How to make base station (BS) green and energy efficient?

This paper aims to consolidate the work carried out in making base station (BS) green and energy efficient by integrating renewable energy sources (RES). Clean and green technologies are mandatory for reduction of carbon footprint in future cellular networks.

What are the components of a base station?

A typical base station consists of different sub-systems which can consume energy as shown in Fig. 4. These sub-systems include baseband (BB) processors, transceiver (TRX) (comprising power amplifier (PA), RF transmitter and receiver), feeder cable and antennas, and air conditioner ( Ambrosy et al., 2011 ).

Which metric is used to rank BS for switching-off priority?

The BS' transmission power requirement is used as the metric for ranking of BS for switching-Off priority, in their simple model. Authors proposed two criterion for selecting a BS to be switched of.

Is cellular communication the fastest growing component of telecom sector?

Cellular communication is the fastest growing component of telecom sector in particular and ICT in general ( Iqbal et al., 2014; Bian et al., 2013 ). It is envisaged that the global BS power consumption will grow from 49 TWh in 2007 to 98 TWh by 2020 ( Fehske et al., 2011 ).

How many Bs are in a 4 4 K M 2 LTE coverage area?

Simulations are done for a 4 × 4 K m 2 LTE coverage area for a total 16 BS placed uniformly. The results were compiled for 48 h, which showed 15–16 active BSs in peak hours and 1–2 BSs in night/off-peak hours, serving all users.

How does heat dissipation and thermal control technology affect energy storage system?

Abstract: The heat dissipation and thermal control technology of the battery pack determine the safe and stable operation of the energy storage system. In this paper, the problem of ventilation and heat dissipation among the battery cell, battery pack and module is analyzed in detail, and its thermal control technology is described.

Does guide plate influence air cooling heat dissipation of lithium-ion batteries?

Due to the thermal characteristics of lithium-ion batteries, safety accidents like fire and explosion will happen under extreme conditions. Effective thermal management can inhibit the accumulation and spread of battery heat. This paper studies the air cooling heat dissipation of the battery cabin and the influence of guide plate on air cooling.

Does guide plate influence air cooling heat dissipation?

Effective thermal management can inhibit the accumulation and spread of battery heat. This paper studies the air cooling heat dissipation of the battery cabin and the influence of guide plate on air cooling. Firstly, a simulation model is established according to the actual battery cabin, which divided into two types: with and without guide plate.

Does air-inlet and air-outlet mode affect the heat dissipation performance of battery pack?

Different structures and air-inlet and air-outlet modes will influence the heat dissipation performance of battery pack, , , , , , many researchers have launched these studies.

What is lithium-ion battery energy storage cabin?

Lithium-ion battery energy storage cabin has been widely used today. Due to the thermal characteristics of lithium-ion batteries, safety accidents like fire and explosion will happen under extreme conditions. Effective thermal management can inhibit the accumulation and spread of battery heat.

What is the air cooling effect of the battery cabin?

The working condition of module was 1C, and the air speed was set to 4m/s. The results show that the average temperature, maximum temperature and temperature difference in the battery cabin reduced by 4.57°C, 4.3°C and 3.65°C respectively when guide plate added. The air cooling effect of battery cabin was improved by adding guide plate.

How do waste heat-to-power technologies work?

Explore our handy tools Waste heat-to-power technologies recover energy from waste heat and convert it into electricity. However, the temperatures of waste heat streams are generally too low to generate electricity using traditional steam turbine technology.

What is waste-to-energy generation?

Waste-to-energy generation is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste, or the processing of waste into a fuel source. Incineration is the main waste-to-energy form of waste treatment.

What is a waste heat powered system?

Schematics of the waste heat powered system. The hot water coming out from the generator of absorption cycle is around 85 °C and can be used for space heating or residential water heating. An economizer is used in the WHP system. The hot water from ABC heats up water flow supplied to space heating coil or residential usage.

What is waste heat recovery (WHR)?

Through the integration of waste heat recovery (WHR) technologies such as heat exchangers, Organic Rankine Cycle (ORC) systems, thermoelectric generators, combined heat and power (CHP) systems, and steam turbine systems, it is possible to convert waste thermal energy into useful power, thereby reducing fuel consumption and associated emissions.

Are waste heat recovery technologies viable in marine energy systems?

The implementation of waste heat recovery (WHR) technologies in marine energy systems necessitates a thorough economic evaluation to determine their financial viability.

Can heat integration improve waste-to-power technologies?

Even though industries have their heat integration site plans to use as much energy as possible and reduce waste heat streams, the potential to expand waste-to-power technologies is still large.
