Abstract
Green telecommunication tower primarily depends on renewable energy and energy efficiency technologies. This study presents a power consumption model to estimate the load demand of a telecommunication tower (TT) to improve energy efficiency. The method is based on field measurements of real-time data traffic load of the entire operated macrocell telecommunication tower to balance power supply and energy demand. This advanced method is investigated using HOMER Pro simulation and compared with a widely accepted technique called overall peak load method for a chosen case study. The comparison simulation results showed that by using the power consumption model method, the energy-saving efficiency at the TT is improved by 24.19% and the size of the overall system is decreased by 33.33%. Consequently, the annualized cost is reduced by 25.7%. This optimum performance contributes to the effective development of green telecommunication towers.
Highlights
The diversity of services provided by the mobile telecommunications industry has led to a significant increase in the capacity of data traffic and has increased energy consumption and CO2 emission [1]
telecommunication tower (TT) energy consumption is directly proportional to the capacity of data traffic load, which increases in the day and decreases at night
After entering all required input data, the HOMER Pro 3.8.3 software was run for the case study, firstly using the power consumption model based on real-time data, using the overall peak load estimation
Summary
The diversity of services provided by the mobile telecommunications industry has led to a significant increase in the capacity of data traffic and has increased energy consumption and CO2 emission [1]. TTs serve as terminal links between the subscribers and the data center, so cellular network operators (CNOs) constantly need building TTs to increase coverage areas and data transfer capacity for improving the quality of services. The challenge for CNOs is to provide the reliable power required to run TTs in an off-grid site where the electrical energy is unavailable without resorting to costly and environmentally unfriendly power systems. Appropriately sizing an off-grid solar power generation system requires accurate knowledge of the TT electricity demand including calculating total daily energy consumption and the peak load
