Description

Technical Field

[0001] The present disclosure relates to the field of energy management, particularly to systems and methods for managing the power supply to telecommunication tower. Background

[0002] Due to the unavailability of a reliable power grid or continuous electric supply, telecommunication towers rely on Diesel Generators (DGs) for continuous power. At many sites, these DGs operate 24 / 7 to ensure uninterrupted telecommunication signal coverage. Often, multiple telecommunication towers are clustered together to enhance signal reach for subscribers.

[0003] To reduce diesel generator fuel consumption, many telecommunication towers are installing renewable sources like solar power, wind power, fuel cells etc. along with battery energy storage systems. These batteries are charged by one or more energy sources. When renewable power sources are unavailable or insufficient for battery charging, the diesel generator (DG) can be used alone or in combination with renewable sources. Once the batteries are fully charged, the DG is switched off. During the battery charging stage, depending on factors like the Genset rating, telecom tower load, and the number of batteries, the DG may operate at around 50-60% capacity. However, this approach increases DG operating hours and fuel consumption, which is suboptimal. Summary of the Disclosure

[0011] Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0012] Some embodiments of the disclosure describe managing power supply from a number of different power supplies to a telecommunication tower. The power supplies may include an energy storage device, a renewable power source and a diesel generator. A controller receives data concerning: a traffic load pattern of the telecommunication tower, energy / power available from the renewable power source; and a state of charge (SoC) of the energy storage device. The controller uses the received data to schedule the supply of power from each of the power sources to the telecommunications tower. The controller schedules power supply from the different power supplies to the telecommunication tower based upon the received data in order to handle the handle the traffic load, while minimizing use of the diesel generator and / or maintaining a desired SOC of the energy storage device.

[0013] FIG. 1 is an exemplary system 100 for managing the power supply to telecommunication tower 101 described herein. The system 100 includes a plurality of power supplies 105, 107, and 109 configured to power the telecommunication tower 101 and a controller 103. The plurality of power supplies 105, 107, and 109 may include at least one energy storage device 107, at least one renewable power source 105 and at least one diesel generator 109. The telecommunication tower 101 may be interconnected with the plurality of power supplies 105, 107, and 109 and the controller 103 via wired connections, wireless connections, or a combination of wired and wireless connection.

[0014] The renewable power source 105 may include at least one of a solar panel, wind turbine, hydroelectric power, or a combination thereof. The renewable power source 105 is a power source that produces energy from a source that is naturally replenishing but flow-limited such as, for example, wind, solar, geothermal, biomass, and hydropower. The renewable power source 105 may be an intermittent and non-dispatchable energy resource that generates electricity upon receiving an input from an energy flow (e.g., solar power, wind power, and / or the like). The renewable power source 105 may be a solar energy resource (e.g., a photo-voltaic energy resource), a wind energy resource (e.g., a windmill), a hydroelectric energy resource (e.g., a turbine), and / or another type of renewable energy resource. For example, the at least one renewable power source 105 may be a photo-voltaic (PV) energy source. The PV energy source includes a PV installation that includes a plurality of PV devices or solar cells that convert sunlight into electricity. The PV devices are arranged to form PV panels and multiple PV panels are arranged in PV arrays to form the PV installation. The PV installation converts sunlight into electricity and provides the electricity to the telecommunication tower 101 and / or to the at least one energy storage device 107 based on schedule instruction received from the controller 103.

[0015] The at least one energy storage device 107 may be a battery such as, for example, an electro-chemical battery (e.g., a sodium sulfur battery, a sodiumnickel chloride battery, a lithium polymer battery, a lithium ion battery, a lead-acid battery, a nickel-cadmium battery, and / or the like) and / or another type of battery suitable for storing energy and providing the stored energy to the telecommunication tower 101.

