded energy-saving measures

energy saving level	power consumption	Battery	Backup time	energy saving benefits	service extension
L0	268	300	46	0	0
L1	239	300	52	10%	13%
L2	195	300	64	27%	39%
L3	170	300	72	36%	56%

It can be seen from the above table that the power supply management device sends a notification message to the base station equipment, and the notification message carries the energy-saving level mark, instructing the base station equipment to save energy through hierarchical energy-saving measures, which can extend service, reduce outage rate, and improve user experience.

It should be noted that steps 301 to 304 may be executed repeatedly, and optionally, power supply management is performed at a preset frequency, for example, once an hour.

Below, the flow of the power supply management method performed by the base station under extreme weather conditions is introduced. Please refer to Figure 8. Extreme weather conditions refer to weather conditions that will continue to affect the power generation level of the base station power generation system, such as continuous rainy days. When the power generation capacity of the base station When it is not enough to meet the power consumption requirements of the base station equipment, the power stored in the battery of the base station energy storage system can provide power for the base station equipment. If the extreme weather continues, the power of the energy storage system will gradually decrease, and the base station may be powered off, and the user will be disconnected. . The power supply management method of the base station provided in the embodiment of the present application specifically includes:

801. The station and energy linkage function starts. On the site side, obtain the current business model of the base station, as well as historical user load patterns; on the energy system side, obtain future forecast weather data and historical power generation information.

Based on the power generation forecast and business power consumption forecast, as well as the remaining power of the energy storage battery, the estimated working hours can be obtained. The end time of extreme weather such as rainy days can be judged by forecasting meteorological data. If the estimated working time is long enough to support the base station to work to the end time of rainy days (or the time to restore power generation capacity), then the estimated work can be judged If the duration meets the rainy day requirement, go to step 804, and if it is judged that the estimated working time does not meet the rainy day requirement, go to step 805.

804. If yes, take no action. That is, the base station does not perform energy saving measures. Step 801 is executed again after a certain period of time, for example, every 1 hour.

805. If not, the network management issues a hierarchical energy saving command to the base station. The hierarchical energy saving command instructs the base station to perform hierarchical energy saving measures. According to the difference between the estimated working hours and the duration of rainy days, the size of the power gap can be judged. If the difference is large, that is, the power gap is large, in-depth energy-saving measures should be issued to ensure the basic working capabilities of the base station; if the difference is small, that is If the power gap is small, mild energy-saving measures will be issued to reduce the impact on users on the basis of avoiding outages.

806. The base station executes hierarchical energy-saving measures. The base station executes the hierarchical energy-saving measures according to the hierarchical energy-saving command. It can be understood that the hierarchical energy-saving measures can set multiple energy-saving levels according to actual needs. The higher the energy-saving level, the lower the power consumption of the base station, and correspondingly, the impact on user services may be greater.
