To meet the ever increasing mobile data traffic demand, the mobile operators are deploying a heterogeneous network with multiple access technologies and more and more base stations to increase the network.
The 5G base station is the core device of the 5G network, providing wireless coverage and realizing wireless signal transmission between the wired communication network and the wireless terminal. The architecture and shape of the base station directly affect how the 5G network is deployed.
The construction of the 5G network in the communication system can potentially change future life and is one of the most cutting-edge engineering fields today. The 5G base station is the core equipment of the 5G network, and the performance of the base station directly affects the deployment of the 5G network.
The architecture and shape of the base station directly affect how the 5G network is deployed. In the technical standards, the frequency band of 5G is much higher than that of 2G, 3G and 4G networks.

Abstract—The fifth generation of the Radio Access Network (RAN) has brought new services, technologies, and paradigms with the corresponding societal benefits. However, the energy consumption of 5G networks is today a concern.
This technical report explores how network energy saving technologies that have emerged since the 4G era, such as carrier shutdown, channel shutdown, symbol shutdown etc., can be leveraged to mitigate 5G energy consumption.
It also analyses how enhanced technologies like deep sleep, symbol aggregation shutdown etc., have been developing in the 5G era. This report aims to detail these fundamentals. However, it is far away from being enough, a revolutionized energy saving solution should be taken into consideration.
1. Introduction 5G base station (BS), as an important electrical load, has been growing rapidly in the number and density to cope with the exponential growth of mobile data traffic . It is predicted that by 2025, there will be about 13.1 million BSs in the world, and the BS energy consumption will reach 200 billion kWh .
To properly examine an energy-optimised network, it is very crucial to select the most suitable EE metric for 5G networks. EE is the ratio of transmitted bits for every joule of energy expended. Therefore, while measuring it, different perspectives need to be considered such as from the network or user's point of view.
The explosive growth of mobile data traffic has resulted in a significant increase in the energy consumption of 5G base stations (BSs). However, the existing energy conservation technologies, such as traditi.
The power consumption of a single 5G station is 2.5 to 3.5 times higher than that of a single 4G station. The main factor behind this increase in 5G power consumption is the high power usage of the active antenna unit (AAU). Under a full workload, a single station uses nearly 3700W.
To improve the energy eficiency of 5G networks, it is imperative to develop sophisticated models that accurately reflect the influence of base station (BS) attributes and operational conditions on energy usage.
Although the absolute value of the power consumption of 5G base stations is increasing, their energy efficiency ratio is much lower than that of 4G stations. In other words, with the same power consumption, the network capacity of 5G will be as dozens of times larger than 4G, so the power consumption per bit is sharply reduced.
The main factor behind this increase in 5G power consumption is the high power usage of the active antenna unit (AAU). Under a full workload, a single station uses nearly 3700W. This necessitates a number of updates to existing networks, such as more powerful supplies and increased performance output from supporting facilities.
The explosive growth of mobile data traffic has resulted in a significant increase in the energy consumption of 5G base stations (BSs).
Certain factors need to be taken into consideration while dealing with the efficiency of energy. Some of the prominent factors are such as traffic model, SE, topological distribution, SINR, QoS and latency. To properly examine an energy-optimised network, it is very crucial to select the most suitable EE metric for 5G networks.

BESS delivers a dependable mechanism for energy storage and on-demand redistribution, enhancing grid resilience which is vital for the region's progress.
However, ASEAN has many untapped markets for energy storage applications. Hence, to maximise the market potential and accelerate the low carbon transition in ASEAN, this policy brief recommends several enabling policies for energy storage.

Iron-based batteries offer enhanced thermal stability and safety, making them suitable for the ASEAN region despite their lower energy density and commercial immaturity. Zinc-based batteries, being cost-effective and environmentally friendly, are well-suited for hot climates, though they still face challenges with energy density and cycle life.
These innovations are pivotal for enabling behind-the-meter solutions in ASEAN, supporting a transition towards more sustainable and resilient energy systems. As technological advancements continue, a diversified approach using multiple battery chemistries will optimise BESS performance in Southeast Asia.
The renewables-based transformation would need a massive investment in electricity infrastructure to maintain the balance of supply and demand. ASEAN has adequate policies to positively influence the attractiveness of energy storage through renewable energy investment, both on-grid and off-grid.
Long-term energy plans provide strategic direction for integrating renewable energy and storage solutions. By fostering a supportive policy and regulatory environment, ASEAN countries can significantly enhance BESS adoption, ultimately improving energy security, grid stability, and renewable integration across the region.

Measurements of battery energy storage system in conjunction with the PV system. Even though a few additions have to be made, the standard IEC 61850 is suited for use with a BESS. Since they restrict neither operation nor communication with the battery, these modifications can be implemented in compliance with the standard.
Large quantities of generated electricity can be stored and retrieved anytime too little power is produced . Such a scenario can only be implemented when data is exchanged properly among a BESS, PV system and control system .
The system consists of three components: a control center, a PV system and a BESS. Depending on the PV system's output and supply forecast, the control center prompts the change of the incoming and charging power at the battery by transmitting the SetData and SetValues services.
The logical nodes of the battery system ZBAT and the battery charger ZBTC are responsible for battery data. The node ZBAT contains general information on the battery, including battery type, capacity and charging (power injection). They can also be used to perform logical node tests and to switch the system on and off.
The control center communicates with the PV system by a Modbus protocol and with the BESS by IEC 61850. The IEC 61850 data structures provided by the BESS were created beforehand by a configuration file. Fig. 5 presents a schematic of this structure. Fig. 5. use case “meeting the supply forecast”. 5.1.