[0016] The least one diesel or gas or any other form of electric power generator 109 may be, for example, an alternating current (AC) generator, a permanentmagnet generator, an AC synchronous generator, or a switched-reluctance generator, configured to power the telecommunication tower 101. The least one diesel generator 109 may be configured to provide electricity to the telecommunication tower 101 and / or to the at least one energy storage device 107 based on schedule instruction received from the controller 103. The at least one diesel generator 109 may be configured to use either an inbuilt AC to DC rectifier or a separate AC to DC rectifier. This configuration allows the generator to convert the alternating current (AC) it produces into direct current (DC), which is necessary for powering the energy storage device 107. The flexibility to use either an inbuilt or separate rectifier ensures that the system can adapt to various requirements and conditions, providing reliable power to the energy storage device 107, such as a battery, for later use. Further, the at least one diesel generator 109 may be configured to power both the energy storage device 107 and telecom tower 101 based on scheduled instruction provided by the controller 103.

[0017] As shown in FIG 1, the system 100 may include the controller 103. The controller 103 may be configured to schedule the plurality of power supplies 105, 107, and 109 to the telecommunications tower 101 based on the received data. According to some implementations, the controller 103 may include one or more memories; and one or more processors, communicatively coupled to the one or more memories. The controller 103 may be interconnected with telecommunication tower 101 and the plurality of power supplies 105,107 and 109 though a wireless or wired connections or a combination of wired and wireless connections., enabling seamless communication and control. The controller 103 may be configured to receive data related to a traffic load of the telecommunication tower 101, an energy intensity of the renewable power source 105, and a state of charge (SoC) of the energy storage device 107.

[0018] In some implementations, the controller 103 may be configured to receive data related to a traffic load of the telecommunication towerlOl. The received traffic load of the telecommunication tower 101 may be defined as an amount of data and voice traffic that the tower 101 handles at any given time. This load can vary based on several factors, including the number of users connected to the telecommunication tower 101, the type of services being used (e g., voice calls, video streaming, internet browsing), and the time of day. Further, the traffic load of the telecommunication tower 101 typically follows a daily cycle, with peak usage times during the day when people are most active on their devices. This pattern can vary based on location, with urban areas often experiencing higher traffic loads compared to rural areas. Traffic load patterns are significantly influenced by several key factors. Time of day plays a crucial role, with peak hours typically occurring during morning and evening commutes, as well as lunch breaks. Day of the week also impacts traffic, with weekdays experiencing higher volumes compared to weekends. Additionally, special events or location such as large gatherings, concerts, or sports events can cause notable spikes in traffic.

[0019] In some implementations, the controller 103 may be configured to receive the energy intensity of the renewable power source 105. The energy intensity of the renewable power source 105 may be defined as the amount of power they can generate at a given time and measured in kilowatt-hours (kWh). The energy intensity of the renewable power source 105 can vary significantly due to factors such as time of day, weather conditions, and seasonal changes. Furthermore, the controller 103 may be configured to predicts the energy intensity of renewable power source 105 by analyzing historical energy intensity data and real time weather forecasts data. For example, the controller 103 may correlate past solar panel output with weather patterns to predict the future energy intensity availability. The controller 103 may be configured to use this prediction to schedule power supply to the telecommunication tower 101, allocate the renewable power source 105 efficiently, charge the energy storage device 107 when the surplus energy is available, and to minimize use of the diesel generator 109.

[0020] In some implementations, the controller 103 may be configured to receive the state of charge (SoC) of the energy storage device 107. The SoC provides real-time information on the available charge in the energy storage device 107. The controller 103 may be configured to continuous monitor SoC of the energy storage device 107 to reduces reliance on the diesel generator 109. The controller 103 may be configured to analyze historical SoC data of the energy storage device 107 to determine the time required time by the energy storage device 107 to discharge and recharge. Furthermore, the controller 103 may be configured to predict future SoC levels and optimize charging and discharging cycles, thus preventing damage to the energy storage device 107 and extending its lifespan. For example, if historical SoC data indicates that the energy storage device 107 typically discharges over a period of six hours under normal load conditions, the controller 103 may be configured to schedules charging of the energy storage device 107 during period of low traffic load or high energy intensity of the renewable power source 105. Further, the controller 103 may be configured to monitor the discharge of the energy storage device to ensure it does not fall below a particular SoC (e.g., 30% SoC).

[0021] In some implementations, the controller 103 may be configured to schedule the plurality of power supplies 105,107, 109 to the telecommunications tower 101 based on the received data.

[0022] The controller 103 may be configured to schedule the switch-off of at least one of the pluralities of power supplies 105, 107, 109, if the received traffic load is below a first predetermined level. The first predetermined level is a user-defined and related to the traffic load metrics of the tower 101. For example, if the received traffic load is below the first predetermined level, then the controller 103 may be configured to evaluates the necessity of maintaining active power supplies, particularly to conserve fuel. In another implementation, the controller may be configured to set the first predetermined level based on historical data. Furthermore, the controller may be configured 103 to the predict the traffic load based on the historical data from the similar events. For example, the controller 103 may predicts that traffic may drop below the first predetermined level at certain time of the events.

[0023] The controller 103 may be configured to determine whether the received traffic load is below the first predetermined level. If the received tariff load is below the first predetermined level, then the controller 103 may determine whether one or more nearest telecommunications tower can accommodate the traffic load. Thereafter, the controller 103 may be configured to divert the traffic load of the telecommunication tower 101 to the nearest one or more telecommunications tower based on the determination. Thereafter, the controller 103 maybe configured to switch off the plurality of power supplies 105,107, and 109 to the telecommunication tower 101 to save fuel of the at least one diesel generator 109.

[0024] In some implementations, the controller 103 may be configured to switch-off the diesel generator 109 and the energy storage devices 107 if the received energy intensity of the at least one renewable power source 105 is above a second predetermined level. The second predetermined level may be a level at which renewable power source 105 can provide sufficient power to the telecommunications tower 101.

[0025] When the received energy intensity of the renewable power source 105 is more than the second predetermined level, then controller 103 may be configured to switch off both the diesel generators 109 and the energy storage device 107. For instance, during daytime when the solar panels provide an energy intensity of 6kWh and telecommunication tower 101 requires only 3kWh, the renewable power source 105 can fully power the tower 101. In this scenario, the controller 103 may be configured to turn off the diesel generators 109 and the energy storage devices 107 to conserve fuel. In another scenario if the received energy intensity from the at least one renewable power source 105 is greater than the power required by the telecommunication tower 101, the controller 103 may be configured to schedule the charging of the energy storage device 107 in parallel. For example, if the received energy intensity from the at least one renewable power source 105 is 5kWh and telecommunication tower 101 need 3 kWh, the remaining 2kWh may be used to charge the energy storage device 107.

[0026] In yet another scenario, where the received energy intensity of the renewable power source 105 is significant but not sufficient to meet the entire traffic load of the telecommunication tower 101, the controller 103 may be configured to dynamically divert the traffic load to one or more near telecom tower to optimize the use of the renewable power source 105. For example, if the received energy intensity is 2kWh and telecommunication tower 101 requires 3kWh, then the controller 103 may be configured may divert a portion of the traffic to one or more nearby towers.

[0027] In yet another scenario, the controller 103 may be configured to predict the future traffic load based on historical data of the traffic load and weather conditions. The controller 103 may be configured to schedule the plurality of power supplies 105, 107 and 109 in anticipation of varying traffic load. For example, if the telecommunication tower 101 require 3kWh for certain duration, and the energy intensity of the renewable power source 105 at that is IkWh, then the controller 103 may be configured to divert partial traffic to one or more nearest towers and reduce power requirements to IkWh till time the energy intensity of the renewable energy reach the second predetermined level.

[0028] In some implementations, the controller 103 may be configured to switch-on the energy storage device 107 if the received energy intensity of the renewable power source 105 is below the second predetermined level and the received state of charge (SoC) of the energy storage device 107 is above a third predetermined level. The third predetermined level is a user defined level. In one implementation, the controller may be configured to dynamically set the third predetermined level based on the historical data related to the charging and discharging times and the life expectancy of the energy storage device 107.

[0029] Additionally, the controller 103 may be configured to predict the time required for the SoC to drop below the third predetermined level. Based on this prediction, the controller 103 may switch on the diesel generator 109 in advance to ensure continuous power supply. For example, if the SoC of the energy storage device 107 is expected to reach the third predetermined level within the next hour, the controller 103 may preemptively switch on the diesel generator 109 to start supplying power to the telecommunications tower 101 and charging the energy storage device 107. In another scenario, the historical data indicates that during the peak usage’s times, the SoC tends to drop rapidly, the controller 103 may adjust its scheduling to switch on the diesel generator 109 earlier in the day to prevent the SoC from falling below the third predetermined level.

[0030] The controller (103) may be configured to monitor the SoC of the energy storage device 107 and schedule the charging of the energy storage device 107 by the at least one renewable power source 105 and at least one diesel generator 109 based on the monitored SoC. The controller 103 may be configured to receive the energy intensity of the renewable power source 105. The controller may schedule the charging of the energy storage device 107 by the at least one renewable power source 105 if the received energy intensity of the renewable power source 105 is above the second predetermined level and the diesel generator is switch-off. Further, the controller 103 may schedule the charging of the energy storage device 107 by at least one the diesel generator if the received energy intensity of the renewable power source 105 may be below the second predetermined level and the SoC of the energy storage 107 below the third predetermined level.

[0031] In some implementations, the controller 103 may be configured to switch-on the at least one diesel generator 109 if the received energy intensity of the renewable power source diesel 105 is below the second predetermined level and the received state of charge (SoC) of the energy storage device 107 is below the third predetermined level. For example, on a cloudy day with low solar power availability, the controller 103 may detect the energy intensity from the renewable power source 105 is below the second predetermined level of 2kW. Similarly, the SoC of the energy storage device 107 is below the third predetermined level of 30%. The controller 103 may switch on the at least one diesel generator 109 to supply power to both the telecommunication tower 101 and the energy storage device 107. The diesel generator 109 continues to supply power until the SoC of the energy storage device 107 reaches 80%, at which point the controller 103 may switches off the diesel generator 109.

[0032] In some implementations, the controller 103 may be configured to prioritize the plurality of power supplies 105,107, and 109 to the telecommunication tower 101 based on environment impact, cost, and energy optimization. Furthermore, the controller 103 may be configured to prioritize power source as follows: first priority is assigned to the renewable power source 105, second priority to the energy storage device 107, and third priority to the diesel generator 109.The renewable power source 105 such as solar panels have minimal environmental impact compared to non- renewable source. They produce no direct emissions, contributing to a reduction in the carbon footprint of the telecommunication infrastructure. Furthermore, many jurisdictions have regulation and incentives favoring the use of the renewable power source 105. The energy storage devices 107 are second due to their flexibility and ability to ensure a continuous power supply by storing excess energy. However, the diesel generator 109 may be used as a last resort to minimize operation expenses and environment impact. The diesel generator 109 may be more expensive to operate due to fuel and maintenance costs. However, the diesel generator 109 may be serves as a reliable backup power source when the renewable power source 105 and the energy storage device 107 are insufficient to meet the demand.

[0033] In some implementations, the controller 103 may be configured to provide real time alerts and notifications of the status of the plurality of power supplies 105, 107, and 109 providing power to the telecommunication tower 101 and energy optimization to a remote management center. The alerts include information on power supply availability, SoC of the energy storage devices 107, operational status of the diesel generator 109, and any anomalies detected in the system 100. The anomalies can indicate potential issues or failure that need to be addressed to maintain optimal operational and reliability of the telecommunication tower 101. For example, loss of communication between controller 103, which could result in failure to share traffic load data and coordinate power supply management. By detecting these anomalies and provide timely alerts, the system 100 ensures that any issues can be quickly identified and addressed, maintaining the reliability and efficiency of the telecommunication tower 101.

[0034] FIG. 2 depicts a depicts a telecommunication tower divert traffic load to one or more nearest telecommunication tower. The telecommunication towers 201, 203,203, are positioned nearby and each equipped with the controller 207, 209, and 211, respectively. The controller 207, 209, and 211 may be configured to manage the power supplies to telecommunication tower 201, 203, and 203. Each telecommunication tower is powered by the plurality of power supplies. The plurality of power supplies may include at least one energy storage device, at least one renewable power source and at least one diesel generator. The telecommunication tower 207, 209, and 211 may be interconnected with the plurality of power supplies and controller 201, 203, and 203 via wired connections, wireless connections, or a combination of wired and wireless connection.

[0035] Further, the controller 207, 209, and 211 may be configured to continuously monitors the traffic load on its respective telecommunication tower 201, 203, and 203. When the traffic load of the telecommunication tower 201, is below the first predetermined level, the controller 207 may be configured to determine whether one or more nearest telecommunications towers 203 &205 can accommodate the traffic load. Thereafter, the controller 207 may be configured to divert the traffic load of the telecommunication tower 201 to the nearest one or more telecommunications tower based on the determination. Additionally, if the renewable power source at telecommunication tower 201 can only support a limited number of users, the controller 207 may be configured to divert full or partial traffic to telecommunication tower 203 and 205. For example, if the telecommunication tower 201 has the traffic load of 2000 user, and at that time the energy intensity from the renewable power source can support only 1000 users only. Then in this case, the controller 207 may be configured to check with controller 209 and 211, whether they can accommodate additional users. If each can accommodate an additional five hundred users, the controller 207 may be configured to divert five hundred users to each of towers 203 and 205 to align with energy availability.

[0036] FIG. 3 is a diagram illustrating an example of system 300 for managing the power supplies 305, 307 and 309 to telecommunication tower 301. The system 300 may include a controller 303. The controller 303 may be configured to schedule the plurality of power supplies 305, 307 and 309 to the telecommunications tower 301.

In Figure 3, three separate line of AC, DC and communication is shown as an example.

[0037] In some implementations, the PV power source 305 includes a PV installation that includes a plurality of PV devices or solar cells that convert sunlight into electricity. The PV 305 installation converts sunlight into electricity and provides the electricity to the telecommunication tower 301 and / or to the at least one energy storage device 307 based on schedule instruction received from the controller 303, in a manner similar to that described above with respect to Fig. 1.

[0038] The controller 303 may be configured to prioritize the plurality of power supplies 305, 307 and 309 to the telecommunication tower 301 based on environment impact, cost, and energy optimization. Furthermore, the controller 303 may be configured to prioritize power source 305, 307, and 309 as follows: first priority is assigned to the PV power source 305, second priority to the energy storage device 307, and third priority to the diesel generator 309.

[0039] FIG. 4 is a flowchart for a method for managing power supply to a telecommunications tower 101. As shown in Fig. 4, method 400 may include providing a plurality of power supplies 105,107 and 109 configured to power the telecommunication tower 101.

The renewable power source 105 may include at least one of a solar panel, wind turbine, hydroelectric power, or a combination thereof.

[0040] As further shown in Fig. 4, method 400 may include receiving, by a controller 103, data related to a traffic load of the telecommunication tower 101, an energy intensity of the renewable power source 105, and a state of charge (SoC) of the energy storage device 107. Further, the traffic load of the telecommunication tower 101 may be defined as an amount of data and voice traffic that the tower 101 handles at any given time. The energy intensity of the renewable power source 105 may be defined as the amount of power they can generate at a given time and measured in kilowatt-hours (kWh). The energy intensity of the renewable power source 105 can vary significantly due to factors such as time of day, weather conditions, and seasonal changes.

[0041] As further shown in Fig. 4, method 400 may include scheduling, by the controller 103, the plurality of power supplies 105, 107 and 109 to the telecommunications tower 101 based on the received data. The scheduling may include at least one of switching-off the plurality of power supplies 105, 107, and 109 if the received traffic load is below a first predetermined level.

[0042] As further shown in Fig. 4, method 400 may include scheduling the plurality of power supply to the telecommunications tower 101. The method 400 may include determining, by the controller, whether the received current traffic load is below the first predetermined level. The method 400 may include receiving, by the controller 103, traffic load status from the one or more nearest telecommunication tower 101. The method 400 may include determining, by the controller, whether the one or more nearest telecom tower can accommodate the current traffic load based on the received traffic load. The method 400 may include diverting the current traffic of the telecommunication tower 101 to the nearest one or more telecommunications tower based on the above determination. The method 400 may include switching off the plurality of power supply to the telecommunication tower 101 to save fuel of the at least one diesel generator 109, in a manner similar to that described above with respect to Fig. 1.

[0043] The scheduling may include switching-off the diesel generator 109 and the energy storage devices 107 if the received energy intensity of the at least one renewable power source 105 is above a second predetermined level, in a manner similar to that described above with respect to Fig. 1. The second predetermined level may be a level at which renewable power source 105 can provide sufficient power to the telecommunications tower 101.
